Product Introduction
Gantry Crane are also known as Portal crane or Goliath crane. Include single girder gantry crane, double girder gantry crane, truss gantry crane, semi gantry crane, and operate on floor mounted rails.
In general, truss gantry crane have three kinds of uses. First, truss gantry crane usually used in concrete beam yard, for lift beam girder which is used in bridge build. And there will have a hoist traveling under the crane main girder for lift light and small tools or material. Second, Engineer gantry crane will used near to the bridge approach, for construct bridge approach, after finished, engineer gantry crane also for lift concrete beam from ground transporter to bridge transporter, help launcher crane to build the whole bridge. Third, engineer gantry crane is used for disassemble and re erect launcher crane.
In order to facilitate move the gantry crane from one erect point to next erect point and save cost, usually, we will provide moveable steel box foundation for engineer gantry crane.
Application:
Truss gantry crane is mainly used in Concrete beam yard and Bridge build, also used for Steel, Forest Products, Intermodal, Biomass/Pellet and many other industries.
Features
- Gantry cranes are more quickly and easily for installed and disassembled
- Equipped with all the necessary safety device
- Equipped with movable steel box foundation
- Usually equipped with one set hoist to lift light and small tools or material
- Speed is slower than general gantry crane, more safety
- Lifting mechanism is open winch
More Details
Steel structure
Q235/Q345 carbon structural steel. Crane with truss type can bear strong wind and reducer self-weight
Support leg
Engineer gantry crane will equipped one side rigid leg, the other side flexible leg, it is for reduce gnaw rail probability
Wheel group
Equipped with high quality forged wheel, strong crane wheel cover and famous brand motor
Open winch
With heavy capacity and high work duty, open winch was developed specifically for lifting that requires accuracy and smooth movement
Electric equipments
For crane and winch power supply, usually we equipped Schneider, ABB, Siemens brand, And inverter equipped Yaskawa brand
Crane motor
Crane traveling motor include YZR/YZP/Three in-one model, brand is Wuxi Hongda/Boneng/Guomao

Client Care
You might be interested in the following questions
-
What information shall we offer to get precise quotation & best design?
- Capacity: __ton?
- Span length: __m?
Any canteliever do you need? Left cantilever: __ m? Right cantilever: __ m? - 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? Wind? Humidity? Slope?
- 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 concrete beam yard for manufacture and lift concrete beam, we will design engineer gantry crane for your case.
- If the crane is use matched with launcher crane, we will design engineer gantry crane for your case.
-
In concrete beam yard, if the engineer gantry crane is also suitable for lift light tools or material?
When we design engineer gantry crane, we will equipped one set hoist for the crane, with small power, for lift light tools or material, it can save the cost and extend the main lifting mechanism lift.
-
How many sets crane is more suit for us?
Usually in the concrete beam yard, two sets engineer gantry crane will traveling on the same rail and operate together to lift one concrete beam, but the crane also can operate separately.
-
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 temperatureis 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.
