STUDY OF THE EFFICIENCY OF SNOW PLOUGHS IN RELATION TO SNOW CHARACTERISTICS

UNTERSUCHUNG UEBER DIE LEISTUNG VON SCHNEEPFLUEGEN IN ABHAENGIGKEIT VON DEN SCHNEE-EIGENSCHAFTEN

THE USE OF SNOW PLOUGHS RATHER THAN SNOW CLEARANCE MACHINES IN WINTERS WHEN THERE IS HEAVY SNOW OFTEN LEADS TO THE FORMATION OF WALLS AT THE EDGE OF ROADS WHICH CAUSE UNDESIRABLE SNOW DEPOSITS ON CARRIAGEWAYS AND MAY RESTRICT VISION ON BENDS. WALLS OF SNOW CAN BE AVOIDED IF THE PLOUGHS THROW OUT THE SNOW SIDEWAYS AS FAR AS POSSIBLE. THE DISTANCE THE PLOUGHS CAN THROW THE SNOW DEPENDS BASICALLY ON THE CONSTRUCTION OF THE PLOUGH, THE SPEED AT WHICH THEY CAN CLEAR THE SNOW AND THE PROPERTIES OF THE SNOW ITSELF, IN PARTICULAR ITS DENSITY. THIS STUDY IS TO EXAMINE THE RELATION BETWEEN THE CAPACITY OF THE PLOUGH (THROWING DISTANCE) AND THE DEPTH OF THE SNOW AND THE PROPERTIES OF THE SNOW, SO THAT INFORMATION CAN BE OBTAINED ON THE MAXIMUM DEPTH OF SNOW WHICH CAN BE CLEARED BY PLOUGHS AVAILABLE TODAY. MAXIMUM ROAD GRADIENTS ON WHICH SNOW CLEARANCE VEHICLES CAN BE USED EFFICIENTLY ARE ALSO TO BE ESTABLISHED.
