Electric hoist double girder overhead cranes are suitable for lifting workpieces with a load range of 5t to 50t. The crane features flexible installation, compatible with both newly built and renovated existing workshops, and comes with abundant functional modules for intuitive operation. Benefiting from compact layout, light dead weight and large effective lifting height, this model is extensively adopted in production workshops, metallurgical processing zones, storage warehouses and equipment assembly plants.
Weihua’s electric hoist double girder overhead crane adopts aesthetic fully welded box main girders optimized via computer simulation calculation, which balances outstanding mechanical performance and lightweight design. The maximum customizable working span can reach up to 40 meters.
Weihua full-series overhead lifting equipment is widely deployed across mechanical manufacturing, metallurgical smelting, power generation, railway logistics, port terminals, petroleum exploitation and chemical processing sectors. Our lifting machinery provides stable heavy-load handling support for numerous national key construction projects and production bases of large industrial conglomerates worldwide.
Twin box-type main girders formed by full automatic welding process
Fabricated from premium Q235B and Q345B carbon structural steel plates
Main girders and end carriages connected with high-strength bolt assemblies for easy disassembly and transportation
All critical welding joints pass X-ray and ultrasonic non-destructive flaw detection to eliminate hidden welding defects
