Double-girder crane is a common lifting equipment, mainly composed of two main girders, end beams, lifting trolley and electrical system.
I. Structural characteristics
Main girder:
Adopting box structure, it has high strength and rigidity and can bear large loads.
End beam:
Connecting two main girders to form an integral frame.
Wheel sets are usually installed on the end beam to enable the crane to run on the track.
Lifting trolley:
Composed of lifting mechanism, running mechanism and trolley frame.
Electrical system:
Includes components such as motors, controllers and brakes.
The electrical system controls various actions of the crane to ensure its safe and reliable operation.
II. Working principle
The double-girder crane lifts heavy objects through the lifting mechanism of the lifting trolley, and then moves the heavy objects to the designated position through the running mechanism of the trolley and the traveling mechanism of the crane. During the working process, the electrical system controls the actions of each mechanism to realize the automatic operation of the crane.
In conclusion, the double-girder crane is a lifting equipment with excellent performance, safety and reliability, and plays an important role in industrial production and logistics transportation and other fields.
