Double Girder Overhead Crane

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 a welded box-type solid web structure, including normal rail box type and deviated rail box type. The crane is equipped with two parallel main girders with prefabricated camber, which effectively compensates deflection deformation under heavy load and ensures stable operation. The main girder is fitted with maintenance walkways and safety guardrails to provide safe conditions for daily inspection and maintenance work.

02 End Girder

End beams are transverse load-bearing components installed at both ends of the crane bridge. They connect the two main girders to keep parallel arrangement and stabilize the overall bridge structure. Wheel sets are mounted at the bottom of the end beams. Driven traveling wheels enable the whole crane to move smoothly along the track. The end beam adopts a split structure, which can be disassembled for transportation and bolt-assembled on site for convenient installation.

03 Hoist Trolley Winding Mechanism

The hoist trolley is the main winding operation mechanism of the crane, equipped with main hook and auxiliary hook. It can be matched with various lifting accessories such as lifting hooks, electromagnetic chucks, grabs and clamps. Installed on the rails of the double main girders, the hoist trolley can move transversely along the girders and complete vertical lifting of goods with the winding system. It supports diversified lifting operations and meets various working condition requirements for material handling.
