3.
Position the rear hinge angle in the notch cut in Step 2. The rear hinge angle is 38 1/16" wide
and should be centered side to side in the notch as illustrated in Figure 3. Weld the rear hinge angle to
each of the truck chassis frame rails.
NOTE:
This hinge assembly is designed for a truck longsill spacing of 34" and is not
recommended for any other width.
NOTE:
The distance between the rear hinge shaft center and the saddle center is referred to as
the "M" dimension. In Table A, the "M" dimension for several dump angles are
tabulated.
NOTE
:
Moving the hoist rearward or forward along the truck frame will affect the hoist's
performance. A forward movement will reduce the dump angle and will increase
capacity while a rearward movement will increase the dump angle and reduce capacity.
NOTE:
If an obstruction can not be cleared by moving the hoist forward or rearward, the hoist
may be reverse mounted as shown in Figure 1.

Locate the hoist on the truck frame, making sure to center the hoist right and left, and to square
the hoist with the truck frame. This hoist is designed to rest on the truck frame as shown in
Figure 1. A small portion of the hoist extends below the truck frame level. The hoist may
have to be moved forward or rearward to avoid obstructions below the frame level.

Slide a lock collar onto each lifting shaft. Slide a lifting shaft with collar into each end of the
hoist lifting tube. See Figure 4.
