Vertical lifting transport machinery is an important component of the tie in with the derrick, mast, pulley blocks, and auxiliary equipment, used to enhance the materials, installation of equipment operations, from human or mechanical power-driven drum, winding traction rope to complete the installation work. Vertical, horizontal or inclined simple tractor Lifting heavy objects. Two types of the hoist are manual and electric two kinds. and Now to the main electric winch. The design of the 5-ton electric hoist motor contions electromotor 、coupling、arrester、retarder、drum、boom sheave 、a system of pulleys set、hook, etc.. This design of hoist is start from the wire rope, and next then turn on the winch drum, drum spindle, motor, gear reducer, speed reducer shaft, brakes, couplings and pulley drum machine-oriented design and selection. On drum, drum shaft, drum hub, most major reducer design, the design are focus introduced, and the rest is just a little something for analysis. The design of the drum machine because of its simple structure, handling the installation of a flexible, convenient operation, simple maintenance, and operating environment features such as adaptability, can be applied to lifting metallurgical, construction, operations and other water conservancy, but the design mainly applied to the drum machine for 5-ton overhead crane hoisting mechanism. Heavy winch upgrade is one of the main functions of the design of various types of winches are based on based on this request. keywords: hoist,drum,drum shaft
