Russian Eastern Military District to receive TMM-3M2 heavy mechanized bridge

A TMM-3M2 heavy mechanized bridge will be delivered to Russia’s Eastern Military District (Восточный военный округ). The Eastern Military District is the second largest military district in Russia by geographic size at 7,000,000 square kilometers (2,700,000 sq mi). The Eastern Military District is headquartered in Khabarovsk, and contains 12 federal subjects of Russia: Amur Oblast, Buryatia, Chukotka Autonomous Okrug, Jewish Autonomous Oblast, Kamchatka Krai, Khabarovsk Krai, Magadan Oblast, Primorsky Krai, Sakha Republic, Sakhalin Oblast, Zabaykalsky Krai.

The vehicles is composed of four vehicles based on the three-axle Kamaz-53501 truck. Unlike the TMM-3M heavy mechanized bridge, the TMM-3M2 has a hydraulic winch for bridge assembly and disassembly instead of a motor one, which speeds up bridge section spanning, folding, lifting and lowering and reduces the time needed to erect the bridge. The full installation time is 45 minutes. The bridge capacity is 60 tons. The full set has a length of 42 m, weight 20.75 tons and is operated by a 2-strong crew.

Compared to the TMM-3M based on the KrAZ chassis, the TMM-3M2 features reduced deployment time and higher mobility. The set makes it possible to deploy bridges with a width of 40 meters for wheeled and tracked military hardware. The mechanical outriggers were replaced with hydraulic ones to reduce the time for unloading the rear axle suspension and for eliminating a roll of the bridge launcher and to reduce the number of manual operations. A rear camera has been installed to allow observation of the installation of the support brackets of the bridge bays.
