Dirt truck 2T3 (2T3M, 2T3M1) is a semi-trailer of special design, working in a clutch with a specially equipped tractor ZIL-157KV (for 2T3, 2T3M) or ZIL-131V (for 2T3M1).
The trolley is designed:
- for the carriage of one loaded or unguided 8K14 or 8K11 (8A61) missile with or without a warhead, as well as two unguided 8K14 or 8K11 (8A61) missiles without warheads placed on a 2Sh3 (or 8T04) container, on unpaved and highway roads at any time of year and under any weather conditions within the temperature range of -40 to +50°C and wind speed up to 20 m/s;
- to perform working operations on them with 8K14 and 8K11 missiles at the missile preparation point, at the installation and refueling point and at the point of missile loading to the launching unit;
- to store the missiles and carry out regulatory work.
When transporting on the cart 2T3M (2T3M1) of one filled missile 8K14 or 8K11 docked to a special head end (HC), and on the cart 2T3 of one filled missile 8K14 docked to a special HC provides for electric heating of HC with the necessary thermal mode. The trolleys carry a thermal cover 2Sh2, designed to maintain the temperature regime and protection of MS missile 8K14 or 8K11 from meteorological effects and solar radiation.
The trolley has three beds: front, rear and additional. The front bed is welded into the frame of the semitrailer. Rear and additional beds are removable and are installed on the balancer of the semitrailer. The balancer can be rigidly fixed on the frame of the semitrailer, which is required for all cases of transporting 8K11 missile, as well as 8K14 missile without HF. To transport 8K14 missiles with a fixed GN, the rear and additional beds must be free of attachment to the semitrailer frame. The missile is placed on the rubber pads of the front and rear box bandages and is attached to the front box by stretch marks (with the help of fittings), and to the rear and additional - by bandage awnings. The sectors of the front and rear box bandages are rotatable, which allows you to rotate the missile laid on them around the longitudinal axis in both directions. To drain the fuel components and neutralize the oxidizer tank of the missile, the trolley attaches removable sectors to the sectors of the front and rear spoon bands, which allows you to rotate the missile 360° around its longitudinal axis.
Trolley 2T3M (2T3M1) is equipped with an electric system for internal heating of the HC of 8K14 and 8K11 missiles, trolley 2T3 is equipped with an electric system for heating the HC of 8K14 missiles and for heating the HC of 8K11 missiles is not adapted. Electrical equipment for trolley 2T3 heating: benzoelectric unit AB-2-0/230 with rated voltage AC 230V and transformer OS-2/0,5-230/40. For trolleys 2T3M and 2T3M1 - generator GD-74 with nominal voltage of a direct current of 28В. In the complete set of the electric equipment of heating of MS of a rocket there is a panel POG-3 (for 2T3) or POG-5/POG-5M (for 2T3m, 2T3M1) intended for inclusion of heating, the control, measurement, regulation and the alarm of temperature MS in two volumes: the bottom "NO" and the top "ВО".
On both sides of the frame of the semitrailer the right and left refueling tanks are fixed with clamps, intended for transportation of two doses of starting fuel TG-02, issued to the refueling tanks of the starting unit. The trolley carries two ladders and two folding platforms, which are used to service the missile on the trolley. The platform is universal and can be used as a support for the installation of gyro devices during the testing of the rocket at the checkpoint of the rocket. It is also possible to transport exchangeable cables and hoses for one missile.
Tractor equipped with 2T3 trolleys - ZIL-157KV truck tractor with increased cross-country ability with three driving axles, winch, double-jointed fifth wheel coupling, equipped with a heating system for heating the GC on alternating current (only for missiles 8K14 (8K14-1)).
Tractor equipped with 2T3M trolleys - ZIL-157KV truck tractor with increased cross-country ability with three driving axles, winch, double-jointed fifth wheel coupling, equipped with a heating system for HF on direct current (for missiles 8K14 (8K14-1) and 8K11).
Tractor equipped with bogies 2T3M1 - tractor ZIL-131V of increased cross-country ability with three driving axles, a winch, a double-jointed semitrailer coupling device, equipped with a heating system of the head part on a direct current.
The maximum admissible speed of movement with a rocket on highway with the improved covering in good condition - 40км/hour, on the improved soil, cobblestone, rubble and gravel roads - 20км/hour.The brake system of a semitrailer - the pneumatic, operating from air system of the tractor and mechanical with a manual drive of brakes on parking, brakes of a semitrailer - kolodok from car MAZ-200.
Number of railway gondola cars required for transportation of bogie - two four-axle gondola cars with carrying capacity of 60 t or two-axle gondola cars with carrying capacity of 20 t or one two-axle and one four-axle gondola car Number of railway gondola cars required for transportation of container 2Sh3 with three missiles without head units - one four-axle gondola car with carrying capacity of 60 t (it is allowed to transport missiles in wagons 8T45 and 8T46 in containers 2Sh3 and 8T04). Container 2Sh3 is also used to transport three missiles in an open railway gondola car. The 8T04 container for the transportation of missiles in a gondola car is not adapted, as it has no stretch marks for fastening.
It can be transported on bogies:
- one 8K14 missile with a hC, mounted on the front, rear and auxiliary boxes, or without a hC, mounted on the front and rear boxes and covered by a tent;
- one 8K11 (8A61) missile, mounted on the front and rear decks and covered by awning;
- 2Sh3 (8T04) container covered by a tarpaulin, with two 8K14 or 8K11 (8A61) missiles without HF mounted on it;
- 2Sh3 (8T04) container without missiles.
The 2T3 trolley device (2T3M, 2T3M1) ensures the following work operations on it:
- loading an empty container 2Sh3 (8T04) onto a cart and unloading it;
- loading a container cart with two missiles and unloading a container with missiles;
- loading, securing to a cart and transporting an unguarded, unladen, as well as a fully loaded, docked MS missile;
- conducting horizontal testing of the missile at the missile preparation station;
- fuelling the missile with the main fuel components;
- docking the MS to a cartloaded missile;
- putting on the 2Sh2 thermal cover on the MS;
- switching on the electric internal heating system and heating of a special 8K14 (8K14-1) or 8K11 missile (2T3M and 2T3M1 trolleys) and heating of 8K14 missile (2T3 trolley);
- refueling the right and left tanks of the trolley with starting fuel TG-02;
- Laying, fixing and transportation on the trolley set of replacement cables and hoses for the missile;
- covering of the rocket with a tent;
- loading of the rocket with the help of a regular crane and cross beam from the trolley to the launch unit and the issuance of starting fuel TG-02 from the tanks of the trolley into the tanks of the launch unit.
In the event of a failed rocket launch and the need to disconnect the MS and drain the fuel components on the cart, the following work operations may be performed:
- disconnecting the HF from the missile;
- draining the oxidizer and the rocket tank;
- draining the main fuel and the rocket tank;
- neutralizing the missile's oxidizer tank.
