Extend cylinder for Terex RT555

The extend cylinder 7906531 serves as a primary hydraulic component within the boom system of the Terex RT555 rough-terrain crane. It converts hydraulic fluid pressure into linear force to extend or retract the telescopic boom sections, allowing the machine to reach specific working heights and radii required for lifting tasks. This cylinder is integrated directly into the boom assembly, where it manages the movement of the boom segments to maintain proper load positioning.

This part is specifically engineered for the Terex RT555 model. It operates by receiving pressurized hydraulic fluid from the crane main pump and control valves, which drives the internal piston and rod assembly to actuate the boom. Proper function of this hydraulic cylinder is necessary for the smooth operation of the telescopic boom system under load.
