Currently, the coil type induction-motor-driven hoist adjustable rope, change, change thecontainer maintenace work suspension clamp, mostly use rope clamps, auxiliary winch used asauxiliary equipment. This method is long and large amounts of production, low efficiency anddangerous effects, mine production, so it is necessary to improve methods, improve efficiency.This paper designs a set of wire coil type induction-motor-driven hoist devices. This device ismainly composed of spindle unit, coupling and reducer, brake, the main components of thedesign of hoist device, the spindle speed reducer and brake system is special product, supportingthe motor can be flexibly choice. This machine can be used, the maintenance and inspection etcsystem and improve the efficiency of the machine. The design of the coil type induction-motordrivenhoist is characteristic of simple structure, evenly, smooth operation, small friction, lowcost, high efficiency, easy maintenance etc, and has a strong adaptability.The designing mainly put particular emphasis on silo hoisting system , includes: to choose the lifting hold、to choose the hoist steel wire rope、 to choose the hoister、 to choose the relatives of the hoister、 to choose the dynamics of the hoister、to choose the electromotor.
