A coal mine is a vertical well. Before entering it, the fully mechanized support is dismantled into parts, and sent into the well through the cage, then they are transported by a flat car to the fully mechanized coal face. Underground space is little, the large lifting equipment can not be used, before the top beam and other large parts are removed fully by workers manually by chain hoist installation and dismantling. Therefore, the hydraulic support disassembling hanger of fully mechanized working face was developed.Then the labor intensity for workers is reduced and the speed of disassembling is improved, work efficiency is improved, and the security of workers is guaranteed.
