1.0 Considerations Before Installation
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 designed 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 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 Rubberized Undercoating).
- Load cells, bearing plates, brackets and hardware should 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 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.
1.1 Welding Specifications
Welding, metalworking and assembly should 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.
Important
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.
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.
WARNING
Always disconnect battery terminals before performing any welding.

Load Pin and Transducer Specification 3
2.0 Load Pin and Transducer Specification
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.

3.0 Roll Off Load Pin Installation
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.
Important
All load pin installations require lubrication facilities. Normally lubrication is provided through the central
pivot area.
OEM Roll Off pivots typically have existing lubrication fittings included in their pivots. Rice
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.

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 therear of the hoist chassis and maintain its position/alignment while the
pivot pins are being replaced.
3. Remove the bolt and washer from the outer collar on the pivot.
Note
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 into the frame and out the other side, removing the inside collar as well.
5. Remove the outer collar if still attached to the frame.
6. Using a power grinder or a wire brush, clean around thehole where the pivot was located, both sides of the
frame.
7. Grind the frame smooth to ensure a clean weld at load cell installation.
8. Remove any debris that is inside and around the holes of the chassis supports and the pivots.

Important
Important
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.

3.7 Final Installation
1. Reinstall the fenders.
2. Test the hoist to make sure none of the cables at risk of being pinched, stretched or cut when it is raised and
lowered.
3. Test the hoist to make sure the scale reads positively with applied weight. If positive weight is not
displayed, it is possible that the load pins or a load pin are not in the correct position and reading
backwards. Pin position can be changed by rotating 180 degrees.
