Technical Parameters

Features and benefits

01 Main Girder

The main girder serves as the main load-bearing structure of the double girder overhead crane, adopting welded offset rail box-type solid web construction. The crane is equipped with two parallel main girders with prefabricated camber, which delivers favorable rigidity and anti-fatigue performance and reduces deflection deformation under long-term heavy loads. Trolley rails are directly welded to the top of main girders to realize compact structural layout. Maintenance walkways and vertical conductor frames are installed at both ends of the main girders.

02 End Carriage

The end beam adopts a box welded structure or hollow square tube structure, integrally and precisely processed by CNC machine tools. Both ends of the end beam are equipped with traveling wheels, buffers and anti-derailment baffles. The main girder and end beam are connected by high-strength bolts, allowing split transportation and fast on-site assembly. The structure features high fitting accuracy, effectively ensuring operating coaxiality, reducing traveling deviation and improving overall operational stability.

03 Hoist Trolley Winding Mechanism

The hoist trolley winding mechanism serves as the main operating mechanism of the overhead crane, equipped with main hook and auxiliary hook. It adopts integrated three-in-one hard-tooth surface drive and full frequency conversion control for stable operation and soft start-stop performance. Mounted on the rails of double main girders, the hoist trolley can travel transversely and cooperate with the winding system to complete vertical lifting and horizontal moving of loads, realizing complete material handling functions for various industrial lifting scenarios.
