The transmission includes a manual transmission with synchronizers and on-board frictions. This scheme provides smoothness and high maneuverability, which is critical when working with a long arrow manipulator. Caterpillars have rubber metal hinges, which reduces noise and increases the life of the chassis.
Work equipment and manipulator
The main working body of the machine is bulldozer-leaning equipment and telescopic boom. Bulldozer dump can perform the functions of digging, grader and soil planning. The loosener allows you to open the frozen ground or asphalt covering.
On the roof of the hull there is a rotary platform with a telescopic boom. At the end of the arrow, a universal gripper. It allows the operator to capture objects of various shapes, dig trenches and perform installation work.
| Parameter | Meaning |
|---|---|
| Arrow load capacity | 2,000 kg |
| Maximum arrow-exit | 7.8 meters |
| Deep digging. | 4.2 meters |
| The width of the dump | 3.4 meters |
The control of the working equipment is carried out by the hydraulic system. The operator, being in the cockpit, can perform the most complex operations with high accuracy. Hydraulic ensures smoothness of movements, which is important when working with fragile or dangerous goods.
Protection and life support systems
Safety of the crew – priority 1 IMR-2. The body of the machine is sealed and equipped with a collective protection system. In the case of work in the area of chemical or radiation contamination, the air inside the cabin is cleaned with HPV filters.
The operator’s cabin and driver’s seat are equipped with individual air conditioning and heating systems. This allows you to work in extremely low or high temperatures. Radiation reconnaissance instruments Automatically control the level of pollution.
⚠️ Note: When working in the area of radioactive contamination, it is strictly forbidden to open the hatches without preliminary decontamination of the outer surface of the machine. A leakproofness violation can lead to the defeat of the crew.
Additionally, the machine can be equipped with hinged dynamic protection, although this is rare in the civilian sector. The main protection is the thickness of the armor and anti-atomic resistance of the glasses and seals. Fire extinguishing system It automatically responds to the temperature in the engine compartment.
☑️ Check before entering the infection zone
Modifications and civil applications
There are several modifications of the machine, among which IMR-2M and IMP-2M2. They are distinguished by improved ergonomics of the cabin, more powerful engine and improved hydraulics. Some versions are equipped with crane equipment of greater load capacity.
In the civilian sector, these machines are used where the heavy hand is needed. They are used to clear rubble after natural disasters, lay forest roads and even to clear snow in extreme conditions of the north. Universality allow for one IMP-2 A whole park of conventional construction equipment.
- 🏗️ Construction of roads in hard-to-reach areas.
- 🌲 Logging and wood trimming.
- 🏭 Elimination of accidents at industrial facilities.
- ❄️ Clearing snow drifts on highways.
Particular attention should be paid to the use of the machine in exclusion zones. There. IMP-2 performs works on the burial of radioactive waste and dismantling of structures. The robotic versions allow the operator to control the machine remotely while in a safe zone.
Maintenance and features of operation
Service IMP-2 requires high qualification of personnel. The engine and transmission need regular replacement of oils and filters. Special attention is paid to track-band and tension mechanisms that are experiencing enormous loads.
The hydraulic system requires the purity of the working fluid. Getting water or dirt can cause expensive pumps and hydraulic cylinders to fail. Regular inspection of seals and hoses is a mandatory procedure before each exit.
With prolonged operation of the manipulator, monitor the temperature of the hydraulic oil. Overheating reduces the viscosity of the fluid and can lead to a drop in pressure in the system.
The machine should be stored on hard areas using track stands for unloading rubber metal hinges. In winter, the engine is warmed up and hydraulics before starting work to avoid water shocks.
⚠️ Note: It is forbidden to use a machine to lift cargoes, the weight of which exceeds the passport carrying capacity at the maximum departure of the boom. This can lead to the car being overturned.
