This is a 1-day course with demonstrations on Aerial Lift Safety and Rigging scenarios. We will cover Aerial Lift set-up (pre-trip inspection, stabilizer leveling, full-body harness inspection, safety lanyard inspection, operator anchor point, proper unfolding and folding, platform controls, bucket positioning, operator positioning). In the Rigging portion; forces at the block, using a dynamometer to show the forces generated; difference between an arborist block and rescue pulley; difference in the different rope constructions with advantages and limitations of each; tying a cow hitch and timber hitch for anchoring in the tree; cutting a notch for directional control; Port-a-wrap use near the base of the tree; we will show the different ringed product tools, a knotless rigging system and using a re-direct block to help spread the forces in the canopy and reduce the chances of a cut limb swinging back towards the operator.
