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 Gantry crane legs
The legs connect the main girder and the bottom travelling bogies, available as single rigid legs or a combined structure of rigid legs and flexible legs. They are integrally welded with thickened section steel, featuring high structural strength, favorable torsion resistance and reliable wind load bearing capacity. Cable routing channels are reserved either inside or outside the legs, and maintenance ladders together with safety guardrails are installed on the outer side. The height and section form can be customized according to site span, load capacity and wind pressure requirements, suitable for long-term outdoor open-air operation and guaranteeing stable operation of the whole crane.
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.
