The armored vehicles of Russia and the world, photos, videos, watch online, were significantly different from all their predecessors. To provide a large reserve of buoyancy, the height of the hull was noticeably increased, and to improve stability, its cross section was given a trapezoidal shape. The required bullet resistance to the hull was provided by rolled cemented armor with an additionally hardened outer layer of the KO brand (Kulebaki-OGPU). In the manufacture of the hull, armor plates were welded on the inner soft side, and special stocks were used to facilitate assembly. To simplify the installation of units, the upper armor plates of the hull were made removable with a seal on fabric gaskets lubricated with red lead.
Armored vehicles of the Second World War in which the crew of two people was located near the longitudinal axis at the back of each other's heads, but the turret with weapons was shifted 250 mm to the left side. The power unit is shifted to the starboard side in such a way that access for engine repairs was possible from inside the tank's fighting compartment after removing the safety partition. At the rear of the tank, along the sides, there were two gas tanks with a capacity of 100 liters each, and directly behind the engine there was a radiator and a heat exchanger, washed by sea water when moving afloat. At the stern, in a special niche, there was a propeller with navigable rudders. The balance of the tank was chosen in such a way that when afloat it had a slight trim to the stern. The propeller was driven cardan shaft from the power take-off mounted on the gearbox housing.
Armored vehicles of the USSR in January 1938, at the request of the head of the ABTU D. Pavlov, the tank’s armament was to be strengthened by installing a 45-mm semi-automatic gun or a 37-mm automatic gun, and in the case of installing a semi-automatic gun, the crew was to be increased to three people. The tank's ammunition was supposed to consist of 61 rounds for the 45 mm cannon and 1,300 rounds for the machine gun. The design bureau of plant No. 185 completed two projects on the “Castle” theme, the prototype of which was the Swedish Landsverk-30 tank.
The Wehrmacht armored vehicles did not escape troubles with engine boost. To what has been said, we can only add that this crisis was actually overcome only in 1938, for which the tank received not only a forced engine. To strengthen the suspension, thicker leaf springs were used. Rubber tires made of neoprene, a domestic synthetic rubber, were introduced, the production of tracks from Hartfield steel by hot stamping began, and high-frequency-hardened fingers were introduced. But all these changes to the tank were not introduced simultaneously. The tank hull with inclined armor plates could not be manufactured on time. However, the conical turret with improved protection was submitted on time, and the tank with the same hull, reinforced suspension (due to the installation of thicker leaf springs), a forced engine and a new turret entered testing at the NIBT test site.
Modern armored vehicles went under the code T-51. It retained the process of transition from tracks to wheels, like the prototype, by lowering special levers with wheels without a person leaving. However, after adjusting the requirements for the tank, making it a three-seater (it was decided to retain backup control for the loader), and strengthening its armament to the BT level, it was no longer possible to implement the Landsverk-type wheel drive. In addition, the tank's wheel drive transmission was overly complex. Therefore, soon work on the “Castle” theme was carried out on the T-116 tank, in which the “change of shoes” was carried out according to the BT type - by removing the track chains.

In the regions of the Russian Federation and foreign countries floating conveyors are used when eliminating consequences natural Disasters, floods and in rescue operations.
The PTS tracked amphibious transporter is designed for amphibious transport of artillery systems, wheeled and tracked. artillery tractors, armored personnel carriers and cars when crossing water barriers.
Together with a floating trailer on a hook, the PTS transporter also ensures the simultaneous landing of artillery systems and their tractors. On land, a floating trailer is transported by towing on a hook or on the loading platform of a conveyor.
With special equipment, the conveyor can be used in marine conditions.
The main parts of the PTS conveyor: body, power unit, power transmission, chassis, screw propellers and rudders, special equipment, electrical equipment and communications.
The conveyor is divided into three sections: control section, power section and cargo compartment.
Department of Management located in the transporter cabin, located in the bow of the hull. It contains the seats of the driver (on the left) and the commander of the conveyor (on the right), levers and pedals of the conveyor control drives, a steering wheel for the drive and control of the rudders, a drive lever for controlling the ejector flaps, a central panel of the driver, a distribution panel, a battery switch, a gyro-semi-compass with a converter, a cylinder with an air release reducer, a fuel distribution valve, a manual fuel priming pump, a valve for releasing air from the fuel supply system, a relay regulator, a winch, a radio station, two intercom devices, a three-color alarm unit and an air blower. Above the crew seat in the cabin roof there are two access hatches with covers.
Power department located in the lower part of the body (under the cargo compartment). It houses the engine, fuel and oil tanks, oil pump, oil and water radiators, air cleaner, heater, distribution box with main clutch and starter, gearbox, planetary turning mechanisms with brakes, final drives, cardan shafts, drive shafts propellers, large bilge pump, cab heater and starter relay. Torsion bar suspension shafts of the chassis run along the bottom of the power compartment inside the transverse beams. In the bottom under drain plugs components and assemblies power plant And power transmission there are hatches with covers. To drain water from the conveyor there is drain valve. On top, the power compartment is covered with roadway tracks and removable hoods and grilles.
Cargo compartment located in the power department. It contains two tracks, forming loading platform for transported goods. The cargo compartment is limited at the front by the rear wall of the cabin, at the sides by the sides of the hull and at the rear by a folding side. At the rear wall of the cabin there are rechargeable batteries. The following are mounted on the outside of the vehicle: a wave guard, headlights, side lights and a towing device. The propellers and rudders are located in the stern.

It is equipped diesel engine model B-46-5, with a power of 710 l/s, has an individual torsion bar suspension, capable of accelerating on the highway up to 60 km/h. The capacity of its tanks is 1090 liters, and its cruising range on the highway is 500 kilometers.
The movement of this conveyor through the water is ensured by two propellers, which have the function of working together with the scrolling of the tracks. Maximum speed PTS-2 when crossing water obstacles by swimming is 11.7 km/h. dimensions conveyor:
- Length - 11990 millimeters.
- Width - 3300 millimeters.
- Ground clearance - 400 millimeters.
The mass of the floating conveyor is 24,200 kilograms. For loading various equipment its tailgate is made opening, it is equipped with a winch driven by the main power unit. The carrying capacity of the PTS-2, both on land and on water, is 12 tons; in the front part there is a three-seat control cabin equipped with a heater and an air blower.
Floating conveyor PTS 2: use cases
You can buy PTS 2 inexpensively from the Perspektiva company. This equipment is now successfully used both in the armed forces, but also in civilian life, for transporting people, various goods and cargo to areas where ordinary trucks simply cannot pass due to the presence of water barriers and the lack of bridges. The price for PTS 2 is low, this conveyor is distinguished by the fact that it is very reliable, it is easy to maintain, and operation usually does not cause any problems.

Floating conveyor PTS
The floating transporter PTS is designed for crossing wide water barriers of personnel, wheeled vehicles, artillery systems and materiel. For simultaneous crossing of the artillery system and the tractor, the vehicle includes a PKP wheeled floating trailer. In this case, the artillery system is transported on a trailer, and the tractor is transported on a conveyor.
The transporter can also be used to transport personnel and cargo over rough and swampy terrain.
Loading capacity on water is 10 tons (with a buoyancy reserve of 30%), while transporting by land is 5 tons.
The transporter can be used during amphibious landing operations. For this purpose, it is equipped with a gyro-compass. Additional marine equipment (exhaust extensions, cabin glazing protection, sealed awning, two powerful bilge pumps ensures seaworthiness up to 4-5 points.
In one flight, the transporter can transport (options): 2 85-mm cannons with crews, guns and howitzers of caliber from 122 to 152, one each with crews, 12 wounded on stretchers, 72 soldiers with full weapons, 2 UAZ-469 vehicles, a car from UAZ -452 to Ural -4320 (without cargo).
Loading is done on land through a folding tailgate with ramps. Opening and closing the tailgate is carried out using two manual mini-winches. But the ramps have to be folded back and raised manually.
Self-propelled vehicles drives into the body self-propelled, non-self-propelled equipment is pulled into the body by a conveyor winch driven by the base engine.
The predecessor of PTS was crawler transporter K-61, further development PTS-2. Modernization of PTS - PTS-M was equipped diesel heater cabin and body, which increased the vehicle’s capabilities when operating in winter conditions, eliminated the possibility of ice freezing on the sides of the vehicle.

Movement on water is carried out using two screws. The propellers can be activated simultaneously with the drive of the tracks, which increases the vehicle’s capabilities when entering/exiting water and moving through shallow water. The maximum permissible river flow speed for machine operation is 3 m/sec. Thanks to the extremely low specific ground pressure, the machine has good maneuverability through wetlands. Winch drive from base engine provides full possibility of self-extrication of the machine when stuck or overcoming steep climbs.
PTS were in service in the airborne transport company of the engineer battalion of the motorized rifle (tank) division - 1 platoon (9 vehicles); in a separate transport and landing battalion of the district - 2 companies (36 vehicles).

To load the artillery system onto the trailer, he leaned back, and the artillery system was rolled onto the trailer using the PTS winch. PKP trailers were supplied to GPT units based on half of the unit’s vehicles.
From the author. With a trailer, the PTS became completely uncontrollable on the water. Such a combination could operate satisfactorily only on stagnant water (in lakes, ponds). That's why they were never used.
