32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- LOLER
- Lifting Operations and Lifting Equipment Regulations 1998; require lifting operations to be planned, supervised, and carried out by competent persons, and equipment to be examined at statutory intervals.
- PUWER
- Provision and Use of Work Equipment Regulations 1998; require work equipment to be suitable, maintained, and inspected, and users to be trained.
- Competent person
- A person with sufficient theoretical and practical knowledge and experience to perform the required duties safely, such as planning lifts or examining equipment.
- RIDDOR
- Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013; require reporting of dangerous occurrences including lifting equipment failure.
- Appointed person
- The person with overall responsibility for planning a lifting operation, including selecting equipment and personnel and preparing the lift plan.
- Crane supervisor
- The person who implements the lift plan on site, directs the lifting team, and has authority to stop the operation if conditions change or become unsafe.
- Slinger/signaller
- The person responsible for attaching and detaching loads, guiding the load, and communicating signals to the crane operator.
- Crane operator
- The person responsible for operating the crane safely in accordance with the lift plan and signals received, and for stopping if a signal is unclear or unsafe.
- Exclusion zone
- An area beneath and around the load path from which persons are excluded to prevent injury from falling loads or moving equipment.
- Risk assessment
- A systematic process of identifying hazards, evaluating risks, and implementing control measures to reduce risk to an acceptable level.
- PPE
- Personal protective equipment; includes hard hats, high-visibility clothing, and safety footwear required for personnel involved in lifting operations.
- Overhead power lines
- Electrical hazards that must be identified and either isolated or kept at a safe distance from lifting equipment to prevent electrocution.
- Safe working load
- The maximum load that a sling or lifting accessory may lift under specified conditions; it must never be exceeded.
- Webbing sling inspection
- Check for cuts, tears, abrasion, chemical damage, and damaged labels; remove from service if any defect is found.
- Chain sling inspection
- Check for stretched links, cracks, gouges, and wear; wear exceeding 10% of original link diameter is grounds for rejection.
- Wire rope sling inspection
- Check for broken wires, corrosion, kinks, and bird-caging; the number of broken wires in a given length determines rejection.
- Shackle
- A rated connector marked with its SWL; screw pin shackles must be fully tightened and moused if there is a risk of the pin unscrewing.
- Sling angle effect
- As the angle between sling legs and the horizontal decreases, the tension in each leg increases for the same load, reducing effective capacity.
- Centre of gravity
- The point at which the load's weight is considered to act; it must be directly below the crane hook to prevent swinging or tilting.
- Tag line
- A rope attached to a load to control its rotation and movement during lifting, especially for long or awkward loads.
- Basket hitch
- A sling configuration where the sling passes under the load and both ends attach to the hook; SWL is typically twice that of a single leg if legs are vertical.
- Choker hitch
- A sling configuration where the sling passes around the load and through itself; SWL is reduced, often to 80% of the single-leg capacity.
- Emergency stop signal
- Given by extending one arm horizontally and moving it rapidly side to side at shoulder height; anyone may give this signal.
- Raise load signal
- Given by pointing the forearm upwards with the hand open and moving it in a small circle.
- Lower load signal
- Given by pointing the forearm downwards with the hand open and moving it in a small circle.
- Dog everything signal
- Given by holding one arm horizontally and moving the other hand across it in a cutting motion; means stop.
- Radio communication
- Must use clear, standard phrases; the operator must repeat back critical instructions to confirm understanding.
- Lifting plan
- A document prepared by the appointed person that includes load weight, rigging, crane position, load path, personnel roles, and contingency measures.
- Load weight verification
- The load weight must be confirmed from documentation or calculation; if unknown, it must be determined by a competent person before lifting.
- Crane capacity check
- The crane's capacity must be checked against the load chart for the specific radius, boom length, and configuration; the load must never exceed rated capacity.
- Site coordination
- Organising the site to provide safe access, adequate space, and exclusion zones, and ensuring coordination between all personnel involved in the lift.
- Pre-lift briefing
- A meeting before the lift to communicate the lift plan, roles, and responsibilities to all involved personnel.
