• 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 and 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 salts are used on road surfaces, under-body coating is
recommended (3M™ Underseal™ part number 3M-8883 Universal Rubb erized Undercoatin

consideration are:
g).
1.2.1 Welding Specifications
Welding, metalworking and assembly sh ould only be perfo rmed by qualifie d 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.
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.
2 LoadRunner™ Series Installation & Service Manual
Rice Lake Weighing Systems recommends removal of load cell after tack welding bearing plates in
position so that final welding is performed without load cell being subjected to excessive heat, weld
current, or cable damage.
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 wit h 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 four degrees, for the weight reading
degrees to be valid and accurate.
This manual provides instructions for the installation of straight frame dump trucks and “pup” dump trailers only.
For information on full frame or frame-less end dump or side dump trailers, please refer to the Rice Lake
Precision Loads manual (PN 115094).

Note
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 zerk which
must be supplied and installed by the system installer.
3.1 Installing the Load Pins
1. Remove the rear fenders from the truck, if required, to gain free and clear access to the pivots.
2. Use jacks or a forklift to support the rear of the dump bucket and maintain its position/alignment while the
pivot pins are being replaced.
3. Remove the bolt and washer from the collar/support on the pivot.
Removing pivot pins on some vehicles may be difficult if rust is present or if the hoist chassis pivot and the truck
chassis supports are out of alignment. If rust is an issue, use a penetrating lubricant and appropriate tools for
tapping the pivot pin out. Use a pry bar as a lever to assist with any misalignment problems to remove the
existing pivot pins.
4. Push the pivot pins out of the supports.
5. Mark the frame where the pivot supports are located, in an area that will not be affected by grinding the
frame smooth. This will assist in the location of the new supports.
6. Remove the supports from the frame of the truck.
7. Using a power grinder or a wire brush, clean the area where the supports were located, both sides of the
frame. Grind the frame smooth to ensure a clean weld for the support installation.
OEM Roll Off pivots typically have existing lubrication fittings included in their pivots. Rice

4.5 Configuration of Inclinometer Calibration
On dump truck and roll off applications, the load runner system uses the load
pins and hydraulic pressure transducer to determine a weight value. To achieve
the best accuracy, calibrate the system at the same incline that weight will be
read, with +/- 1-2°.
The Inclinometer setup screen shows both the body angle in a numeric value
and absolute angle (abs 0.0). For this application, use the level indicators,
which light up for every degree the body is raised.
The numeric value will indicate a negative value as the body is raised, which is
normal. The level indicators to the right will light up, 1° per circle.
The inclinometer function allows visual determination of the height of the body
to achieve an accurate weight value consistently.
1. Make sure the truck is on a level surface and the body is in the down
position.

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.

5.0 Service and Troubleshooting
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 test numbers to work with, the test numbers help locate a problem
source quickly. Scale meters are built with simple but effective internal system diagnostics programs that isolate
component performance.
With reference to onboar d scale ser vice and repair procedures that involve load pins, trunnions and air transducers,
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 that a properly serviced installation will provide
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 appropriate regulations of the U.S. Department of
Transportation (DOT), state and local regulations, the recommended standards and practices of the Society
of Automotive Engineers (SAE), standards of the American Welding Society (AWS), and the
recommendations of the truck, trailer and body, hoist and/or suspension manufacturer.
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.
There is no typical interval for scale calibration that can be universally specified. Instead, operators should keep
comparison data of onboard scale loads as compared to weights obtained from certified platform scales or premeasured loads. If this is not possible, six-month re-calibration intervals are recommended. See Section 4.7.
5.3 Sensor Maintenance
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 failur
