Unit of competency details

Unit Descriptor 

This unit specifies the outcomes required to operate a slewing strut-boom crane with its boom pivoted at the base of a mast which is either guyed (guy-derrick) or held by backstays (stiff-legged derrick) and which is capable of luffing under load for licensing purposes.

Application of the Unit 

This unit requires the operator to plan the work, conduct routine checks, transfer loads, and shut down and secure the derrick crane.

This unit is based on the requirements of the National Standard for Licensing Persons Performing High Risk Work.

This unit in its current form meets state and territory licensing requirements. Any alteration will result in a unit which is not acceptable to regulators for the purpose of licensing.
