• To be shown at Earls Court is an axle load-sensing device, providing dial readings in the cab, that has been fully tested over a period of three to four months fitted to a Bedford 7-ton tipper. It will be marketed by JAR Developments (Garage Equipment) Ltd., 26-27 Bissell Street, Birmingham 5, and its estimated cost is £100120 installed.
Each side of the front and rear axles of the vehicle is fitted with a "black-box" unit between the axle and the chassis comprising a variable-pulse generator connected to a meter in the cab. Because the electrical parts of the control unit do not make physical contact, wear and tear is negligible and full weatherproofing is provided by cocooning the unit in resin. Current is supplied by the battery.
The fitting of two units to each axle enables load distribution to be accurately evaluated.
