The pioneering machine MDK-3 ( Russian Машина дорожная котлованная МДК-3 - in German: Road grave machine MDK-3 ), also known as MDK-3-Erdfräse, is in the Soviet Union developed off-road, unarmored, not floatable caterpillar , that or a pioneer machine was developed as an earth milling machine on the chassis of the MT-T in the 1980s. Internally, the vehicle was also referred to as product 453 (изделие 453). MDK-3 is the successor to the pioneering machine MDK-2M . The MDK-3 is in service with the Russian and Ukrainian armed forces .

technology

Like its predecessor, the MDK-2M, the MDK-3 was designed for the rapid excavation of large coverings and for pulling anti-tank trenches. The earth milling machine mounted on the rear of the vehicle is hydraulically lowered to the rear for the milling process. The 12-cylinder diesel engine W-46-4, a power-reduced variant of the diesel engine W-2 with 710 hp and 38.88 liters displacement, is located directly behind the driver's cab, which can accommodate a maximum of five people. To protect the crew, it has an NBC protection and ventilation system, which is intended to ensure persistence in areas contaminated with NBC weapons. The chassis consists of seven pairs of rollers, the suspension is provided by torsion bars. The earthworks of the MDK-3 are carried out in reverse. Depending on the nature of the ground , the milling capacity is 50 to 100 meters per hour on average. An excavation depth of 1.75 meters can be achieved per pass, the maximum depth is 3.5 meters, so that loose material can be safely ejected. The trench width is 3.5 meters. With optimal soil conditions, a depth of around two meters with a pit width of 3.50 meters can be achieved in one operation. The work performance amounts to almost 200 meters per hour. A maximum of 800 m³ of material should therefore be excavated per hour. The vehicle is also equipped with a clearing blade that can be used to fill in trenches and depressions, but can also be used to remove frozen topsoil up to 75 cm.
