Mounting Instructions
CAUTION
:
Verify lifting and support devices can support the hoist, sub frame,
and dump body combined weight before picking up the assembly.
The hoist, sub
-
frame and dump body are normally shipped assembled and
ready to install on a truck frame
-
see Figure 4. Truck manufacturers recommend
that the sub
-
frame does not contact the top of the frame. A gap can be estab-
lished by attaching
1/4”
thick wooden strips on top of the frame or installing a
spacer layer of adhesive backed, high strength neoprene rubber on top of the
frame. However, solid connections between the truck frame and the sub
-
frame
are required at the location where the hoist pins to the sub
-
frame and at the rear
of the frame. When mounting with a
1/4”
gap, the steel spacers supplied with
the kit need to be
installed between
the truck frame
and the sub
-
frame
at the hoist mount
location
-
see Detail
A. This spacer can
be eliminated if the
sub
-
frame is
mounted directly
on top of the truck frame with no space between the two.
1.
Set the assembly on top of the frame or spacer and position it a minimum of
3.5”
from the cab as shown above in Figure 4. Always make sure there is a
solid connection between the sub
-
frame and the truck frame at the rear in
the dump body pivot area and the hoist mount area shown in detail
“
A
”.
If the
rear pivot centerline extends beyond the rear of the frame, an angle iron
brace or similar structure can be welded across the back of the frame to sup-
port the pivot.
2.
Position the sub
-
frame mounting brackets along the sides of the frame in an
area where the brackets do not interfere with existing frame bolts or hard-
ware
-
see Figure 5. Flipping the brackets or moving to alternate holes drilled
in the sub
-
frame
usually eliminates interference. However, additional holes can
Make sure there is solid contact between the frame and sub
-
frame at the rear mount.
