40ton Double Girder Overhead Crane with European Electric Wire Rope Hoist

40Ton Double Girder Overhead Crane with European Electric Wire Rope Hoist

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.

III. Application fields

 

Double-girder cranes are widely used in factories, warehouses, docks, construction sites and other places for lifting various heavy objects such as steel, mechanical equipment and containers. It has the advantages of large lifting capacity, high work efficiency and convenient operation. It is an indispensable important equipment in modern industrial production.

IV. Safety performance
 

Limit device

Double-girder cranes are usually equipped with various limit devices such as lifting height limiters and travel limiters to prevent dangerous situations such as overtravel during the operation of the crane.

Braking device

Both the lifting mechanism and the running mechanism of the crane are equipped with braking devices to ensure timely braking in case of power failure and ensure safety.

Safety protection device

It may also be equipped with safety protection devices such as overload protection devices and windproof devices to further improve the safety performance 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.
