High Quality Content by WIKIPEDIA articles! Saipa Diesel Company, originally branded Iran Kaveh, is an Iranian-based manufacturer of trucks and trailers. The company began operations in 1963 under an exclusive agreement with Mack Trucks to assemble their trucks and various types of trailers. By 1978, the factory was producing a total of 7,512 units. During the years 1979-1984, the company began assembling a wider variety of vehicles in both the cargo and passenger sectors, in order to prevent the shutdown of the factory and make use of existing capacities. In 1984, having carried out studies on restarting the truck production line, a contract was concluded for the production of Volvo F4x2, 6x2, and 6x4 trucks. In the same year, another agreement was sealed with Coscha, a former Yugoslavian company, to produce platform semi-trailers.
