Operate a tracked dozer

DESCRIPTION

Unit Standard (SAQA Reg. No 262729)

A dozer short for bulldozer is a continuous tracked tractor with a substantial wide metal plate (blade) that is mounted to the front of the tractor. Dozers are large and powerful tracked machinery and the tracks provide them with ground holding capability and mobility in all kinds of terrains. The torque divider is designed to transform the engine power in order to enhance the dragging capacity. Commonly a dozer is used to move significant magnitude of soil, sand, debris, obstacles, clear roads and bushes.

Operators who are not adequately trained in tracked dozer operations are at great risk of injury because of their lack of understanding in the principles of operations that allow tracked dozers to move sand, soil, debris and other material.

Successful candidates credited with this unit standard are able to:

  • Demonstrating knowledge of the functions of a tracked dozer
  • Planning for work activities and prepare work area
  • Starting and shutting down tracked dozer
  • Operating tracked dozer
  • Transporting tracked dozer to and from site
