SCAMMELL ROADTRAIN SETS THE PACE IN THE TEST YOU CAN TRUST

The Road Hauliers Association new computer track test is described. The test gets rid of the number of variables such as driver, weather, road conditions, traffic flows and other environmental factors affecting road tests. Four types of road are built into the model- suburban, central urban, main "a" category roads and motorways. The actual rate was calculated using advance survey maps and was utilised to supplement the computer simulation with subjective road impressions. The test vehicle was fitted with new Cammins Super E series 320 bhp power unit. Aerodynamic characteristics and an engine fuel map were supplied by the manufacturers. Driver behaviour was simulated by using five gears when unladen and eight when fully laden. Other parameters regarding wheel diameter, unladen weight of the tractor/trailer combination and the power absorbed by accessories were defined. Loadings of 50 per cent as well as fully laden and unladen were simulated for a box body and flat trailer. Results showed that the scammell compared favourably with other vehicles tested subjectively and by the simulation.
