Learning Outcomes

This unit of competency describes the skills and knowledge required to use cranes to access and dismantle trees in close proximity to assets and in difficult or hazardous circumstances. The unit applies to individuals who work in arboriculture under broad supervision and take responsibility for their own work. They use discretion and judgement in the selection, allocation and use of available resources and for solving problems The arboriculture industry requires that all tree work with a crane is undertaken according to preferred industry practices (as outlined in the Companion Volume). Legislation, regulations and by-laws relating to the treatment and removal of trees, and the use of cranes, apply in some states and territories.
