The hands-on part of an operator trade test in which the candidate demonstrates machine control, safe lifting, signalling response and hazard awareness under an examiner's observation.
- Machine control
- Related: Practical assessment, Slewing
The operator's ability to start, steer, position, lift and stop a loadshifting machine smoothly and accurately, using the correct controls for the machine type and ground conditions.
- Safe working load (SWL)
- Related: Load chart, Rated capacity, Overload
The maximum load a machine, sling, shackle or other lifting accessory is designed and rated to lift safely under stated conditions, marked on the equipment and never exceeded.
- Load chart
- Related: Safe working load (SWL), Radius, Rated capacity
A manufacturer-supplied table or diagram showing the permitted load at each radius, boom length and configuration for a machine, which the operator must read and obey before lifting.
- Rated capacity
- Related: Load chart, Safe working load (SWL)
The load a machine or lifting accessory is approved to carry in a specified configuration, as stated by the manufacturer, and which reduces as radius or boom length increases.
- Radius
- Related: Load chart, Slewing
The horizontal distance from the machine's slewing centre or tipping point to the centre of the suspended load, a key factor that reduces permitted capacity as it increases.
- Overload
- Related: Rated capacity limiter, Load moment indicator, Safe working load (SWL)
A condition where the load or load moment exceeds the machine's rated capacity, risking structural failure or tipping, and usually prevented by a rated capacity limiter or load moment indicator.
- Rated capacity limiter (RCL)
- Related: Load moment indicator, Overload
A device that senses load and configuration and warns the operator, and may stop movement, when the machine approaches or exceeds its rated capacity.
- Load moment indicator (LMI)
- Related: Rated capacity limiter (RCL), Overload
An instrument that calculates the load moment from boom angle, length and load, displaying capacity use and giving audible and visual warnings before an overload occurs.
- Slewing
- Related: Radius, Swing brake
The rotation of a crane's upper structure or excavator's house about its vertical axis, which changes the radius and must be controlled to avoid swinging loads or striking people.
- Rigging
- Related: Slinger, Sling angle, Shackle
The selection, inspection and attachment of slings, shackles, hooks and other gear used to connect a load to a lifting machine, carried out by a competent rigger.
- Slinger
- Related: Rigging, Banksman, Hand signals
A competent worker who attaches and detaches loads to a crane hook, checks the rigging and directs the crane operator by agreed signals during the lift.
- Banksman
- Related: Slinger, Hand signals, Exclusion zone
A competent person who guides the operator of a vehicle or machine during reversing or lifting operations, using agreed signals and keeping others clear of the danger zone.
- Sling angle
- Related: Rigging, Sling
The angle between a sling leg and the horizontal or vertical load, which affects the tension in each leg and therefore the safe working load of a multi-leg sling assembly.
- Sling
- Related: Sling angle, Shackle, Rigging
A flexible lifting accessory such as a wire rope, chain or webbing strap used to connect a load to a lifting machine, marked with its working load limit and inspected before use.
- Shackle
- Related: Sling, Rigging
A U-shaped metal connector with a pin or bolt used to join slings, hooks and loads, selected by working load limit and checked for wear, distortion and correct pin seating.
- Centre of gravity
- Related: Load stability, Rigging
The point at which a load's weight is considered to act; if it is not directly below the hook, the load will tilt, so the operator must judge or mark it before lifting.
- Load stability
- Related: Centre of gravity, Outrigger
The condition in which a load remains balanced and does not shift, tilt or fall during lifting and travelling, achieved by correct slinging, centre of gravity awareness and secure stacking.
- Outrigger
- Related: Ground bearing pressure, Load stability
A retractable stabilising leg deployed on mobile cranes and some plant to widen the support base, which must be fully extended onto firm ground before lifting begins.
- Ground bearing pressure
- Related: Outrigger, Spreader mat
The load per unit area that a machine's wheels, tracks or outriggers impose on the ground, which must be within the soil's capacity, often reduced by spreader mats.
- Spreader mat
- Related: Ground bearing pressure, Outrigger
A rigid plate placed under an outrigger or track to spread the load over a larger ground area, reducing ground bearing pressure and the risk of settlement or overturning.
- Exclusion zone
- Related: Banksman, Slinger
A marked or barriered area around a lifting or plant operation that keeps unauthorised people out of the danger zone beneath and around the load and machine.
- Hand signals
- Related: Slinger, Banksman
A standardised set of arm and hand movements used by a slinger or banksman to instruct a machine operator when speech or radio communication is impractical.
- Tag line
- Related: Slewing, Load stability
A rope attached to a load and held by a person at a safe distance to control rotation and swing during lifting, without that person standing under the load.
- Rough terrain crane
- Related: Outrigger, Load chart
A mobile crane with a telescopic boom and large tyres designed to travel on uneven construction ground, which may lift on tyres only within the manufacturer's permitted limits.
- Tower crane
- Related: Slewing, Radius
A fixed or climbing crane with a vertical mast and horizontal jib used for high-rise construction, requiring careful coordination of slewing, trolley travel and hoisting.
- Excavator
- Related: Swing brake, Exclusion zone
A tracked or wheeled machine with a boom, dipper arm and bucket used for digging, trenching and loading, which must be operated clear of buried services and people.
- Wheel loader
- Related: Machine control, Exclusion zone
A rubber-tyred machine with a front-mounted bucket used to scoop, carry and load loose material, requiring the operator to keep the bucket low and watch for pedestrians.
- Forklift truck
- Related: Safe working load (SWL), Load stability
A powered truck with a mast and forks for lifting and stacking palletised loads, which must be operated with the load low and the mast tilted back while travelling.
- Swing brake
- Related: Slewing, Excavator
A brake that stops and holds the rotation of an excavator's upper structure or a crane's slewing motion, essential for controlling a swinging load on uneven ground.
- Daily inspection
- Related: Thorough examination, Machine control
A pre-use check of a loadshifting machine covering fluids, tyres or tracks, brakes, horns, alarms, lifting gear and safety devices, recorded before the machine is put to work.
- Thorough examination
- Related: Daily inspection, Competent person
A detailed statutory examination of lifting appliances and gear by a competent examiner at specified intervals, with a report issued before the equipment may continue in use.
- Permit to work
- Related: Lifting plan, Exclusion zone
A formal written authorisation for a specific high-risk task such as a critical lift, setting out the precautions, personnel and time limits under which the work may proceed.
- Lifting plan
- Related: Permit to work, Rigging
A documented method for a lifting operation that identifies the load, crane, rigging, ground conditions, personnel, sequence and hazards, prepared and approved before work starts.
