With the progress of the development of society and the times, competition between each industry more strongly, so manufacturers are continually improving and updating production techniques to improve the productivity of equipment. Cranes in the increasingly important role in the production, and production requirements are increasingly high requirements for crane, crane's performance is also more comprehensive. Today's automated production is inseparable from the crane.
The design is mainly for bridge crane cart mechanism and institutional design of hoisting mechanism, but also motor, reducer, drum, calculated selection of wire rope, hook and after a series of calculations, crane load capacity can be achieved 50-10T And car running gear and hoisting mechanism is simple in structure, easy, easy maintenance.
Keywords: Bridge cranes; running institutions; lifting mechanisms design
