IN response to an £18,000 order placed by the Ministry of Technology, six prototype hydrostatically driven dump trucks are being built by a Lincolnshire company and are to be tested by the National Engineering Laboratory. of East Kilbride.
It is anticipated the vehicles will be ready for use by March, when they will be handedover to a number of civil-engineering contractors for testing on arduous building-site work. Three will have two-wheel drive and the others four-wheel drive.
A senior NEL scientist says that the motor industry has shown increased interest in hydrostatic drive over the past year. The dumpers represent the latest stage of more than 10 years of NEL research into hydrostatic systems and may well be the forerunner of applications to lighter vehicles.
It is pointed out that hydrostatic transmission can eliminate the need for service brakes and gearbox and clutch. Braking, gear ratio variation and disengagement can be controlled by a single pedal that regulates oil pressure.
