WEIGHING PROCEDURES
The PT300 or LP600 can be used separately, in pairs, or in groups of 4, 6, or more.
They can be used to measure a support load, wheel load, axle load, axle group load
or the total weight of a 2 or 3 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 double and triple axles 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.
COMBINATIONS FOR CORRECT WEIGHING
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.
