Preventing platform movement

The platform may move during weighing although the rubber feet tend to minimise this. Three techniques can
be used to prevent movement. Either a wooden or steel beam can be fixed in front of and behind the load bars,
the rubber feet can be pinned or anchored to the foundation or the load bar assembly can be chained.
Beams
1 Fit the load bars to the platform. See Installing MP load bars on page 5.
2 Align a beam of wood or steel channel section so that it is parallel with the front load bar (or the platform if
the feet are not visible) with 5 mm (
3 Fix the beam to the pad using masonry anchors or similar.
4 Use the same technique at the rear load bar.
5 Test the installation. See Testing on page 10.
Pinning or anchoring
The load bars may be pinned with 1 or 2 pins at each end of each load bar.
If anchoring the load bars into place, each load bar must be anchored at all 4 mounting holes.
The following is a suggested method to pin or anchor the load bars in place. It may be varied depending upon
the locating holes in the rubber feet being visible and accessible.
1 Fit the load bars to the platform. See Installing MP load bars on page 5.
2 Place the completed load bar assembly in the required position.
3 Carefully unbolt one load bar from the platform. Carefully lift the platform clear leaving the load bar on the
concrete pad.
4 Using the load bar left on the concrete pad, drill the mounting holes in the foundation. To do this either
spot the holes through the rubber feet, remove the load bar and drill the holes, or drill through the holes in
each rubber foot. Drill 2 holes for pinning (either the inside or outside holes at each end of the load bar,
whichever are easiest to access) or drill all 4 holes if anchoring the load bar.
5 Pinning may be done by fitting masonry anchors and leaving the nuts off the top, or by dropping a Ø12 mm
( 1 / ") rod into the hole, which projects through the hole in the foot. Anchoring requires fitting a masonry
2
anchor for each hole in the rubber foot (4 anchors per load bar).
6 Pin or the anchor the first load bar. If anchoring into place, use washers between the nut and the rubber
foot. Tighten the anchors evenly but do not over-tighten which will squash the rubber foot excessively.

3 / ") clearance between the rubber feet (or platform) and the beam.
