The TMM ( Russian ТММ, тяжёлый механизированный мост , in German: " heavy mechanized bridge ") is a military rapid bridge system from Soviet production and conceptually comparable to the nature of bridge-laying tanks. However, only off-road wheeled vehicles are used in the TMM system. The TMM system was introduced into the Soviet Army in 1964 and replaced the KMM system; it was also exported to other Warsaw Pact states . The successor is the TMM-3 system.
technology
The rapid bridge system consists of four bridge laying vehicles on the chassis of the KrAZ-214 , which is equipped with a special mechanism for unfolding and laying out a bridge segment. Four such vehicles belong to a complete bridge set. The fully deployed bridge has a length of 10.5 m, the height of the supporting pillars can be adjusted between 1.7 and 3.2 m. When a complete set of four 10.5-meter individual bridges has been completed, the result is a total bridge length of 42 meters. The completion of the assembly process takes about 60 minutes. The transfer structure is designed for caterpillar and wheeled vehicles up to 60 tons.
