Description
This unit of competency describes the skills and knowledge required to select, check and install rigging systems to support aerial tree work for the controlled descent of loads to drop zone. This unit does not cover crane operations.The unit applies to individuals working in a broad range of arboriculture contexts who undertake defined routine activities under supervision. They exercise limited autonomy within established and well known parameters, providing solutions to a limited range of predictable problems.The arboriculture industry requires that all ground-based tree rigging work 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 apply in some states and territories.
