The invention relates to crossing-bridge means and can be used to provide terminal equipment through water obstacles, as well as for transportation of various cargoes by water and by land.

The main requirements for this kind of equipment, representing a floating machine with propulsion and steering complex, are: the provision of the necessary capacity, buoyancy and stability, good propulsion and manoeuvring qualities of both afloat and on land.

Known floating conveyor average PTS/PTS-M adopted for service with the Soviet Army in the 1960-ies (see "JNTERCONAIR ARMIES and WEAPONS", January, 1979, page 28). The conveyor is made on the base chassis of tank T-55 and its construction used engine, transmission, main element is water obstacles up to 50 soldiers in combat uniforms. The disadvantages of the known conveyor due to the low capacity and small size of the cargo platform.

Known floating crawler Transporter PTS-2, which is the closest analogue, i.e., the prototype of the proposed object (see "Technical description and operating instructions". M: Voenizdat, 1979), made on the chassis of the crawler Transporter MT-T, which in turn made using the master nodes battle tanks T-64 and T-72. The conveyor consists of a waterproof housing with a front location engine compartment, the engine used on the T-72, transmission, made in the form of guitars, gear box changes gear (transmission) and two planetary gear mechanisms turn (RAP), chassis with 7 pairs of metal road wheels and the propulsion and steering of the complex formed by two jet engines mounted in the rear of the chassis. In comparison with TCP-M, Transporter PTS-2 has slightly more cargo platform and a higher lateral walls (Board) that provides more displacement and load capacity. The rear of the machine has an unloading ramp, which is installed on the ground using Gidropress of transmission units in the form of a box changes gears and two planetary gear mechanisms of rotation, used in military tracked vehicles of the first generation, it is not possible to meet the modern demands on dynamics and maneuverability at movement on land and utilize the full capabilities of the engine of the T-72;
