BOOM COMPONENT HYDRAULIC SYSTEM

The boom components controlled by the boom control manifold valve are, 1st/2nd boom cylinder, 3rd boom cylinder,
telescope cylinder, jib cylinder, platform rotator, and platform leveling cylinders.

The boom components are controlled by an hydraulic manifold valve equipped with one maximum pressure valve, one
proportional valve and an ON-OFF valve for each aerial part movement.
