Hydraulic Cylinder for Crane Support Legs

Crane support leg hydraulic cylinder is an important part of the crane outrigger system. It adopts the hydraulic transmission principle and drives the outriggers to extend and retract through liquid pressure to achieve stable support of the crane. The hydraulic cylinder is mainly composed of cylinder barrel, piston, seal and guide sleeve. The hydraulic oil enters the cylinder barrel through the pipeline, pushing the piston to reciprocate in the cylinder barrel, thereby realizing the extension and retraction of the outrigger.
