Power of the power plant engine B46-6 780 horsepower allows for the IMP-2 confidently overcome the destruction and debris, providing cross-country capability at the level of the main tank T-72. This engineering reconnaissance vehicle (IMR) was created to perform the most difficult tasks of making passes in minefields and debris in the conditions of direct fire exposure of the enemy. The design is based on the chassis of the tank, which guarantees high survival of the crew and the ability to work in areas of radioactive contamination.
Performance bulldozer Telescopic boom and telescopic boom directly depends on the serviceability of the hydraulic system and the qualification of the operator. The machine is able to move huge volumes of soil, to roll down trees up to 1 meter in diameter and dismantle concrete structures. The reliability of the chassis nodes allows you to use IMP-2 as a tractor for towing damaged equipment weighing up to 30 tons.
The basis of the chassis is the chassis of the medium tank. T-72AThis ensures the unification of spare parts with the main line of armored vehicles. A tracked propulsion system with rubberized support rollers reduces noise and increases patency on soft soils. The system of individual torsion suspension allows the machine to maintain stability when the manipulator works on rough terrain.
The power plant is presented with a 12-cylinder V-diesel B-46-6 with direct fuel injection. The engine life before major repairs is a significant number of motor hours, which is critical for long-term engineering operations. The transmission includes a manual gearbox with planetary rotation mechanisms and onboard frictions.
A system is provided for operation in smoke or chemical contamination conditions. filter-ventilation. The air is cleaned of radioactive dust, aerosols and poisonous substances before being fed into the habitable compartment. The tightness of the hull allows the crew to work safely in areas with high radiation backgrounds.
⚠️ Attention: When working in the overload mode of the hydraulic system, it is necessary to strictly control the temperature of the oil, since overheating can lead to a failure of the actuators.
Compound and habitable compartment
Crew IMP-2 The vehicle consists of two people: the commander of the vehicle and the driver, who are placed in the front of the hull in an isolated capsule. Workplaces are equipped with special seats with cushioning, reducing the impact of vibration and shock waves when driving over rough terrain. Visibility is provided by observation devices and periscopes located along the perimeter of the roof of the cabin.
The interior space is divided into traffic control zones and work equipment control zone. The control devices allow you to track the pressure in the hydraulic system, engine temperature and fuel level. A radio station is used to communicate with other vehicles, providing stable communication on the march and during parking.
- 🛡️ Armour protection: The frontal projection withstands hits of small-caliber shells and fragments of artillery ammunition.
- 🔥 Fire safety: An automatic fire extinguishing system has been installed, which is triggered when the temperature in the engine compartment increases.
- ❄️ Climate control: The heating and ventilation system maintains a comfortable temperature inside the cabin at any time of the year.
Access to the main components and assemblies is through roof hatches and side doors, which facilitates maintenance in the field. The layout of the machine is designed to minimize the time it takes to deploy the working equipment after a stop.
Bulldozer equipment and manipulator
The key element of the machine is bulldozerwhich may be in a transport and working position. In the transport position, the dump is raised and serves as additional protection for the frontal projection of the body. In the working position, it is lowered for soil planning, filling funnels and digging pits.
On the roof of the car mounted telescopic boom with a rotating platform, equipped with gripper (grafer) This device allows you to capture tree trunks, concrete blocks and other objects weighing up to 2 tons. The boom's departure and angle of rotation ensure operation in a wide sector without the need to move the machine itself.
☑️ Checking of working equipment
Manipulator control is carried out using joysticks and levers located at the operator’s workplace. The hydraulic system ensures smoothness of movements and high accuracy of positioning of the capture. The platform’s 360 degree rotation capability greatly enhances the machine’s functionality.
| Parameter | Meaning | Unit of measurement |
|---|---|---|
| Arrow load capacity | 2000 | kilogram |
| Maximum arrow-exit | 7.3 | ? |
| The width of the dump | 3.9 | ? |
| Lowering/uplifting time | 15-20 | sack |
⚠️ Attention: It is strictly forbidden to lift loads with a mass exceeding the established limit, as this can lead to the overturning of the machine or the destruction of the arrow.
Mine trawl and mine-clearance systems
To ensure safe movement in mine-explosive barriers IMP-2 It can be equipped with a KMT-7 gauge mine trawl. The trawl is hung on the front of the machine and is designed to neutralize anti-tank mines by pressing or crushing. The trawl design allows you to withstand the detonation of powerful explosives without loss of functionality.
The process of installing and removing the trawl takes minimal time and is performed by the crew using standard mechanization tools. The presence of a trawl turns an engineering machine into an effective means of reconnaissance and making passages in minefields. After passing the machine on the cleaned column, other types of equipment can follow.
- 💥 Principle of action: The pressure of the tracks and trawl wheels causes the detonation of mines, safe for the main machine.
- 🔗 Construction: It consists of two rolling mines connected by a rigid frame with the body of the machine.
- ⚙️ Compatibility: The KMT-7 trawl is unified with other engineering support vehicles based on the T-72.
The use of trawls requires strict compliance with the speed regime, since speeding can damage the elements of the trawl chassis. After passing the mined area, the trawls are usually dismantled to improve the speed characteristics on the march.
History of the KMT trawl
The first samples of track trawls appeared during the Second World War. Modern modifications such as the KMT-7 have been tested in local conflicts, proving their effectiveness against the most advanced anti-tank mines with pressurized fuses.
Maintenance and repair
Regular maintenance IMP-2 includes checking the levels of technical fluids, track tension and the condition of hydraulic hoses. Particular attention is paid to air and fuel filters, as work in dusty conditions quickly leads to clogging. Timely replacement of filters extends the engine life.
The hydraulic system requires periodic checks for leakage and the absence of air traffic jams. If leaks are detected, the sealing rings or hoses should be replaced immediately. The use of non-recommended grades of hydraulic oil can cause the failure of pumps and distributors.
The chassis is subjected to intense wear, so the condition of the supporting and supporting rollers, as well as the guide wheels, is checked after each exit to the terrain. The tension of the tracked tape is adjusted depending on the operating conditions and temperature regime.
Tip: To extend the life of rubber chassis elements in hot weather, it is recommended to make frequent stops for cooling, avoiding sharp turns in place.
⚠️ Attention: All work on repair of hydraulics should be carried out only after a complete reset of pressure in the system in order to avoid injuries.
