Mixer S942
The real breakthrough in the delivery of concrete are two models of the USSR concrete mixers S942 (the Sassi KrAZ258) and S1036 (the Sassi MAZ505B), developed and are produced VNIIstroydormashem Slavic plant construction machines with 1968 year. In general layout decisions were the same, that at the end of both models 1940s. Mixing drum was driven by a diesel engine 40 hp, useful capacity Drum at S942 was 3,2 cubic meter, while the S1036 - 2,5 cubic meter (according to the capacity of the base unit). Drum S1036 can prepare not only moving, но и жесткие бетонные смеси.
Mixer - SB92
In the early 1970s at the Research Institute has developed advanced models Stroydormash concrete mixers - SB92 on a Kraze (capacity 4 cubic meter) and SB83 on the trailer to the vehicle MAZ504 (capacity 5 cubic meters).
IN 1972 year Slavic plant construction machines began production SB92. In comparison with the S942 he had a more powerful, 50strong motor, more capacity Drum, and the inner plumage Drum had helical blades generalist, perpendicular to the conical surface Drum.
Volume of concrete mixers gradually increased in the USSR (for example, in 1973 year was released 250 machines, in 1974m - 340), but construction companies require them more and more, and Slavic plant not cope with the orders. New plant Concrete Delivery Truck was decided to build in the Bashkir ASSR in g. Tuymazy. At the same time there was built Opytnoeksperimentalny plant construction machines. In January 1980 year Order two Minstroydorkommasha plant were merged into one - Tuimazinsky plant Concrete Delivery Truck. Plant began its work quite well - only for 1980 year was released 80 concrete mixers SB92, 165 avtorastvorovozov SB89 and 15 concrete truck SB126. All this equipment was supplied not only to domestic builders, but also in Bulgaria, Hungary, India, China, Vietnam, Angola, Syria and Cuba. To 1990 year Tuimazinsky plant almost reached the design capacity: the annual output concrete mixers was 2485 units, concrete truck - 153, avtorastvorovozov - 252 единицы.
Mixer - SB92
Concrete Delivery Truck issue grew and by the beginning of the licensed production of German companies Stetter Kamenskiy experimental mechanical plant (1979 Mr.) Pushkin and mechanical-repair plant (1980 Mr.).
However, in the Soviet Union continued to develop its own model of this technique. IN 1981 year Slavic plant construction machines began production developed at the Research Institute STROYDORMASH mixer truck SB130 with drum impressive volume - 8 cubic meters, its engine running, причем на нем вместо сложной и тяжелой механической трансмиссии использовался гидравлический привод.
Mixer - SB92
The same scheme is applied to mixer trucks SB127 (chassis KrAZ6505, 1982 Mr.) and SB159 (chassis KamAZ5511, 1983 Mr.), а также на более поздних разработках.
