Jackingcylinder
In a fire engine, the jacking cylinder is usually installed at the connection point between the boom and the chassis, at the connection joint of multiple sections of the boom, or at the connection point between the working platform and the last section of the boom. It is the core hydraulic actuating component for achieving the lifting of the boom and the elevation of the platform, and its performance directly affects the working height, carrying capacity and operational stability of the fire engine.
