The two sides of the main girder can have a cantilever girder. The lifting mechanism mainly adopts standard CD / MD electric hoist, electric hoist generally installed at the bottom of the main girder.

According to the main girder structure form can be divided into box type and truss type, cantilever design on both sides of the cantilever, on one side of the cantilever or no cantilever girder, box type single girder gantry crane main has MH type and L type, we can provide customized design according to customer’s requirements.


1.Simple and compact structure, light weight, easy install and maintenance

2.The power supply uses the track, the safety slip wire and the cable conduction device system

3.The operating view of the cab is good, the console is flexible, and the fan, heater, cooler, air conditioner and intercom can be installed according to the customers’ requirments.

4.Depending on the environment and application, gantry cranes can sometimes provide the same material handling capacity as similar bridge crane systems, but save a lot of cost.
