Boom Actuation: This is its core function. The boom cylinder converts hydraulic pressure from the excavator's pumps into powerful linear force (extension and retraction). This force directly raises and lowers the massive boom arm, which is the first and largest lever in the excavator's linkage.
Generating Breakout Force: The boom cylinder is the primary contributor to the machine's tremendous boom digging force (or breakout force). This is the force applied to tear through and lift heavy, compacted materials like rock, iron ore, or bank shot. The 395's immense power comes from the combination of its massive hydraulic pumps and the large bore diameter of its boom cylinders.
This 564-4924 boom cylinder is used for 390D 390F excavator.
