2.0 Installation
2.1 Overview
Standard installation of an assembled scale consists of the following steps:
1. Select a site
2. Install pit
3. Unpack scale
4. Adjust scale feet
5. Connect pneumatic controls and cylinders
6. Connect cable from junction box to indicator
7. Calibrate the unit
2.2 Site Preparation
The scale must not be loaded beyond its capacity, even momentarily. Do not select a site where overweight loads
would have to maneuver to avoid crossing the platform. Avoid areas where the scale might receive damaging side
impacts from wheels or forklift tines, or shock damage from falling objects.
The interface cable between the scale and the indicator must be protected against crushing, cutting, or moisture
damage. If the chosen site has such potential dangers, use some method of protection, such as running the cable in
conduit.
In operation, the scale must be level within
1
/
4
".
2.3 Unpacking
The scale is shipped with the following components to install:
• Four foot assemblies for corners
• Cable ties and miscellaneous hardware
Remove all packing material and inspect scale for visible damage caused during shipment.
All RoughDeck models have threaded holes in opposite corners of the deck to allow installation of eyebolts for use
when lifting the scale with chains from a spreader bar. Use
1

" eyebolts.
Lift the scale only with a properly designed spreader bar as shown in Figure 2-1.
Lifting force must be vertical to avoid bending the eye bolts.
Eye bolts must always be inserted into the top of the scale. Lifting should always occur with
the top plate facing up and the eye bolts securely attached through the nuts welded to 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.
