Page 8: Lifting And Handling (Steel Deck)
SURVIVOR OTR Flattop Truck Scale 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. -
Page 9: Assemble Deck Modules
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. © Rice Lake Weighing Systems ● All Rights Reserved... -
Page 10: Place End Module A
SURVIVOR OTR Flattop Truck Scale 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. -
Page 11: Place And Attach Adjoining Modules B And C
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. © Rice Lake Weighing Systems ● All Rights Reserved... -
Page 12: Raise Deck And Level With Approaches
SURVIVOR OTR Flattop Truck Scale 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. -

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 © Rice Lake Weighing Systems ● All Rights Reserved... - Page 14 SURVIVOR OTR Flattop Truck Scale 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.

Page 15: Mount Block And Shim (Groutless) Installation (Option 1)
RLWS has a shim plate (PN 67292) available to level the scale. Do not exceed over 3/4'' of shims combined. Note If more is necessary, contact Rice Lake Weighing Systems for other options. 1. Apply anti-seize compound to threads of mount block bolts. - Page 16 SURVIVOR OTR Flattop Truck Scale 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.
- Page 17 14. Insert a bolt through the wire terminal on the loose end and thread the bolt into the hole on the baseplate. 15. Tighten the bolt securely with a wrench. Ground Strap Figure 4-11. Ground Strap © Rice Lake Weighing Systems ● All Rights Reserved...

Page 22: Recheck Link For Binding
SURVIVOR OTR Flattop Truck Scale Recheck Link for Binding Once the load cell cable is installed and wired, the concrete deck can be poured. 1. Install the access plates over each load cell location to prevent concrete from spilling into the load cell access cavities. 2. -
Page 23: Pour And Finish Concrete Deck
6. Clean concrete splatters from the painted frame members with a wet sponge before they dry, and before applying a liquid curing agent. 7. Apply liquid curing agent to complete concrete pour and finish (Section 6.3 on page 20). © Rice Lake Weighing Systems ● All Rights Reserved... -
Page 24: Moist-Cure Concrete Deck
SURVIVOR OTR Flattop Truck Scale Moist-Cure Concrete Deck For proper curing, the surface must be kept moist for seven days. If the top surface is allowed to dry out during this time, the finished surface is prone to spalling and surface cracking. Hot weather, full sun, and windy conditions all accelerate surface drying. -
Page 25: Connecting Electronic Equipment
On scales over 70' long with four or more modules, two or more junction boxes are necessary. Refer to assembly print or foundation plan for junction box location and homerun cable output. Note © Rice Lake Weighing Systems ● All Rights Reserved... -
Page 26: Electrical Ground Connections
SURVIVOR OTR Flattop Truck Scale Electrical Ground Connections Improper grounding systems on outdoor truck scales often cause corrupted data from ground-loop current IMPORTANT flows and costly lightning damage to electronics. Always strive for a single-point grounding system (Figure 7-3 on page 23). -
Page 27: Installing Transient Protection
Serial communications may also require transient protection to fully protect entire system. A TP-232 DC Transient Note Protection is suitable protection for serial communications lines. In addition, printers, remote displays, and other devices connected to serial communications should be protected with AC transient protection. © Rice Lake Weighing Systems ● All Rights Reserved... -
Page 28: Trimming And Calibration
SURVIVOR OTR Flattop Truck Scale Trimming and Calibration The following section provides descriptions and procedures for load cell trimming, scale calibration and serial tag placement. Overview and Equipment Required Load Cell Trimming Individual load cell signal trimming (equalizing the signal output from each load cell) must be done first along each side of the scale so all cells on a side have equal signal output. - Page 29 Step 1 – Step 5 until all four cells on Side 1 read within 0.1% of each other. 9. Repeat Step 1 – Step 8 for load cells 5-8 on Side 2 of the scale. © Rice Lake Weighing Systems ● All Rights Reserved...

Page 30: Trimming Paired Sections
SURVIVOR OTR Flattop Truck Scale Trimming Paired Sections Now that all individual load cells are trimmed for equal output, pairs of load cells on opposite sides of the scale must be trimmed for equal sectional output. This process is called section trimming. 1. -
Page 31: Calibration With Test Weights
The serial tag on an OTR truck scale is found at the end of the scale near the SURVIVOR logo. A duplicate tag is placed inside of the junction box pocket. Figure 8-7. Serial Tag Placement © Rice Lake Weighing Systems ● All Rights Reserved... -
Page 32: Load Cell Replacement
SURVIVOR OTR Flattop Truck Scale Load Cell Replacement Use the following steps to replace load cells in the OTR truck scale: 1. Position jack on the concrete foundation beneath one of the weighbridge main frame members close to the load cell mount. -
Page 33: Preventative Maintenance
The junction box should be opened and checked for any moisture or corrosion on internal circuitry. The PreVent™ filter should be changed on an annual basis. Desiccant packs inside the box should be examined and exchanged on an annual basis. Cable connectors should be inspected and checked for tight fittings. © Rice Lake Weighing Systems ● All Rights Reserved... -
Page 34: Grounding
SURVIVOR OTR Flattop Truck Scale 10.5 Grounding All ground connections are connected to a single ground point. At minimum, a 10-gauge wire should run from a lug on the scale to the single-point ground.
