3.0 Installation
The following sections explain how to properly install the RoughDeck FXB flexure base scale.
3.1 Site Preparation
Do not locate the scale where overweight loads would have to maneuver to avoid crossing the platform. Use the
following guidelines for site preparation:
• For scales not meant for washdown environments, avoid areas where water may cause damage.
• The interface cable between the scale and the indicator must be protected against crushing, cutting, or
moisture damage. Protect the cable by running it in conduit. Do not allow the cable to lay in water.
For proper operation, the scale must be level within a 1/4". Choose a site where the floor is close to this standard to
avoid excessive shimming, or modify the floor at the chosen site to meet this standard. After a site is selected:
1. Use hook-end chains to move the scale base to it permanent location. Location should be level and have a
solid and stable foundation. An unstable location causes inaccurate or fluctuating weight readings.
2. Verify that the scale base rests firmly on the floor on all four corner gussets. Shim between each gusset and
floor as required to attain a firm and stable mounting.
3.2 Assembly
1. Cut bands holding the load cell package from lever arm and remove the load cell with wire rope.
Load cell support frame
3/4" or 1" spacer (see
note on page 15)
Inner (top) nut
Nose iron
Outer (bottom) nut)
Wire rope
Note
CAUTION The load cell is a delicate device and can be damaged if dropped, twisted when mounting, or shook loaded.
2. Insert a block under the primary lever so it fits snugly. Remove the shipping bolt and spacer. The shipping
bolt is placed between the load cell support frame and the nose iron (in place of load cell) during shipping
(see Figure 3-1).
3. The load cell is shipped with wire rope. Remove the outer nut from the load cell wire rope.
4. Screw the inner nut on the wire rope flush with the top of the threads.
5. Remove the load cell mounting bolt from the top of the cell.
6. Screw the short threaded end of the wire rope through the bottom of the load cell until it’s flush with the
top.
The 3/4" spacer is used beginning with the 30" x 30" 2000 lb model and those higher, with the exception of the 48" x
48" 20000 lb models which use a 1" spacer.
7. Carefully lower the load cell into position at an angle so the wire rope threaded rod end goes through the
hole of the nose iron first. If used, position the spacer between the load cell support frame and the load cell.
