30 ton Crane Truck STC300E5 STC500E5 STC800E5 Industrial Crane
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.
