dimensions are flexible because of possible interference with chassis components. You
should consult the truck chassis supplier for any limitations regarding drilling mount holes in
the truck chassis frame rails. Typically, the holes must be at least 2 3/4" from the top of the
truck chassis rails (reference Fig. C & Fig. D). Once the locations of the mount brackets
have been determined, use the mount brackets as a template for marking the mounting
holes in the truck chassis frame rails. Drill the 17/32" diameter holes required and attach the
brackets to the truck chassis with the 1/2" diameter bolts, washers, and locking hex nuts
provided. Torque to 110
ft.lb.
3. Weld the mount brackets
to the hoist main frame as
indicated on Fig. C and
Fig. D. You may need to
modify the mount brackets
or add shim plates to allow
for variances in the width
of the truck chassis as well
as to allow for top rivets,
stepped channels, etc.
NOTE:
PRIOR TO ANY WELDING, CONSULT
THE TRUCK MANUFACTURERFOR
ANY SPECIAL PRECAUTIONS THAT
MAY NEED TO BE TAKEN.
TYPICALLY, THE BATTERIES MUST
BE DISCONNECTED AND THE
GROUND LEAD FROM THE WELDER
SHOULD BE CONNECTED AS
CLOSE AS POSSIBLE TO THE PART
BEING WELDED TO AVOID THE
POSSIBILITY OF ARCHING ACROSS
BEARINGS, GEARS, ETC.
THE HOIST MAIN FRAME IS MADE
FROM HIGH STRENGTH LOW
ALLOY STEEL. USE AN
APPROPRIATE WELDING PROCESS.
