2. DETERMINING THE PIVOT POINT AND INSTALLING THE MOUNTING
THE MOUNTING BRACKET ASSEMBLIES AND ARMS MUST BE MOUNTED TO A
FABRICATED STRUCTURE THAT IS BOLTED TO THE TRAILER FRAME. THIS
STRUCTURE MUST EXTEND OUTWARD FROM THE FRAME TO ALLOW FOR THE
WIDEST WIDTH CONTAINER THAT WILL BE CARRIED ON THE TRAILER, WHETHER
OR NOT THE CONTAINER IS TO BE COVERED. (ex. self contained compactor containers)
THE OUTSIDE WIDTH FROM THE GREASE FITTING TO THE GREASE FITTING
CANNOT BE MORE THAN 108" TO BE IN COMPLIANCE WITH THE FEDERAL D.O.T.
AND REGULATIONS PROMULGATED THEREUNDER. SOME STATES HAVE
REQUIREMENTS FOR STATE AND LOCAL ROADS THAT DIFFER FROM THE
FEDERAL D.O.T. REGULATIONS. PRIOR TO INSTALLATION, YOU SHOULD CHECK
WITH YOUR STATE AND LOCAL D.O.T. TO ASCERTAIN WHAT STANDARDS APPLY
IN YOUR AREA. IF THEY DO NOT COMPLY WITH THE FEDERAL D.O.T., YOU MUST
MOUNT THE SYSTEM IN COMPLIANCE WITH YOUR STATE AND LOCAL
REGULATIONS.
PIONEERS INSTRUCTIONS ARE PREMISED ON 102" MAXIMUM TRAILER WIDTH
ALLOWED BY FEDERAL D.O.T. REGULATIONS.
A. Supplied with your system to make installation easier are -4- CHASSIS MOUNTING TUBE
ASSEMBLIES. These are made longer in both directions than you may need so you can cut
them to fit your installation. To determine how far out from the trailer frame you must be with
the MOUNTING TUBES, measure the outside width of your frame and subtract this
measurement from 106 1/4". Divide this measurement by 2 to determine how far out from the
chassis on each side the MOUNTING TUBES will protrude to support the MOUNTING
BRACKET ASSEMBLIES in their proper location. From this measurement subtract the
thickness of the "fish plates" that may already be already bolted to the frame or need to be
attached to the frame where the MOUNTING TUBES will be welded.
EXAMPLE: Frame width (outside to outside) = 33 1/2"
106 1/4" - 33 1/2" = 72 3/4"
72 3/4" divided by 2 = 36 3/8"
"fish plates" are 1/2" thick
36 3/8" - 1/2" = 35 7/8"
Horizontal portion of CHASSIS MOUNTING TUBES needs to be 35 7/8" long.
B. Put the longest and highest container that will be covered on the trailer. Using two tape
measures, place one end of one tape on the top rear of the container, and the end of the second
tape on the arm rest (provided), then stretch the tapes out diagonally toward the center of the
trailer and move along the bottom of the rubrail of the container toward the middle, until you
