Question 1Lift Planning

Before making a lift with a lattice-boom crawler crane, the person directing the lift must confirm the load weight. Which value should be compared directly against the crane's capacity chart for the planned configuration?

  1. The total load, including rigging, hook block, and any attached lifting devices Correct answer.
  2. The load weight plus half the boom and jib weight
  3. The bare load weight taken from the shipping papers
  4. The rated capacity divided by the number of parts of line

Explanation

Capacity charts are rated for the gross load suspended below the boom tip, so the total load must include the load, slings, shackles, spreader beams, and the hook block. Deducting the hook block or rigging separately leads to overloading. The boom and jib are already accounted for in the chart's structural ratings.

Question 2Lift Planning

A lift plan calls for a crawler crane to travel with a suspended load. Which planning element is most directly affected by this decision?

  1. The color coding of the hand signals used by the signalperson
  2. The type of tag line material selected for the load
  3. The boom angle used for the static pick
  4. The crane's travel-path ground bearing pressure and the manufacturer's travel-with-load ratings Correct answer.

Explanation

Traveling with a load introduces dynamic and ground-pressure considerations that are not present in a static pick, and manufacturers publish separate travel ratings or may prohibit the practice. The plan must address ground bearing, path condition, and the applicable travel chart. Signal colors and tag line material do not drive the capacity decision.

Question 3Lift Planning

When preparing a lift plan, which document establishes the crane's rated capacities for a specific boom length, radius, and configuration?

  1. The load chart published by the crane manufacturer for that model Correct answer.
  2. The rigging catalog from the sling supplier
  3. The site-specific fall protection plan
  4. The operator's medical certification card

Explanation

Rated capacities come from the manufacturer's load chart for the specific crane model and configuration. No other document on a job site defines the crane's structural and stability limits. Rigging catalogs, fall protection plans, and certification cards serve entirely different purposes.

Question 4Lift Planning

A planner is determining the operating radius for a crawler crane pick. Which measurement correctly represents radius?

  1. The vertical distance from ground level to the boom tip
  2. The length of boom paid out from the tip to the load
  3. The distance from the boom foot pin to the load hook
  4. The horizontal distance from the crane's center of rotation to the center of gravity of the load Correct answer.

Explanation

Operating radius is measured horizontally from the crane's center of rotation to the vertical line through the load's center of gravity. Measuring from the boom foot or along the boom gives a different value and will produce an incorrect capacity. Vertical height is not part of the radius definition.

Question 5Lift Planning

A lift plan shows the crane will operate on compacted fill over a buried utility trench. What should the planner require before approving the lift?

  1. An increase in the number of parts of line to slow the hoist
  2. A verification of ground bearing capacity and assessment of the trench's effect on support Correct answer.
  3. A reduction in the boom length to shorten the lift
  4. An additional signalperson positioned at the boom tip

Explanation

Ground conditions govern whether the crane's outriggers or tracks can support the imposed loads, and a buried trench can create a void that collapses under load. The planner must verify bearing capacity and address the trench before approving the lift. Parts of line, boom length, and signalperson placement do not solve a support failure risk.

Question 6Lift Planning

Which item belongs in a written lift plan as a method of controlling swing of a freely suspended load?

  1. A designated tag line handler using a tag line attached to the load Correct answer.
  2. An increased hoist speed to shorten exposure time
  3. A heavier hook block to add inertia
  4. A second crane holding the load from the opposite side

Explanation

Tag lines controlled by a designated handler are the standard means of restraining rotation and swing of a suspended load. Using a second crane to hold the load creates a multi-crane lift that requires its own plan and is not a routine swing control. Added hook block weight and higher hoist speed do not control swing and may increase hazard.

Question 7Lift Planning

A planner is checking whether a planned pick exceeds 75 percent of the crane's rated capacity. What is the practical reason this threshold matters in lift planning?

  1. It determines whether the lift is classified as critical or ordinary, which drives the level of planning and oversight required Correct answer.
  2. It defines the required boom angle for the pick
  3. It establishes the minimum number of parts of line required
  4. It sets the maximum allowable wind speed for the lift

Explanation

Many lift-planning programs classify lifts above a percentage of rated capacity, commonly 75 percent, as critical lifts requiring additional engineering, review, and oversight. The threshold is a planning classification, not a wind limit, line-pull rule, or boom angle requirement. Recognizing the classification early prevents an under-planned critical lift.

Question 8Lift Planning

During planning, a crane's capacity chart shows a rating for a specific radius and boom length, and a note states the rating is based on 360-degree operation. How should the planner interpret this?

  1. The rating applies only during travel with a load
  2. The rating applies with the load positioned anywhere in the full rotation of the upperworks Correct answer.
  3. The rating applies only when the load is over the front of the crawler
  4. The rating applies only when the crane is on outriggers

Explanation

A 360-degree rating means the published capacity is valid with the upperworks positioned anywhere through a full rotation, subject to the chart's other conditions. It does not restrict the load to the front, require outriggers, or apply only during travel. Planners must confirm that the actual operating quadrant matches the chart note.

Question 9Lift Planning

A load will be lifted from a position where the crane must swing over a nearby energized power line. What is the most appropriate planning action?

  1. Post a signalperson under the line to warn the operator
  2. Increase hoist speed to minimize time near the line
  3. Establish the required approach distance and de-energize or relocate the line where feasible Correct answer.
  4. Rely on the operator to keep the boom below the line

Explanation

Power line hazards are addressed by maintaining the required minimum approach distance and, where feasible, de-energizing or relocating the line. Relying on operator judgment or a spotter beneath the line does not provide positive protection. Increasing speed near a line increases risk rather than reducing it.

Question 10Lift Planning

A planner is selecting rigging for a lift and must account for the sling angle. As the horizontal angle between the sling legs decreases, what happens to the tension in each leg for the same load?

  1. Tension in each leg decreases
  2. Tension in each leg increases Correct answer.
  3. Tension in each leg remains unchanged
  4. Tension becomes independent of the load weight

Explanation

As sling legs approach horizontal, the vertical component per leg drops, so each leg must carry more tension to support the same load. This is why sling angle factors increase the required capacity at shallow angles. Sling tension never becomes independent of the load weight.

Question 11Lift Planning

A lift plan for a two-crane pick must address which additional consideration that a single-crane lift does not?

  1. The color of the tag lines used on the load
  2. The number of signalpersons assigned to the site
  3. The type of footwear worn by the riggers
  4. The load distribution between the two cranes and the effect of any load shift during the lift Correct answer.

Explanation

Multi-crane lifts require an engineered plan that establishes how the load is shared, how the cranes are coordinated, and what happens if the load shifts or one crane takes more than its share. Tag line color, signalperson count, and footwear are not the defining engineering concerns of a two-crane pick.

Question 12Lift Planning

What is the primary purpose of including a lift sequence diagram or sketch in a lift plan?

  1. To record the operator's certification number
  2. To list the sling manufacturer's warranty terms
  3. To document the crane's maintenance history
  4. To show the planned positions, radii, and load path so the crew can visualize and verify the lift Correct answer.

Explanation

A sketch or diagram communicates the planned crane position, load position, radii, and travel path so the crew can verify the plan and identify conflicts. It is a planning and communication tool, not a maintenance log, certification record, or warranty document.

Question 13Lift Planning

A planner calculates that a pick requires a boom length that, at the required radius, falls between two published chart columns. How should the planner proceed?

  1. Interpolate directly between the two capacities
  2. Average the two capacities and add ten percent
  3. Use the higher capacity of the two columns
  4. Use the lower capacity of the two columns or the next longer boom length Correct answer.

Explanation

Unless the manufacturer expressly permits interpolation, the planner must use the more conservative published value, typically the lower capacity or the next longer boom length. Interpolating or averaging between columns can exceed the crane's actual rating. The chart governs, not an assumed linear relationship.

Question 14Lift Planning

Which factor in a lift plan most directly determines the required number of parts of line for a hoist?

  1. The load weight, the line pull available, and the reeving efficiency Correct answer.
  2. The number of tag lines attached to the load
  3. The boom angle at the start of the pick
  4. The color of the load and the site lighting

Explanation

Parts of line are selected so the load can be hoisted within the available line pull, accounting for reeving efficiency and friction. Load color, tag line count, and starting boom angle do not determine reeving requirements. The planner must confirm the selected reeving matches the load and the hoist's capacity.

Question 15Lift Planning

A lift plan identifies that the load's center of gravity is offset from its geometric center. What planning consequence follows?

  1. The load will hang tilted, so the rigging must be arranged to control the tilt and the pick points must be verified Correct answer.
  2. The crane's rated capacity increases because the load is unbalanced
  3. The radius can be ignored for this pick
  4. The load may be lifted without tag lines in all cases

Explanation

An offset center of gravity causes the load to hang at an angle, which changes sling tensions and can make the load difficult to control. The plan must address rigging arrangement and pick points so the load is stable. Capacity does not increase, radius still matters, and tag lines are typically more important, not less.

Question 16Lift Planning

What does the term 'boom deflection' mean when planning a lift with a long lattice boom?

  1. The bending of the boom under load, which can increase the actual radius beyond the planned value Correct answer.
  2. The settling of the crane's tracks into the ground
  3. The rotation of the upperworks during swing
  4. The stretching of the hoist rope under load

Explanation

Long booms deflect under load, moving the boom tip outward and increasing the actual operating radius compared with the unloaded geometry. Because capacity drops as radius increases, the planner must account for this effect. It is distinct from swing, rope stretch, and ground settlement.

Question 17Lift Planning

Which of the following is a legitimate reason to require a pre-lift meeting with the crew before a complex pick?

  1. To assign blame if the lift later fails
  2. To replace the need for a written lift plan
  3. To confirm roles, communication methods, the lift sequence, and stop-work criteria Correct answer.
  4. To satisfy a requirement to document the crane's fuel level

Explanation

A pre-lift meeting aligns the crew on roles, signals, sequence, and the conditions under which anyone may stop the lift. It supplements, and never replaces, the written lift plan. It is not a fuel record or a fault-assignment exercise.

Question 18Lift Planning

A planner is evaluating a pick near the edge of a slope. Which condition most increases the risk of a tipping failure?

  1. The use of synthetic slings instead of wire rope
  2. The use of a longer boom to increase reach
  3. The presence of a signalperson on the high side of the slope
  4. The crane's center of gravity moving toward the slope edge as the load is swung over that side Correct answer.

Explanation

Operating near a slope edge reduces the support available on that side, and swinging the load over the edge shifts the combined center of gravity toward the unsupported area. This combination raises tipping risk. Boom length, signalperson location, and sling type are separate considerations.

Question 19Lift Planning

What is the purpose of a load moment indicator or rated capacity limiter on a crane during a planned lift?

  1. To warn or stop the crane when the load approaches or exceeds the rated capacity for the operating configuration Correct answer.
  2. To control the swing brake automatically
  3. To record the operator's hours of service
  4. To measure the wind speed at the boom tip

Explanation

These devices monitor load and geometry and provide warning or limiting action when the crane approaches its rated capacity. They are a backup to, not a substitute for, proper lift planning. They do not measure wind, log hours, or operate the swing brake.

Question 20Lift Planning

A planner must determine whether a lift qualifies as a critical lift. Which combination of factors most strongly supports that classification?

  1. The lift uses a crane with a recently painted boom
  2. The lift uses a single sling instead of a basket hitch
  3. The lift occurs on a sunny day with light wind
  4. The lift exceeds a set percentage of rated capacity and involves personnel or a high-consequence area Correct answer.

Explanation

Critical lift criteria typically include high utilization of rated capacity, lifting over personnel or occupied structures, and high-consequence loads. Boom paint, weather, and hitch type alone do not define a critical lift. The planner should apply the site's written criteria.

Question 21Lift Planning

When a lift plan specifies a maximum wind speed, what is the planner's intent?

  1. To replace the need for tag lines
  2. To allow the operator to exceed capacity in light wind
  3. To set a limit beyond which the load's sail area and the boom's exposure make the lift unsafe to continue Correct answer.
  4. To guarantee the crane will not tip at any wind speed below the limit

Explanation

Wind limits address the added forces on the load and boom from wind, especially for loads with large sail area. Exceeding the limit can make the lift uncontrollable even if the crane is within its capacity rating. The limit does not guarantee stability at all lower speeds, replace tag lines, or permit overloading.

Question 22Lift Planning

A planner is calculating the total load for a pick that includes a spreader beam. How should the spreader beam be treated?

  1. As part of the rigging, included in the total load along with slings and hardware below the hook Correct answer.
  2. As part of the boom weight already in the chart
  3. As a separate load that does not affect capacity
  4. As part of the crane's deduct, subtracted from the load

Explanation

A spreader beam is rigging below the hook and its weight must be included in the total load compared with the capacity chart. It is not a crane deduct, a separate non-load, or part of the boom. Omitting it understates the load and can lead to overloading.

Question 23Lift Planning

Which statement best describes the planner's responsibility regarding the crane's configuration in the lift plan?

  1. The plan may leave configuration details to the operator's discretion at the time of the lift
  2. The plan should list only the load weight and nothing else
  3. The plan should specify the crane's paint color and decals
  4. The plan should state the boom length, jib configuration, counterweight, and reeving assumed in the capacity check Correct answer.

Explanation

The capacity check is only valid for the configuration assumed, so the plan must document boom length, jib, counterweight, and reeving. Leaving these to the operator at lift time risks a mismatch with the chart used. Load weight alone is insufficient, and cosmetic details are irrelevant.

Question 24Lift Planning

A planner is reviewing a lift where the load must be set on a roof beyond a parapet. Which planning element is most important for controlling the load as it clears the parapet?

  1. Increasing the hoist speed to clear the parapet quickly
  2. Removing the signalperson to reduce radio traffic
  3. Tag lines and a planned signal sequence to manage rotation and position as the load clears the obstruction Correct answer.
  4. Reducing the number of slings to simplify the rigging

Explanation

Clearing an obstruction requires controlled positioning, which depends on tag lines and a clear signal sequence between the rigger and operator. Faster hoisting, fewer slings, or removing the signalperson all reduce control and increase risk. The plan should anticipate the obstruction and specify how the load will be managed.

Question 25Lift Planning

Which of these best explains why the planner must consider the crane's counterweight configuration when using a load chart?

  1. Counterweight determines the color of the load chart
  2. Counterweight has no effect on capacity and is listed only for transport
  3. Counterweight sets the required approach distance to power lines
  4. Capacity ratings are published for specific counterweight configurations, and using a different counterweight changes the allowable capacity Correct answer.

Explanation

Load charts are issued for defined counterweight arrangements, and removing or altering counterweight changes stability and therefore allowable capacity. The planner must confirm the crane matches the chart's assumed configuration. Counterweight does not affect chart color or power line distances.

Question 26Lift Planning

A lift plan lists the total gross load. Which items must be included in that gross load figure?

  1. The load weight minus the capacity of the hoist drum
  2. The load weight plus the weight of all rigging and lifting attachments below the hook Correct answer.
  3. The load weight plus half the weight of the crane's boom
  4. Only the weight marked on the load's shipping tag

Explanation

Gross load is the sum of everything suspended below the hook: the load itself plus slings, shackles, spreader beams, lifting lugs, and any attached hardware. Capacity charts are rated against this gross figure, so omitting rigging weight understates the demand on the crane.

Question 27Lift Planning

When a lift plan is prepared, who is responsible for confirming that the crane's actual configuration matches what the plan and capacity chart assume?

  1. The signal person alone
  2. The person directing the lift, working with the operator Correct answer.
  3. The rigging supplier
  4. The site safety officer alone

Explanation

The lift director and operator jointly verify that boom length, jib, counterweight, outrigger spread, and reeving match the configuration used to derive chart capacity. A mismatch between planned and actual configuration invalidates the capacity calculation.

Question 28Lift Planning

A lift plan must identify the crane's position relative to the load and the set point. Which planning benefit does a drawn plan view provide?

  1. It shows whether all planned positions are reachable within the charted radius and swing arc Correct answer.
  2. It proves the crane has enough fuel for the shift
  3. It replaces the need for a pre-lift meeting
  4. It certifies the operator's qualification

Explanation

A plan view plots the crane, load pick point, and set point so the planner can confirm each position falls within the charted radius and that the swing path is clear. It is a geometric check on reach and travel, not a substitute for meetings or documentation.

Question 29Lift Planning

A planner is choosing outrigger matting for a crane set up on compacted fill. What is the purpose of the matting?

  1. To reduce the swing radius of the counterweight
  2. To spread the outrigger load over a larger bearing area and reduce ground pressure Correct answer.
  3. To increase the crane's charted capacity beyond the manufacturer's ratings
  4. To level the crane when the ground cannot be leveled

Explanation

Outrigger mats distribute the concentrated float load over more soil, lowering bearing pressure so the ground does not fail beneath the float. They do not raise the crane's ratings, which remain fixed by the manufacturer.

Question 30Lift Planning

What is the purpose of establishing barricades around the swing radius of a planned lift?

  1. To keep unauthorized personnel out of the area where the counterweight and rotating structure travel Correct answer.
  2. To indicate where the load may be set down
  3. To mark the boundary of the crane's charted capacity
  4. To define the wind speed limit for the lift

Explanation

The swing radius barricade keeps people clear of the tail swing and rotating superstructure, which can strike or crush anyone inside that zone. It is a personnel-exclusion control, not a capacity or load-placement marker.

Question 31Lift Planning

In a lift plan, what does the term 'dedicated spotter' or 'dedicated signal person' mean for the crew assignment?

  1. A worker assigned solely to observe and signal for that lift Correct answer.
  2. A worker who monitors wind speed only
  3. A worker who operates the outriggers
  4. A worker who also performs rigging duties during the same lift

Explanation

A dedicated signal person is assigned only to directing the lift and has no competing task, so signals are never missed or delayed. Combining signaling with rigging or other duties defeats the purpose of dedicating the role.

Question 32Lift Planning

A planner is reviewing the load chart and notes that ratings differ for 'over the front' versus 'over the side' operation. What does this distinction reflect?

  1. Differences in the operator's visibility
  2. Differences in the color of the crane's paint scheme
  3. Differences in structural strength and stability depending on which part of the chassis carries the load Correct answer.
  4. Differences in the load's center of gravity

Explanation

Chart ratings vary by operating sector because the chassis, outrigger, and boom are stronger in some directions than others, and stability differs as well. The planner must match the planned working arc to the correct chart sector.

Question 33Lift Planning

A lift plan calls for the load to be landed on a truck bed. What planning element ensures the load can be controlled as it is set down?

  1. A higher hoist line speed
  2. A second crane standing by
  3. A tag line attached to control rotation and sway during landing Correct answer.
  4. A longer boom than the chart requires

Explanation

Tag lines let riggers steady and orient a freely suspended load during the final descent so it lands squarely without swinging into people or structures. They are a control measure for the landing phase of the pick.

Question 34Lift Planning

A planner is preparing a lift plan for a pick that will be made at a radius of 40 ft with a 90 ft boom. The chart shows 12,000 lb at 40 ft and 10,500 lb at 45 ft. The gross load is 9,800 lb. What is the correct planning conclusion?

  1. The lift is unacceptable because the gross load exceeds the 45 ft rating
  2. The lift is acceptable because the chart value at 45 ft is not the governing figure
  3. The lift is acceptable because the gross load is below the 40 ft rating Correct answer.
  4. The lift is acceptable only if the operator reduces hoist line speed

Explanation

The governing rating is the one at the actual working radius, which is 40 ft, where the chart allows 12,000 lb. With a gross load of 9,800 lb the pick is within capacity at that radius, so the 45 ft figure does not control.

Question 35Lift Planning

A planner calculates a gross load of 8,400 lb and finds the chart rating at the working radius is 12,000 lb. The site requires a 75 percent capacity check for this lift. What is the result of that check?

  1. The check cannot be performed without the boom length
  2. The lift exceeds 75 percent because 8,400 divided by 12,000 is 70 percent
  3. The lift is below 75 percent because 8,400 divided by 12,000 is 70 percent Correct answer.
  4. The lift is exactly at the 75 percent threshold

Explanation

Dividing the gross load by the chart rating gives 8,400 / 12,000 = 0.70, or 70 percent of capacity. That is under the 75 percent threshold, so the lift passes the site's check at this radius.

Question 36Lift Planning

A lift plan specifies a two-leg bridle sling with legs at 60 degrees from horizontal, and the load is 6,000 lb shared equally. Which planning statement is correct?

  1. Each leg tension is less than 3,000 lb because two legs share the load
  2. Each leg tension equals 6,000 lb because the sling is doubled
  3. Each leg tension equals 3,000 lb regardless of angle
  4. Each leg tension is greater than 3,000 lb because the legs are not vertical Correct answer.

Explanation

As sling legs move away from vertical, tension rises above the simple share of the load. With legs at 60 degrees from horizontal, each leg carries more than its 3,000 lb vertical share, so the rigging must be rated for the increased tension.

Question 37Lift Planning

A planner must decide whether a lift requires a critical lift plan. Which set of conditions best supports that determination?

  1. The load is heavy relative to chart capacity, the lift is over occupied space, and the load is difficult to control Correct answer.
  2. The lift occurs in the morning and involves a single crane
  3. The load is light and the pick point is in an open yard
  4. The crane is new and the operator is experienced

Explanation

Critical lift criteria typically combine high utilization of chart capacity, exposure of people or critical facilities below the load, and loads that are hard to control or unusually valuable. Any strong combination of these factors pushes the lift into critical-lift planning.

Question 38Lift Planning

A planner is siting a crane on a site where an underground utility vault lies near one outrigger. What is the most appropriate planning action?

  1. Place the outrigger directly over the vault to spread load
  2. Assume the vault is strong enough because it is concrete
  3. Reduce the load weight by 10 percent and proceed
  4. Move the crane or bridge the vault so outrigger loads bypass it, and verify with the utility owner Correct answer.

Explanation

Underground structures may not be designed for outrigger point loads and can collapse, tipping the crane. The planner must relocate the crane or install bridging designed for the load, confirming the structure's capacity with its owner.

Question 39Lift Planning

A lift plan requires the load to be raised over a structure and then lowered on the far side. Which planning element is most important for this 'over-the-top' pick?

  1. Confirming that the boom tip clearance and the charted capacity at the farthest radius are both adequate throughout the swing Correct answer.
  2. Removing tag lines to reduce rigging time
  3. Selecting the shortest available sling
  4. Increasing the hoist line speed to shorten exposure

Explanation

An over-the-top pick requires the boom to clear the obstacle while the load passes above it, and the working radius grows as the load swings out. The planner must confirm both physical clearance and chart capacity at the maximum radius reached.

Question 40Lift Planning

A planner is evaluating whether the crane's boom will strike a building during the planned swing. Which planning method best addresses this?

  1. Shortening the slings to raise the load
  2. Relying on the operator's experience to stop the swing in time
  3. Plotting the swing path and boom envelope against the building in plan and elevation Correct answer.
  4. Limiting the load to half of chart capacity

Explanation

Checking clearance requires comparing the boom's physical envelope through the full swing against the obstacle in both plan and elevation. Plotting the path reveals interference that a capacity reduction or sling change would not correct.

Question 41Lift Planning

A planner is calculating total ground pressure under a crawler crane's track. Which factor most directly increases the bearing pressure on the soil?

  1. Increasing the length of the track
  2. Lowering the boom angle while keeping radius constant
  3. Adding a larger counterweight without increasing track bearing area Correct answer.
  4. Reducing the load weight

Explanation

Bearing pressure equals the total weight carried divided by the bearing area. Adding counterweight raises the total weight without enlarging the track area, so pressure on the soil increases.

Question 42Lift Planning

During planning, the planner learns the load will be picked from a truck parked on a slope above the crane. What is the primary concern?

  1. The operator's visibility will improve
  2. The truck's paint may be damaged
  3. The crane's fuel consumption will increase
  4. The load may shift or swing uncontrollably as it leaves the sloped surface Correct answer.

Explanation

A load breaking free from a sloped surface can swing toward the crane or shift suddenly as gravity takes over. The planner should require a level pick point or control measures that account for the load's movement on release.

Question 43Lift Planning

A planner is preparing a lift over an operating roadway that cannot be closed. Which planning control is most appropriate?

  1. Increase the hoist speed to reduce time over the roadway
  2. Plan the lift outside traffic hours or provide positive protection and traffic control beneath the load Correct answer.
  3. Schedule the lift during peak traffic to finish quickly
  4. Rely on the load's weight to discourage vehicles from passing

Explanation

When people or vehicles cannot be excluded from beneath a suspended load, the planner must either move the lift outside active periods or provide positive protection and traffic control. Neither speed nor the load's weight substitutes for excluding traffic.

Question 44Lift Planning

A planner is checking a lift where the crane will travel with a suspended load. What does the manufacturer's chart typically require for this operation?

  1. Use of the stationary ratings without any reduction
  2. Use of dedicated travel ratings or a specified capacity reduction, plus a prepared travel path Correct answer.
  3. Removal of the counterweight before travel
  4. Travel at the maximum permissible boom length

Explanation

Charts usually provide separate pick-and-carry ratings or require a reduction from stationary ratings, along with a firm, level travel path. Traveling under load without applying those provisions overstates the crane's capability.

Question 45Lift Planning

A planner is reviewing a lift in which the load's rigging creates an eccentric pull on the boom tip. What is the most appropriate planning response?

  1. Reduce the boom length to shorten the lever arm
  2. Evaluate side-loading limits and revise the rigging or crane position to eliminate the eccentric pull Correct answer.
  3. Ignore the side load because the chart accounts for all forces
  4. Increase the load weight in the calculation to compensate

Explanation

Charts are generally developed for freely suspended loads with vertical or near-vertical pull; side loading can overload the boom or structure in ways the chart does not cover. The planner should eliminate the eccentric pull through rigging or repositioning, or verify limits with the manufacturer.

Question 46Lift Planning

A planner must document the communication method for a lift in which the operator cannot see the load. What should the plan specify?

  1. That radio communication is optional
  2. That the operator will judge load position by sound
  3. The specific signaling method, the designated signal person, and a backup means of communication Correct answer.
  4. That the lift will proceed only when the operator guesses the load position

Explanation

When the operator loses sight of the load, the plan must name the signaling method, the dedicated signal person, and a backup communication path in case the primary fails. This ensures commands are unambiguous and continuous.

Question 47Lift Planning

A planner is evaluating a lift in which the load will be landed on a steel frame that deflects under load. What planning consideration applies?

  1. The deflection eliminates the need for tag lines
  2. The deflection of the receiving structure may change the load's final position and impose additional forces on the rigging Correct answer.
  3. The deflection has no effect on the lift
  4. The deflection increases the crane's charted capacity

Explanation

A receiving structure that deflects can allow the load to settle or shift as weight transfers, changing rigging tensions and final position. The planner should account for this movement and control the transfer of load.

Question 48Lift Planning

A planner is comparing two crane positions for the same pick. Position A requires a longer boom at a given radius; Position B uses a shorter boom at the same radius. What is the general planning implication?

  1. Capacity is identical because the radius is the same
  2. Position B generally yields higher capacity because less boom weight acts at the radius Correct answer.
  3. Capacity depends only on the load weight
  4. Position A generally yields higher capacity because the longer boom reaches further

Explanation

At the same radius, a longer boom adds weight and reduces the crane's ability to resist the load moment, so chart ratings generally fall. Choosing the shorter boom that still reaches the work usually preserves capacity.

Question 49Lift Planning

A planner is preparing a lift plan for a pick that will be made near the crane's maximum radius with a jib stowed. Which planning assumption is most important to verify?

  1. That the load's shipping weight is accurate to the pound
  2. That the operator has previously made a similar pick
  3. That the wind will be calm on the day of the lift
  4. That the chart rating used corresponds to the actual boom length, jib condition, and counterweight in place Correct answer.

Explanation

Near maximum radius the margin between demand and capacity is small, so the chart rating must match the crane's actual boom length, jib stowage, and counterweight. Any mismatch between planned and actual configuration invalidates the rating.

Question 50Lift Planning

A planner is reviewing a lift where the crane must be set up on a steel deck spanning between beams. What analysis is most directly required?

  1. Confirming that the crane's horn works
  2. Confirming that the load weighs less than the deck's own weight
  3. Confirming that the deck can carry the outrigger float loads at their actual positions and that the beams are adequate Correct answer.
  4. Confirming that the deck's surface is painted

Explanation

Outrigger floats impose concentrated loads on the deck, and the supporting beams must be checked for those point loads at their actual locations. The deck's structural adequacy, not its finish or the crane's accessories, is the governing question.
