Product Details

20 ton box girder monorail electric hoist gantry crane with cantilever

Design, Features & Specifications:Traveling rail crane, light crane rail is the best light crane, which is used both in multi-wind area and workshop for inside and outside. It is composed of metal structure, cart operating mechanism, electric device and trolley (electric hoist). The surface of facing wind is very small, because of its steel-pip leg, and is characterized in the light deadweight and strong hoisting capacity. It has ground-controlling and remote-controlling. The lifting capacity is 2~20t, the span is 10~30m, the ambient temperature is no more than 40°C, and wind-pressure is less than 125Pa.


The profiles of the main girder are optimally produced using an integrated technology which is weldless, so that maximum performance with a minimum of deadweight can be achieved.


The specification of the single girder gantry crane is as follow:

Product ModelMH
Lifting Capacity0.5-32 ton
Lifting HeightAccording your demands
Voltage220-660V 3Phase
