DEVELOPMENT OF A SNOW PLOUGH/SALT SPREADING VEHICLE FOR ICE AND SNOW CLEARANCE OF MOTORWAYS IN ENGLAND

In 1973 it was decided that the Department of the Environment would confine itself to supply vehicles for highway winter maintenance only. This prompted a different design approach because the operational parameters of a snow-plow/salt spreading vehicle for use only on highways dictates different design requirements. The general requirements of the chasis/cab called for a gross vehicle weight of 24 tons, a 6x4 configuration, a tractive effort of 25,000 lbs. with a low center of gravity. Some of the body design specifications were: a payload capacity of 12 tons with a spreading device at the rear of the body, a hopper shaped body to give good salt flow, a cable of spreading salt to a width of 60 feet symmetrically and asymmetrically, and a spread rate from 1.16 oz./sq. yd. (40 g/sq. m) down to .29 oz./sq. yard (10 g/sq. m). From operational trials that spanned three winters, it was concluded that the greatest benefit of such a vehicle is the capability to spread salt at .29 oz./sq. yard (10 g/sq. m) for the precautionary salting operation, which is unattainable with the existing 6x6 vehicles. The major areas of cost benefit of these vehicles are: savings of about 30% on salt usage, savings of 40% on cost of 6x4 chasis/cab as opposed to 6x6 reduced service and maintenance costs of 20%, and increased operational efficiency due to savings in staff time and vehicle down time.
