Introduction

This manual is intended for use by technicians responsible for installing and servicing the RoughDeck®CS.

Authorized distributors and their employees can view or download this manual from the Rice Lake

Weighing Systems distributor site at www.ricelake.com.

CAUTION

Site Consideration: The opening of the V-Top coil cradle option runs parallel with the load cell pocket

cover plate. See Figure 2-3 on page 18

Package includes: Assembled weighbridge module and weighbridge fasteners; load cells; load cell mounts with

leveling bolts and anchor bolts; junction box; homerun cable to indicator (20' long).

1.0 Installation

The general assembly order is summarized below:

1. Set deck module into position on setting blocks.

2. Install load cell mounts in pockets and anchor bolts in baseplates.

3. Run cabling and connect electrical wiring to J-box.

4. Connect indicator and peripheral devices.

1.1 Recommended Equipment and Tools (Steel Deck)

• Crane with a minimum 5000 lb. capacity

• Four chains or cables (8' minimum length each) with hooks or clevises

• 3/4" rotary hammer drill

• 3/4" x 24" masonry carbide bit

• One low-profile 4-ton bottle jack

• 3" minimum setting blocks

• Torque wrench to 100 ft-lb

• Socket wrenches to 1 1/2" (drive compatible with torque wrench)

• Box end wrenches to 1 1/4"

• Open end wrench set (7/16" – 1 1/4")

• 4' bubble level

• Small torpedo level

• Hammers, maul, pry bar

• Hand tools for pulling and connecting electrical wiring

1.2 Lifting and Handling (Steel Deck)

Deck modules are lifted using four chains or cables attached to the four lifting straps mounted on the top of the

weighbridge. The lifting straps provide balanced lifting of the modules.

WARNING

Note A set of lifting lugs are provided with the scale.

Lifting straps must always be inserted into the top of the scale. Lifting should always occur

withthetopplatefacingupandtheliftingstrapssecurelyattachedthroughthenutsweldedto

the bottom side of the top plate. Lifting from the bottom of the plate could cause nuts to break

loose and the scale to fall.

1.3 Temporary Setting Blocks

Most installers use setting blocks that are approximately 3" high for the initial placement and connecting of the

deck module. Use leveling bolts in base plate to level the scale. Setting blocks are only used in the corners of the

module where the load cell mounts are installed.

Note

Note When placing module on setting blocks, place blocks in locations close to, but not at, the pocket (to allow

room for mount).

It is important to consider the orientation of the scale if using the V-Top coil cradle option. The V-Top coil

cradle runs parallel with the load cell pocket cover plate. See Figure 2-3 on page 2.

Load Cell Mount Installation 17

2.0 Load Cell Mount Installation

Load cell mount components (baseplate, mount blocks, anchor bolts, link, load cell, and upper mount blocks) are

shipped in the hardware box and need to be assembled while in the load cell pocket. Remove the printed load cell

Certificate of Conformance (CC) forms (included with load cells) and store them in a safe place for future

reference.

The following sections contain step-by-step instructions on mount installation, including the baseplate, load cells,

upper mount blocks, ground straps, and anchor bolts.

2.1 Install Baseplate and Load Cell

Use the following steps for installing the mount baseplate and load cell in the load cell mount pockets:

1. Remove load cell mount components from the packing box and position one set at each mount location.

Figure 2-1. Baseplate

2. Remove load cell pocket covers.

3. Working with the baseplate first, lower baseplate through pocket opening and onto concrete foundation.

4. Place the load cell link over the end of the cell and install load cell/link assembly onto the top of the

baseplate.

5. Place the load link on top of the load cell and the upper mount block on top of the load link.

6. Place the load cell and load link assembly onto the two stands of the base stand and screw in the load cell

mounting bolts (finger tight). The loose bolts allow freer movement for better weighing accuracy.

7. Adjust the load link so it is vertical and centered side to side (in a balanced condition). If the load link is

not vertical and centered side to side, adjust the base stand.

8. Apply anti-seize compound to threads of load cell bolts before installing. Torque load cell bolts 55 ft-lb.

2.2 Mount Block and Grout Installation

Use the following steps to install mount blocks and baseplate grout.

Note It is important to consider the orientation of the scale if using the V-Top coil cradle option. The V-Top coil

cradle runs parallel with the load cell pocket cover plate. See Figure 2-3

18 RoughDeck HE AutoLift

9. Adjust leveling bolts until radius of block comes in contact with rocker link radius.

10. Jack the weigh module and remove setting blocks.

11. Slowly lower the weigh module until it rests on the load cell links.

Note

Note Aftertheweighmoduleisloweredintofinalposition,checkeachloadcellmountassemblytoensurethatthe

link is plumb and that there is no binding or misalignment.

12. Use an industrial hammer drill to drill a 3/4" hole into the concrete at least 6" deep on one side of the

mount frame.

13. Drill a second anchor bolt hole on the opposite side of the mount frame.

14. Each mount requires two anchor bolts to prevent longitudinal motion of the baseplate. Anchor bolts (7" x

3/4") with expansion heads are supplied with the scale.

15. Insert bolts into holes drilled in foundation.

16. Install one washer and one nut on each anchor bolt. Place a driver pipe on top of the anchor bolt and use the

long punch to seat anchor bolts against baseplate.

Do not apply excessive force to the anchor bolts-- bending of the baseplate could occur.

When installing anchor bolts, make sure that there is adequate bolt length to extend into the concrete

foundation.

17. Attach one end of the ground strap to the upper block.

18. Insert a bolt through the wire terminal on the loose end and thread the bolt into the hole on the baseplate.

Tighten the bolt securely with a wrench.

19. Pour 9000 PSI, non-shrinking, epoxy or cement grout under and around the baseplate. A funnel with a

long tube can be used to pour grout under and around the baseplate while working from above the access

hole.

20. Grout should be allowed to set for at least 24 hours before removing the wooden forms.

21. After grout has hardened, tighten anchor bolt nuts.

Load Cell Wiring 19

3.0 Load Cell Wiring

Before the weigh module wiring can be completed, all load cell cables have to be routed through the conduit

beginning at the load cell outlet. Use the following steps to route load cell cables through conduit to the J-box:

1. Before routing load cell cables, mark each load cell cable at the end to help identify each load cell.

2. Working from the J-box corner, insert a fish tape or similar tool and pull each load cell cable through the

rigid conduit until all excess cable is taken in.

Pocket 2 Conduit

Pocket 3 Conduit

Figure 3-1. J-box location

3. Wire each load cell to the J-box terminal strip in accordance with the wiring code contained in the

Certificate of Conformance.

4. Cable should not be routed near heat sources greater than 400°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 sit in

water.

5. 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.

6. 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.

Note Flexible conduit and conduit adapters are an optional item and not included with the standard setup.

7. Connect cables for load cells to the summing board in the junction box according to the guide shown

below and the labels on the terminal strips of the junction box. To verify the wiring scheme, see the

certification shipped with each load cell.

8. For better performance, use positive and negative remote sense lines if the wiring running from the

junction box to the indicator is longer than 25 feet
