Single-Acting Hydraulic Power Unit
Boost Your Machinery's Efficiency with Our 3 Hydraulic Power Units Series
Hydraulic Solutions Since 1986
GRH focuses in the design and production of hydraulic products that can be used in various fields. Our hydraulic power units are integral to the smooth operation of engineering and agricultural machinery, material handling equipment, and even within the demanding realm of oil extraction. This versatility is a testament to our commitment to delivering hydraulic solutions that are not only robust but also adaptable to diverse industrial applications.
GRH offers a wide range of power units for car lifts, combining high-pressure gear pumps, AC motors, hydraulic valves, and tanks into a cohesive unit. These power units control the start and stop of the power source and the direction of hydraulic valves, driving and managing the end mechanism. They're especially useful for dual-column car lifts, offering lifting functions and controlled descent through throttle valves.
- Customizable to meet specific requirements
- Compatible with complex hydraulic systems
- Compact design, low noise, high efficiency, and energy saving
- Made with our own high-quality core components, ensuring stable product performance

These hydraulic power unit units are used in the automotive industry, including car repair shops, residential parking systems, and mall parking systems, facilitating vehicle lifting and movement.
The power units for semi-electric pallet stackers are a combination of high-pressure gear pumps, DC motors, stack valves, and reservoirs. They feature manual unloading valves with microswitches, allowing the stacker's lifting and lowering to be controlled by the valve handle. The descent speed is automatically controlled by an in-built pressure-compensated throttle valve. Our single-acting power units are customizable, compact, quiet, efficient, and energy-saving, and are made with our own high-quality core components for stable performance.
- Our power units can be customized
- Compact structure, low noise, high efficiency and energy saving
- Stable product performance with in-house high quality core components
