Bridge crane structure

Today, bridge cranes are very popular in various industries. Its use has increased the efficiency of mechanical work, reduced the workload of workers, and made an important contribution to accelerating industrial production. Before you can work on a bridge crane, you need to understand its structure. Let's take a look at it now.
    
The bridge crane is generally composed of a bridge frame, a trolley equipped with a lifting mechanism, a trolley running machine, a control room, a trolley conductive device, and a crane main power conduction device.
 
The bridge frame is the basic component of the bridge crane, and is mainly composed of a main beam, an end beam, a walking platform and the like. The walking platform is on the outside of the main beam, which is used for installing and repairing the running mechanism of the cart and placing some electrical equipment and the conductive sliding line of the trolley. There are safety railings on the outside of the two main beams, and doors are installed at both ends, and there are safety switches on the doors. A cart running mechanism is mounted on the side of the carriage on the side of the cab. The other side of the walkway is equipped with power supply means for all electrical equipment on the cart. A trolley movement track is placed above the main beam for the trolley to run.
  
The running mechanism of the cart consists of a motor, a brake, a drive shaft, a coupling, and a wheel.
