The TMM-6 is a Russian bridge-laying vehicle. It was developed by Omsktransmash in Omsk between 1999 and the late 2000s. It was built to replace older Russian bridge-launching vehicles
Etymology
TMM-6 is an abbreviation for "Tyazhelo Mekhniznrovanny Most 6," which translates to "Heavy Mechanized Bridge 6" in English. It is also known as the "Gusenitsa-2." The original Gusenitsa-1 was the MTU-90, which was based on the Russian T-90 battle tank.
Description
The TMM-6 was designed to replace older bridge-launching vehicles, such as the Soviet T-72 AVLB. The chassis of an MZKT-7930 makes up the base of the launch vehicle. The TMM-6 has no armor, but it does feature an NBC defense system.
An earlier prototype, the TMM-5, was produced in very small quantities. The TMM-5 was based on the chassis of the Soviet MAZ-543.
Bridge
The single-span folded scissor bridge rests on a three-axle KamAZ-5350 chassis. A hydraulic winch is used to both assemble and dissemble the bridge. A single section of the bridge has a length of 17 meters, and a theoretically infinite number of sections can be added on. The sections of the bridge can be laid in gaps and water between 2 and 5 meters deep. It takes around 45 minutes to deploy the bridge. The bridge has a weight capacity of 60 tons and can, in a single hour, carry up to 400 vehicles moving at 30 kilometers per hour. A single vehicle's bridge is able to bridge a gap up to 40 meters wide.
