Drum generally consists of three parts, namely, tube shell flange (round sticks) and the support ring. Drum drum shell is the most basic and the most vulnerable ponents is the drum part of the main bearing. The thickness of the role of support ring is to increase the stability of drum. Cylinder shell and support material for the steel wheel. The operation of the mine hoist Practice has proved that the wood lining on the cylinder shell can play a role in the protection, so the design of the shell in the outer tube equipped with a wood , wood lining to protect the shell of the cylinder only in the shape of the shell tube parison rules, no larger deformation, and the production of wood of suitable timber liner (now monly used oak, Manchurian ash or elm, such as production), so that wood lining with the cylinder shell can be uniform throughout the case of close contact to be effective, the hoist is installed, the requirements of the cylinder shell shape of the cylinder is more rules, wood contrast with the abovementioned timber production, in accordance with the provisions of car rope groove . The installation of wood lining, the lining should be trees lining the length of the direction of the drum shell with uniform tight contact with wood liner lining the gap betw
