32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- HP licence scope
- An HP licence authorises operation of personnel and materials hoists designed to carry people and materials; it does not authorise materials-only hoists to carry passengers.
- Rated load
- The maximum load a hoist is designed to carry in a specified configuration, including persons, materials, tools and attachments but excluding the car's dead load.
- Load chart
- A document or plate that states the rated load for each hoist configuration, such as number of persons, landing heights and tie arrangement; it must be followed.
- Safe work method statement
- A document that identifies high-risk work hazards, controls, sequence and emergency arrangements for erection, operation and dismantling of the hoist.
- Exclusion zone
- A barricaded area beneath and around the hoist, landings and erection zone where people are not permitted during operation or dismantling.
- Hoist logbook
- A record kept with the hoist for daily inspections, maintenance, defects, repairs, tests and operating hours; it supports traceability and safe-use decisions.
- Pre-start inspection
- Checks completed before first use each day, covering base, mast, ties, outriggers, gates, interlocks, ropes, brakes, limit switches and controls.
- Final limit switch
- A switch that stops the car if the normal upper limit fails; it must operate independently and prevent over-travel beyond the safe zone.
- Overspeed safety device
- A device that detects excessive descent speed and arrests the car, protecting against free fall if the rope or brake fails.
- Wire rope discard criteria
- Conditions such as broken wires, kinks, bird-caging, corrosion, crushed strands or damaged end fittings that require the rope to be removed from service.
- Brake holding test
- A test confirming the hoist brake holds the rated load without uncontrolled descent; it is done at specified intervals and after repair.
- Tag out
- A lockout/tagout process that isolates energy, attaches a warning tag and prevents operation until a competent person repairs and clears the defect.
- Base bearing capacity
- The ability of the ground or supporting structure to carry the hoist's dead load, rated load and dynamic forces without settlement or failure.
- Mast verticality
- The mast's alignment checked in two directions and kept within the manufacturer's tolerance; excessive tilt increases load and can prevent safe operation.
- Tie-in
- A structural connection between the hoist mast and a building or structure at specified intervals, designed to resist hoist loads and wind.
- Outrigger
- An extendable support leg that widens the hoist base and must be fully extended, pinned and locked before operation.
- Landing gate interlock
- A device that prevents car movement unless the landing gate is closed and latched, and prevents opening the gate unless the car is at the landing.
- Deadman control
- A control that requires continuous pressure by the operator; releasing it stops car movement, reducing risk if the operator loses control.
- Rated load distribution
- Placing personnel and materials evenly within the car and securing them so the load remains within the rated load and does not shift.
- Communication signal
- An agreed method such as radio, bell, hand signal or phone used between operator and landings; unclear signals require stopping.
- Wind stop limit
- The maximum wind speed specified by the manufacturer for safe operation; work stops when it is reached or exceeded.
- Emergency lowering
- A manual or auxiliary procedure to lower the car safely when power fails or controls malfunction, performed by trained persons following the manufacturer's instructions.
- Materials-only hoist
- A hoist designed only for goods; it must not carry people even if the car appears suitable, unless it is designed and rated for personnel.
- Parking procedure
- Lower the car to the designated landing, apply the brake, isolate power, lock controls and secure gates before leaving the hoist.
- Isolation
- Switching off and locking the energy supply, and verifying no movement is possible, before maintenance or shutdown.
- Dismantling sequence
- The planned reverse of erection, removing ties, mast sections and base under supervision with an exclusion zone and fall protection.
- Out-of-service storage
- Protecting ropes, sheaves, electrical parts and manuals from damage, moisture and unauthorised use while the hoist is not operating.
- Return to service
- After repair or dismantling, the hoist is inspected, tested and recorded by a competent person before it is used again.
- Fall arrest system
- Personal equipment such as a harness and lanyard that limits fall distance during erection or maintenance where guardrails cannot be provided.
- Rescue at height
- A planned procedure and equipment to recover a person trapped or suspended on the hoist without exposing rescuers to uncontrolled falls.
- Hierarchy of control
- The order of risk controls: eliminate, substitute, engineer, administrative and PPE, with higher-level controls preferred.
- Notifiable incident
- A serious incident such as death, serious injury or dangerous occurrence that must be reported to the regulator and recorded.
