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.
