Unit Descriptor

Unit descriptor 

This unit specifies the outcomes required to operate a self-erecting tower crane for licensing purposes, and covers the operation of a crane where the tower structure and boom/jib elements are not disassembled into component sections, which can be transported between sites as a complete unit, and where the erection and dismantling processes are an inherent part of the crane's function.

Application of the Unit

Application of the unit 

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

Evidence Guide

EVIDENCE GUIDE 

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Successful assessment of this unit meets the competency requirement of the National Standard for licensing Persons Performing High Risk Work.

State/Territory OHS regulators have mandated the use of Assessment Instruments and Instructions for Assessment for this unit which have been endorsed by the national body responsible for OHS matters.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

A person who demonstrates competency in this unit must be able to provide evidence of the ability to:

  • comply with OHS licensing legislation
  • effectively communicate and work safely with others in the work area
  • assess risk and management procedures (particular awareness of the risks associated with overhead powerlines/electrical cables, wind and crane stability)
  • operate a self-erecting tower crane for the lifting and moving of loads to the safe working rated capacity in conjunction with other appropriate personnel
  • apply standard mathematical procedures for estimation of loads.

Context of and specific resources for assessment 

  • Assessment of the safe and effective application of knowledge and skill to workplace tasks (performance) must be undertaken using the endorsed Assessment Instrument
  • Assessment of performance must be undertaken either in the workplace or in a realistically simulated workplace setting
  • Assessors must ensure that the assessment in the workplace is organised to ensure that all the required equipment and materials and a suitable working area is made available to suit the assessment and the workplace
  • Assessment must occur under standard and authorised work practices, safety requirements and environmental constraints
  • Assessment is to comply with relevant appropriate standard requirements
  • Applicants must have access to:
  • personal protective equipment (PPE) for the purpose of the Performance Assessment.
  • appropriate self-erecting tower crane and associated equipment in safe condition
  • suitable loads as specified by the endorsed assessment instrument
  • communication equipment (eg. two-way radios, whistles, etc)
  • other appropriate personnel to sling and direct the loads.

Method of assessment 

Assessment must be conducted using the endorsed Assessment Instruments. These Instruments provide advice on their application.

The use of 'simulators'  in the assessment of this unit of competency is not acceptable .

Assessment may be in conjunction with the assessment of other units of competency.

Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge.

Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstances, but is able to be transferred to other circumstances.

Guidance information for assessment 

Further information about endorsed assessment instruments may be obtained from state/territory OHS regulators.
