We are offering electric hoist etc. 1.1 usage of productcd1, md1, hcd1, hmd1 wire electric hoist is a widely used in enterprises which need lifting equipment for lifting heavy objects. Such as mining companies and railways, docks, warehouses. as it has small shape and easy to matins, and could be installed on single-girder overhead crane and motor-driven single beam suspending crane in straight or curvely shapes, as well as to use with electric wire rope hoists gantry cranes for lifting1.2 safety and working conditions the products working environment temperature is between -20 c to +40 c, and relative humidity of air should within 85%, and within 1000 meters altitude. flammable, explosive and corrosive gases or dust must not be contained. it is prohibited to manned. It is not allowed to lift molten metal and hot solid metal (if the capacity is less than 10 tons, we can advance the design according related laws)operation of the bridge should be strictly according to gb6067-1985 "crane safety regulations" if it is used in open space, it should be protected and be set free from moisture. the user should consult with the manufacturer if it is used beyond the mentioned conditions and requirements above. the products working level should be according b/t9008.1-2004 "wire rope hoist - part 1: types and basic parameters and technical conditions" in the regulations. 2.2 main structure and working principle of cd1, md1, wire rope electric hoist cd1, md1 rope electric hoist is made up by 3 parts: hoisting mechanism, operating mechanism and electrical control devices. md1, hmd1 electric wire rope hoist is based on cd1, which changes hoisting mechanism to dual stator-winding induction generator. It has 2 types speeds: normal speed and slow speed. It is different with cd1 rope electric hoist merely in hoisting mechanism and electrical control devices. 2.2.1hoisting mechanismcd1, md1 rope electric hoists hoisting mechanism is as following:the hoisting machine pass elastic coupling and riches reducers gear, then drive to hollow axis, thus to drive roll unit as to make the rope around the drum drive hook unit up or down. lifting height h = 6m, when crane capacity
