Question 1Planning and preparing for vehicle loading crane operations

Before a vehicle loading crane is set up at a new site, which document should be consulted first to confirm the crane's rated capacity at the planned boom length and radius?

  1. The operator's logbook of hours
  2. The crane's service logbook
  3. The site's traffic management plan
  4. The load chart supplied with the crane Correct answer.

Explanation

The load chart is the manufacturer's authority for what the crane can lift at each boom length, radius and configuration, so it must be checked before planning any lift. The logbook and site plans do not state capacity figures.

Question 2Planning and preparing for vehicle loading crane operations

A vehicle loading crane is to be set up on a compacted gravel hardstand beside a recently backfilled trench. What is the most important planning action before lifting?

  1. Ask the truck driver to stand on the outrigger pad
  2. Confirm the ground bearing capacity and assess the trench backfill Correct answer.
  3. Reduce the boom length to keep the load closer
  4. Increase the hydraulic pressure to compensate for soft ground

Explanation

Ground conditions govern whether outriggers can transfer load safely; backfilled trenches can collapse and cause the crane to overturn. Planning must confirm bearing capacity and, where needed, use spreader plates or relocate the crane.

Question 3Planning and preparing for vehicle loading crane operations

What is the primary purpose of using spreader plates under the outrigger pads of a vehicle loading crane?

  1. To level the crane when the ground slopes
  2. To protect the paint on the outrigger floats
  3. To stop the outriggers from retracting under load
  4. To spread the outrigger load over a larger ground area Correct answer.

Explanation

Spreader plates increase the contact area so the pressure applied to the ground is reduced, lowering the risk of the outrigger sinking or the ground failing. They are selected for ground pressure, not for cosmetics or levelling.

Question 4Planning and preparing for vehicle loading crane operations

When planning a lift, the operator calculates the total load as the weight of the item plus rigging. Why must the rigging weight be included?

  1. Because the load chart rating applies to the total suspended mass Correct answer.
  2. Because rigging weight only matters above five tonnes
  3. Because rigging reduces the crane's hydraulic oil temperature
  4. Because rigging weight is added to the counterweight

Explanation

Rated capacities in the load chart refer to everything hanging from the hook, including slings, spreader beams and shackles. Omitting rigging mass can push the lift beyond the rated capacity at that radius.

Question 5Planning and preparing for vehicle loading crane operations

A load's mass is unknown and there is no documentation. What is the most appropriate planning step?

  1. Use the crane's maximum capacity as the assumed mass
  2. Estimate conservatively high and verify by weighing if practicable Correct answer.
  3. Lift it slowly and watch the crane's reaction
  4. Assume a mass based on similar loads seen before

Explanation

Where mass is unknown, planning must err on the safe side and, where possible, obtain an actual weight from the supplier or by weighing. Trial lifting without a known mass risks overloading the crane and rigging.

Question 6Planning and preparing for vehicle loading crane operations

Which factor most directly reduces the rated capacity of a vehicle loading crane during a lift?

  1. Increasing the hydraulic oil level
  2. Increasing the working radius Correct answer.
  3. Increasing the engine idle speed
  4. Decreasing the ambient temperature

Explanation

Rated capacity falls as the radius increases because the load moment on the crane structure and stability grows. Oil level, temperature and idle speed do not change the charted capacity at a given radius.

Question 7Planning and preparing for vehicle loading crane operations

Before operating a vehicle loading crane near overhead powerlines, what should planning establish first?

  1. The colour of the insulators on the poles
  2. The voltage and the safe approach distance for the lines Correct answer.
  3. The wind direction on the day of the lift
  4. The number of workers on the site

Explanation

Planning for work near energised lines requires knowing the system voltage so the correct exclusion zone or safe approach distance can be applied, and whether isolation or a spotter is needed. Other details listed do not define the electrical hazard controls.

Question 8Planning and preparing for vehicle loading crane operations

What is the main reason for planning a crane lift so that the load travels the shortest practical path?

  1. To minimise the time the load is suspended and the exposure to hazards Correct answer.
  2. To keep the crane's hour meter reading low
  3. To reduce the fuel consumption of the crane engine
  4. To avoid needing to grease the slew ring

Explanation

A short, controlled load path limits the time people are under or near a suspended load and reduces the chance of striking structures or personnel. Fuel use and maintenance intervals are not the safety rationale.

Question 9Planning and preparing for vehicle loading crane operations

A site has soft ground where outriggers cannot achieve adequate support. Which planning control is most appropriate?

  1. Operate with outriggers partially extended to reduce pressure
  2. Extend the outriggers fully without pads and proceed
  3. Place timber offcuts under each pad without assessment
  4. Use engineered spreader mats or relocate the crane to firmer ground Correct answer.

Explanation

When ground bearing is inadequate, the plan must provide engineered load spreading or move the crane to ground that can carry the outrigger loads. Partial outrigger extension and unassessed packers do not reliably distribute load.

Question 10Planning and preparing for vehicle loading crane operations

Why should the crane's slew and travel controls be checked during the pre-operational inspection?

  1. To test the crane's maximum lifting capacity
  2. To confirm the crane responds correctly before a load is applied Correct answer.
  3. To verify the fuel gauge reading is accurate
  4. To warm the hydraulic oil to operating temperature

Explanation

Pre-operational checks confirm that controls, brakes and safety devices function correctly before the crane is committed to a lift. They are not a capacity test and are not done to warm oil or check fuel.

Question 11Planning and preparing for vehicle loading crane operations

Which information should a lift plan for a vehicle loading crane include?

  1. The crane's registration expiry date alone
  2. The site's rubbish collection schedule
  3. Load mass, radius, capacity, rigging and ground conditions Correct answer.
  4. Only the name of the crane operator

Explanation

A lift plan documents the load, the radius at which it will be handled, the crane's capacity at that radius, the rigging arrangement and the ground support conditions. Administrative details alone do not control the lift.

Question 12Planning and preparing for vehicle loading crane operations

A load is to be lifted over a walkway used by other trades. What planning control best manages the risk?

  1. Ask workers to look up when the crane is operating
  2. Schedule the lift for lunchtime without barricades
  3. Barricade the area and exclude people from beneath the load Correct answer.
  4. Instruct the dogger to whistle before each movement

Explanation

The area beneath a suspended load must be cleared and barricaded so people cannot walk under it. Warnings and timing alone do not remove the hazard of a dropped load.

Question 13Planning and preparing for vehicle loading crane operations

When is it acceptable for a vehicle loading crane to be operated without fully extended outriggers?

  1. When the operator is experienced
  2. Only when the load chart specifies ratings for that outrigger configuration Correct answer.
  3. When the crane is on level concrete
  4. Whenever the load is under one tonne

Explanation

Some cranes have charted ratings for partially extended or stowed outriggers, and those configurations may only be used within the charted limits. Otherwise outriggers must be fully deployed as specified by the manufacturer.

Question 14Planning and preparing for vehicle loading crane operations

What is the role of a spotter when a vehicle loading crane is working near a blind corner?

  1. To guide the load by hand as it moves
  2. To record the crane's lifting hours
  3. To warn the operator of approaching people and obstructions Correct answer.
  4. To operate the crane's outrigger controls

Explanation

A spotter provides the operator with information about hazards the operator cannot see, using agreed signals. The spotter must stay clear of the load and must not handle it or operate controls.

Question 15Planning and preparing for vehicle loading crane operations

Which weather condition most warrants reassessing a planned lift with a large sail-area load?

  1. High humidity in the afternoon
  2. Cold overnight temperatures
  3. Gusting wind acting on the load Correct answer.
  4. Light drizzle with no wind

Explanation

Wind acting on a load with large surface area increases the load moment and can cause the load to swing uncontrollably, so the lift plan must set wind limits and be reassessed. Drizzle, humidity and cold alone do not create the same effect.

Question 16Planning and preparing for vehicle loading crane operations

Why must the crane's boom be positioned so the load is lifted vertically rather than dragged sideways?

  1. Vertical lifts are required only for heavy loads
  2. Side lifting increases fuel consumption noticeably
  3. Dragging the load slows the crane's hydraulic cycle
  4. Side loading can exceed the boom's designed strength and destabilise the crane Correct answer.

Explanation

Crane booms and structures are designed for vertical lifting loads, and side pulling induces forces they are not rated for, risking structural damage or overturning. The requirement applies to all loads, not only heavy ones.

Question 17Planning and preparing for vehicle loading crane operations

What should be confirmed about the rigging before a lift proceeds?

  1. That each item is rated, inspected and suited to the load Correct answer.
  2. That the shackles are painted the same colour
  3. That the rigging was used most recently on another site
  4. That the slings are the longest available

Explanation

Rigging must have a known working load limit, be free of damage and be appropriate to the load's mass, shape and centre of gravity. Length, colour and recent use do not establish suitability.

Question 18Planning and preparing for vehicle loading crane operations

A load has its centre of gravity well off to one side. How should this affect planning?

  1. The crane must be operated at maximum speed to reduce swing
  2. The load should be lifted by one sling only
  3. The outriggers can be left retracted to save time
  4. The rigging must be arranged so the load hangs level and stays controlled Correct answer.

Explanation

An offset centre of gravity causes the load to tilt, which can shift load onto individual slings and make the load difficult to control. The rigging plan must account for it so the load lifts level and stays stable.

Question 19Planning and preparing for vehicle loading crane operations

What is the purpose of a pre-start toolbox talk before crane operations begin?

  1. To brief the crew on the lift plan, roles, signals and hazards Correct answer.
  2. To replace the need for a written lift plan
  3. To satisfy the crane's warranty conditions
  4. To record each worker's trade qualification

Explanation

A toolbox talk communicates the lift plan so everyone understands the sequence, their role, the communication signals and the hazards identified. It supports, but does not replace, the documented plan.

Question 20Planning and preparing for vehicle loading crane operations

Which of these is a recognised hazard when a vehicle loading crane is set up close to an excavation?

  1. The crane's paint fading in sunlight
  2. The load chart becoming inaccurate
  3. The crane's radio reception weakening
  4. The excavation wall collapsing under outrigger load Correct answer.

Explanation

Outrigger loads close to an excavation can surcharge the wall and cause it to collapse, so planning must consider the excavation's depth, support and distance from the crane. The other items do not create a crane safety hazard.

Question 21Planning and preparing for vehicle loading crane operations

What does the term 'working radius' mean in crane planning?

  1. The distance the crane can travel with a load
  2. The horizontal distance from the crane's slew centre to the load's centre Correct answer.
  3. The maximum height the boom can reach
  4. The length of the outrigger beam

Explanation

Working radius is measured horizontally from the crane's rotation centre to the centre of the load, and it determines the capacity read from the load chart. It is not a height, outrigger dimension or travel distance.

Question 22Planning and preparing for vehicle loading crane operations

A crane is rated at 3.0 tonnes at the planned radius. The load is 2.6 tonnes and the rigging is 0.3 tonnes. What should the operator conclude?

  1. The lift is well within capacity because the load alone is under three tonnes
  2. The total of 2.9 tonnes is within the rating but leaves little margin for dynamic effects Correct answer.
  3. The lift is unsafe because rigging must always be excluded from the total
  4. The crane can lift it because the rating applies to the load only

Explanation

The total suspended mass is the load plus rigging, which is 2.9 tonnes against a 3.0 tonne rating. That is within the chart but leaves only a small margin, so dynamic effects, wind and load swing need careful consideration.

Question 23Planning and preparing for vehicle loading crane operations

Why should the crane operator confirm the location of underground services before setting up outriggers?

  1. Underground services attract lightning during storms
  2. Buried cables improve the ground's bearing capacity
  3. Services maps are needed to calculate the load chart
  4. Outrigger loads can damage buried pipes, cables or tanks Correct answer.

Explanation

Concentrated outrigger loads can crush buried services, causing leaks, outages or injury, so service locations must be identified and the crane positioned clear or protected. Services do not affect the load chart or improve bearing.

Question 24Planning and preparing for vehicle loading crane operations

Which communication method should be agreed before a lift where the operator cannot see the landing area?

  1. Workers shouting from different positions
  2. The operator guessing based on engine noise
  3. A designated signal person using agreed hand or radio signals Correct answer.
  4. A mobile phone call to the site office

Explanation

Where the operator's view is obstructed, one designated signal person must relay directions using signals agreed at the briefing. Multiple or unclear sources of instruction create confusion and danger.

Question 25Planning and preparing for vehicle loading crane operations

A lift plan specifies a maximum wind speed of 10 m/s, but gusts reach 12 m/s during the lift. What is the correct action?

  1. Continue and add an extra sling for stability
  2. Continue but reduce the boom length slightly
  3. Continue because the average wind speed is below the limit
  4. Stop the lift and reassess before continuing Correct answer.

Explanation

Exceeding the plan's wind limit means the lift must stop and the conditions reassessed, because wind increases load moment and reduces control. Average speed, boom adjustments or extra slings do not make an out-of-limit lift acceptable.

Question 26Planning and preparing for vehicle loading crane operations

Under the general duty of care, who is responsible for identifying hazards before a vehicle loading crane is set up at a workplace?

  1. Only the crane operator
  2. Only the crane hire company
  3. Only the site's principal contractor
  4. The person conducting the business or undertaking Correct answer.

Explanation

Work health and safety law places the primary duty on the person conducting the business or undertaking, who must identify hazards and control risks so far as is reasonably practicable. Operators and hirers contribute to that process but do not carry the duty alone.

Question 27Planning and preparing for vehicle loading crane operations

What is the main purpose of a documented lift plan for a vehicle loading crane task?

  1. To list the names of all site visitors
  2. To record the operator's licence number
  3. To calculate the hire charges for the crane
  4. To provide a written record of how the risks of the lift will be controlled Correct answer.

Explanation

A lift plan sets out the load, the crane configuration, the radius, the ground conditions and the controls that make the lift safe. It is a planning and risk-control document, not an administrative or commercial record.

Question 28Planning and preparing for vehicle loading crane operations

Which document must be consulted to confirm the maximum capacity a vehicle loading crane can lift at a given boom length and radius?

  1. The vehicle registration certificate
  2. The site induction booklet
  3. The rigging gear register
  4. The crane's load chart Correct answer.

Explanation

The load chart, often called the rated capacity chart, gives the maximum capacity at each combination of boom length, radius and configuration. No lift should be planned without reference to the chart that applies to the crane as set up.

Question 29Planning and preparing for vehicle loading crane operations

A vehicle loading crane is to work on a recently filled trench. Which planning action is most appropriate before setup?

  1. Assume the fill will support the outriggers because it looks compacted
  2. Set the outriggers only on the side away from the trench
  3. Reduce the load by half and proceed without assessment
  4. Have the ground assessed and use spreader mats or a designed pad if needed Correct answer.

Explanation

Backfilled trenches can collapse or settle under outrigger loads, so the ground must be assessed and load spread over an adequate area. Spreader mats or engineered pads distribute pressure and reduce the risk of the crane tipping.

Question 30Planning and preparing for vehicle loading crane operations

In crane planning, what does 'boom length' refer to?

  1. The distance from the crane's rear to the front bumper
  2. The width of the outrigger spread
  3. The length of the boom from its pivot to the tip Correct answer.
  4. The height of the load above the ground

Explanation

Boom length is measured along the boom from its pivot point to the tip, and it determines the radius achievable at a given height. It is one of the variables used to read capacity from the load chart.

Question 31Planning and preparing for vehicle loading crane operations

Why should the planned landing area for a load be cleared before the lift begins?

  1. To speed up the crane's travel between lifts
  2. To allow the load to be set down without striking people or objects Correct answer.
  3. To reduce the wind loading on the boom
  4. To make room for the crane's stabilisers

Explanation

The landing area must be clear so the load can be lowered safely and so no one is placed at risk beneath or beside it. Planning the set-down point in advance also prevents uncontrolled movements at the end of the lift.

Question 32Planning and preparing for vehicle loading crane operations

Which item of personal protective equipment is specifically required when planning work under a suspended load?

  1. Safety boots
  2. A high-visibility vest
  3. A hard hat Correct answer.
  4. Hearing protection

Explanation

A hard hat protects the head from falling objects and is a minimum requirement wherever loads are suspended overhead. High-visibility clothing and safety boots are also common site requirements but do not address the falling-object hazard directly.

Question 33Planning and preparing for vehicle loading crane operations

What should the planner confirm about the crane's configuration before calculating the rated capacity for a lift?

  1. The fuel level in the crane's tank
  2. Whether outriggers are fully extended and the boom is at the planned length Correct answer.
  3. The colour of the crane's markings
  4. The number of staff on site that day

Explanation

Rated capacity depends on how the crane is configured, including outrigger extension and boom length. The load chart entry is only valid if the actual setup matches the configuration it describes.

Question 34Planning and preparing for vehicle loading crane operations

A vehicle loading crane must place a load on a roof where the operator cannot see the landing point. What planning measure best manages this?

  1. Rely on the operator judging the position by sound
  2. Raise the load quickly to reduce the time out of sight
  3. Use a trained dogger with agreed hand or radio signals Correct answer.
  4. Ask a nearby worker to watch without briefing

Explanation

When the operator cannot see the landing point, a trained dogger or rigger must direct the lift using a pre-agreed communication method. The signals and the person giving them should be confirmed during planning so the lift is controlled at all times.

Question 35Planning and preparing for vehicle loading crane operations

A load's rated mass is known, but its dimensions are large and the planner is uncertain of the centre of gravity. What is the most appropriate planning action?

  1. Attach the slings to one side to correct the tilt
  2. Determine the centre of gravity or treat the load as unbalanced and plan accordingly Correct answer.
  3. Proceed because the mass is within capacity
  4. Lift the load slightly and observe whether it tilts, then continue

Explanation

An unknown centre of gravity can cause the load to tilt, swing or overload one sling leg, so it must be established before the lift. If it cannot be confirmed, the lift should be planned as for an unbalanced load with appropriate controls.

Question 36Planning and preparing for vehicle loading crane operations

What is the purpose of checking the crane's slew lock and travel brake before a lift?

  1. To allow the boom to be extended further
  2. To reduce the load's swing radius
  3. To increase the crane's rated capacity
  4. To confirm the crane will stay in position and not drift during the lift Correct answer.

Explanation

Slew locks and travel brakes hold the crane steady so the load does not move unexpectedly during lifting. A crane that drifts or slews under load can place people and property at risk, so these controls are verified before work starts.

Question 37Planning and preparing for vehicle loading crane operations

Which planning consideration is most important when a vehicle loading crane will operate on a public road?

  1. Traffic management, including exclusion zones and permits Correct answer.
  2. The age of the crane's tyres
  3. The colour of the crane's warning lights
  4. The number of passengers in the crane cab

Explanation

Operating on or beside a public road requires traffic management so that passing vehicles and pedestrians are kept clear of the crane and its load. Permits, signage and exclusion zones are planned in advance with the relevant road authority.

Question 38Planning and preparing for vehicle loading crane operations

What is the purpose of a hazard identification and risk assessment specific to a crane lift?

  1. To record the operator's training history
  2. To determine the crane's resale value
  3. To identify foreseeable hazards and decide how each will be controlled before work starts Correct answer.
  4. To satisfy the crane manufacturer's warranty conditions

Explanation

A lift-specific risk assessment identifies what could go wrong and the controls that will be applied, such as exclusion zones, ground treatment and communication methods. It is a planning tool that must be completed before the lift, not a record-keeping exercise.

Question 39Planning and preparing for vehicle loading crane operations

A load is to be lifted from a truck parked on a slope. Which planning control is most appropriate?

  1. Lift the load quickly before the vehicle moves
  2. Have a worker hold the vehicle steady
  3. Chock the vehicle and confirm the crane can be levelled within the manufacturer's tolerance Correct answer.
  4. Reduce the load by removing packaging

Explanation

Crane manufacturers specify a maximum out-of-level tolerance, and operating beyond it can cause the load to swing and the crane to tip. Chocking the vehicle and verifying the setup is within tolerance are essential before lifting.

Question 40Planning and preparing for vehicle loading crane operations

What information should be gathered about the load before planning a lift?

  1. Its mass, dimensions, centre of gravity and lift points Correct answer.
  2. The delivery date
  3. The supplier's contact details
  4. Its colour and finish

Explanation

The mass, dimensions, centre of gravity and certified lift points determine how the load can be rigged and whether it is within capacity. Missing any of these details can lead to an overload or an unstable lift.

Question 41Planning and preparing for vehicle loading crane operations

Why should the planned path of a load be checked for overhead obstructions such as roof edges and signage?

  1. To calculate the crane's fuel use
  2. To determine the operator's break times
  3. To confirm the load will not strike or snag on them during the lift Correct answer.
  4. To decide which slings to use

Explanation

Striking an obstruction can damage the load, the crane or the structure and may cause the load to swing or fall. Planning the path confirms there is sufficient clearance throughout the lift.

Question 42Planning and preparing for vehicle loading crane operations

What should be confirmed about the crane's tyres and suspension before a lift that requires outriggers?

  1. That the tyres are inflated to the maximum possible pressure
  2. That the vehicle is parked facing downhill
  3. That the vehicle is stable and the suspension is not resting on its bump stops Correct answer.
  4. That the tyres are the cheapest available

Explanation

When outriggers are deployed, the vehicle's suspension should be relieved so the outriggers, not the tyres, carry the load. If the suspension bottoms out or the vehicle is unstable, the setup is not suitable for lifting.

Question 43Planning and preparing for vehicle loading crane operations

A site has a known underground gas main close to the planned outrigger position. What is the most appropriate planning response?

  1. Place the outrigger directly over the main to protect it
  2. Proceed because the outriggers spread the load
  3. Ask the gas supplier to turn off the main during the lift
  4. Locate the main precisely and relocate the setup or use a designed load-spreading system Correct answer.

Explanation

Outrigger loads can crush or damage buried services, causing leaks or explosions. The service must be located accurately and the setup moved, or the load spread over a designed system that keeps pressure off the main.

Question 44Planning and preparing for vehicle loading crane operations

Which factor should be confirmed about the crane's annual inspection before it is used for a planned lift?

  1. That the inspection cost was approved
  2. That the inspection report is stored in the cab
  3. That the inspection is current and the crane is free of defects Correct answer.
  4. That the inspection was done by the operator

Explanation

Cranes must have current inspections and be free of defects before use, with records available for verification. Using plant with an expired inspection or known defects is not permitted.

Question 45Planning and preparing for vehicle loading crane operations

What is the purpose of establishing an exclusion zone beneath and around a planned crane lift?

  1. To keep unauthorised people clear of the drop zone and swing path Correct answer.
  2. To allow the crane to travel faster
  3. To reduce the crane's working radius
  4. To improve radio reception on site

Explanation

An exclusion zone keeps people out from under the load and out of the area where the boom or load could swing or fall. It is a key control that must be set up and communicated before the lift starts.

Question 46Planning and preparing for vehicle loading crane operations

A crane is rated at 5.0 tonnes at the planned radius. The load is 4.2 tonnes, the rigging is 0.2 tonnes and the hook block is 0.1 tonnes. What is the correct planning conclusion?

  1. The lift exceeds capacity and must be replanned
  2. The lift is acceptable if the boom is shortened
  3. The lift is within capacity with 0.5 tonnes to spare Correct answer.
  4. The lift is acceptable if the wind is light

Explanation

Total load is 4.2 plus 0.2 plus 0.1, which equals 4.5 tonnes, leaving 0.5 tonnes below the 5.0 tonne rating. All components of the load, including rigging and hook block, must be added before comparing with the chart.

Question 47Planning and preparing for vehicle loading crane operations

During planning, the required radius is 8 m but the load chart at that radius shows capacity below the total load. Which planning option is most appropriate?

  1. Proceed and rely on the crane's safety system to stop the lift
  2. Reduce the rigging weight only
  3. Increase the radius to gain capacity
  4. Reduce the radius by repositioning the vehicle or use a larger crane Correct answer.

Explanation

Capacity generally falls as radius increases, so moving the vehicle closer or selecting a crane with adequate capacity at the required radius restores a safe margin. Relying on a limiter to stop an overload is not a substitute for correct planning.

Question 48Planning and preparing for vehicle loading crane operations

A lift plan requires the load to be slewed over a live traffic lane. Which combination of controls best manages the risk?

  1. Ask drivers to slow down and proceed
  2. Slew quickly to minimise exposure time
  3. Close the lane or use traffic control, set an exclusion zone and plan the slew path Correct answer.
  4. Rely on the crane's audible alarm

Explanation

The safest control is to remove traffic from beneath the load, supported by an exclusion zone and a planned slew path. Traffic control and lane closures prevent vehicles and people entering the drop zone.

Question 49Planning and preparing for vehicle loading crane operations

Two cranes are planned to lift a single load together. Which planning requirement is most critical?

  1. Each crane is rated for the full load independently
  2. The cranes are the same colour and model
  3. Both operators use the same radio channel
  4. A documented dual-lift plan with a nominated supervisor and agreed load sharing Correct answer.

Explanation

Multi-crane lifts require a documented plan that defines load sharing, a nominated supervisor and clear communication, because the load can shift between cranes. Assuming equal sharing without a plan can overload one crane.

Question 50Planning and preparing for vehicle loading crane operations

A planned lift will take place beside an embankment that shows signs of recent slumping. What is the most appropriate planning action?

  1. Have the embankment assessed and move the setup back or provide engineered support Correct answer.
  2. Place the outriggers close to the edge to shorten the radius
  3. Reduce the load and proceed from the same position
  4. Set up as planned because the crane is on firm ground

Explanation

Slumping indicates the ground is unstable and may not support outrigger loads, which can also undermine the embankment. Assessment and relocation or engineered support are needed before any lift proceeds.
