2. There are two types of mount brackets used on the Model SL-412 hoist as indicated in Fig.
B and Pg. 5-7. They are the angle brackets (Pt. No 89H51) and the mid brackets (Pt. No.
89H46). Locate the mount brackets on the side of the hoist as indicated in Fig. B. These
dimensions are flexible because of possible interference with chassis components. Also
allow for mounting the control valve assembly and the hydraulic tank. 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, D & E). 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 21/32"
diameter holes required and attach
the brackets to the truck chassis
with the 5/8" diameter bolts,
washers, and locking hex nuts
provided. Torque to 110 ft.lb.
3. Bolt the mount brackets to the hoist
main frame as indicated on Fig. C,
D and E. 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.
