3、eed to improve the production technology, improve production efficiency, manufacturing industry to bridge cranes increasingly high demand, properties are increasingly full. The design of the crane trolleys, lifting trolley along the trolley track is moving horizontally, and does lifting hook campaig

4、n. The scope of work is moving beyond its rectangular lots of space, and is generally in the form of workshops suit. Through the overhead crane trolleys in operation and effect of part or part of the overall design, and the motor, Coupling, bumpers, brakes, the calculation of rope to use running and

5、 lifting the reducer design and components are calculated and structural design, completion of the bridge crane trolleys in two important institutions mechanical parts of the design. Through this series of designs to meet up to 50 weight / 10T requirements, Trolley and running and lifting mechanism is simple, easily reassembled and easier to maintain.
