single girder gantry crane

Single girder gantry crane, door crane, mobile gantry crane 
MH model single beam gantry crane with hoist is matched with CD MD hoist, a kind of track travelling small and MID-light type crane, applied 3-32t capacity, span 12---30m, working temperature within -25 to 40. 
This product is an ideal crane, widely used at outside warehouse for loading unloading and lifting. Both ground and cabin control. 
MH model gantry crane have box type and girder type two types, box type has characteristice of slim body and strong lifting capacity; Girder type has characteristice of small windward surface, small deadweight and strong lifting capacity. 
The profiles of the main girder are optimally produced using a integrated technology which is weld less, so that maximum performance with a minimum of deadweight can be achieved. 

Standard Features: 

Design: "Kuangyuan' Brand Electric Overhead Traveling Cranes are designed & manufactured accordance with ISO 9001: 2000 ISO 14001: 2004 and OHSAS 18001 considering factor of safety in respect to appropriate class of duty.
