The vehicle is intended for laying bridges across water obstacles and dry-valley barriers of up to 100 m wide and 5 m deep for troops and wheeled and tracked vehicles weighing up to 60 tons. The bridge is used both in combat actions and during evacuation activities, elimination of the aftermath of accidents and natural disasters.

The TMM-6 comprises a bridgelayer and bridge members. The bridgelayer is a cross-country all-wheel-drive truck (wheel arrangement 8x8) which mounts equipment and mechanisms to transport and lay the bridge members. The bridgelaying mechanisms are provided with a hydraulic drive with power takeoff from the chassis engine. The bridgelayer is fitted with a system to protect the crew from radioactive dust while crossing contaminated terrain. It is also equipped with communications facilities: a radio set and an intercom system. The vehicle is environmentally safe as the bridgelaying is carried out without damming, earth moving and riverbed works.
