Double Girder Overhead Crane - Know what They Are and Primary Advantages

A Double Girder Overhead Crane is used to lift big and medium objects. These cranes, which use two beams placed next to one another, can carry heavier loads because they provide more stable support for the lifted cargo. For loads more than about 10 tonnes, it is usually recommending a twin girder crane design.

Double Girder Overhead Cranes: What Are They?

Two or more runways are installed into the roof of the building to support a bridge crane, and the bridge itself consists of two girders spanning the width of the crane bay.

End trucks are attached to the extremities of the girders and move the entire assembly, hoist and all along the runways. Typically, the top of the girder is where you'll find the trolley and hoist.

Advantages of this overhead crane

• High stability and design rigidity;
• Low cost;
• High efficiency and stable performance;
• A flexible, modular layout.

Features of these Overhead Crane

• The deadweight of a Double Girder Overhead Crane is kept to a minimum, allowing for greater load capacity.
• By placing the crane hook in the centre of the two girders, this type of overhead crane can achieve greater lifting heights and more precision in its material handling operations.
• The lifting capacities of these overhead cranes are practically limitless.
• Two hoists on a single trolley or two independent hoists could be fitted on a double overhead crane.
• These types of overhead cranes are equipped with pendants and radio controls to guarantee safe operation and can travel at speeds of up to 200 feet per minute, which is significantly faster than under-hung cranes.

Advice on Choosing the Appropriate Overhead Crane

Weight Capacity

The primary concern is the number of objects you will have to move and relocate. Overhead cranes with two girders are built to handle big loads repeatedly. 20-ton loads and up are the norm here.

Investing in a double-girder overhead crane supplied by Double Girder Overhead Crane Suppliers in India would be excessive if you only need to lift and transport loads that total less than 20 tonnes. Investing in a single-girder crane will help you save both time and money.

Span

After that, you should examine the range in which your crane will function. A Single Girder EOT Crane is usually necessary for cranes with a span of more than 60 feet. Remember that rolled section girders for cranes taller than 60 feet typically need to be joined together, significantly increasing the crane's weight.

Size of the Hook

On each beam of the runway is an atop-running, overhead crane. Overhead, on the underside of each runway beam, is a double-girder overhead crane, also known as an underhung crane.

A top-running crane can hold more weight than a bottom-running one. They have the highest hooks and the most headroom. Select a top-running crane if you need a high hook height or headroom.

Conclusion

In terms of lifting, a twin girder overhead crane is among the most excellent options. The crane is constructed so that moderate and heavy weights can be hoisted relatively quickly.
