Product Detail

Product Description: Cab Lift Hydraulic Cylinder WG9719820004 for Sinotruk HOWO Truck

The Cab Lifting Oil Cylinder WG9719820004 is a genuine OEM component specifically manufactured for the Sinotruk HOWO series heavy-duty trucks. As a critical safety component in the truck‘s cab tilting mechanism, this single‑acting hydraulic cylinder converts hydraulic pressure into linear mechanical force, lifting the entire cab forward to provide unobstructed access to the engine compartment for routine maintenance, repairs, and component inspection. The cylinder is typically actuated through a manual hand pump or an electrically driven hydraulic pump, with the operator activating the system from a control lever located either inside the cab or at the exterior pump unit.
