Crane luffing hydraulic cylinder is a hydraulic device used to change the elevation angle of the crane boom. It is mainly used to adjust the length and angle of the crane boom to meet different work requirements. It is usually installed in the luffing mechanism of the crane and is powered by the hydraulic system to achieve the luffing operation of the boom.
Crane luffing hydraulic cylinder function: control the luffing angle and adjust the distance between the mast and the main engine. Realizing the up and down pitching rotation of the outrigger is the main driving force for lifting.
