This type double girder gantry crane is mainly consists of the steel structure, lifting mechanism, micro-transfer mechanism, spreader anti-sway system, crane travelling mechanism, container spreaders, electrical equipment, and other necessary auxiliary equipments. 

Compared with ship-to-shore gantry crane, the trolley of Rail Mounted Gantry Crane travels at a lower speed and usually equipped without anti-sway stabilizer, while it will be equipped with anti-sway device if users need it for reducing operation stress and improving production efficiency. For rope type lifting mechanism, increasing the rope damp is a usual way to accomplish stabilization. And for rigid type lifting mechanism, its own rigid components are available to accomplish stabilization.


(1)Double girder gantry crane is a kind of special crane with large lifting capacity.

(2)The structure type is box type structure, which consists of bridge beam structure, running mechanism, trolley operating mechanism, electrical equipment and other components, the lifting height of the crane can reach 40 meters, 

(3)Double girder gantry crane is designed and manufactured according to GB / T14406-1993 "universal gantry crane"  The lifting capacity up to 300 tons, high-tonnage cranes are mainly used in port wharf, hydropower and other work environment, work level A5 to A8. 

(4)Crane operation ground control (ground control), cab control (empty exercise), remote control operation in three forms, the user can arrange the operation mode according to the specific needs. The standard operating mode is cab control (air maneuvering), the driver's cab is equipped with a rain-proof enclosure and can be normally operated in the open air. The cranes are electrically conductive by means of flexible cables. 

(5)The trolley is powered by trolley wire or cable reel , The trolley line power supply is a common kind of conduction mode.
