Introduction about Bridge Building Crane

 
Bridge building crane is a kind of elevator machine operated on the overhead railway, which is also called overhead crane.

1. Bridge building crane move on the two sides tracks in a longitudinal direction while its crab is running crosswise. We can see that the shape of its working scope looks like a rectangle. Thus our overhead crane can make full use of space under the bridge to convey materials and it won’t be hindered by ground equipments.

2. Bridge building crane can make the weight hanging on hook or other load handling devices lift vertically or move horizontally. Hoisting machine, big and small vehicles can match with each other perfectly, so that lifting and transporting weight in a certain cube space can be realized. Bridge crane, gantry crane, loading bridge, overhead crane for metallurgic plants, cable crane and etc. are kindred.

3. Bridge building cranes are widely applied in indoor and outdoor warehouse, mill workshop, wharf and open-air storage yard and so on.

4. Bridge building cranes can be classified into ordinary overhead crane, simple girder bridge crane and metallurgy crane.

5. Its hoisting mechanism contains electromotor, brake, reducer, winding drum and pulley block. On the help of reducer, electromotor can mobilize wind drum to rotate. After that, steel wire ropes will roll on the winding drum or lay down from it. Finally, heavy materials can go up and down.
