Models of excavated MDK machines

When in 1946 there was a need for the production of tanks, and the plant was urgently redesigned to produce new products, at the same time, several designers who worked at the A. A. Morozov Design Bureau (Kharkov), headed by M. N. Shchukin and A. I. Avtonomov, began to develop a tractor (index 401), the basis for which was the T-54 tank. The customer of the work was GAU and CAVTU. After successful testing of this machine, the serial production of the artillery heavy tractor (AT-T) began in 1953.

The purpose of the MDK-2 or MDK-2m excavation machine, which is based on the AT-T heavy artillery tractor (it was produced in 1950-1979 at the Malyshev Kharkov Machine-Building Plant), is to tear off ditches measuring 3.5 by 3.5 meters. They can have any length. The technique can be used in the presence of a wide variety of soils (including the fourth category). Thanks to the installed bulldozing equipment, it is also possible to plan the terrain before tearing off the excavation, cleaning and leveling the bottom, filling pits, trenches and pits.

The machine lays the excavated soil on the right side of the trench ten meters away from it. In the process of a single passage, the excavation deepens by 30-40 centimeters. The working body is a milling cutter on which the thrower is mounted. The machine operates with a capacity of 300 cubic meters per hour and has a transport speed of 35.5 kilometers per hour.

The first prototype of the excavation machine was the MDK-3 model. Its purpose is to tear off excavation pits with a width of 3.5 meters and a depth of 5 meters, where military equipment can fit. The working body was placed on a tractor (AT-T), on which an additional power plant was mounted, thus, the power of the power units increased to 1115 horsepower! In the presence of soils of the first or third category, the machine operates with a capacity of 1000 to 1200 cubic meters per hour. The equipment weighs 34 tons.

Later, the MDK-2m excavation machine was upgraded to the MDK-3 version. This technique was used to dig trenches and shelters for military vehicles. She also successfully tore off excavation pits for the manufacture of fortifications. The basic framework was represented by a multi-purpose heavy tractor MT-T tracked type. It was developed by the Kharkiv Morozov Design Bureau.

The production of this equipment was established at the production facilities of the Malyshev Kharkov Machine-Building Plant (in 1976-1991).

The machine lays the spent soils on the left side of the recess, in the form of a parapet. During the operation of the MDK-3 excavation machine, a reverse gear is used, and during a single passage, the excavation is torn off, the depth of which reaches 1.75 meters. Additional equipment is represented by a powerful bulldozer installation and a ripper (for tearing off frozen soil), which made the machine more functional (when compared with its predecessor"). The machine operates with a capacity of 500 to 600 cubic meters per hour. Transport speed indicators reach 65 kilometers per hour.
