A General Overview about Double Girder Cranes

In the world of heavy lifting and machines cranes have a special position. These are mechanical weight lifting devices with winder, wind ropes and sheaves used for lifting and moving of weights. The history of iron and steel crane using dates back from Industrial Revolution when introduction of such devices were primarily responsible for the revolution itself. Before that wood, animal labor or human treadmills were used for the heavy lifting part. According to their structure and function there are different types of cranes. One such crane for heavy duty and heavy lifting is the Double Girder Crane.

Structure and function

Among the many different types, this double girder type is recommended for its heavy duty and longer longevity. Structurally as the name suggests a Double Girder Crane has two girders beams making up for the bridge of the crane which are supported by two end trucks on two sides. This double girder design is beneficial for gaining a depth of the cross girder, if the hoist is structured in between or on the top of the cross girders. This enables it to gain an extra hook height of around 18’’-36’’ mostly.

Functionally, as mentioned already this type of crane is mostly recommended when the applications are heavier and the life span for crane requirement is longer. Although because of this heavy duty and longer life span the hoist, trolley and the complete design of crane becomes bit complex. The prices are increased significantly as well. Yet these types are more frequent in use. Not only in outdoors but these cranes can be used indoors as well. The major areas where these cranes find their uses are bridge constructions, gantry setups, mining areas, iron and steel production plants, rail yards and shipping ports.

Major advantages 

Now that the structure and functions of this kind of crane is discussed the question regarding its advantages arises. A few advantages are listed below:

• Greater height for hook

• Infinite capacity and life span

• Is ideal in production, transportation industry

• Perfect for heavier load lifting

• Certain features like walkways, maintenance platforms, cabs, magnetized reels, extra lights etc. can be added to the setup for specific purposes.

• Can be used both indoors and outdoors.

The best seller

It is beyond doubt that a double girder type of crane is highly advantageous from workload, industry and longevity prospect. However as said such machine is cost expensive and while buying care should be taken about the quality of iron and steel used, the expertise of the company and most importantly the experience of the seller in manufacturing heavy machineries. After checking all these points, pick the best seller, get the quote and set your own double girder type crane.
