In this case, the body is made of welded structural steel with strength characteristics close to armor steel.

In this case, the chassis tracks are made of asphalt.

At the same time, a warning system is installed on the tracked tractor for the safe operation of the tractor in a civil airport.

The analysis of the distinctive features showed the following

the implementation of a tractor on the basis of units and assemblies of a repair and recovery vehicle on a tank chassis with a gas turbine engine, for example, based on the BREM-80U, allows, due to the power of the gas turbine engine, to tow aircraft weighing up to 600 tons, to carry out all-weather emergency evacuation measures to release runways when emergency situations with aircraft, evacuate aircraft from any type of soil (loose, muddy), evacuate in the field during an emergency landing of a large-sized aircraft from the site of an emergency landing at an airfield;

Modification of the body of the basic BREM-80U is possible when the body is in civilian design without weapons, special communication equipment, a commander's cupola with observation devices, a filter-ventilation unit, etc. The improved design of the hull allows to increase the volume of the control compartment, which improves the living conditions for the crew, increasing ergonomic performance;

making the body made of structural steel to be welded with strength characteristics close to armored steel, allows maintaining high traction characteristics of the proposed tractor when making the body in civilian design;

execution of the tractor tracks as asphalt, allows for the evacuation (transportation) of the aircraft without damaging the asphalt pavement in the airport, while maintaining high adhesion characteristics of the caterpillar propulsion;

the installation of warning systems for the safe operation of a tracked tractor in a civil airport allows people and equipment in the vicinity to predict the actions of the tracked tractor, thereby avoiding emergency situations.

Tracked tractor for aircraft evacuation is designed for transportation and towing of aircraft of all types weighing up to 200 tons on all types of ground and over 600 on the runway in case of emergency situations.

The inventive tracked tractor (see Fig. 1-6) for the evacuation of aircraft is made on the basis of units and assemblies of a repair and recovery vehicle on a tank chassis, for example, BREM-80U, with the standard placement of the engine-transmission compartment (MTO) with a gas turbine engine 1 in aft, and contains, chassis 2, housing 3 with a control compartment 4, working equipment, including the main and auxiliary winches, opener-bulldozer 5, towing devices.

In the control compartment 4, located in the bow of the building 3, the workplaces of the crew members (operator 6 and riggers 7), organs and systems for controlling the movement of the tractor and working equipment are located. Workplaces of crew members are equipped with observation devices TNP-165, TNPO-160 8 and 9, respectively.

The working equipment is designed for aircraft evacuation and includes a main winch 10 and an auxiliary winch 11, as well as a cable delivery mechanism 12 for the main winch 10. The main winch 10 has a hydraulic drive, which creates a pulling force of up to 35 tf. To increase the tractive effort of the main winch 10, pulley blocks 13 are provided, due to which the tractive effort increases to 140 tf. The cable 14 of the main winch 10 is made with a thimble.

The towing devices of the machine include towing ropes 15 and towing rods 16. On ropes 15 defective controlled objects are towed. On the towing rods 16, faulty non-controllable objects are towed.

On the building 3 there is a cargo platform 17 for transportation of spare parts, units, lubricants and other property on a tractor.

The cargo platform 17 is made in the form of a deck of four removable anchor plates 18, used to further secure the machine on soft soils.

Towing hooks 19 and 20, respectively, are made in the bow of the vehicle and in its aft on the hull.

The body 3 of the machine can be made of any structural welded steel, while maintaining the mass of the basic machine BREM-80U. In order to improve the living conditions for crew members, the hull of the base BREM-80U can be modified by making the left and right sides of the control compartment mirror-symmetrical with an equal angle of inclination to the longitudinal axis of the hull and the aft wall of the control compartment - symmetric with respect to the right and left vertical surfaces, and in the left the side has a rectangular opening for a built-in battery compartment, hermetically isolated from the control compartment 4, while the left fencing shelf is rigidly connected to the aft wall of the control compartment 4 and the bottom of the battery compartment.

Such a modification of the hull 3 allows to increase the volume of the control compartment, thereby improving the ergonomic conditions of the workplaces of the crew members.

To prevent damage to the airport roads with asphalt concrete, as well as the runway, the caterpillar of the 21 tractor is made of asphalt.

The warning system includes flashing beacons 22, turn signals, brake lights, reverse signals and a sound signal are not indicated in the figures.

The machine operates as follows.

In the event of an emergency situation, before carrying out work on evacuation, the area is reconnoitered, the technical condition of the stuck object is determined, the need to install pulley blocks 13, the method of fixing the machine on the ground and the need to use anchor plates 18. When evacuating an aircraft located at a considerable distance from the tractor, preliminary obstacles that can interfere with pulling out and cause jamming or kinking of the cable 14 are eliminated. When unwinding the cable 14 over a considerable distance, when a great effort is required to tension and transport it to the attachment point, an auxiliary winch 11 is used. To secure the tractor on the ground, the 5 opener-bulldozer is buried.

Remove the cable 14 with a thimble from the attachment points on the machine body, extend the cable to the required distance, while issuing the cable, ensure its constant tension. If it is necessary to increase the tractive effort of the main winch 10, use the pulley blocks 13 (two, three or four branches) as shown in Fig. 6. Next, the winding of the cable 14 of the main winch 10 is switched on and thereby the aircraft 23 is pulled to the required distance.
