7 Gently lower the platform onto the first load bar and confirm the second load bar is still in the correct
position by bolting the platform or crate onto the load bars.
8 Unbolt the second load bar and gently remove the assembly without disturbing the position of the second
load bar.
9 Drill the mounting holes for the second load bar and fit the pins or anchors as for the first load bar.
10 Gently lower the platform onto the load bars and check that the platform mounting holes line up with those
in the load bars. If not, then the load bars may need to be shifted slightly or the platform mounting holes
should be drilled out to provide a good fit of the platform or crate upon the load bars. Ensure that the
platform does NOT rock as it rests upon the load bars. If necessary, fit spacers under the load bars so that
the platform or crate is level and true upon the load bars. Time taken to get this correct will save a lot of
time and effort when commissioning the installation.
11 Bolt the platform to the load bars. Check periodically for movement and re-tighten if necessary.
12 Test the installation. See Testing on page 10.
Chaining (cattle crate, crush or squeeze chute)
Follow these additional steps for cattle crates, crushes and squeeze chutes.
Load bars under cattle crates are subjected to very high-end forces from animals running into the end of the
crates. Frequently these forces will lift the entrance end of an unsecured crate off the ground. For safe
operation, cattle crates must be securely anchored. Normally the HD series load bars are recommended for these
applications as they are designed to survive the horizontal and vertical loads generated by animals running into
the ends of the crates.
For safest operation and longest load bar life when MP load bars are used under cattle crates and crushes, it is
highly recommended that the crate or crush is restrained by chains as well as anchoring to a concrete pad.
Pinning or anchoring the load bars is preferable so that the crate remains in position after an impact load and the
chains remain slack. This will save having to lever the crate back each time the chains become taut.
The chains shown in the installation diagram prevent the crate from sliding forward or lifting at the entrance end
during weighing. The chains prevent damage to the load cell and rubber foot from excessive horizontal or
vertical loads. The horizontal chain at head height prevents the crate from tipping.
1 Fit the load bars to the crate. See Installing MP load bars on page 5.
2 Pin or anchor the load bars as required. See Pinning or anchoring on page 6.
