Working Principle of Double Girder Overhead Crane
2025-04-11
Double Girder Overhead Crane is a kind of heavy equipment widely used in industry, mainly for material handling and warehouse management. Its working principle involves a number of systems working together, including the structure system, drive system, control system and so on.
1、Structure system
The main structure of a double girder overhead crane consists of two parallel main girders, which support the weight of the whole crane as well as the materials being lifted. These main girders are connected to the bottom beams and support legs to form a sturdy bridge structure. This design allows the crane to run on a fixed track to realize the horizontal movement of materials in the plant.
2、Drive system
The drive system mainly consists of electric motor, reducer, brake and wheels. The electric motor provides power, reduces the speed and increases the torque through the reducer, and drives the wheels to make the crane move. The brake is used to control the speed and position of the crane.
3、Control system
The control system includes the operation room, joystick, sensors and electrical system. There are control boards and various meters in the operation room, the operator sends commands through the joystick, and the sensors monitor the status of the crane and feed back to the operation room. The electrical system controls the operation of the motor according to the commands and feedback information to realize various actions of the crane.
4、Operating Principle
The working principle of double girder overhead crane can be summarized in the following steps:
1. the operator sends commands through the operation room, and the commands are transmitted to the electric motor through the electrical system. 2. the electric motor receives the commands and controls them.
2. the motor receives the command and starts working, generating power. 3.
3. The power is transmitted to the wheels through a speed reducer that reduces the speed and increases the torque. 4.
4. The wheels rotate and drive the crane to move along the track. 5.
5. At the same time, the operator can control the crane's hook lifting and rotating through the joystick.
6. Sensors monitor the status of the crane to ensure safe operation and feedback the information to the operation room.
In conclusion, double girder overhead travelling crane realizes material handling and storage management through the cooperative work of structure system, drive system and control system. Its efficient and flexible working mode makes double girder overhead travelling crane become an indispensable and important equipment for modern industry.
