Double Girder Gantry Crane

A gantry crane which is sometimes called the giant crane or the portal crane refers to a kind of lifting equipment that is purposely designed to load and unload materials in various industrial environments/sites such as the factory, power plant, warehouses and even in workstations. This crane resembles an overhead crane. An overhead crane is used for lifting and transporting material in a factory, warehouse, or a workshop. It has a single girder type and double girder type and travels on the rail of the building or supporting structure just like the gantry crane. But, the gantry crane has two supporting legs and can be used for indoor/outdoor lifting and transporting work.

Our company has years of experience in designing and producing industrial devices, such as overhead crane, gantry crane, marine winch, construction winch, travel lift, steel structure, flat transfer cart, and a smart car parking system. Gantry cranes have become very popular over the past few decades due to their well-designed structures and the great benefits that they bring to an organization. They can be classified as single girder cranes, double girder cranes, semi-gantry cranes, engineer cranes and operate on floor-mounted rails.


This is a crane that is designed to carry heavy weighted materials. It has a strong carrying capacity and a large span. The two strong beams make it very rigid and its structure can adopt the European style configuration known as the European double -beam gantry crane.

Types of double girder gantry crane

Truss type

(1). Truss type double girder gantry crane

This crane is suitable for open areas and is considered to be strong wind resistant. It adopts an open winch as its lifting mechanism. Its parameters include:-

  • Lifting capacity: 5t-200t
  • Span length: 18m-35m
  • Lifting height: 6m-18m
  • Working class: A5
  • Traveling speed: 28m-45m/min
  • Lifting Speed: 3.5m-12.5m/min

(2). A-type double girder gantry crane

This can be classified into two broad categories:
-According to the form of use, that would include the hook type and the project type
-According to the structure of the main beam, that includes the box type and the truss type

. Hook type

In this case, the crane has an auxiliary hook in addition to the main hook. An example is the MGA double girder gantry crane with the following parameters:-

  • Lifting capacity: 5t-200t- Span length: 18m-35m- Lifting height: 6m-18m- Working class: A5- Traveling speed: 28m-45m/min- Lifting speed: 3.5m-12.5m/min
    . Project type

This machine adopts the structure of the truss type, has less weight and wheel pressure, and its performance is reliable
(3) U-type
This has a unique feature of having a larger space between the two supporting legs. Example of such a crane is the MGU double girder gantry crane. with the following parameters:-

  • Lifting capacity: 5t-200t
  • Span length: 18m-35m- Lifting height: 6m-18m- Working class: A5 or A6- Traveling speed: 38m-44m/min- Lifting speed: 5.9m-13.2m/min

General features of double girder gantry crane

It’s easy to install and operate.

It has safety devices

Every feature is reliable

Heavy duty and long life service

Works well in all occasions, whether indoor or outdoor.

Other equipments that go along well with this crane is the marine winch which is mainly used on a boat, shore, port for anchoring, fixing, mooring or towing winch. A construction winch which is also applied for pulling or lifting material in an industrial site, factory, warehouse, or mine as well as a travel lift for lifting the boat from the water, putting the boat into the water, transporting the boat on land, or for maintenance work.

If you are having a construction project, consider using the steel structure. This is a kind of light material for building factories and warehouses and makes the building process simple, fast and safe. You may also need to add a flat transfer cart since it has a wide application in a factory for transporting steel plate or other material. Lastly, you can save your clients and employees the struggle of fighting for a parking space by installing a Smart car parking system that saves much land area and parking time
