Two quenching cranes—with rated lifting capacities of 400 tons and 150 tons, respectively—independently developed and manufactured by China Weihua Group, have been officially delivered to a client in the metallurgical industry and are now in operation on their heat-treatment production line.
The 400-ton unit stands as the largest-capacity quenching crane currently in use in China. Together, these two cranes will handle the entire lifting process for the quenching of heavy workpieces. This delivery marks a significant milestone for Weihua in providing comprehensive, ultra-high-capacity lifting solutions for specialized metallurgical applications.

Comprehensive Thermal Protection Design for Quenching Cranes: Withstanding Sustained High Temperatures at Quenching Stations
To counter the long-term thermal radiation prevalent in furnace areas, Weihua Group has equipped its dual-hoist crane units with specialized, high-temperature-resistant cabling. The main girder houses an integrated, temperature-controlled electrical room, complemented by a dual-layer insulated operator’s cab—a comprehensive system designed to block heat transfer to critical electronic control units. By mitigating the cumulative heat generated during crane operation, this multi-layered thermal insulation strategy prevents common high-temperature-related failures, such as cable degradation and signal instability, ensuring that the quenching cranes can operate continuously for extended periods without downtime.
Weihua quenching cranes feature dual-hook coordination and a new-generation PLC, balancing operational speed with precise lifting accuracy
The quenching process is highly sensitive to timing during immersion, requiring dynamic speed matching between heavy and light loads in a dual-hook configuration. Weihua quenching cranes is equipped with the latest-generation centralized PLC control system, while the main hoisting mechanism adopts stator voltage regulation and speed control technology. This enables precise coordination of the acceleration and deceleration curves of the main and auxiliary hooks, ensuring reliable performance under complex operating conditions involving frequent starts and stops, variable loads, and high-speed lifting and lowering. The system delivers fast lifting under heavy loads and smooth, stable movement under light loads, effectively minimizing uneven quenching microstructures and impact damage caused by workpiece sway.
