Elevator and Air Supply
The regulated air supply for the elevator cylinders and blow-off flows to a
3-position elevator control valve. The valve controls the flow of air to the
elevator cylinders. The elevator control valve has three positions:
Up
,
Down
, and
Neutral
.
S
In the
Up
position, air enters the bottom of the left cylinder and flows
through the lower crossover tube to the right cylinder. Air above the
pistons is vented. The air pressure forces the cylinder pistons
upward, which raises the follower plate and pump.
S
In the
Down
position, air enters the top of the left cylinder and flows
through the upper crossover tube to the top of the right cylinder. Air
below the pistons is vented. The air pressure forces the cylinder
pistons downward, which lowers the follower plate and pump.
S
In the
Neutral
position, there is no pressure to the frame cylinders.
The follower plate should remain stationary, since the air pressure to
both sides of the piston is sealed.
NOTE:
The
Neutral
position is not a locked and secured position. The
follower plate may drift downward over time.
The blow-off feature routes air under the follower plate during the removal of
an empty container. The blow-off assembly connects to the blow-off port.
Pressing and holding the push button on the blow-off valve forces air under
the follower plate. The air pressure forces the container off of the follower
plate.
