The Design of the Hoisting Mechanism of Bridge Crane
Abstract
The crane is wildly used in industrial and mining enterprises, port ,station warehouse,building site,sea development, space navigation and so on.,it is certain that the crane do a efficient job in the aspects of the land.the sea,the sky,,the civil use, and the military use.
With development,the crane and transport machines have become the base of the reasonable parts in mass product and mechanical line procdcut areas and now it is one of the important symbols of modern manufacture..The crane will play an important part in development of the four modernizations and promot on mechanical level,produce effieincy in every industry departments.
This carne is a kind of 250/50/10t bridge carnes for hydropower station, builded in the workshop of Fengman hydropower station for the extend project. It is used to install, examine and repair of sets of water-turbine generator. This paper focuses on design of hoisting mechanism of the carne, including the main and assistant hoisting mechanism with electromotors, reducers, brake staffs, drum devices and pulley gears. The carne is required to be stables, high accuracy, safety, reliability and advanced technology.
Key words: carne, Bridge Crane, design of the hoisting mechanism
