High Risk Work Licence - Derrick Crane (CD) key terms

A legal obligation for employers, workers and others to take reasonable steps to protect the health and safety of everyone affected by their work activities, so far as is reasonably practicable.

The overarching legal responsibility placed on a person conducting a business or undertaking to ensure, so far as is reasonably practicable, the health and safety of workers and others affected by the business.

A standard for deciding what safety measures are required, weighing the likelihood and severity of harm against the cost, effort and availability of ways to eliminate or reduce the risk.

The legal entity that runs a business or undertaking and holds the primary work health and safety duties, including providing a safe work environment, safe systems of work and adequate information, training and supervision.

A formal authorisation issued by a regulator that allows a person to perform specified high-risk work, such as operating a derrick crane, after demonstrating competence through assessment.

The category shown on a high risk work licence that specifies which types of equipment or tasks the holder is permitted to perform, such as derrick crane operation.

A formal evaluation of a person's knowledge and practical skills against a national standard, required to obtain or renew a high risk work licence.

Any situation, condition or thing that has the potential to cause injury, illness or damage to property or the environment.

The likelihood that a hazard will cause harm, together with the severity of the harm that could result.

A structured process of identifying hazards, evaluating the likelihood and consequences of harm, and deciding on control measures to eliminate or minimise the risk.

A ranked list of risk control measures, from most to least effective: eliminate the hazard, substitute, isolate, engineer, administrate, and finally use personal protective equipment.

An action, device or procedure put in place to eliminate a hazard or reduce the risk it poses to an acceptable level.

A crane with a mast, boom and load line that is held upright by guy ropes or stays anchored to the ground or a structure, rather than by a heavy base.

The vertical structural member of a derrick crane that supports the boom and transmits loads to the guys and foundation.

The inclined structural member of a derrick crane that projects outward to support the load line and sheaves at its tip.

A tensioned rope or cable that stabilises the mast or boom of a derrick crane by connecting it to ground anchors or a structure.

A fixed point or structure to which guy ropes or stays are attached, designed to withstand the loads imposed by the crane.

The prepared ground or structural base that supports a derrick crane and distributes its loads, including the weight of the crane, load and forces from the guys.

Additional weight added to a crane or its base to improve stability and counteract overturning forces during lifting.

The ability of a crane to resist overturning or tipping under the combined effects of its own weight, the load and external forces such as wind.

The point through which the total weight of an object acts; for a crane and load system, its position affects the tendency to tip.

The turning effect produced by a load, calculated as the load weight multiplied by its horizontal distance from the crane's tipping point or slew centre.

A document supplied with a crane that specifies the maximum safe working load for various radii, boom lengths and configurations under defined conditions.

The maximum load that a crane or lifting gear is permitted to lift under specified conditions, as determined by the manufacturer or a competent person.

The horizontal distance from the crane's centre of rotation or tipping point to the centre of the load being lifted.

The maximum mass that a particular item of lifting gear, such as a sling or shackle, is designed to support in a specified configuration.

A flexible lifting component, such as a wire rope, chain or synthetic webbing, used to connect a load to the crane hook.

The process of preparing and connecting lifting equipment, including slings, shackles and ropes, to safely lift and control a load.

A licensed worker who directs crane operators using signals and attaches or detaches loads using slings and other lifting gear.

A worker who prepares and assembles lifting equipment and loads, and may also direct the crane operator during lifts.

The exchange of information between the crane operator, dogger, rigger and other workers to ensure lifts are performed safely and as planned.

A hand, whistle, radio or light communication used to direct the crane operator's actions during a lift.

Cooperative effort among the crane operator, dogger, rigger and other personnel to plan and execute lifts safely, with clear roles and responsibilities.

A check carried out before each use of a crane to identify defects, damage or unsafe conditions that could affect safe operation.

Planned and corrective activities, such as lubrication, adjustment and repair, carried out to keep a crane and its equipment in safe working condition.

A systematic examination of a crane and its components to verify they meet required standards and are free from defects.

A documented set of actions to be followed in response to an incident, such as a fire, power failure, load drop or structural failure, to protect people and property.

The immediate actions taken after an accident or near miss, including first aid, securing the area, notifying authorities and preserving evidence.

The safe sequence of actions to stop crane operations and secure the equipment, such as lowering loads, applying brakes and isolating power.
