"HYDRAULIC SYSTEM"
The hydraulic system supplied with a given hoist manufactured by TBEI-Rugby is made up of components
(pump, valves, reservoir, hoses, cylinder, etc.) that are designated to be compatible with each other.
WARNING: If you substitute hydraulic components, it is your responsibility to BE SURE they are compatible
with the other components supplied by TBEI-Rugby. Incompatible hydraulic components may
cause failure of the hoist that, in turn, could damage the vehicle, damage other property, and cause
human injury or death.
All TBEI-Rugby's liability and warranty for a given hoist will be voided, if it is determined by TBEI-Rugby, that
substituted hydraulic components were incompatible with those supplied by TBEI-Rugby.
Several hoist parameters are given in the following table, these parameters are given as a general guide. To
ensure component compatibility, consult TBEI-Rugby.
WARNING: Adjusting the hydraulic pressure to more than the recommended setting may cause the hoist to fail
during the dumping of a load. This could cause damage, serious injury, or death. Never adjust the
pressure on your own. Consult the manufacturer if the hydraulic pressure is in question. Have
only a qualified person set the hydraulic pressure. Never adjust the pressure to more than the
recommended amount.
NOTE: A manual for the hydraulic system is supplied separate from this manual. Refer to the hydraulic
system manual for details on the installation and operation of the hydraulic system.

"WARNINGS"
WARNING: Installing or operating this hoist without first understanding the proper installation and operation
procedures can lead to serious injury or death. Always read and understand fully all installation
and operation manuals before installing or operating this equipment.
WARNING: Welding, oxy-fuel cutting, or grinding sparks can cause fuel to ignite that in turn can lead to injury
or death. Always take adequate steps to avoid ignition of fuel from fuel tanks when welding,
grinding, or oxy-fuel cutting during equipment installation.
WARNING: Heat from the truck's exhaust system can cause hydraulic component failure and may lead to a fire
that could cause injury or death. Always install equipment in locations where heat from the
exhaust system will not damage any hydraulic component.
WARNING: Being under a raised body can result in serious injury or death should the body unexpectedly
descend. Never position yourself or allow others to position themselves under a loaded body.
Always prop the unloaded body up using the body prop or body props supplied. Remember
body props are to be used only on an unloaded body. When two props are provided, both props
must be used.
WARNING: Malfunctioning equipment can cause property damage, injury or death. Always have faulty
equipment repaired before continuing its use. Consult the manufacturer if required.
WARNING: Overloading of a body can cause vehicle or body component damage or an accident which may
cause injury or death. Never exceed the gross vehicle weight (GVW) or the gross axle weight
(GAW) rating of your vehicle.
WARNING: The inadvertent shorting of the vehicle's electrical supply can cause a fire or equipment damage
that could lead to injury or death. Always disconnect the vehicle battery prior to installing,
servicing, or repairing the power unit.
WARNING: Damage to brake lines during equipment installation, or installing bolts or equipment in such a
way that the line will rub and become damaged can lead to brake failure which can cause an
accident and can lead to severe injury or death. Always take adequate steps to prevent brake line
damage during installation and isolate brake lines from installed equipment.
WARNING: Connecting the hoist to a hydraulic system with more pressure (psi) or flow (gpm) than is
recommended by the hoist manufacturer can cause the hoist to fail during the dumping of a load.
This could lead to damage, serious injury, or death. Be sure you have the correct pressure and
flow.

"INSTALLATION INSTRUCTIONS"
1. If a LR-26C hoist is to be mounted in this sub-frame, first bolt the two flat brackets to the sub-frame as
shown in Figure 1A LR-26C. Next, position the hoist saddle so that it lines up with the flat edge of the
flat bracket. This will give a mounting distance of 90.50” from the centerline of the hoist saddle shaft to
the centerline of the sub-frame rear hinge.
If a LR-623 or LR-2355 hoist is to be mounted in this sub-frame, first bolt the two flat brackets to the
sub-frame as shown in Figure 1B LR-623 or 1D LR-2355. Next, position the hoist saddle so that it lines
up with the flat edge of the flat bracket. This will give a mounting distance of 95.50” from the centerline
of the hoist saddle shaft to the centerline of the sub-frame rear hinge.
If a LR-28A hoist is to be mounted in this sub-frame, first bolt the two flat brackets to the sub-frame as
shown in Figure 1C LR-28A. Next, position the hoist saddle so that it lines up with the flat edge of the
flat bracket. This will give a mounting distance of 109.81” from the centerline of the hoist saddle shaft to
the centerline of the sub-frame rear hinge.
Ensure that the hoist and sub-frame are positioned squarely on the truck frame before performing any
welding. Mark the location for the rear hinge. This location should be immediately behind a truck cross
member, approximately 32" behind the center of the rear axle on single axle trucks. Refer to Figure 1 and
the charts for the specific hoist model you are installing.
WARNING: Failure to position the hoist at the proper sub-frame mounting point could cause the hoist to
function improperly, leading to possible hoist, body or equipment damage.
WARNING: Failure to position the hoist at the proper sub-frame mounting point could cause the hoist to

2. Attach the sub-frame flat brackets to the sub-frame using 1/2 x 4" bolts, lock washers, and nuts. Refer
to Figure 2.
3. Attach the sub-frame guide plates to the sub-frame using 1/2 x 4" bolts, lock washers, and nuts. The
guide plate should be installed in the next available hole forward of the flat bracket for the LR-26C,
LR-623, or LR-2355. It should be installed in the next available hole rearward of the flat bracket for
LR-28A. Refer to Figure 1.
4. With the hoist in position, attach the sub-frame to the hoist by welding each of the two sub-frame flat
brackets to each of the two hoist saddle brackets. Refer to Figure 2.
5. Position a hoist mounting angle, with three holes, under the saddle bracket located on each side of the
hoist. Secure each large mounting angle to the truck frame by drilling three 17/32" dia. holes and
bolting the mounting angle to the truck frame. Use 1/2 x 1-1/2" bolts, lock washers, and nuts. Finally,
weld each mounting angle to its respective saddle bracket. Refer to Figure 2.
6. Cut off the excess truck frame behind the sub-frame rear hinge. Weld the sub-frame rear hinge to the
truck frame on both sides.
NOTE: The sub-frame model hoists are designed to set on the truck frame, as shown in Figure 1. If a
cross member or some other obstacle in the truck frame interferes with the rear end of the
hoist, the rear end of the hoist can be raised to clear the obstacle. The raising of the hoist rear
end will not affect the lifting capacity, but raising the rear end of the hoist will raise the
mounting height, ie. larger truck body long sills will be required or some cross sill notching
will have to be done.
7. Install each of two lifting shaft as illustrated in Figure 4.

Model LR-26C, LR-623, LR-28A, & LR-2355 Sub-Frame Hoist Installation and Operation Manual

8. Position truck body on sub-frame.
NOTE: A clearance of at least 2" is required between the truck cab and the closest point on the
truck body.
9. Attach each rear hinge bracket to a long beam by welding all edges where the rear hinge
bracket contacts the long beam.
WARNING: The saddle tube is oblong, allowing the hoist to slide front to back. This is part of the anti-
kickup design. Before performing the next step, the hoist must be pushed back as far as
possible as shown in Figure 3. Failure to do so will cause the "anti-kickup device" to
function improperly, causing damage to the hoist, truck body, and/or other truck
components.
10. Position a lifting shaft assembly next to each channel long beam. Two 3/8" x 2.5" x 12"
flats are supplied with each hoist. Weld a lift shaft to each channel long beam. Refer to
Figure 5. With the lift shafts secured, slide the lock collars against the lifting tube and
lock them by tightening the set screws. Refer to Figure 4.
11. Install all grease fittings. For grease fitting locations in the hoist, refer to Figure 10. Torque each
grease fitting to 70 in-lb. Grease all grease fittings on both the hoist and the rear hinge.
12. Install the body prop. Refer to the "BODY PROP" section of this manual.
13. Install the hydraulic system. Cycle the hoist several times to rid the hydraulic circuit of air.

"BODY PROP"
NOTE: In order to comply with paragraph 10 of Federal Regulation #1926.601, all TBEI-Rugby hoists
will be sold with one body prop. It is the responsibility of the installer to determine whether one
body prop is sufficient. The following information will help in making that determination.
The body prop is designed for use only when the body is empty. The purpose of the body prop is
to hold an empty body in the raised position when performing maintenance or inspection on the
hoist, body, or any component that requires working under an empty body.
Some applications may require 2 or more body props to support the empty body. To determine
how many body props your application requires, refer to the following information.
WARNING: Being under a raised body can result in serious injury or death should the body inadvertently
descend. Never position yourself or allow others to position themselves under a loaded body.
Always prop the unloaded body up using the body prop/s supplied. Remember, body props are
to be used only on an unloaded body. When two props are provided, both props must be used.
WARNING: Do not use body prop to support a loaded body!
WARNING: Do not perform maintenance under a raised body without first blocking the empty body up with
the body prop/s.
WARNING: Do not use a body prop that is bent or otherwise damaged. A damaged body prop will have a
reduced holding capacity, and may break when used to hold up the body. This could cause serious
injury or death. Replace a damaged body prop before using it.
WARNING: Be sure to install the body prop according to the “INSTALLATION OF BODY PROP” section
of this manual.
The following is a step by step procedure to determine how many body props are required for this application.
1. The TBEI-Rugby Part Number 03 0703 body prop is to be used with this hoist. Determine if this is the
body prop you have by referring to Figure 6.
2. Determine the "P" value referring to Figure 7. The "P" value is the horizontal distance between the rear
hinge and the prop.

Model LR-26C, LR-623, LR-28A, & LR-2355 Sub-Frame Hoist Installation and Operation Manual
Stock No. 1657499
Page 14 of 25
3. Determine the "X" value referring to Figure 7. The "X" value is the horizontal distance between the body
center of gravity and the rear hinge when the body is empty and down. Be sure to include any items
attached to the body such as toolboxes or other structures when determining the center of gravity.
4. On the left side of Chart 1, pick the "P" value for your application. On the top of the same chart, pick the
"X" value for your application. Below the "X" value and to the right of the "P" value is listed an amount
of weight. This represents the maximum weight that the body can weigh and be supported by only one
body prop. If the body weights more than the amount listed, 2 body props will be required. Contact TBEI-
Rugby to order another body prop.
NOTE: If the body weighs more than 2 times the amount listed, another type of body prop with more
weight capacity will be required, as 2 body props will not support this empty body.

EXAMPLE: Using a 12' body that has an empty weight of 6,000 pounds. Body is installed with a 18"
overhang. The prop is located 84" forward of the rear hinge. Assume the center of gravity is
72" from the rear of the body. Subtract the overhang to get X=54". Using P=84-89, X=49-60,
the maximum body weight is 5,900 pounds. This application needs 2 body props. Remember,
this is an example only, and in no way means that this hoist is or is not acceptable to use in
this application.

"INSTALLATION OF BODY PROP"
NOTE: The following steps are to be used as a guideline when installing the body prop. Since trucks will
vary according to their design it is not possible to be specific about every aspect of the body prop
installation.
1. Once the TBEI-Rugby hoist has been installed, raise the hoist up and temporarily block the body up.
Position the prop assembly against the truck frame as illustrated in Figure 7.
2. Fasten the body prop assembly base to the truck frame.
3. Position and fasten the prop hanger to the truck frame. Hanger must be installed so that when the body is
down the body prop leg will not bounce out of the hanger.
4. Position and weld the prop cup on the body as illustrated in Figure 8.
NOTE: To raise and lower body prop, see the "OPERATION OF BODY PROP" section of this
manual.

"LUBRICATION"
IMPORTANT: All grease fittings should be greased at least twice annually. Refer to Figure 12 for grease
fitting locations. Failure to grease hoist will result in hoist failure. Hoist failure due to lack of
grease is not covered by the warranty.
IMPORTANT: Refer to installation and operation manual of the hydraulic system for hydraulic system
lubrication instructions.
1. Grease all of the grease fittings in the hoist frame itself. Apply grease until excess grease can be seen
coming out the ends of the tubes. Refer to Figure 10 for grease fitting locations. Replace any missing or
broken grease fittings.
2. Grease the two grease fittings in the truck rear hinge.
3. Check oil level in the pump reservoir every time the oil is changed in the truck engine. REMEMBER
