• A light, transportable weighbridge was demonstrated by Weighwrite Ltd., of Falcon House, Perimeter Road, Woodley Aerodrome, Reading, Berks, on Wednesday.
This flexible weighing system can be used on site for recording axle loading and gross weights of laden or unladen vehicles, producing a printed record claimed to be accurate to within one quarter in 10 tons.
The basic weighbridge kit, which consists of a load indicator, two weighing platforms and sections of track and ramp, costs £590 and is suitable for recording axle loading on smallor medium-size vehicles up to 11 tons per axle, although this specification can be altered when ordering.
From this basic kit it is possible to add sections of track, ramps and weighing platforms to measure the g.v.w. or the payload of a vehicle and to develop a system that can check weights of vehicles carrying abnormal or indivisible loads.
The load indicator, which is powered by rechargeable batteries or the ac. mainssupply, incorporates a dial with tons and hundredweight divisions, rotating switches and a recorder. The meter operates by electronically amplifying signals sent from a load cell underneath the weighing plate.
Although the weighbridge is small and light enough to be carried in a car and handled and set-up by one man, it appears sufficiently strong to withstand the wear and tear of the haulage industry. It may be used as a permanent installation sunk into a shallow concrete trough and at the demonstration the load indicator was sensitive enough to show the difference in weight when the driver left the cab of the vehicle. 0.5.
