Overhead cranes brief introduction:

1,Mainly composed of bridge, crane traveling mechanism, trolley, electrical equipment, etc. ;

2. three ways to enter to the cab: from side, fromend2,Design and manufactured in accordance with GB/T 14405, 

General Bridge Crane;

3,Widely applied to loading and moving of normal weight in the fixed crossing space and also can work with various special-purpose hoists in special operations;4,It is prohibited to use the equipment in the combustible, 

explosive or corrosives environment. Feature Description:Optimazed designing, smaller wheel load, space saving 

Max. Safe working load  50tFlexible solution for all lifting needsExcellent driving properties, stepless control, smoothly moving .                                     

Mechanical feature 

Dobule welding box girder, DIN/FEM standard deflection.Adopt high quality carbon steel, Q235B or Q345B; (similar as Fe37 or Fe52); Whole length CNC cutting for complete web plate, high deflection accuracy. High quality autometic welding and NDT inspection Shot-blasting Sa2.5 for complete girder after welding, stress releaseTrolley rail is high strength flat steel bar 10.9 class High tension bolts mouting between girder and legs, life time safety connectionhigh quality paiting, 2x2 with 140μm , beautiful appearance End girder is matched with rail buffer and rail clearance device, anti-friction bearings  Full-length service platform along the crane bridge is supplied,where it si equippe with protective hand railing and toe strips.
