THEORY OF OPERATION - CONTINUED
MAST HYDRAULIC SYSTEM
Lift Cylinder. The lift cylinder is a ram-type cylinder that moves up by oil pressure and moves down by gravity. The
extended part of the cylinder is completely filled with oil.
Tilt Cylinders. Two double-acting tilt cylinders both extend and retract by hydraulic pressure. These cylinders control
the forward and backward tilt angle of the mast.
Side Shift Cylinder. A double-acting side shift cylinder controls the side shift of the forks and tophandler with respect
to the center line of the machine.
Side Tilt Cylinder. This double-acting cylinder rotates the forks and tophandler.
