2.0 Installation
The modular sections of the OTR series truck scale are shipped pre-assembled and ready to be placed into position on
temporary setting blocks using a crane.
The general assembly order is summarized below:
• Set deck modules into position on setting blocks
• Install load cell mounts in pockets and anchor bolts in base plates
• Run cabling and connect electrical wiring to junction box
• Connect indicator and peripheral devices
2.1 Foundation Slab Cure Period
Standard concrete reaches full strength after a 28-day curing period. At seven days, standard concrete reaches approximately
75% of its maximum strength and can handle moderate loads.
Please refer to ACI318 for additional information regarding concrete curing requirements, and consult the concrete vendor to
discuss curing requirements based upon the mix used specifically for the site. Loading of a slab before it reaches 75% of its
maximum strength may cause permanent structural damage.
2.2 Assembly Time Estimates
When scheduling installation for a typical three-module, 70' truck scale, plan for a two-hour minimum crane rental to place the
modules into position. A two-man crew, aided by a crane operator, can unload modules from the truck and place them into
position in approximately one hour.
Mount and load cell installation requires approximately three to four hours. Electrical wiring is run through conduit and can be
done in approximately two to three hours.
For concrete deck scales, a concrete crew of three or four can normally pour, finish, and seal-cure the concrete deck surface of
a 70' scale in two to three hours. Final wiring connections can normally be completed the same day while the concrete is curing.
These estimated times may vary.
Recommended Equipment and Tools (Steel Deck)
• Crane with a minimum 8000 lb* capacity
• Four chains or cables (8' minimum length each) with hooks or clevises
• 3/4'' rotary hammer drill
• 3/4'' x 24'' carbide masonry bit
• One low-profile 4-ton bottle jack
• 5 1/2'' setting blocks
• Various thickness shims to level scale
• Torque wrench to 100 ft-lb
• Socket wrenches to 1 1/2'' (drive compatible with torque wrench)
• Box end wrenches to 1 1/4''
• Open end wrench set (7/16'' – 1 1/4'')
• 4' bubble level
• Small torpedo level
• Hammers, maul, pry bar
• Hand tools for pulling and connecting electrical wiring
*Typical single module weight of 70' x 11', three-module truck scale.

2.3 Lifting and Handling (Steel Deck)
Deck modules are lifted using four chains or cables attached to the four lift lugs mounted on the top of the weighbridge
(Figure 2-1). The lift lugs provide balanced lifting of the modules.
Figure 2-1. Lifting Deck Modules
Loads may disengage from crane scale hook and shackle or lifting eye if proper procedures are not followed.
A falling load may cause serious injury or death.
Never lift more than the crane scale’s assigned Working Load Limit (WLL) rating.
A set of lifting lugs are provided with the scale and shipped on the last module loaded on the truck at the factory.
2.4 Temporary Setting Blocks
When the deck is level with the approaches, the finished scale has a 5 3/4'' clearance between the bottom of the weighbridge
and the concrete foundation. Most installers use setting blocks that are approximately 5 1/2'' high for the initial placement and
connecting of the deck modules. Shims are used to level the scale and raise it flush with the approach bulkhead. Setting blocks
are only used in the corners of the modules where the load cell mounts are installed. The corners that do not have load cell
mount locations do not require setting blocks.
Figure 2-2. Setting Block Measurements (Steel Deck) – 18'' Foundation Profile
When placing modules on setting blocks, place blocks close to the pocket (to allow room for mount).

3.0 Assemble Deck Modules
Deck modules are designated as A, B or C. All two-module scales have an A and C module, while longer scales with more
than two modules have one or more B modules.
The modules are marked as A, B, or C on the end of each module for identification during placement and assembly.
Figure 3-1. Deck Modules
A Module
The A module is an end module and is the first to be placed on setting blocks. The left end is a straight end which is positioned
next to the vertical wall of the concrete approach. The right end of the A module contains two pin-connection receptacles that
are used to accept the two module-support pins located on the B module.
B Module
The B module is a center module, it has two module-support pins on the left end and two pin-connection receptacles on the
right end. The two module-support pins of module B are inserted into the two pin-connection receptacles of module A.
The pin-connection receptacles of module B accept the module-support pins from another B module or a C module.
C Module
The C module is an end module and the last one placed on setting blocks. The two module-support pins are designed to attach
to either an A module for a two-module installation or to a B module for an installation that has more than two modules.
The opposite end of the C module is a straight end and is positioned next to the vertical wall of the concrete approach.
Figure 3-2. Weigh Modules Ready for Removal and Installation
Modules have been stacked on the truck for shipping in the order that they are installed. The A module is the top module,
followed by B modules and the C module is the bottom module.

3.1 Place End Module A
Before lifting the A module from the truck, place four 5 1/2'' temporary setting blocks on the concrete foundation at each of the
four corners. Also re-measure the overall distance between approaches. The OTR is undersized 1 1/2''. When installed in a 70'
opening, there will be a 3/4'' gap between the approaches and the scale. Minor adjustments can be made when setting the first
module to equally space the scale between approaches.
Depending on foundation and clean out requirements, a different size of setting blocks may be required. Assembly
instruction references an 18'' approach profile for a 5 3/4'' clean out. Adjust as needed for specific application needs.
Figure 3-3. Module Positioned on Temporary Setting Blocks
Position each setting block so that it does not interfere with installation of the load cell mounts.
Place module A with the straight end 3/4'' from the concrete bulkhead. With 5 1/2'' setting blocks, the deck surface is 1/4'' - 3/8''
from the top of the concrete approach. Square this module with the approach and check that the side-to-side dimensions are
the same.
Figure 3-4. Setting Modules in Place
Before installing the B module, check that no debris has fallen into the two pin-connection receptacles.

3.2 Place and Attach Adjoining Modules B and C
In a scale with more than two modules, the next module is a B module (Figure 3-5). If the scale has only two modules, it is a C
module. Place two 5 1/2'' setting blocks at the corners opposite of the module support pins (load cell mount locations) to support
the B module.
Figure 3-5. Module B Installation
Place the B module so the module-support pins engage with the pin-connection receptacles of the A module and the opposite
end rests on the two setting blocks.
Figure 3-6. Pin and Receptacle Interface
If the pins do not seat squarely in the receptacles, raise the module slightly and reset the module again.
When the B module is in place, remove the cables or chains from the module and install any other B modules or the C module
in a similar manner.
The C module is installed in the same way that the B module was installed. The end of the C module should be approximately
3/4'' from the approach bulkhead.
The weigh module setup is now complete and the scale is ready to be leveled.

3.3 Raise Deck and Level with Approaches
Use the following steps to raise and level the weigh modules with the concrete approach:
1. Beginning at the approach (left) end of the A module, raise the scale deck using low-profile hydraulic jacks.
2. Add shims on the setting blocks until the deck surface is level with the approach.
3. Move to the opposite end of the A module and raise and level this end.
Figure 3-7. Leveling Deck with Approaches
4. When all four corners of the A module are leveled, ensure the module is square with the approach and that it has a
3/4'' end clearance from the concrete bulkhead.
5. Move to the B module and continue leveling the weighbridge by leveling the load cell mount end of the B module.
6. Raise, level, and shim any other B modules if they are installed.
7. When the B module or modules are done, continue by leveling the C module in the same manner.
Figure 3-8. Check Weighbridge for Level
8. When all modules are leveled and shimmed, check the edge alignment with a string line or a level along one side of
the main beam.
9. Check the module support pins to ensure they are firmly seated in the pin-connection receptacles.
10. Ensure the weighbridge end clearance is within specified requirements.
11. The deck is now at its final position and ready for load cell mount installation.
This procedure could be accomplished while installing the shims if transit is used to level scale (Section 3.3).

4.0 Load Cell Mount Installation
Load cell mount components (baseplate, mount blocks, anchor bolts, link, load cell, flexcable, and upper mount blocks) are
shipped in the hardware box and need to be assembled while in the load cell pocket. Remove the printed load cell Certificate of
Conformance (CC) forms (included with load cells) and store them in a safe place for future reference.
The following sections contain step-by-step instructions on mount installation, including the baseplate, load cells, upper mount
blocks (shim and grout), ground straps, and anchor bolts.
4.1 Install Baseplate and Load Cell
Use the following steps for installing the mount baseplate and load cell in the load cell mount pockets.
1. Remove load cell mount components from the packing box and position one set at each mount location.
Figure 4-1. Baseplate
2. Lower baseplate through pocket opening and onto concrete foundation.
3. Remove cover plate from the 90° fitting included with conduit assembly.
4. Insert the load cell cable through the exposed 90° fitting.
Figure 4-2. Insert Load Cell Cable Through 90° Fitting

5. Thread the exposed 90° fitting to the load cell, making sure the cable does not twist.
6. Insert cable through second half of fitting and conduit, then re-install cover plate to 90° fitting.
• This method prevents connections from being twisted off inside the load cell
Figure 4-3. Installing 90° Fitting to Load Cell
7. Place the load cell link over the end of the cell and install the assembly onto the top of the baseplate.
8. Apply anti-seize compound to threads of load cell bolts before installing. Torque load cell bolts 50 – 75 ft-lb.
Figure 4-4. Load cell Access
9. Position flex cable so that a loop can be made in it and the end can be attached to the rigid conduit.

4.2 Mount Block and Shim (Groutless) Installation (Option 1)
Use the following procedure for installing mount blocks and shims for leveling:
RLWS has a shim plate (PN 67292) available to level the scale. Do not exceed over 3/4'' of shims combined.
If more is necessary, contact Rice Lake Weighing Systems for other options.
1. Apply anti-seize compound to threads of mount block bolts.
Figure 4-5. Example Shim Dimensions
2. Apply grease to link contact points where the link touches the load cell and both radius blocks.
3. Install one bolt through welded block into upper mount block.
4. Add or remove shims until radius of block comes in contact with rocker link radius.
Figure 4-6. Shim Installation (Option 1)
5. Install second bolt assembly through blocks and shims, then torque to 55 ft-lb.
• Repeat process on all load cell pockets
Position the slotted end of shim towards shorter end of load cell pocket. This allows more room to work when adding
or removing shims.

6. Ensure the link for any binding or misalignment and the link is plumb in respect to the upper blocks
• Check that the link is centered between the side of the link and the upper blocks
If needed, tap the edge of the baseplate with a hammer to make minor adjustments in alignment.
Figure 4-7. Recheck Link for Binding
7. Jack the weigh module and remove the setting blocks.
8. Slowly lower the weigh module until it rests on the load cell links.
9. Use an industrial hammer drill to drill a 3/4'' hole into the concrete at least 6'' deep on one side of the baseplate.

10. Drill a second anchor bolt hole on the opposite side of the baseplate. Each mount requires two anchor bolts to prevent
longitudinal motion of the baseplate.
• Anchor bolts (7'' x 3/4'') with expansion heads are supplied with the scale.

4.3 Mount Block and Grout Installation (Option 2)
Use the following steps to install mount blocks and baseplate grout:
• Adjust leveling bolts until radius of block comes in contact with rocker link radius
• Jack the weigh module and remove setting blocks
• Slowly lower the weigh module until it rests on the load cell links
After the weigh module is lowered into final position, check each load cell mount assembly to ensure that the link is
plumb and that there is no binding or misalignment.
1. Use an industrial hammer drill to drill a 3/4'' hole into the concrete at least 6'' deep on one side of the mount frame
(Figure 4-8 on page 12).
2. Drill a second anchor bolt hole on the opposite side of the baseplate. Each mount requires two anchor bolts to prevent
longitudinal motion of the baseplate (Figure 4-9 on page 12).
• Anchor bolts (7'' x 3/4'') with expansion heads are supplied with the scale
3. Insert bolts into holes drilled in foundation.
4. Install one washer and one nut on each anchor bolt. Place a driver pipe on top of the anchor bolt and use the long
punch to seat anchor bolts against baseplate (Figure 4-10 on page 13).
Do not apply excessive force to the anchor bolts-- bending of the baseplate could occur.
When installing anchor bolts, make sure that there is adequate bolt length to extend into the concrete foundation.

5. Attach one end of the ground strap to the upper block.
6. Insert a bolt through the wire terminal on the loose end and thread the bolt into the hole on the baseplate.
7. Tighten the bolt securely with a wrench (Figure 4-11 on page 13).
8. Erect temporary wooden forms around each baseplate and pour 9000 PSI, non-shrinking, epoxy or cement grout into
the forms beneath the baseplate (Figure 4-12). A funnel with a long tube can be used to pour grout into the forms while
working from above the access hole.
Figure 4-13. Completed Baseplate Grouting
9. After pouring the grout, tap the form several times with a hammer to remove any air voids beneath the baseplate.
• It must have even support from continuous grout contact
10. Remove the temporary wooden forms when the grout is set (Figure 4-13).
• Grout should be allowed to set for at least 24-hours before removing the wooden forms
11. Tighten anchor bolt nuts after the grout has hardened.

5.0 Load Cell Wiring
Electrical conduit is pre-installed at the factory and only needs to be connected between the modules and from the modules to
the junction box. Following conduit work, load cell cables are routed through each conduit from the load cells to the junction
box. All load cell cabling used for this installation comes in the shipping container. The layout pattern for the electrical conduit
on a three module truck scale installation is shown in Figure 5-1.
