It is compatible with multiple mainstream mobile crane models, including 25-ton, 30-ton, 50-ton and 70-ton truck cranes. As the central control core of the whole machine, it precisely manages lifting amplitude, slewing operation, load limitation and hydraulic system coordination. Produced in full compliance with OEM industrial standards, it features standard pin definition and program protocol, supporting plug-and-play installation without additional programming or circuit modification.

This controller features compact and durable construction, with overall dimensions of 210×150×65mm and a net weight of 1.25kg. Adopting industrial-grade anti-interference chip and fully sealed waterproof and dustproof shell, it maintains stable signal output under strong vibration, high temperature and dusty working conditions. It effectively solves common faults such as system report error, unresponsive operation, lifting limit failure and hydraulic disorder. With high operational accuracy and strong environmental adaptability, it ensures safe, stable and efficient lifting performance for truck cranes on construction sites.
