Gantry Crane are also known as Portal crane or Goliath crane. Include single girder gantry crane, double girder gantry crane, engineer gantry crane, semi gantry crane, and operate on floor mounted rails.
Dafang provide double girder gantry crane solutions from 1 Ton SWL up to 800 Ton SWL (we also manufacture gantry crane designed according to client special requirement). Double girder gantry crane have more heavy capacity and higher work duty than single girder gantry crane.
Double girder gantry crane custom-engineered lifting solutions can be designed with two side cantilever, one side cantilever or no cantilever.
The control method could be pendent control, remote control, cabin control or both, we also can equipped adjustable seat, toughened glass for the window, fire extinguisher, air condition, acoustic alarm and interphone in the cabin.
Double girder gantry crane is mainly used in Steel, Forest Products, Intermodal, Biomass/Pellet, Concrete and many other industries.
- Gantry cranes are more quickly and easily for installed and disassembled, it is ideal choice for use in a rented factory or in multiple work place
- Equipped with all the necessary safety device
- High reliability component
- High work duty, can bearing heavy capacity and long time work
- Needn't any column, runway beam, just travel on the ground
- Suit for both of outdoor and indoor
Crane traveling motor include YZR/YZP/Three in-one model, brand is Wuxi Hongda/Boneng/SEW
Equipped with high quality forged wheel, strong crane wheel cover and famous brand motor
With heavy capacity and high work duty, was developed specifically for lifting that requires accuracy and smooth movement
For crane and winch power supply, usually we equipped Schneider, ABB, Siemens brand. Inverter equipped Yaskawa brand
Make main girder divided into two or more parts, convenient for transport by container, and assemble with strong bolt
Q235/Q345 carbon structural steel. Main beam with strong box type and standard deflection

- Lift height: __m? (hook center to ground)
- Traveling distance: __m? Do you need us provide rail and cable?
- Which material to lift?
any special requirement on lifting speed, hosit traveling speed and crane traveling speed?
- Work frequency: like how many times/day, hours/time?
So that we can confrim which type is more suit for your case: like double girder or single girder?
- Woring condition: temperature? Any corrosive gas or material? Any explosive gas or material?
- Power supply: 220/380/400/440V, 50/60Hz, 3Ph?
- Which type crane is the most suitable one for us?
- If the crane is used in open area and wind is very strong, or crane is used for lift concrete beam, you'd better choose truss type gantry crane.
- If the goods size is very big, and crane have cantilever, you'd better choose U type gantry crane.
- A type crane is suitable for general condition, both can used indoor and outdoor.
- Under which condition we should to choose gantry crane?
- If crane is used in door, and the workshop haven't column, or you just rent one workshop, we suggest you choose gantry crane, it can be save the column cost and it is more convenience erect and disassembly.
- When the crane used outdoor, usually, gantry crane is more suitable.
- When work temperature under 20℃, what is the crane different? When work temperature is too high, what is the difference.
Under 20℃, the crane's steel plate will reply by Q345. When temperature is too high, will use H grade motor, and increase the cable's insulation grade, also will increase the crane's ventilation.
- Whether you can offer the matched spare parts?
Yep, as crane manufacturer, we offer all the related spare parts, such as motor, hoists, drums, wheels, grabs, hooks, rails, travel beams, enclosed bus bar etc.
- What kind of operate method you can offer?
By pendent button/By remote control/By cabin.
