The IFA H3A was a light truck , which was built from 1951 to 1958 in the VEB Horch motor vehicle and engine works Zwickau . The three and a half tonner was located in the former GDR vehicle construction above the phenomenon of granite 27 and below the IFA H6 .
In March 1948 began in Zwickau with the development of the H3A. Series production started in 1950, but the first vehicles still bore the Horch emblem. The H3A was the first truck developed in the GDR . The main distinguishing feature to the predecessor H3 was the typical Langhauberkabine , which found itself in similar form at the larger H6. In 1957, the H3S presented a further development with a modified transmission and thus an increased top speed of 74 km / h, of which, however, only a few units were built. 1958 began the production of the visually similar successor model IFA S4000whose 4-tonne payload and 30-centimeter longer wheelbase are among the biggest changes. The H3A produced more than 30,000 vehicles by 1958. The main exporting countries were the People's Republic of China and Bulgaria .
IFA H3A Truck Chassis
The H3A had two axles and was rear wheel driven via a cardan shaft. The weak point was the crankshaft with only three bearings and four bolted counterweights. From 1956, a five-fold crankshaft was used. The IFA unit pump served as an injection pump. The truck was a so-called Langhauber with "muzzle". For export, the H3S was built in parallel from 1956. These special versions featured H6 / G5 transmissions, air brakes and longer wheelbase.

Application and use
The truck was mainly intended for civilian use. However, it was also used by the People's Police and the kasernierten Volkspolizei , later by the NVA . Through its many variants, including flatbed trucks, three-way tipper, furniture trolley, road tractor or semi-trailer, the H3A was in the former GDR an undisputed progress in technology. For example, the H3A tanker was manufactured as a solo machine and as a tractor-trailer vehicle. Special bodies for patient transport were manufactured for the Red Cross , as well as for the post office as panel van and for the fire brigadeswith several bodybuildersExtinguisher vehicle , tanker , hose trolley and equipment trolley .
In the late autumn of 1956, a test drive through Tibet with converted to anthracite gas H3S vehicles was carried out to test the suitability for export to China. It was found that the vehicles are not suitable for the temperatures of less than -20 ° C occurring there. A diesel H3S had to be started regularly at night to prevent it from overcooling. Apart from that, however, the vehicles proved themselves well and proved their robustness. A little later counted China the largest purchaser of the vehicles.
Based on the H3A 1952, the tractor Z3 with a short wheelbase of 2500 millimeters. The vehicle was built until 1958 in only a small number of pieces. However, with the 80 hp Horch engine EM 4-20 the vehicle was underpowered.
The H3B front-mounted handlebar (for Horch, 3 t payload, bus ) was based on components of the H3A, which were installed on a low-frame chassis for buses. In the period from 1952 to 1958, in addition to a few hundred buses and coaches, a number of lorry vans were built, which were often used as furniture transporters.
