APPLIES IN YOUR AREA. IF IT DOES NOT APPLY, THEN YOU MUST
MOUNT THE UNIT IN COMPLIANCE WITH YOUR LOCAL DOT
REGULATIONS.
NOTE: IF THE FENDERS ON THE TRUCK ARE WELL CONSTRUCTED,
THAT IS, HEAVILY GUSSETED AND BRACED, IT MAY BE POSSIBLE TO
UTILIZE THE FENDERS AS PART OF THE SUPPORT STRUCTURE FOR THE
ARM MOUNTING BRACKETS.
A.
Put the longest and highest container that is to be covered on the truck. This
container is used to determine the pivot point for the arms and to determine the
arm length. If your containers are not the same length, you may have to modify
this guideline to comply with the majority of containers you have.
B.
Measure the distance from the back side of the roller to the front side of the rear
door on the container. Dividing this measurement in half will give you a starting
point for locating the Arm Mounting Brackets (G 1531).
If the center line measurement obtained above falls over a fender, it is possible to
utilize the fender in determining the exact pivot point. If the centerline
measurement does not fall near a fender then you will have to construct some type
of TEMPORARY support for the Arm Mounting Bracket, while the exact pivot
point is found. Temporary support can take the form of tack welding the Arm
Mounting Bracket (G 1531) to the container itself or tack welding a plate to the
container, to lower the bracket down to its proper position and the tacking the
bracket to the plate.
In either case, proceed as follows: Tack weld -1- Arm Mounting Bracket to the
fender or to the temporary support, so that the front of the bracket (the front has
the bend on it) lines up with the measurement determined above.
Mount the Arm Mounting Bracket as low as possible without interfering with the
tires or the hoist cylinder(s). It is advisable to have the greatest included angle that
you can derive between the arm and an imaginary horizontal line thru the center
of the Arm Mounting Bracket in a front to rear plane.
C.
Insert -1- Bow Corner (G 2099) into an Arm and place the Arm onto the Arm
Mounting Bracket. Swing the Arm towards the gantry and adjust the bow in or
out so that it is approximately 2” to the rear of the bearing plate. Secure the bow
to the arm with clamps, and swing the arm thru its arc to the rear of the truck. The
bow, which will hold the rear section, should line up with the front edge of the
door on the container. If the bow goes past the rear of the container, the Arm
Mounting Bracket will have to be moved forward. If the bow falls short of the
rear of the container, move the Arm Mounting Bracket toward the rear of the
truck. Re-position the bracket if necessary and re-check as outlined above.
Once you are satisfied that the position of the Arm Mounting Bracket is correct,
carefully mark the exact location of the bracket on either the fender of the
temporary support. You are now ready to construct a support structure for the
Arm Mounting Bracket.
