Place the SL-185 hoist assembly on the truck chassis. The truck chassis mounting
surface should be flat without any steps or protrusions. If necessary shim bars need to be
added to ensure a flat surface on which to support hoist. The truck chassis should meet
the following minimum specifications (See Figures A & B):
RBM for each frame channel: 600,000 in.-lb.
Total RBM: 1,200,000 in.-lb.
Minimum clear frame rail for mounting: 156" (See Fig. A)
Front Axle Cap: 8,000 lb. (Min)
Total Rear Axle Capacity: 14,000 lb. (Min)
CA Dim: 108" to 120" (120" preferred)
Note: The above specifications are a minimum requirement. It is the responsibility of the
owner/operator to ensure the completed chassis meets or exceeds all federal, state,
and local regulations. Also, the hoist should not be used to lift and haul any load
that exceeds the load rating of any of the individual components of the completed
chassis (tires, axles, suspension, etc.)
The clear frame dimension indicated in the picture above allows for the overall length of
the hoist plus 5 inches for cab clearance and rear light bar mounting. Extra frame length
may be needed to allow for mounting additional accessories (e.g. Cab Guard, Tarper,
Light Kit, etc.). For example, when mounting a light kit on a truck with a long CA,
check that the hoist and the light kit are positioned far enough back to eliminate any
interference between the fender and the light kit. You should also consider the final
weight distribution with regard to the bridge code when positioning the hoist.
