CE Electric A5 16/3.2T Double Girder Gantry Crane 5.9-11.3m/Min Lifting Speed

Heavy Duty Electric Double Girder Gantry Crane CE Certification

General description:

The gantry crane is a bridge-type crane in which the bridge is supported on the ground track through the outriggers on both sides. In structure, it consists of gantry, cart running mechanism, lifting trolley and electrical parts. Some gantry cranes only have outriggers on one side, and the other side is supported on the factory building or trestle, which is called a semi-gantry crane. The upper bridge frame of the gantry crane (including the main beam and end beam), outriggers, lower beams and other parts. In order to expand the working range of the crane, the main girder can extend beyond the outriggers to one or both sides to form a cantilever. A hoisting trolley with a jib can also be used, and the crane's operating range can be expanded through the pitching and rotation of the jib.

Double girder gantry crane with hook is applied outside warehouse or railway sideways to do common lifting and unloading works.

This kind of crane is composed of bridge, supporting legs, crane travelling mechanism, trolley with strong lifting winch, electric equipment and control system.

As its heavy duty design, it can be widely used in all kinds of industrial field. As its heavy duty design, it can be widely used in all kinds of industrial field.

Advantages of Double Girder Gantry Crane:

• Because gantry cranes ride on the ground rather than on overhead runways, they don't require a runway structure.
• Nor do they usually require concrete foundations.
• Their installation is fast and simple.
• Gantry cranes sometimes can provide a significant cost saving than bridge crane accodring to the environment.
• Simple and compact structure
• Light weight
• Steady performance
• Easy maintenance
• Less wastage

Technical Parameters:

Main beam structure:

1. Truss beam
The structural form welded by angle steel or I-beam has the advantages of low cost, light weight and good wind resistance. However, due to the large number of welding points and the defects of the truss itself, the truss beam also has the disadvantages of large deflection, low rigidity, relatively low reliability, and frequent inspection of welding points. It is suitable for venues with low safety requirements and small lifting capacity.
 

2. Box girder
The steel plate is welded into a box-type structure, which has the characteristics of high safety and high rigidity. Generally used for large tonnage and super tonnage gantry cranes. Box girder also has the disadvantages of high cost, heavy self-weight and poor wind resistance.

How to choose:

1. Selection of gantry crane
 

2. Span and cantilever length
 

3. The principle of determining the wheelbase
 

4. The gantry crane spacing size is determined
