Unit Descriptor

Unit Descriptor 

This unit covers the competency required to assess equipment and vehicles requiring recovery and to employ suitable winching techniques and procedures to extricate casualties utilising specialist recovery vehicles equipped with motorised winching equipment.

Application of the Unit

Application of the Unit 

This unit applies to the operation of winching equipment capable of extracting a range of vehicles and equipment. Winching may be necessary to extract vehicles and equipment which have become bogged or broken down and due to terrain or environmental factors, cannot be extracted by other means.

Typically, winching operations are conducted by individuals acting independently or in charge of a small team, isolated from assistance or supervision.

Evidence Guide


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

Assessment must confirm the ability to:

  • conduct winching operations on ground which is soft enough to simulate the conditions encountered when winching bogged vehicles
  • conduct a winching operation to extricate a light and a medium/heavy rigid vehicle
  • utilise motorised winches, winch ropes and associated fittings.

Consistency in performance 

Competency should be demonstrated over time using a variety of equipment casualties and situations which the candidate is likely to encounter within the workplace.

Context of and specific resources for assessment 

Context of assessment 

Competency should be assessed in areas of difficult terrain incorporating undulating ground.

Specific resources for assessment 

Access is required to:

  • recovery vehicles and winching equipment
  • actual or simulated equipment casualties
  • specific workplace operating procedures and publications.
