V3S = Vojenský Třínápravový Speciál

We are convinced that the Praga V3S is not only a genius truck of its simplicity to these days. Great are not only its technical parameters, but also the history of how V3S was created.

Its production began soon after World War II for the assignment of the then Czechoslovak army. The fleet was composed of several hundred types of spoil vehicles. Vehicles were often unreliable and in poor technical condition, fleet diversity was very complicated in service and maintenance.

The development was started in the National Enterprise in Prague in 1951 and the first prototype was finished for half a year. The construction was commissioned by the General Staff on August 28, 1951. The main requirements were, for example, a maximum weight of 5,500 kg, a weight of 3000 kg, a minimum size of 550 mm, a diesel air cooled engine, or a requirement for conformity with the technical design of the Russian vehicle ZIS 151. However, the developed vehicle project was far superior. The construction of the first functional prototype was completed on February 20, 1952.

ZIS 151 (source wikipedia.org)

The basic concept of Praga V3S is a frame with three rigid axles. Each axle has wheel reductions to increase terrain penetration and is driven from the gearbox by its own drive shaft. The engine is diesel, air-cooled with direct fuel injection.
