The support cylinder assembly, identified by part number 672 167 40, serves as a component within the outrigger system of the Demag AC80-1 mobile crane. This hydraulic unit manages the extension and retraction of the crane supports, which are necessary to establish a stable and level platform for lifting tasks. By adjusting the position of these supports, the assembly helps distribute the weight of the crane and its load across the ground surface, assisting in the management of forces during operation.
This component is specifically configured for fitment on the Demag AC80-1 model. It integrates directly into the hydraulic circuit that controls the stabilization legs, allowing the operator to deploy or retract the outriggers as required for site setup. The assembly is designed to handle the hydraulic pressures associated with the stabilization functions of this crane class.
Support cylinders act as the primary interface between the crane chassis and the ground. They provide the mechanical force needed to level the machine on uneven terrain and maintain stability while the crane is under load. Proper operation of these hydraulic cylinders is necessary for the intended function of the outrigger system.
