Question 1Plan and prepare work

You are planning to install a personnel and materials hoist at a new construction site. What should you do first to plan and prepare the work?

  1. Ask the crane crew to decide where the hoist should go
  2. Order the concrete counterweights before checking the base
  3. Erect the hoist immediately so the first shift can use it
  4. Review the site safety plan and consult the principal contractor about hazards and access Correct answer.

Explanation

Planning must begin with the site's safety management information and consultation with the person who has management or control of the workplace, so hazards, access routes and services are identified before equipment is positioned. Ordering materials or erecting first bypasses that risk assessment and can commit the site to an unsafe location or base.

Question 2Plan and prepare work

Before a personnel and materials hoist is used at the start of each shift, which check must be made?

  1. Test that gates, interlocks and upper limit switches operate correctly Correct answer.
  2. Check that the hoist's warning sign is facing the street
  3. Record the number of workers who will use the hoist that day
  4. Confirm the hoist has been painted in site colours

Explanation

Daily pre-start checks must confirm that safety devices such as gate interlocks and limit switches function correctly, because these prevent the car from moving with a gate open or overrunning the top landing. Any defect found must be reported and the hoist taken out of service until it is repaired.

Question 3Plan and prepare work

Which item must be included in the emergency plan for a personnel and materials hoist?

  1. A roster of workers to clean the hoist car
  2. The colour code for the hoist's load signs
  3. The delivery schedule for replacement parts
  4. A documented method to rescue people trapped in a stalled car Correct answer.

Explanation

The emergency plan must address foreseeable emergencies, including a power failure or mechanical fault that leaves people trapped, and must set out the rescue method, trained rescuers and communication arrangements. Housekeeping rosters and parts schedules do not provide an emergency response capability.

Question 4Plan and prepare work

You are preparing a base for a hoist mast on compacted fill beside an excavation. Which action best controls the risk of settlement or collapse?

  1. Assume the fill is adequate because it was compacted by the earthmoving contractor
  2. Start erection and monitor the base for movement during the first week
  3. Place timber packing under the base to spread the load without any assessment
  4. Obtain an engineer's design confirming the base can support the hoist's loads and the ground is stable Correct answer.

Explanation

Hoist bases and their supporting ground must be designed to carry the imposed loads, including wind and dynamic effects, and an engineer's footing design is the reliable way to confirm that fill next to an excavation is suitable. Monitoring after erection does not provide that assurance and allows a collapse to occur while people are using the hoist.

Question 5Plan and prepare work

A site plan shows the hoist landing close to the building edge and over a basement. What planning information should you obtain before fixing the hoist position?

  1. Structural details confirming the slab and basement can carry the hoist loads Correct answer.
  2. The paint code for the landing gates
  3. The names of the workers who will use the hoist
  4. The delivery times for the scaffold planks

Explanation

Placing a hoist over a basement or at a slab edge introduces concentrated loads and a risk of structural collapse, so the planner must confirm the supporting structure's capacity from drawings or engineering advice before committing to that location. The other items do not affect structural adequacy.

Question 6Plan and prepare work

During pre-start planning, the forecast shows strong gusting wind. What should you plan to do when wind speeds reach the manufacturer's stated limit?

  1. Continue at reduced speed while the operator watches the load
  2. Add extra weight to the car to make it more stable
  3. Stop hoist operation, secure the car and follow the manufacturer's high-wind procedure Correct answer.
  4. Ask workers to hold the landing gates closed while loads are moved

Explanation

Hoists must be operated within their designed wind limits, and once the manufacturer's threshold is reached, operation must stop and the specified high-wind securing procedure followed to prevent structural overload or uncontrolled movement. Reducing speed or holding gates manually does not reduce the wind load on the mast and car.

Question 7Plan and prepare work

Where should the exclusion zone be established around a hoist during planning?

  1. At the site entrance so visitors are warned
  2. Under and around the hoist where loads or parts could fall, marked and barricaded Correct answer.
  3. Inside the hoist car so workers stand clear of the doors
  4. Only around the base of the mast, one metre out

Explanation

Planning must define a barricaded exclusion zone covering areas where a falling load, component or debris could strike people, and must prevent unauthorised access beneath the hoist. A zone limited to the mast base, or placed elsewhere, leaves the drop zone unprotected.

Question 8Plan and prepare work

A load chart on the hoist states a maximum rated capacity of 1000 kg. A pallet of tiles weighs 940 kg, the pallet itself weighs 45 kg and an attached spreader beam weighs 30 kg. What planning decision should you make?

  1. Load the pallet, because 940 kg is below the rated capacity
  2. Do not load as planned, because the combined total exceeds the rated capacity Correct answer.
  3. Reduce the load by removing the spreader beam during the lift
  4. Load the pallet and check the hoist after the lift

Explanation

The rated capacity applies to the total suspended load, including the pallet and any lifting attachments, so the planner must add all of these items and keep the total within the chart value. The combined mass here is 1015 kg, which exceeds the 1000 kg rating and must not be lifted as planned.

Question 9Plan and prepare work

You plan a lift where the operator cannot see the landing level. What is the correct communication arrangement?

  1. Let the operator guess the position from the load line marks
  2. Rely on workers at the landing to shout instructions
  3. Use a mobile phone call with no backup and continue if the call drops
  4. Use a competent signaler with agreed signals and stop the lift if communication is lost Correct answer.

Explanation

Where the operator's view is obstructed, a competent signaler must maintain continuous communication using agreed signals, and the lift must stop if that communication fails. Shouting, guessing or an unreliable single phone link does not give positive control of the moving car or load.

Question 10Plan and prepare work

You find a hoist on site marked 'materials only'. The supervisor wants to use it to lift two workers. What is the correct planning response?

  1. Allow it after adding a sign that says 'persons permitted'
  2. Refuse the use, because a materials-only hoist is not designed or certified to carry people Correct answer.
  3. Allow it if the load chart shows spare capacity
  4. Allow it if the workers wear harnesses and the lift is short

Explanation

Only hoists designed and certified for personnel may carry people, with the required gates, interlocks and fall protection; a materials-only unit lacks those features regardless of spare capacity or harness use. Changing signage cannot alter the hoist's design category or make it compliant for lifting people.

Question 11Plan and prepare work

Before planning the erection of a personnel and materials hoist, which information should be obtained first?

  1. The manufacturer's instructions Correct answer.
  2. A generic rigging handbook
  3. The supplier's brochure
  4. The site weather forecast

Explanation

Planning must start from the specific manufacturer's instructions because they set the erection sequence, foundation, tie and capacity requirements for that model. Generic documents cannot confirm the hoist's limits or configuration.

Question 12Plan and prepare work

When planning each landing for a personnel and materials hoist, which feature is required?

  1. A fixed ladder to the ground
  2. An interlocked gate with edge protection Correct answer.
  3. A painted warning line on the floor
  4. A materials storage rack beside the gate

Explanation

Landings must be planned with gates that are interlocked so the hoist cannot move unless the gate is closed and secure, plus edge protection to prevent falls. These features control the main landing hazards before work starts.

Question 13Plan and prepare work

Before a hoist mast is tied to a building, which consultation is most important?

  1. The electrical supplier and plumber
  2. The building owner and structural engineer Correct answer.
  3. The site first-aider and storeperson
  4. The scaffolding subcontractor and traffic controller

Explanation

Ties transfer mast loads into the building structure, so the building owner and a structural engineer must confirm suitable anchor locations and load capacity. The manufacturer's tie requirements also need to be checked against the actual structure.

Question 14Plan and prepare work

When planning the electrical supply for a hoist, which arrangement best supports safe isolation during maintenance?

  1. A dedicated isolator that can be locked off Correct answer.
  2. An extension lead across the walkway
  3. A plug shared with site lighting
  4. A switch inside the site office

Explanation

A dedicated isolator that can be locked off allows the hoist to be isolated positively and the isolation to be secured while maintenance is done. Shared plugs and improvised leads create confusion and do not provide reliable lockout control.

Question 15Plan and prepare work

A hoist landing is planned close to an overhead powerline. What should be done during planning?

  1. Ask the operator to watch for sparks
  2. Erect a warning sign and work normally
  3. Consult the network operator and maintain safe clearance Correct answer.
  4. Cover the line with a tarpaulin

Explanation

Overhead lines require consultation with the network operator and a planned safe clearance or isolation before work begins. Warning signs alone do not control the electrical hazard.

Question 16Plan and prepare work

The manufacturer requires mast ties at 6 m centres, but the building columns are 8 m apart. Which planning decision is acceptable?

  1. Use wire rope slings to columns
  2. Omit the ties between columns
  3. Add an intermediate support member Correct answer.
  4. Increase tie spacing to 8 m

Explanation

The manufacturer's tie spacing is a design limit and cannot simply be stretched to suit the building. Adding an intermediate support member lets the ties stay at the specified spacing and keeps the mast within its design assumptions.

Question 17Plan and prepare work

When planning the loading and unloading area at a hoist landing, what is the main requirement?

  1. A clear area outside the gate Correct answer.
  2. Allow workers to stand under the load
  3. Stack materials against the landing gate
  4. Store pallets on the hoist car overnight

Explanation

The landing must have a clear lay-down area outside the gate so materials can be moved without obstructing the gate or overloading the landing. Keeping the gate and access clear also supports safe evacuation and normal movement.

Question 18Plan and prepare work

Before a new hoist is first used on site, what must be completed?

  1. Competent-person inspection and testing Correct answer.
  2. A trial run by any worker
  3. A visual check by the delivery driver
  4. A toolbox talk for the crew

Explanation

Before first use, the hoist must be inspected and tested by a competent person and the results recorded, in line with the manufacturer's requirements and site procedures. This commissioning check is separate from the daily pre-start check.

Question 19Plan and prepare work

A hoist is to be tied to a building with lightweight façade panels. What should be done?

  1. Use adhesive anchors into the cladding
  2. Anchor to an engineer-verified structural member Correct answer.
  3. Anchor to the façade panel with longer bolts
  4. Tie to the nearest scaffold standard

Explanation

Mast ties must connect to structural elements that an engineer has confirmed can carry the loads; façade cladding is generally not structural. Longer bolts or adhesives into cladding do not make it suitable for tie loads.

Question 20Plan and prepare work

A hoist is planned at a site boundary next to a public footpath. Which control should be included in the plan?

  1. A secured enclosure with overhead protection Correct answer.
  2. A warning sign on the hoist only
  3. A flagger at the site gate only
  4. A temporary fence around the site office

Explanation

Where a hoist is next to a public footpath, the plan should keep the public out of the hazard area and protect them from falling objects. A secured enclosure with overhead protection achieves both separation and impact protection.

Question 21Plan and prepare work

When planning the use of a personnel and materials hoist, which document should be used first to confirm rated capacity, permitted configurations and tie requirements?

  1. The daily site diary entries
  2. The manufacturer's manual Correct answer.
  3. The site delivery docket register
  4. The project waste management plan

Explanation

The manufacturer's manual and design information set the hoist's rated capacity, permitted configurations, foundation and tie requirements. Planning must use those documented limits, and any deviation should be referred to the manufacturer or a competent engineer.

Question 22Plan and prepare work

When planning the foundation for a hoist mast, what must be confirmed about the ground beneath the base?

  1. It drains toward the nearest trench
  2. It can support the imposed loads Correct answer.
  3. It is level enough to walk across
  4. It has been compacted by the site foreman

Explanation

The foundation must be designed and assessed for the loads imposed by the mast, car, materials and wind. A competent person or geotechnical engineer should confirm the ground capacity before the base is constructed.

Question 23Plan and prepare work

Before a personnel and materials hoist is used on site, what should be verified about the operator?

  1. That they have a current first aid certificate
  2. That they have worked on site for at least five years
  3. That they hold the correct HP licence for the hoist Correct answer.
  4. That they can repair the hoist without assistance

Explanation

A personnel and materials hoist operator must hold the correct high risk work licence and be trained on the specific hoist model. Planning should verify currency and competence before the hoist is used.

Question 24Plan and prepare work

When planning the electrical installation for a hoist, which arrangement best protects against fault current and lightning?

  1. An extension lead from the site shed
  2. A lockable isolator at the site office
  3. Earthing and lightning protection Correct answer.
  4. A warning sign on the hoist gate

Explanation

Earthing and lightning protection must be installed to the manufacturer's and electrical standards to provide a low-impedance fault path. This protects operators and equipment from fault current and lightning strike.

Question 25Plan and prepare work

Which inspection arrangement should be included in the plan for a hoist used over several months?

  1. An inspection only when a fault is reported
  2. An inspection by the delivery driver on arrival
  3. An inspection by the site cleaner each Friday
  4. Periodic inspections by a competent person Correct answer.

Explanation

Hoists require pre-use checks and periodic thorough inspections by a competent person at specified intervals. The inspection schedule should be planned before use so faults are detected before they become dangerous.

Question 26Plan and prepare work

When planning how materials will be loaded into the hoist car, what is the main control for preventing movement during travel?

  1. Place the load against the car gate
  2. Restrain the load within the car Correct answer.
  3. Ask the operator to travel slowly
  4. Rely on the car overload alarm

Explanation

Loads must be restrained or contained so they cannot shift, fall or strike the car during travel. Relying on slow travel or an alarm does not control the movement of an unsecured load.

Question 27Plan and prepare work

Before planning excavation for a hoist base, what should be done about underground services?

  1. Cover the area with plywood before digging
  2. Locate and mark them before digging Correct answer.
  3. Assume they are deeper than the base
  4. Ask the crane driver to watch the excavation

Explanation

Service plans and a locator should be used to identify and mark underground services before excavation. This prevents damage to electrical, gas, water and communications services and reduces the risk of injury.

Question 28Plan and prepare work

A hoist landing is to be built on a suspended concrete slab. What must be confirmed during planning?

  1. The landing gate can be opened by hand
  2. The slab is at least 100 mm thick everywhere
  3. A structural engineer has checked the slab Correct answer.
  4. The slab has been swept and marked with paint

Explanation

A suspended slab may not be designed for the concentrated loads from a hoist landing or its operation. A structural engineer must verify the slab capacity and specify any propping or load-spreading needed.

Question 29Plan and prepare work

A hoist is planned beside an operating tower crane. Which planning control best prevents collision between the hoist car and crane loads?

  1. No-go zones and coordinated lift schedules Correct answer.
  2. Painting the hoist mast a bright colour
  3. Placing a spotter at the hoist base only
  4. Sounding the crane horn before every lift

Explanation

Physical separation, no-go zones and coordinated lift schedules prevent the hoist car and crane loads from entering each other's space. Colour, horns and a single spotter do not provide reliable collision control.

Question 30Plan and prepare work

When planning a personnel and materials hoist, what information should be displayed in the car and at each landing?

  1. The name of the site waste contractor
  2. The operator's home address and phone number
  3. The rated capacity and person limit Correct answer.
  4. The date the hoist was last painted

Explanation

The rated capacity and maximum number of persons must be displayed so users do not exceed the hoist's limits. This information should be visible in the car and at each landing before loading begins.

Question 31Plan and prepare work

When planning the emergency arrangements for a personnel and materials hoist, what must be provided for people who are stranded in the car?

  1. A set of spare keys kept in the site office
  2. A documented rescue method with trained people and equipment available Correct answer.
  3. An instruction for occupants to climb out through the car roof
  4. A procedure for the operator to lower the car to the nearest landing

Explanation

The emergency plan must set out how people can be recovered from the car or from any landing without relying on the hoist's normal power or controls. It should name the trained rescuers, the equipment they will use and how they will be contacted, and the arrangement must be tested before the hoist is used.

Question 32Plan and prepare work

The manufacturer sets a maximum operating wind speed for a hoist. The site is exposed and gusts are stronger at height than at ground level. Which planning arrangement best manages this hazard?

  1. Restrict use to early morning when winds are usually lighter
  2. Fit an anemometer at the hoist and stop operation at the manufacturer's limit Correct answer.
  3. Instruct the operator to judge wind strength by feel and stop when it seems strong
  4. Reduce the rated capacity whenever the forecast is for strong winds

Explanation

Wind speed must be measured at the hoist, because ground-level conditions and forecasts do not reflect the gusts acting on the mast and car. An anemometer with a clear stop-work trigger at the manufacturer's limit gives the operator an objective rule that can be applied and recorded.

Question 33Plan and prepare work

A hoist car will serve eight landings and several of them cannot be seen from the car. What communication arrangement should be included in the plan?

  1. A whistle code agreed with the operator before the first lift
  2. Fixed two-way voice communication from the car to every landing Correct answer.
  3. A mobile phone held by the operator and used when a landing calls
  4. Hand signals from each landing, relayed by a banksman

Explanation

Where landings are out of sight, the operator and each landing need a reliable means of two-way communication so that calls, stops and emergencies can be passed directly. A fixed system avoids dependence on personal phones and should be tested before the hoist is used and at each shift.

Question 34Plan and prepare work

A hoist has a rated capacity of 2000 kg and a maximum of 12 persons. The plan allows persons and materials to be carried together. Which loading rule should the plan state?

  1. Load to rated capacity with materials, then add persons up to the persons limit
  2. Rely on the overload device to prevent the car from being overloaded
  3. Carry persons and materials on separate trips so only one limit applies
  4. Check combined weight against rated capacity and persons against the persons limit Correct answer.

Explanation

Rated capacity is a total limit for everything in the car, so persons, materials, tools and any fitted equipment must be added together and kept at or below it. The separate maximum number of persons is also an absolute limit and is not increased because the car happens to be lightly loaded.

Question 35Conduct routine pre-operational checks and maintenance

What must the operator do before the first use of a personnel and materials hoist on each shift?

  1. Grease the wire ropes and adjust the brake clearance
  2. Dismantle the landing gates and inspect the hinges
  3. Run the hoist at full load to confirm it can lift the rated capacity
  4. Inspect the hoist and carry out function tests, recording the results Correct answer.

Explanation

The pre-operational check is a visual and functional inspection carried out before the first use of the shift. The operator inspects the structure, ropes, gates, brakes, limits and emergency stop, then records the results. Full-load testing, greasing and brake adjustment are maintenance tasks for a competent person, not routine start-up checks.

Question 36Conduct routine pre-operational checks and maintenance

How should the upper limit switch be functionally tested before the first lift of a shift?

  1. Load the car to its rated capacity and run it to the top landing
  2. Raise the empty car until the switch trips and confirm the car stops Correct answer.
  3. Bridge the switch terminals and check that the hoist continues to run
  4. Press the switch lever by hand with the power isolated and listen for a click

Explanation

The upper limit switch must be proved to stop the car by operating it under power with an empty car. The car should stop and further hoisting should be prevented until the switch is reset. Pressing the lever by hand with power off does not prove the electrical circuit, and bridging the switch defeats the safety function.

Question 37Conduct routine pre-operational checks and maintenance

Which wire rope condition requires the hoist to be withdrawn from service?

  1. A light film of lubricant on the rope surface
  2. Slight dust discolouration on the outer strands
  3. Even spacing of the strands along the rope
  4. Broken wires exceeding the manufacturer's rejection limits Correct answer.

Explanation

Wire rope rejection criteria are specified by the manufacturer and typically include broken wires in a lay length, diameter reduction, corrosion, kinks and crushed strands. Broken wires beyond those limits mean the rope has lost strength and the hoist must be withdrawn from service until the rope is replaced. Lubricant, dust and even strand spacing are normal.

Question 38Conduct routine pre-operational checks and maintenance

During the pre-operational check, how should the holding brake be tested?

  1. Raise the car, stop it, and confirm the brake holds without slipping Correct answer.
  2. Apply the brake at the bottom landing and try to push the car up by hand
  3. Measure the brake lining thickness while the hoist is running
  4. Listen for unusual noise while the car travels at full speed

Explanation

The holding brake must stop and hold the car without slippage when the power is removed. The operator raises the car, stops it and confirms the brake holds the load; any slip, delay or unusual noise is a defect. Pushing the car by hand or measuring parts while running are unsafe and do not prove brake performance.

Question 39Conduct routine pre-operational checks and maintenance

The hoist has an overload detection device. What should the operator confirm before using the hoist?

  1. That the device only operates when the car is at the top landing
  2. That the device is fitted, undamaged, and its verification is current Correct answer.
  3. That the device has been bypassed so lifts are not interrupted
  4. That the device has been removed to reduce the load on the mast

Explanation

The overload detection device is a safety device that must remain fitted and functional. The operator confirms it is undamaged, not bypassed, and that its periodic verification is current; actual load testing is done by a competent person with test weights. Removing or bypassing the device allows dangerous overloading.

Question 40Conduct routine pre-operational checks and maintenance

What is the requirement for landing gates while the hoist is in service?

  1. Gates may be left open if a warning sign is displayed
  2. Gates must be removed to allow materials to overhang
  3. Gates must be closed and locked except when loading Correct answer.
  4. Gates only need to be closed at the top landing

Explanation

Landing gates are interlocked so the hoist cannot move unless every gate is closed and locked. Gates may be opened only at the landing where the car is stopped for loading or unloading. Leaving gates open, removing them or relying on signs defeats the interlock and exposes people to falls and crush hazards.

Question 41Conduct routine pre-operational checks and maintenance

Before use, how should the emergency stop be checked?

  1. Check that it only works when the car is at the bottom
  2. Operate it and confirm the hoist stops and needs a reset Correct answer.
  3. Tape it in the off position to prevent accidental use
  4. Spray it with water to test weather resistance

Explanation

The emergency stop must immediately stop the hoist and require a deliberate manual reset before operation can continue. The operator tests it before use and confirms the reset function works. Taping or disabling the button, or assuming it only works at one landing, defeats its purpose.

Question 42Conduct routine pre-operational checks and maintenance

Which item is part of the pre-operational inspection of the hoist structure?

  1. Checking that tools are stored loose inside the car
  2. Confirming the hoist is the same colour as the building
  3. Checking that the counterweight has been painted
  4. Checking mast ties are secure and the base is not undermined Correct answer.

Explanation

Structural checks cover the mast, ties, anchor bolts, base and foundation. Mast ties must be secure and the base must be free of undermining, settlement or cracking that could affect stability. Paint colour and stored items are irrelevant to structural integrity.

Question 43Conduct routine pre-operational checks and maintenance

A maintenance task requires adjusting the brake. What isolation step is required?

  1. Press the emergency stop and begin work immediately
  2. Isolate and lock out all energy sources and verify isolation Correct answer.
  3. Leave the hoist running at slow speed while adjusting
  4. Ask a workmate to watch the control panel

Explanation

Maintenance work requires isolation and lockout of all energy sources, including electrical, hydraulic and stored gravitational energy. The isolator is locked and tagged by the person doing the work, and isolation is verified before work starts. An emergency stop or a watcher does not provide lockout protection.

Question 44Conduct routine pre-operational checks and maintenance

After completing the pre-operational inspection, what should the operator do?

  1. Record the results and report any defects before use Correct answer.
  2. File the logbook away without recording if no defects were found
  3. Record only the date and ignore minor defects
  4. Erase the previous entries so the logbook stays tidy

Explanation

The inspection record is legal evidence that the hoist was checked and that defects were reported. The operator records the results and reports any defect so it is rectified before the hoist is used. Minor defects must still be recorded, and previous entries must never be erased.

Question 45Conduct routine pre-operational checks and maintenance

During the pre-operational check, an operator finds a cracked landing gate hinge that could affect safe operation. What is the correct action?

  1. Ask a workmate to watch the gate and continue normal operation.
  2. Record the defect in the logbook and continue using the hoist at reduced load.
  3. Tag out the hoist, report the defect and stop use. Correct answer.
  4. Attempt a temporary repair with tape and continue the shift.

Explanation

A defect that could affect safe operation makes the hoist unsafe to use until it is repaired and verified. The operator should attach an out-of-service tag, report the defect and make sure no one operates the hoist. Continuing at reduced load or with a temporary repair is not an acceptable control.

Question 46Conduct routine pre-operational checks and maintenance

Which record best helps an operator confirm that the hoist's scheduled maintenance is current before starting work?

  1. The site visitor sign-in register
  2. The delivery docket for incoming materials
  3. The operator's weekly shift roster
  4. Maintenance log and inspection records Correct answer.

Explanation

Maintenance logs and inspection records show the dates and details of scheduled servicing, repairs and inspections. Checking these records is part of the routine pre-operational process, and overdue items should be reported before the hoist is used.

Question 47Conduct routine pre-operational checks and maintenance

Who should carry out a maintenance adjustment to the hoist that requires tools and technical knowledge?

  1. The person who last used the hoist
  2. A trained and authorised competent person Correct answer.
  3. The most experienced labourer on site
  4. Any operator who has watched the task before

Explanation

Maintenance beyond routine checks must be performed by a competent person who is trained and authorised for that type of hoist. Operators should not attempt adjustments outside their training, even if they have seen the task done before.

Question 48Conduct routine pre-operational checks and maintenance

When functionally testing a landing gate interlock before use, what should the operator confirm?

  1. The hoist cannot operate unless the gate is closed and interlocked. Correct answer.
  2. The gate can be opened while the platform is moving, provided a warning is called.
  3. The gate closes automatically after a timed delay.
  4. An audible alarm sounds whenever the gate is opened.

Explanation

Interlocks are safety devices that prevent hoist movement when a landing gate is not properly closed and locked. The functional test confirms that the interlock inhibits operation, rather than merely checking that an alarm or gate closer works.

Question 49Conduct routine pre-operational checks and maintenance

What should the operator check about wire rope spooling on the drum during the pre-operational inspection?

  1. The rope is spooled by hand while the hoist is running.
  2. The rope winds evenly without loose turns or crossing. Correct answer.
  3. The rope has at least three loose turns on the drum at all times.
  4. The rope is coated with fresh lubricant before every lift.

Explanation

Correct spooling ensures the rope winds evenly and avoids crossing, slack or loose turns that can damage the rope or cause erratic movement. Lubrication is carried out to the maintenance schedule, and spooling by hand while the hoist is running is dangerous.

Question 50Conduct routine pre-operational checks and maintenance

Before starting maintenance on a hoist that has been electrically isolated, what should each worker do with the isolation point?

  1. Place a warning sign on the hoist and rely on the main switch being off.
  2. Remove the fuse and leave it on a nearby bench for quick replacement.
  3. Ask the supervisor to hold the key until the task is finished.
  4. Apply a personal lock and tag and verify the hoist is de-energised. Correct answer.

Explanation

Lockout and tagout require each worker to apply a personal lock and tag so the isolation cannot be removed without their knowledge. The worker should also verify that the hoist is de-energised before starting work.
