China Hot-selling QY25K5D Truck Crane with 25 ton Lifting Capacity
Product Description
Service brake: double-circuit air pressure brake, acting on all wheels. Parking brake: spring energy brake, acting on wheels of 2-3 axles. Auxiliary brake: engine exhaust brake and engine in-cylinder brake.The safety devices contains Hydraulic balance valve, Hydraulic relief valve, Double-way hydraulic valve, LMl, spring aligning device for joystick, Lowering limiter for preventing wire rope from over-releasing; Anti-two block at boom head for preventing wire rope from over-winding, tricolor warning lamp.
Efficient hydraulic system
Adopt large flow double variable piston pump, sufficient flow but no waste, efficient operation, energy saving and environmental protection; Using the new intelligent flow distribution main valve, the combined action is time-varying; using the post-valve compensation technology, the flow is distributed on demand, with excellent fretting and controllability, meeting various precise hoisting requirements; The pressure drop when the elevation angle is large, and the self-weight drop when the elevation angle is small, the flow compensation technology can automatically limit the speed to ensure a uniform and stable drop; Integrate boost buffering, sequential braking and free-slip technology, and the turning start and stop is soft and stable.
