The hydraulic system of the vehicle-mounted crane (trailer crane / truck crane) is the core of the entire machine's power and control. It uses high-pressure hydraulic oil as the medium and is realized through components such as pumps, valves, cylinders, and motors to achieve five major actions: lifting, slewing, telescoping, rotation, and leg extension. It features high power density, precise speed control, smooth operation, and safety and reliability. It is suitable for applications in construction, logistics, and municipal services.

A 5-ton truck-mounted crane with a maximum lifting height of 27 meters, featuring a hydraulic telescopic boom and 360° full rotation. Structure: multi-section telescopic hydraulic arm, H-shaped hydraulic legs. Applicable fields: Construction work, material hoisting, steel bar and formwork lifting, materials loading for self-built houses, equipment loading and unloading at construction sites, high-altitude work assistance

4-16 ton truck-mounted crane (tractor-mounted crane), installed on a truck chassis, is a small-sized boom crane with movable structure. It is a type of portable lifting equipment that can perform both transportation and lifting functions in one vehicle. It is flexible, efficient, and can recover the investment quickly.
