Weighing procedures
The PT300 platforms can be used separately, in pairs, or in groups of 4, 6, or more to measure
a support load, wheel load, axle load, axle group load, or the total weight of a multi-axle truck
in one measuring procedure.
Ideally, all wheels of a vehicle should be measured at the same time in order to avoid
measuring errors due to the suspension system.
If you are not able to weigh the wheels of a tandem or triple axle simultaneously, the difference
in height must be compensated for by using dummy plates (grids, wood or rubber plates) of the
same height. The wheel load scales are put in front of the wheels of a vehicle, the driver then
drives on the scales/plates and stops within the active weighing area. To avoid improper
weighing which might be caused by wheel or axle load displacements, the vehicle brakes
should be released before reading the weight values.
NOTES:
1. It is recommended to weigh the wheels of one axle at the same time.
2. The dummy plates can be omitted if the scales are embedded in recesses in the road surface
at the same levels as the road surface.
