Heavy Duty 50 tons Double Girder Gantry Cranes
MG(A) type double girder gantry crane with trolley are usually used in outdoor storage, stock grounds, railway warehouses, and seaport docks. It also can be used in special operation with various hooks. It consists of four main parts, bridge structure, traveling mechanism, trolley and electric equipment. The bridge is welded structure of box-type girder. All movements of the crane are controlled from the cabin. Either rigid shapes of steel (angles or tees) or flexible insulated cable shall be selected to be utilized as runway conductors.
Mechanical feature1)Dobule welding box girder,legs, DIN/FEM standard deflection.2)Material Q235B orQ345B .(Similar to the international steel Fe360 or Fe520)3)Whole length CNC cutting for complete web plate, high deflection accuracy.4)High quality autometic welding and NDT inspection.5)Shot-blasting Sa2.5 for complete girder after welding, stress release.6)Epoxy zinc rich high quality paiting, 2x2 with 140μm.7)10.9 class High tension bolts mouting between girder and legs, life time safety connection.8)Double flanged or flat wheels, anti-friction bearings, cellular buffers, derailment protectors.9)Full-length service platform along the crane bridge where is equiped with protective hand railing and toe strips.
Safety protection1)Rain cover for outside hoist, driving units, electrical cubicle.2)Warning indicator: flashing lights and warning sound.3)Wireless infra-detector for anti-collusion4)Various safety limit
