The pioneering machine MDK ( Russian Машина дорожная котлованная МДК - in German: Road grave machine ) referred to as MDK-2M Erdfräse, is in the Soviet Union developed off-road, unarmored, not floatable caterpillar , which pioneered machine or Erdfräse on the chassis of the AT-T was built. AT-T stands for Russian артиллерийский тягач - тяжёлый (artillery traction means - heavy).
use
The MDK-2M were used for the rapid excavation of large covers and for pulling armored trenches (excavation depth up to 4.7 meters and trench width 3.5-4 meters). The milling cutter, which is mounted on the rear of the vehicle for displacements, is hydraulically lowered to the rear for the milling process.
construction
The chassis and the propulsion system were taken over from the T-54 battle tank , but the hull was rotated. The engine, clutch, gearbox, steering gear and drive wheels are now in the front of the vehicle, the guide wheels of the drive in the rear. The cabin for the crew is also located in the front part of the vehicle. The cab of the ZIS-150 or ZIL-164 truck was used for the construction . The original cab was widened. It now offered space for four crew members. The cooling system, air filter and ancillary units are located under the original bonnet, the 12-cylinder diesel engine W-401 (a reduced-power variant of the W-2 ) is located below in the tub. The roller drive consists of five rubber-tyred twin rollers. The suspension takes place via torsion bars.
With the 500 millimeter wide crawler tracks, a maximum ground pressure of 0.652 kg / cm 2 is achieved. The gradeability is a maximum of 40 °, the ground clearance 425 millimeters. The vehicle can cross trenches up to 1.8 meters wide and, without preparation, drive through bodies of water up to 1.1 meters deep.
Users
The MDK-2M were used by the Soviet and Russian armed forces, the Hungarian People's Army and the East German NVA. A Hungarian copy is on display in the Swiss Military Museum Full .
