Capacity Charts
The Capacity Charts (Figure 2, 3, 4, 5) are to be used as a reference when determining
capacity based on overhang.
NOTE: Approximately 10% additional capacity can be attained on an SR-4016 or SR-
4016B application if sub-frame and hoist are installed at 45°. A sub-frame modification
kit can be ordered from Rugby Mfg. if this installation is desired. Refer to the 45°
Application Sub-frame Modification section of this manual for additional information
and instructions.

General Safety
Hydraulic System
The hydraulic system supplied with an SR-series hoist manufactured
by Rugby Manufacturing Co. is made up of components (pump, valves,
reservoir, hoses, cylinder, etc.) that are designed to be compatible with
each other. Several different types of pump and hydraulic components are
available to power the SR-series hoists. Refer to the pump and hydraulic
component Installation and Operation Manual for more information.
If hydraulic components are substituted, it is the installer’s
responsibility to be sure they are compatible with the components supplied
by Rugby Manufacturing Co. Incompatible hydraulic components may
cause failure of the hoist which in turn could damage the truck, damage
other property, and cause human injury or death. Rugby Manufacturing
Company’s liability and warranty for a given hoist will be voided if it is
determined by Rugby Manufacturing Co. that substituted hydraulic
components were used that were incompatible with those supplied by
Rugby Manufacturing Co.
Figure 6: Torque Values

Bouncing or jerking of the hoist is to be avoided as it may
result in component failure, injury or death.
Unlatch tailgate prior to elevating a loaded dump body as
excessive forces on the rear of the dump body may result in
component failure.
Overloading of a truck can cause truck component damage,
injury or death. Never exceed the gross vehicle weight
(GVW) or gross axle weight (GAW) rating of your vehicle.
Do not operate the hoist until bystanders are free & clear of
the hoist and body.
Connecting the hoist to a hydraulic system with more
pressure (psi) or flow (gpm) than is recommended can lead
to damage, serious injury, or death.
Do not raise or drive a raised body against another object.
Doing so could result in equipment or property damage,
injury or death.

Installation
Body Prop Installation
A body prop & required hardware is supplied with every SR-series hoist package. For
instructions on how to raise and lower the body prop, refer to the Operation section of
this manual.
1. Insert the body prop into the body prop bracket (Figure 8).
2. Fasten the body prop to the body prop bracket using the supplied hardware.
3. Lower the body prop to the down position & align with slot until the body prop
rests against the top of the holder.
The body prop is only to be used to prop an unloaded body.
Serious injury or death can occur if the body prop is
misused.

inches extend past the tube on each side. (Figure 9.)
2. Position the hoist into the subframe by aligning each end of the saddle shaft into
the subframe brackets.
3. Secure the saddle shaft to the sub-frame with the provided hardware as shown in
Figure 10. Refer to Figure 6 for torque guidelines.

4. Position the provided 3/8” spacers under each sub-frame rail as far forward as
possible. Secure to rail by welding as shown. (Figure 11)
NOTE: Optional 12” or 24” bolt-on sub-frame extensions can be installed to convert the
9’ subframe to a 10’ or 11’ as required. For optional 45° dump angle applications, refer
to the 45° Application Sub-frame Modification section.
