Porsche type 335 is a belt driven winch intended for agricultural use in post-war Austria.
History
edit
At the end of World War II the Porsche company Porsche Konstruktionen Ges. m.b.H was located in Gmünd, Carinthia in Austria. The company survived by repairing passenger cars, trucks and agricultural machinery. Next to this they took on commissions for various machinery used in the local area such as wind turbines, engines for ski lifts and winches.[1] The type 335 winch design was particularly useful as surface winch for farmers in mountainous areas.[2] A handcart was designed for the winch under Porsche type number 337.
