Arboricultural Equipment: Rigging Equipment Slings, block and tackle, carabiners, whoopie slings, friction drums and pullies are used in various combinations to making technicial rigs to safely manage and lower tree limbs and trunks to the ground. We use heavy duty ropes to control the descent of limbs and tree trunk safely to the ground. Dismantling urban trees safely is a science and a specialize tree crew must be familar with various advanced technical rigging to safely remove some trees and palms. Friction devices are an unique and essential piece of arborist equipment which has a bollard and a ratcheting system of mechanical advantage which can raise and lower tree limbs and trunks; giving us exceptional control over large tree limbs which are being removed. |
