What are the components of Double Girder Bridge Crane?

Double girder bridge crane is a common heavy lifting equipment, mainly used in industrial production and warehousing and transportation. Its basic working principle is to operate on the track between two main beams through electric hoists or other lifting equipment to carry out lifting operations. Double girder bridge cranes are usually composed of multiple key components, each of which has different functions to enhance the safety and work efficiency of the crane.

1. Bridge

The bridge is the main load-bearing structure of the double girder bridge crane, mainly composed of two main beams and cross beams. It transfers all loads to the support system, carrying the deadweight of the crane and the hoisting load. The main beam is the main structure of the crane, welded from steel, and carries the overall weight and load of the crane. It is a box-type structure that can withstand large bending moments and shear forces. Its cross beam connects the two main beams and gives the bridge lateral stability.

2. Lifting mechanism

The lifting mechanism is the core component used to lift heavy objects, responsible for the vertical lifting and lowering action of the crane. It consists of electric hoists, electric winches and other equipment. The electric hoist is the most common lifting device. It drives the drum through the motor and winds up the wire rope to lift and lower the load. The drum is used to wind the wire rope, and the wire rope is used to lift the load. When the lifting mechanism stops working, the brake device will keep it stable to prevent the load from sliding down.

3. Electrical control system

The electrical control system is used to coordinate the work of each part and enhance the accuracy and safety of crane operation. It includes an operating panel, a control circuit, sensors and various safety devices. The operator can control the various functions of the crane through the control panel, and the sensor can monitor the status of the crane to prevent overloading, limit exceeding or other dangerous situations.

Each component of the double girder bridge crane plays a very important role in the work of the crane, allowing us to complete the work more efficiently.
