The Granit 30k / Robur Garant 30k phenomenon is a type of truck from VEB Robur-Werke Zittau . The type Granit 32 or Garant 32 was a derived version with a diesel engine. The two-tonne truck was located in the former GDR vehicle construction above the Barkas V 901/2 and below the IFA H3A .

history

In 1953, the production of the Granit 30K began as the successor to the Granit 27 phenomenon . It had an improved gasoline engine with 40 kW output, which essentially consisted of the components of the Granit 27 and Granit 32 engine. The new addition "k" stood for "head-controlled", the 30 for 30 dl displacement. In addition, the diesel variant Granit 32 , which had been announced for some time, has now been produced. Externally, the Granit 30K was initially hardly distinguishable from its predecessor. This changed in 1955 when the vehicle was given a new design, in line with the taste of the time. It was also equipped with a flashing system. The engine output was increased to 44 kW in 1957. One shortcoming of the vehicles was the difficult accessibility of the spark plugs, which could only be reached after the air duct box had been removed. In 1958 the steering was improved and the fan belt could from then on be tensioned by means of the alternator. The vehicle was manufactured with a wide variety of bodies, for example a sales car was presented in 1958. Some of the vehicles were equipped with all-wheel drive . In April 1961, the 50,000 unit of this model series rolled off the assembly line.

Due to a successful lawsuit by Rudolf Hiller, who, after the expropriation of his Phenomenon factories, had worked with some of his engineers at the Hanomag factory as technical director, the company in Zittau was renamed VEB Robur-Werke Zittau on January 1, 1957 and the Vehicle models were named Garant on July 1, 1956 .

export

Granit 30k and 32 were presented at numerous international trade fairs and exported to more than 20 countries in 1954 alone; in 1959 there were already almost 40 countries. Important customers were the ČSR , Hungary , Belgium and the Federal Republic of Germany . The undemanding air cooling gave it an advantage over its competitors in tropical and dry regions of the world. No cooling problems arose even under heavy loads in extreme heat in Africa. Especially as an all-wheel drive version, the Garant 30 K made use of the great torsional stiffness of the frame and its great climbing ability. For example, the vehicles were used as ambulances on impassable mountain roads in Bulgaria and proved to be surprisingly robust. Of the 6250 vehicles manufactured in 1957, 3000 were exported.

Special variations

The special Kfz-1 was based on the Granit 30K and was the only armored vehicle mass-produced in the GDR. It was produced in 1953/54 and initially put into service by the barracked people's police . The vehicle was later used by the combat groups .

Granit 32 / Garant 32

The Granit 32 or Robur Garant 32 phenomenon was a diesel version of the 27 or 30k model. The diesel was announced and described as Granit 32 as early as 1951. Production was already running in September 1952. However, an all-wheel drive version of the Garant 32 A could not prevail among the armed organs . In 1956 the vehicle was renamed from Granit 32 to Garant 32 .

Granit 30k A / Garant 30k A and Garant 30k AW / Zg

The 4 × 4 Granit 27 A was built in 1950/51 to meet the need for all-terrain traction devices . From 1953 to 1955 this was listed as Granit 30k A. The further development based on the Robur Granit 30k A was produced from 1955 as a Garant 30 k AW / Zg with a new design. The vehicle was mainly used by the armed organs with a simple crew cot, as a news van, as a staff box wagon or as a traction device (AW / Zg). The vehicle had a payload of 1000 kg. The top speed was 80 km / h. The version of the Garant 30k AW / Zg had a smaller wheelbase (2900 mm) and other external dimensions (L / W / H: 5310 mm / 2100 mm / 2610 mm).

Ambulance RTW

The ambulance RTW on the chassis of the Robur Garant 30k was manufactured between 1957 and 1960. The structure was created in VEB Karosseriewerke Halle . The vehicle had a crew of 1 + 3 people, which could be increased to 1 + 8 if necessary. There was also a fold-up bench in the ambulance. The equipment included four stretchers, an armchair and a folding seat . This enabled four recumbent and two seated or two recumbent and five seated people to be transported in the ambulance. The vehicle had a 4 × 2 rear-wheel drive with a sedan-like structure. In the all-wheel drive variant (Garant 30k A) the box body was separated from the driver's cab. The top speed was 80 km / h. The vehicle had special shock absorption and suspension. The Robur ambulances were replaced by Barkas B 1000 ambulances from 1960 . The Robur company later developed the mobile ambulance (LD-AFr6 / Mz-A) .

The bus was produced as a successor to the Robur Garant 27 VW / B 18 from 1956. The type designation VW / B18 means extended wheelbase, chassis with cowl, bus, 18 seats. Due to its robustness, the bus was used by the NVA, among others . It was ideally suited for transporting small groups and should be used as a transport for the wounded in the event of war.

Fire truck LF-TS 8

The fire fighting group vehicle LF-TS 8 was built from 1953 on the basis of the Granit 30k A phenomenon. The superstructures were manufactured in the VEB fire extinguishing equipment factory in Görlitz . The vehicle had a crew of 1 + 8 . The vehicle was equipped with two oxygen protection devices, 8/8 portable pumps and 180 m C pressure hoses and 240 m B pressure hoses.

Fire truck LF-LKW-TS 8-STA

The increasing demand for inexpensive fire fighting vehicles (LF) led to the introduction of fire fighting vehicles with portable fire pumps (TS) and hose transport trailers (STA) in 1956. The 4 × 4 all-wheel drive vehicle had a 1 + 8 crew. In addition to the TS 8/8 portable pump, the vehicle had 135 m of C pressure hoses, 545 m of B pressure hoses and two oxygen protection devices on board. The basic structure of the vehicle was a flatbed vehicle with a bow and tarpaulin. The hose transport trailer carried a further 420 meters of B pressure hoses with it.
