READ AND UNDERSTAND THESE INSTRUCTIONS COMPLETELY BEFORE
BEGINNING THE INSTALLATION. USE THESE INSTRUCTIONS WITH THE
DRAWINGS INCLUDED. UNPACK, IDENTIFY AND FAMILIARIZE YOURSELF
WITH THE VARIOUS COMPONENTS OF THE UNIT.
THIS SYSTEM IS DESIGNED TO BE USED WITH CONTAINERS THAT HEVE A
32' MAXIMUM OVERALL INSTALLATION LENGTH.
THIS SYSTEM FEATURES FIXED ARMS, THIS MEANS THAT FINISHED
COVERED POSITIONS MUST SHARE A COMMON ARC.
PRIOR TO INSTALLING THE FLOW DIVERTER, WITH INTEGRAL PRESSURE
RELIEF VALVE AND COVER CONTROL VALVE INTO YOUR TRUCKS
HYDRAULIC SYSTEM, WE RECOMMEND THAT YOU CHECK WITH THE
HOIST MANUFACTURER FOR POSSIBLE WARRANTY IMPLICATIONS.
1. MOUNTING THE GANTRY AND ROLL ASSEMBLY
A. Pick a suitable stationary forward position on the trailer directly ahead of the container stop
position, to mount the GANTRY and ROLL ASSEMBLY. Clear away or re-route any hoses,
cable, etc. that may interfere with mounting the GANTRY to the trailer. The GANTRY can be
mounted to the trailer using the -2- CHASSIS MOUNTING ANGLES provided. These can be
bolted to the chassis using grade 8 hardware and then welding the GANTRY on top of these
angles or these angles can be welded to existing plates that are already bolted to the trailer.
Another method is to utilize brackets, etc. that are already bolted to the trailer, and weld a piece
of channel or tube to the existing brackets, across the width of the trailer and then mount the
gantry on top of the channel. In either case, allow enough clearance between the rearward
portion of the GANTRY LEGS and the front of the container. This will provide clearance for the
ROLL ASSEMBLY as it moves up and down. Square the GANTRY to the hoist and level from
side to side as well as being plumb vertically. A GOOD WAY TO MAKE CERTAIN THE
GANTRY IS SQUARE TO THE HOIST IS TO CLAMP A STRAIGHTEDGE ACROSS THE
INSIDE OF THE "J" HOOKS AND MEASURE FROM THIS TO THE GANTRY LEGS.
Once the GANTRY is located and welded securely at the bottom, add front to rear gussets to
stabilize the GANTRY and strengthen the mounting.
B. Place the ROLL ASSEMBLY on top of the GANTRY and install using -4- 1/2-13 hex nuts
and lock washers provided. Install the 36" stroke cylinder onto the clevis eye pads on the
GANTRY and ROLL ASSEMBLY using the clevis pins and cotters provided.
NOTE: THE PORTS ON THE CYLINDER SHOULD FACE TO THE LEFT OR
DRIVERS SIDE WHEN VIEWED FROM THE REAR.
