Product Introduction

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.

Application:

Double girder gantry crane is mainly used in Steel, Forest Products, Intermodal, Biomass/Pellet, Concrete and many other industries.

A Type Double Girder Gantry Crane	Truss Type Double Girder Gantry Crane	U Type Double Girder Gantry Crane

Suitable for indoor and outdoor Gantry crane is designed for maximum flexibility and reduces structural and rail maintenance to a minimum. The open design is easy inspection of imperfection throughout the life of the crane. Crane equipped with general winch, winch traversing on the main girder	Crane main girder and support leg both with truss type, it is more suitable for open area, can bear strong wind pressure. Crane self-weight is lighter than the single girder gantry crane with box girder, also will reduce the cost. Usually used in outdoor, concrete beam yard, as engineer gantry crane, and lifting mechanism usually is open winch.	Crane design with U type, is it more convenience for large size goods from middle position move to cantilever without any dimensional limit of support leg, like gantry crane which used in the hydropower station with very large wheel gauge. Crane usually equipped with lifting spreader, when the crane used for lift stoplog, lifting mechanism will be with two lift points.

Client Care

You might be interested in the following questions

What information shall we offer to get precise quotation & best design?
1. Capacity: __ton?
2. Span length: __m?
  Any canteliever do you need? Left cantilever: __m? Right cantilever: __m?
3. Lift height: __m? (hook center to ground)
4. Traveling distance: __m? Do you need us provide rail and cable?
5. Which material to lift?
  any special requirement on lifting speed, hosit traveling speed and crane traveling speed?
6. 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?
7. Woring condition: temperature? Any corrosive gas or material? Any explosive gas or material?
8. Power supply: 220/380/400/440V, 50/60Hz, 3Ph?
Which type crane is the most suitable one for us?
1. 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.
2. If the goods size is very big, and crane have cantilever, you'd better choose U type gantry crane.
3. A type crane is suitable for general condition, both can used indoor and outdoor.
Under which condition we should to choose gantry crane?
1. 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.
2. 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.
