1.0 Introduction
The installation should be planned by a qualified structural engineer.
Each installation is unique, this manual is meant to serve as a general guideline for installation.
Manuals and additional resources are available from the Rice Lake Weighing
Systems website at www.ricelake.com
Warranty information can be found on the website at www.ricelake.com/warranties
The RoughDeck CC Caster Cargo Scale has a 20,000 lb capacity with a powder coat surface
for durability. Load and unload the caster deck scale in all directions with 360 degree swivel
casters (108 Kalpar Casters model DL55014893).
The EZ Mount kits provide an extremely accurate method for weighing medium and large
capacity structures that are subject to large thermal expansion/contraction or vibration forces.
The design uses a double ended shear beam load cell (700 Ω bridge) and transmits the load
with a sliding pin on the load-bearing groove of the cell. This design is very effective in
providing for thermal expansion/contraction with little friction.
Figure 1-1. Thermal Expansion
In the majority of applications, the assemblies are self-checking and held captive with no need
for check or stay rods, making this mount a good choice for areas with frequent seismic activity.
The sliding pin design eases load cell installation and replacement without the need to raise the
structure a large amount.
The RoughDeck CC uses four stainless steel EZ Mount 1 weigh modules (Section 2.2 on page 4)
containing 10,000 lb stainless steel IP67 load cells (RL70000SS).
The RoughDeck CC also utilizes a JB4SS TuffSeal NEMA Type 4X stainless steel signal trim
junction box. The TuffSeal junction box can be placed in any of the corners of the caster deck
(Section 4.2 on page 8) and accessed through any of the 4 removable deck panels along with
the load cells and mounts.

1.1 Safety
Safety Signal Definitions:
Indicates an imminently hazardous situation that, if not avoided, will result in
death or serious injury. Includes hazards that are exposed when guards are
removed.
Indicates a potentially hazardous situation that, if not avoided could result in
serious injury or death. Includes hazards that are exposed when guards are
removed.
Indicates a potentially hazardous situation that, if not avoided, could result in
minor or moderate injury.
Indicates information about procedures that, if not observed, could result in
damage to equipment or corruption to and loss of data.
General Safety
Do not operate or work on this equipment unless this manual has been read and
all instructions are understood. Contact any Rice Lake Weighing Systems
dealer for replacement manuals.
Failure to heed may result in serious injury or death.
Do not use for purposes other than weight measurement.
Do not use any load-bearing component that is worn beyond 5% of the original dimension.
Do not use this product if any of the components are cracked.
Do not exceed the rated load limit of the unit.
Do not make alterations or modifications to the unit.
Do not use without the deck completely assembled.
Do not place fingers into slots or possible pinch points.

2.0 Mechanical Installation
This section provides an overview of mechanical installation information.
2.1 General Installation Guidelines
The RoughDeck CC system uses four EZ mounts. EZ mounts come assembled to the mount
risers with wooden blocks to keep the load cell from being loaded during shipping.
Figure 2-1. EZ Mount Assemblies
The mounting surface for the mounts must be level within ±0.5°.
If the mounting surfaces are not level, use shims and/or grout to level the mount.
If possible, check that the mount is level when the structure is fully loaded because excessive
deflections in legs and supporting structures may cause additional side forces, which affect
accuracy. Deflection of the mounts top or base plate due to loading should not exceed ±0.5°.
The load on each mount assembly should vary by no more than 20%.
Add shims where necessary to achieve correct load distribution.
During installation, avoid overload damage to the load cells.

2.2 Mount Installation
Secure an EZ Mount assembly to the riser mount plate in each corner of the caster deck. The
access panel top plate and corner caster plate need to be removed to access the mounting
holes to secure the EZ Mount assemblies.
Figure 2-2. EZ Mount Assembly Installation
EZ Mount Orientation
Position EZ Mount assemblies so the load cell cables are positioned on the inside.
Figure 2-3. Load Cell Orientation
The arrow on the load cell should point in the direction of the load.

Secure the EZ Mount Base Plate
Verify that there is no initial misalignment and that the load cells are in the center of the hole in
the top plate loading bracket. Relocate if necessary.
Attach the base plates to the foundation using suitable anchors for concrete or by bolting or
welding to a steel structure.
Verify that the base plates are no more than ±0.5° out of level. Shim if necessary and
fully tighten mounting bolts.
Verify bolts securing the load cell to the base plate are tight. Only torque load cell
bolts to 20 foot-pounds. This allows the double-ended load cell to flex under load.
If surrounding equipment is frequently steam cleaned, or if the load cell is subjected to direct
washdown, a protective shroud for the weighing assembly is recommended.
Proper drainage is necessary so the weighing assembly is not standing in water. All support
points should be equally stiff so that they deflect by the same amount as the structure is loaded.

3.0 Load Cell Wiring
This section provides an overview of load cell wiring information.
1. Route the load cell cables so they will not be damaged or cut. Cable should not be routed
near heat sources greater than 150°F. Do not shorten any load cell cable. The load cell is
temperature compensated with the supplied length of cable. Cutting the cable will affect
temperature compensation. Coil and protect excess cable so it will not be mechanically
damaged or be sitting in water.
2. Provide a drip loop in all cables so that water or other liquids will not run directly down the
cables onto either the load cells or the junction box.
Figure 3-1. Drip Loop
If conduit protection is necessary against mechanical or rodent damage to the load
cell cables, use flexible conduit and conduit adapters at the load cells.
Conduit can also provide protection against moisture ingress into the load cell.
3. Connect cables for RL70000SS load cells to the summing board in the junction box
according to Table 3-1 and the labels on terminal strips of the junction box.
To verify the wiring scheme, see the certification shipped with each load cell.
