Installation overview

Caution: Under no circumstances should the load bars be welded to anything, or be attached to any equipment
being welded.
Installing load bars
The load bars are mounted beneath the platform.
The installation must be tested before first use and should be checked periodically thereafter.
The platform, crate, crush or squeeze chute must have mounting holes to match the load bars.
The 'hoof' width (width on which the animal can stand) of the platform, crate, crush or squeeze chute must be
no wider than the length of the load bars.
The load bars should be mounted as near to the ends of the platform, crate, crush or squeeze chute as practical -
within 200 mm (8").
For the 1010 mm (39") load bars it is important that the platform, crate, crush or squeeze chute load is applied
to the load bar through two points at a minimum of 600 mm (24") apart, and that the platform, crate, crush or
squeeze chute is placed centrally on the load bars.
To prevent your weighing system from sliding, load bars can be pegged or pinned by fitting mounting studs into
the foundation.
Preventing platform movement
There are three methods of restraining the platform:
Beams secured to the concrete pad to contain the load bar assembly thereby preventing movement.
•
Pinning or anchoring the load bars of the load bar assembly to the concrete pad.
•
Chaining to secure features such as posts to prevent movement. The chains must be slack to ensure correct
•
measurements.

Cable routing

Cables should be placed so that they will not be walked on, chewed by animals or squashed in any way. Placing
the cables inside heavy plastic hose, under timber, underground, or attached to posts will help prevent damage.
Cattle crates
Normally the HD series load bars are recommended for these applications as they are specifically designed to
survive the horizontal and vertical loads generated by animals running into the ends of the crates. To prevent
excessive side loads on the load bars, Tru-Test recommends the use of restraining chains to control these loads.
Caution:
- Do NOT weld any installation attached to the load bars. The load bars contain calibrated electronic circuitry
that is easily damaged by stray currents and voltages induced by welding.
- The total weight of the platform or crate must rest upon the load bars. If the load bars are not supporting the
full weight then inaccurate and inconsistent readings will result. Ensure that the load bars and platform or
crate are clear of any obstruction, and that the installation is level.
- If the load bars are permanently installed, choose a location for the load bars that drains well and can be
easily cleaned. Although the load bars are coated to prevent corrosion, prolonged exposure to moisture or
manure will reduce the life of the load bars.
