811W41723-6020 Lifting Cylinder 

811W41723-6020 is a specialized cab lifting cylinder assembly designed for the Sinotruk SITRAK C7H vehicle. As a core component of the vehicle's hydraulic lifting system, it serves critical functions.

Product Function

1.Hydraulic Lifting Power Output

The cylinder provides the power for cab lifting and tilting through the hydraulic system. When the manual pump's directional control valve is switched to the lifting position, raising the operating handle draws hydraulic oil from the tank into the pump body, and lowering the handle forces the oil into both chambers of the cylinder through hydraulic hoses, thereby achieving cab lifting.

2.Safety Control Function

The cylinder features an advanced quick-connect design. A dedicated tool directly operates the valve spool for direction change, effectively preventing accidental shifting issues common with traditional sleeve-pin structures. This design prevents accidental operation due to external factors during travel, ensuring the directional control lever always remains in the safe position.

3.Pressure Regulation Function

The cylinder provides stable hydraulic pressure according to operational needs, allowing it to remain stationary at any position under the check valve's reverse locking action, enabling precise cab positioning and stable support.

Main Purpose

1.Cab Maintenance and Repair

The primary purpose of the lifting cylinder is to raise and tilt the cab when maintenance or repair of key components (such as the engine or transmission) is required on heavy-duty trucks.

2.Routine Vehicle Maintenance

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

3.Specialized Vehicle Compatibility

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