Outrigger pad composition: The outrigger pad consists of a plate-shaped pad body and a hand rope. The plate-shaped backing plate body is made of UHMW/HDPE polymer composite material. The four-corner support of the PE polymer composite material backing plate 60mm bears a pressure of more than 15-18 tons/cm, which can be used normally in harsh environments, and can be bent without breaking when overloaded. The hand rope is made of nylon material, and the end of the hand rope is embedded in the body of the backing plate for easy carrying and arrangement. The outrigger pads pressed by ultra-high molecular polyethylene materials have a stronger pressure bearing capacity, which can reach 10-300 tons.
