811W41723-6008 Lifting Oil Pump

The Lifting Oil Pump 811W41723-6008 is a specialized cab lifting/flipping pump assembly designed for vehicles such as Sinotruk Howo T7H and SITRAK C7H. As the core component of the vehicle's hydraulic lifting system, it serves crucial functions.

Product Function

1.Hydraulic Power Output

The pump provides the hydraulic power required for cab lifting and tilting. When the manual pump's directional control valve is rotated to the lifting position, raising the operating handle draws hydraulic oil from the tank into the pump body via the piston. Lowering the handle then forces the oil through hydraulic hoses into the cylinders under the action of the manual pump piston, thereby achieving cab lifting.

2.Safety Control Function

The pump utilizes an advanced directional control valve design. A dedicated tool directly actuates the valve spool for direction change, effectively avoiding accidental shifting common in traditional sleeve-pin structures. This design prevents accidental valve operation due to external factors during driving, ensuring the pump's shift lever remains in the safe position.

3.Pressure Regulation Function

The pump provides stable hydraulic pressure according to operational needs. This allows the cylinder to remain stationary at any position, supported by the check action of the hydraulic control check valve, enabling precise cab positioning and stable support.

Main Purpose

1.Cab Maintenance and Repair

The primary purpose of the lifting oil pump is to raise and tilt the cab when maintenance or replacement of key components (like the engine or transmission) on trucks or engineering vehicles is required.

2.Routine Vehicle Maintenance

By lifting and tilting the cab, it facilitates daily inspection, maintenance, and repair of vehicle components such as the chassis, steering system, and brake system, improving maintenance efficiency.

3.Specialized Vehicle Compatibility

This product is primarily compatible with heavy-duty truck models like Sinotruk Howo T7H and SITRAK C7H. It is an OEM-grade part, ensuring perfect compatibility and reliable operation with the vehicle systems.
