The boom cylinder is a primary hydraulic actuator responsible for controlling the raising and lowering of the excavator's boom, which is the main arm attached to the upper structure of the machine.
This cylinder is fundamental to nearly every task an excavator performs. It provides the powerful lifting force needed to position the stick, bucket, and any attachments, as well as to manipulate loads.
This 259-0840 boom cylinder is used for 315D 318D excavator.
