6.7 Tilt cylinder (Fig 6.8)
The tilt cylinder is of double-acting type. Each truck has two cylinders which are
installed on two sides of the mast, their cylinder base are connected with frame with pins
while their piston rod ends are connected with the outer mast channels.
The tilt cylinder assembly consists of piston, piston rod, cylinder body, cylinder base,
guide sleeve and seals. The piston, welded to the piston rod, is fitted with two Yx-rings
and one wear ring on its circumference. A bushing press-fitted to the inner side of the
guide sleeve supports the piston rod .The guide sleeve is fitted with dust seal, snap ring,
Yx-ring and O-ring to prevent oil leakage and keep dust off. Fitted with them, the guide
sleeve is screwed into the cylinder body.
When the tilt lever is pushed forward, the high-pressure oil enters into the cylinder
body from the cylinder tail, moving the piston forward and causing the mast to tilt forward
until 6 degree. When the tilt lever is pulled backward, high-pressure oil enters into the
cylinder body from the guide sleeve and moves the piston backward, tilting the mast
backward until 11 degrees.
