Description
Hydraulic Liftgate Pump systems for trucks are compact DC hydraulic power units (typically 12V or 24V) used to raise and lower cargo liftgates. A Hydraulic Liftgate Pump usually integrates a motor, pump, and reservoir in a single unit for easy installation on trucks. Common options include single-acting (gravity down) and double-acting (power up/down) designs, with power ranges around 1.6kW–2.2kW, ensuring efficient and stable loading operations.
Key Features and Types
- Voltage: Mostly 12V DC for standard trucks, with 24V or higher available for heavy-duty applications.
- Acting Types:
- Single-Acting: Used for lifting, while gravity handles the lowering of the tailgate.
- Double-Acting: Used when hydraulic force is required for both lifting and lowering, offering better control.
- Components: These systems generally feature a hydraulic motor, pump, solenoid valve, and oil tank (reservoir).
- Specifications: Typical power ranges from 1.6kW to 2.2kW. The units often feature high-pressure relief valves (e.g., 2900 PSI) for safety

Precautions
- Due to various types of hydraulic system failure, over 80% of issues are caused by hydraulic oil. Proper use of hydraulic oil is essential for Hydraulic Liftgate Pump reliability. Oil viscosity should be 22–46mm²/s per ISO3448. Filter oil with a 10–30μm filter before use. N46 hydraulic oil is recommended.
- Clean all hydraulic components before installing the system. For a hydraulic pump for lift gate, check oil level after initial operation to ensure stable performance.
- Oil change is required after the first 100 operating hours, then every 3000 hours. We can provide units with customized power, flow, pressure, and tank capacity for your tailgate hydraulic pump applications.
- Install the electric hydraulic pump in a horizontal position. It is designed for S3 duty (30 seconds ON, 270 seconds OFF).
- To maintain thermal balance, the duty ratio between interval time and operation time of the mini hydraulic power pack should be 1:9.
