Description
Double girder gantry crane is composed with double girder frame, vertical legs, crane traveling end truck, and the top running trolley with lifting and travelling device.
The crane legs design is vertical to the ground, which makes the crane as U shape and allows big material to go through the legs from span range to cantilever. And the cart could be special designed for lifting and unloading dirt in subway construction site. The cranes standard speeds are adjustable, which allow the crane adjust its speed under 2~3 grades.
This model gantry crane is designed under GB regulation, passed ISO, CE certification.
The crane lifting and travelling speeds are steady and accurate.

Mechanical parts
1.Double welding box girder, beam deflection with GB/DIN/FEM standard
2.Steel Material: Chinese standard Q235B and Q345B/Q345E
3.Trolley rail is made of high strength hot rolled flat steel (16 Mn)
4.Epoxy zinc-rich painting for one bottoms and two sides of 120μm thick, to achieve a long lifespan, beautiful appearance and good luster
5.The girder and end beam are weldedtogether to ensure the structure strength and precision of the whole machine
6.The end beams are equipped with flat wheel or double rim wheels, anti-friction bearings, buffer blocks and derailment preventing end plate
7.Maintenance walkway is located on one side of the main girder, consisting of flower pattern plate, 1050meters handrail
8. Both side of all the steel plate of crane are pretreatment by pretreatment production line,Sand blasting– Primer spray–Primer drying. Eliminate the interstress of steel plate; increase the adhesive force of the steel structure. Ensure the appearance and anticorrosion quality
