Outrigger support pad performance, it is a kind of ultra-high molecular weight polyethylene engineering plastic that is constantly bent. The outrigger support pad is mainly used to pad under the legs of construction machinery to play a supporting role. Outrigger pads have higher strength and stiffness, which can reduce the amount of deformation of the pad body when under stress, and provide a more stable supporting force for construction machinery. Greatly save the use cost and improve the work quality. The leg pad is composed of a plate-shaped pad board body and a hand rope. To facilitate carrying and arrangement.
