• Two transportable commercial vehicle weighing systems, designed first used in Sweden, are now being marketed in the UK by Oxy Finishing (Great Britain) Ltd, Sheerwater, Woking, Surrey.
Designated the "10T" and "40T", both systems use portable weig plates which are laid on the ground in front of the vehicle wheels — vehicle is then driven on to them.
The 101' system uses two, four or six plates, each having its own d read-out meter. The observer notes the reading from each plate and them to get axle and/or gross vehicle weights.
The 40T system uses only four plates, each connected via a cable remote reading head. Instead of indiv wheel readings, one total reading for the plates is given at the head. The unit , total weight: thus, to measure axle load on two plates only, the remaining r must be unladen.
A similar 60T system using six pla being developed.
Tests by the company with a 10T s) and a fully laden 24-ton, three-axle showed a gross vehicle weight error of cent when compared to readings frc conventional weighbridge.
Weighing about 501b each, the g read up to 10 tons and measure 24ii 18in. by 3.5in. Individual plates for the system cost £1200; the complete system costs £3750.
