Treepartner Training Courses
A04
Tree Dismantling Operations (Rigging)
Pre-Course Requirements:
To attend this course trainees must already hold a qualification in Chainsaw from a Rope and Harness.
This course is designed to follow on from A02 and provides an overview and structure to a high-risk activity in the tree care industry. Aerial and ground worker trainees will learn new practical skills and improve their competence levels. They will have the opportunity to use the LineGrip Linescale 3 load cell which provides feedback to support end user estimations of section weight and anticipated forces in a range of rigging scenarios.
