1.0 Considerations Before Installation
WARNING
Important
WARNING
Failure to observe these recommendations and instructions could result in a hazardous
operating condition.
This manual is intended to provide information for the mounting of Onboard Weighing Systems sensors in a
variety of applications. In applying the installation procedures, which follow, some fundamental precautions and
recommendations must be observed by the installer:
• Rice Lake Weighing Systems’ Onboard Scales are design
ed for applications covering a broad range of
vehicle types. Things to take into consideration are:
- Significant variations in mountings
- Variations in load sensor models
- Specifications
- System configurations
• Installation procedures are similar for both new vehicle mountings
and retro-fit mountings. When doing a
retro-fit mounting, ensure that all vehicle structures are free from cracks, excessive wear, corrosion,
alignment problems, etc. that could affect safety and scale performance.
• Load cells, load cell bearing plates, mounting brackets an
d load cell hardware should be painted upon
installation to help protect the installation from corrosion. Industry appropriate, quality enamel paint is
recommended.
- For environments where high concentrations of sa
lts are used on road surfaces, under-body coating is
recommended (3M™ Underseal™ part number 3M-8883 Universal Rubb erized Undercoating).
- Load cells, bearing plates, brackets and hardware shou
ld be periodically inspected for any evidence of
rust or corrosion. If areas of corrosion are present, they should be cleaned with a wire brush and
re-painted or undercoated.
- Load cell connectors must be connected or capped during painting or undercoating.
• The instructions outlined herein are designed to
ensure that a correct installation will provide maximum
safety, optimum system performance and accuracy, a long operating life, and reasonable installation costs. It
is required that the installer comply with all guidelines and material specifications outlined in this manual,
with special emphasis on detail and inspection of work.
• Installation must comply with appropriate
regulations of the U.S. Department of Transport ation (DOT), state
and local regulations, the recommended standards and practices of the Society of Automotive Engineers
(SAE), standards of the American W elding Society (AWS), and the recommendations of the truck, trailer and
body, hoist and/or suspension manufacturer.
1.1 Welding Specifications
Welding, metalworking and assembly shou ld only be performed by qualified personnel experienced in welding on
vehicle body structures and sub frames. Only welding equipment of the highest quality should be used in the
welding of load cell bearing plates. When welding, use procedures that ensure high quality welds. Over-welding
may result in distortion and damage, while under welding may not develop adequate strength.
Rice Lake Weighing Systems recommends removal of load cell after tack welding bearing plates in
position so that final welding is performed without load ce
current, or cable damage.
If welding with load cells in position, the installer must ensure that electrical current cannot flow through the load
cell. All load cell terminals must be shorted together. Attach the ground strap directly to the vehicle frame member
to which the bearing plates will be welded. Never weld directly to a load cell.
Always disconnect battery terminals before performing any welding.

The Rice Lake Roll Off and Dump Truck kits are typically LIFT-TO-WEIGH KITS. This means that with the hoist
in the relaxed state (on the chassis), no weight reading is available. The hoist needs to be elevated to a position
showing the correct angle on the in-cab digital display unit, approximately 4 degrees, for the weight reading
degrees to be valid and accurate.

Load pins supplied are custom sized to fit the specific hinge and ram brackets of the vehicle. The LoadRunner Roll
Off system is compatible with Galbreath, Accurate and Ruddco. Installation requires removal of existing pins, and
replacements of these pins with Rice Lake load pins and collars.
All load pin installations require lubrication facilities. Normally lubrication is provided through the central
pivot area.
Lake pivots are furnished with drilled and tapped holes for the insertion of a standard lube zirk which
must be supplied and installed by the system installer.
OEM Roll Off pivots typically have existing lubrication fittings included in their pivots. Rice

See Figure 2-2 and 2-3 for load pin specifications and load direction.
10. T o install the collar kit, place collar on the load pin aligning the holes and secure with bolt. Pin should go in
from the top and be vertical. Use a small square to ensure the bolt is precisely vertical.

11. Tack weld the collar to the frame to hold in place.
DO NOT overheat the load pin when tack welding. This may damage the load pin. Do not exceed 140° F.
12. Remove the load pin from the frame.
Load pin should be easily removed by hand. If not, use a wood block (or similar material) to cushion the
load pin, and tap lightly to remove.
Do NOT strike the load pin directly, it may cause damage to the load pin.
13.
Skip-weld the collar to frame with four welds of 1 inch each, is adequate. However if the installer prefers,
the entire collar can be welded in place. Allow collar to cool before proceeding to next step. Ensure there
are no weld remnants inside the collar or pivots. Remove any such residuals.

If the indicator will be installed in the cab, choose an area that is easily visible to the driver. A mounting bracket is
provided.
When running cable to the indicator, use existing access hole if available, if not, a hole will need to be
drilled in the cab. Insert a grommet to protect wiring.
Do not allow cable jacket to contact bare metal edges.

4.7 Calibration
Calibration requires the use of a truck scale in order to calibrate the system. First determine the empty vehicle
weight or tare weight of the truck. Once the tare and zero calibration are performed, load the vehicle as close to its
legal maximum limit as possible to determine the span or net weight value used for calibration.
4.7.1 Calculating the SPAN (Net Weight)
1. To determine actual TARE weight, drive the empty vehicle onto a truck scale and note the total weight.

WARNING
5.1 System Maintenance
This section of the manual is intended to assist the user with techniques for system maintenance and
troubleshooting. Maintenance of the onboard scale can be done quickly and needs to be done at regular intervals.
For service issues make sure you have original

component performance.

some fundamental precautions and recommendations must be observed by servicing personnel.
Failure to observe these recommendations and instructions could result in a hazardous operating
condition.
• Servicing personnel must ensure that all vehicle structures are free from cracks, excessive wear, corrosion,
alignment problems, etc. that can affect safety and scale performance.
• The instructions outlined herein are designed to ensure
maximum safety, optimum system performance and accuracy, for a long operating life. It is therefore
extremely necessary that the installer comply with all guidelines and material specifications outlined in this
manual, with special emphasis on detail and inspection of work.
• Service and repair work must be in compliance with ap

5.2 Calibration
System calibration needs to be performed at the time of original scale installation. Rice Lake Weighing Systems
recommends that scale calibration be repeated about one month after original scale installation to adjust for any
mechanical influences that "seat" a new scale.

5.3.1 Load Pins
For hinge load pins, thorough pin lubrication is critical to proper scale performance . Ensure all load pins used in
roll-off and other pin applications are always well-lubricated.
5.3.2 Visual Inspection
At the end of each day, service personnel should perform visual inspections that look for:
• Signs of wear or "polishing"
• Signs of weld cracking or failure
• Evidence of excessive corrosion
• Evidence of potential chassis
• Body runner or support structure cracking or bending

5.4 Cables and Connectors
5.4.1 Cables
Inspect for any loosening of cables that might result in exposure to damage. Repair by adding more cable ties to
tighten up the cable run.
5.4.2 Connections
Rice Lake We ighing Systems uses special connectors which do not corrode and can withstand extremely cold
conditions. When aluminum connectors are present, especially in environments with high humidity or ro ad salts,
the connectors should be periodically cleaned and protected with plumbers tape. If a connector is severely
corroded, contact Rice Lake Weighing Systems for replacement information.
