An improved version of the Weighwrite ADS Dynamic Axle Weighing System is now available from Smiths Industries. The weighing beam, which can be transported between pre-prepared sites on a purpose-built trailer, is unaltered. But the electronic head now produces' a digital axle-weight readout and a further printed read-out quoting individual axle loads.
Time and date and gross vehicle weight readings — the sum of the axle weights — are available on the printout as an optional extra.
The equipment reads the weights of axles passing over the weighing beam at speeds of up to 3.5 km/h (2.2mph) to an accuracy of + 1 cwt, or 0.31 per cent per axle. And although it can be used to weigh static loads to the same limits, the dynamic method is considered by Weighwrite to be more accurate for determining the individual axle loads on balance beam suspension units.
Price: between £2,750 and £3,060.
