A Type Double Girder gantry crane

A type double girder gantry crane adopts A-type door frame. The bridge is welded structure of box-type; individual drives are adopted for traveling mechanism on each end of the crane. All movements of the crane are controlled in the cabin.

U-type Double Girder Gantry Crane

This type gantry crane adopts U type door frame, it consists of main parts, namely, the bridge structure, the traveling mechanism, the cart and the electric equipment.

Similarities of “A”&“U” Model Double Girder Gantry Crane

• They all have compact structure and save construction cost.
• Light dead weight and light wheel load.
• Large span length and strong rigidity, reliable to use.
• Lift heavy-duty goods.
• Two of them are well received by customers.

Differences of “A” type and “U” type Double Girder Gantry Crane

• “A” model crane contains saddle and cantilever but “U” model not.
• When lifting goods or materials, “U” model crane would decrease its height.
•  Due to large space between two legs, “U” model gantry crane suits to lift the large size goods and materials, while “A” model crane suit the relatively smaller size goods.

Advantage of Gantry Crane

Gantry cranes have become a widely accepted alternative to overhead cranes. This type of crane is similar to the overhead crane except that it runs on a runway at the floor level. The bridge is supported by a pair of rigid steel legs which are carried by a pair of end trucks along the floor level runway.

• often costs less than overhead crane
• built to heavy duty specifications, which meet the demands of high duty cycles and multiples shift operation, as well as providing decades of reliable service for all applications
• available in spans to 60 feet and capacities to 550 tons
• can be used either indoors or outside

Considering the diversity demands, after some successful cases with clients, DQCRANE makes summary to emphasize on crane diversities.

Crane Diversities here doesn’t mean customized cranes according to dimensions only, DQCRANE provide crane designs according to the workshop site working demands, at the same time to provide the solutions to meet the clients price, quality and site working requirements, take single girder overhead crane for example:

Chinese Traditional overhead crane Design:

Generally, the girder of single girder overhead crane is I-beam, and lifting mechanism is Chinese traditional wire rope hoist, like below pictures, Chinese traditional type crane has its own advantages: mature design, high safety standards, it is China’s historical heritage with thousands of practice, most clients prefer this design, because they believe in Chinese mature technology.

In order to reach diversity demands from clients, DQCRANE provide the following more combinations for your options:

Overhead Crane Design 1:

• Girder: box type
• Lifting hoist: European style wire rope hoist

This type has advantage of less maintenance, light weight, compact structure, save much construction cost and future maintenance cost, in addition, three-in-one driving systems make the whole crane in good performance.

Overhead Crane Design 2:

• Girder: box type
• Hoist: Chinese traditional low headroom wire rope hoist

This type of crane is developed on the basis of traditional type, it is designed to improve the lifting height, used in the workshop with limit height space, and the most important is that this type can not only meet the height requirements, make full use of space, but also the price is between traditional and European type, it is with the advantages of the above two.

Overhead Crane Design 3:

• Girder: box type
• Hoist: Special design wire rope hoist

This type of combination make good use of the joint between hoist and girder to improve the whole performance of crane, of course the price is lower than European style and higher than the traditional type; this type demands are increasing now.

Overhead Crane Design 4:

• Girder: I-beam
• Hoist: electric chain hoist

The combination has same performance with traditional type, some clients prefer use electric chain hoist. It is good-looking and make the workshop clean and tidy, because chain bag can put away the chains when it is not used. Of course the low headroom type can improve the lifting height.
