Polar Transportation Equipment -Five-Ton Truck with high Flotation Tires.

摘要

A 5-ton truck with 19.75 x 20,low-pressure,high flotation tires was tested in the continental United States and at McMurdo,Antarctica to determine its suitability as a cargo transporting vehicle in snow-covered polar regions. The tests indicated the vehicle was satisfactory when operated on well-constructed,hard-packed snow roads,but unsatisfactory for operation over deep,undisturbed,snow surfaces as well as over partially compacted surfaces such as snow trails processed by vehicle traffic.
