Span: 7.5m~35m ( Customized ) Lifting Height:6~100m ( Customized )
Working Class: A5,A6
Double Girder Gantry Crane Supplier With Competitive Price design and produced according to Chinese national crane design standard GB/T 14406 or International crane design standard. Mainly is made up of bridge beam, trolley, crane traveling mechanism system and electric system. All working procedures are finished in the operating cabinet room. Applied to the open warehouse environment or rail along for general handling and lifting work. Also can be equipped with many special lifting device for special lifting task. Prohibited for lifting under high temperature situation, flammable, explosive, corrosion, overloading, dusty and other dangerous environment
Construction gantry crane, is used to lift, move, load and unload the bridge girder in the precast girder yard for the construction site of the high way, railway, high-speed railway, intercity railway, etc. 
Its cross girders with truss structure. Truss structure has characteristic of small windward surface, small self-weight and strong lifting capacity.
