To pick up bales that are placed "End
on", drive so that the inner arm of the
loading fork is against the inner edge of
the bale. The bale will then be loaded
onto the carrier in the same direction as it
was picked up.
3. Rotating pick up arm (hydraulic)
The carrier travels in the same direction
as the baler. Bales are approached "Side
on".
ROTATING PICK UP ARM OPERATION
The ADJUSTABLE FORK on the SLIDING
ARM should be set so the distance between
the forks with the squeeze cylinder fully
extended is about 6" (15 cm) wider than the
width of the bales you are loading.
The sequence valve attached to the rotate
cylinder is preset to open at 1800 psi. If the
bale falls out of the forks before rotating and
lifting operations are completed, either reduce
the space between the forks by moving the
ADJUSTABLE FORK in or increase the
opening pressure of the sequence valve. This
can be done by removing the cap and turning
the screw in. Be sure to replace the cap.
Lower BALE LIFT ARM. Drive forward until
FORKS are positioned around ends of bale
with the inside stationary fork as close as
possible to bale. Engage hydraulics. This will
start an automatic sequence. First oil flows to
the squeeze cylinder. When the squeeze
pressure reaches 1800 psi, the line to the
rotate and lift cylinder opens and the bale is
rotated and lifted into position.
Reverse the oil flow and the squeeze cylinder
opens dropping the bale onto the carrier. The
LIFT ARM then returns to the lowered
position ready to pick up the next bale. With a
little practice an operator can pick and load
bales "on the go".
