This hydraulic power unit is designed for telescopic belt conveyors. It integrates a high-pressure gear pump, AC motor, center valve block, cartridge valve and oil tank to provide an integrated hydraulic solution.

After starting the motor, the hydraulic system drives the equipment to rise; when descending, the solenoid valve is opened to control the descent by its own weight.

The built-in pressure compensation valve ensures that the equipment can achieve a uniform descent speed under no-load and load conditions, avoiding unstable speed fluctuations.

There are 1.5–4 kW optional motors, 220–380V optional voltages, and iron and plastic oil tanks to choose from.
