Atlet ARRV is designed for solution of a wide range of technical support tasks of tank units while performing all types of military operations under various weather and climatic conditions. It enables to solve the following tasks:
Atlet ARRV is used in the composition of repair and recovery groups in the rear of tracked convoys when conducting a march, DVAPs, units and formations, recovery groups during fording operations, maintenance points, etc. They strengthen mobile maintenance means of tank battalions, division mechanized brigades and other units and formations, equipped with heavy tracked equipment.
In its layout Atlet ARRV is divided into three isolated compartments:
Sections with auxiliary power unit with welding equipment and cooling system, hydraulic panels of add-on equipment, auxiliary winch and battery section as well as fuel system tanks are arranged outside on the fenders.
The engine-transmission compartment of Atlet ARRV is unified with ETC of the basic tank and differs from it by availability of power take-off for functioning of add-on equipment.
ETC comprises a twin-stroke, multi-fuel in-line six-cylinder liquid cooled diesel engine and reduction gear for the add-on equipment arranged in the engine compartment. 1000 and 1200 hp engines can be fitted in the power pack.
The engine, by means of gear clutch, is connected with two planetary gear boxes that ensure torque transmission to the sprocket wheels.
The engine air supply system is of three-stages. The first stage is an inertial grid, the second and third stages is a cyclone-cassette type air cleaner with dust ejection.
Air cleaning degree is 0.998%. The power pack cooling system is liquid, closed, of ejection type and exhaust gases operated.
Reversible gear boxes that ensure pivot turn, with seven forward and five reverse gears can be fitted on the vehicle. Gear boxes are controlled frictionally, hydro-mechanically by means of two distribution gears arranged on the gear boxes housings.
The machinery space, middle section of the vehicle, houses main winch, add-on equipment drives reduction gear, fuel and hydraulic systems tanks, preheater system boiler and other equipment. Main traction winch provides for recovery of the damaged, sunken and stuck tank and vehicles with traction force of 25 t, and with the help of pulley blocks for two and three branches - 50 and 75 tons respectively.
The winch is arranged inside the hull and connected with the main engine through the drives reduction gear with cut-off mechanisms.
The rope is delivered angularly to the vehicle axis through the rotary delivery unit in the hull front part. In the “travelling” position the delivery unit is covered by the tight casing.
The drives reduction gear, with hydraulic pumps arranged on it, ensures functioning of add-on and auxiliary equipment with the main engine running and cuts-off the main winch drive.
The manned compartment in the hull front part houses Atlet ARRV crew working stations, control drives, instrumentation equipment, life-supporting systems and SPTA set.
The hull front part contains driving compartment with controls, Atlet ARRV movement systems instrumentation equipment, dozer and crane controls and driver’s seat in it. All basic controls are unified with similar systems of the basic tank and do not require additional retraining and adaptation while training of drivers.
In lay out, the commander’s station is combined with the driving compartment with the handler’s seat into one space. It holds means of communication and instrumentation equipment of NBC agents detection system, commander’s sighting-observation complex arranged in the hatch with guidance drives similar to the ones of the basic tank. The complex comprises: TKN-5 commander’s sight with in-built night channel, anti-aircraft mount PZU-7 sight and guidance panels, periscopic single magnification TNPO-160 type observation devices. It also houses means of communication and navigation as well as the Atlet ARRV systems control units and inner set of SPTA.
The handler’s seat is arranged at the left side of the manned compartment near the commander’s seat. Under certain circumstances it can be used to accommodate the required specialist or other servicemen (commander, crew member from the recovered tank, etc.). FFE, HPC (hydro-pneumatic cleaning of observation devices) equipment, SPTA set, heater installation and other equipment is fitted in the handler’s sector.
The Atlet ARRV running gear is totally unified with the tank running gear and has seven rubberized road wheels and three rubberized support wheels at each side. Hydraulic shock absorbers are arranged on the first, second and sixth elements of suspension. For installation on Atlet ARRV the running gear has been modified for fitting the suspension actuators while operating with dozer and crane equipment. The suspension actuator device in “travelling” position is arranged on the right fender.
The caterpillar track with parallel rubber-metal pin and rubber pads in two variants - steel one with grousers and rubber-padded shoes can be supplied with Atlet ARRV. Such suspension ensures high speed of movement both on the paved roads up to 70 km/hr and cross-country up to 45 km/hr.
With the purpose to save the engine life and to ensure operation of the add-on equipment with the main engine not running, the auxiliary power unit (APU) is installed on Atlet ARRV. The APU ensures operation of the crane, welding equipment, auxiliary winch, dozer equipment, charging equipment and operation of the electric equipment of Atlet ARRV at the stops. The unit comprises 30 hp D-120 engine that is interlocked through the reduction gear with the hydraulic pumps block and connected to the welding generator. It is installed on the left fender in the isolated box. There is an access to the box through the two doors. The APU filling capacity is 40 liters. The unit cooling system is combined, of electrical-hydraulic type, fan-driven and is arranged behind the APU in a single, separated by the bulkhead section.
Atlet ARRV is equipped with an auxiliary winch with traction force of up to 900 kg to provide for delivery of the main winch rope, pulling of pulley blocks and other cargo handling works.
The winch is located on the left fender inside the isolated box. There are two holes for operation, maintenance, repair, installation/removal. The winch delivery unit is arranged on the front hatch. The winch is hydraulically driven from the driver’s seat inside the hull.
Atlet ARRV is fitted with crane equipment for lifting-transportation operations while repairing, restoring the vehicles and semi-lifting the tank during repair of its running gear. The load at the crane hook is up to 25 t. To provide its revolutionary movement the crane is installed on the rotary platform.
Maximum crane jig swinging angle is up to 750. Operation of the crane equipment powered by the main or auxiliary engines ensures replacement any of the engines as well as replacement of other equipment on Atlet ARRV itself. The crane equipment can be controlled both from the driver’s station and remotely from outside the vehicle at the distance of up to 5 m. With the help of crane equipment it is possible to remove and install the turret, engine, transmission, running gear elements, top deck plate and other elements and systems of the serviced tank as well as other equipment. For operation of the crane equipment it is necessary to level the ground, deactivate suspension by means of attached supports and use the dozer as an outrigger. In the inoperative condition the hook buckle is stored on the right fender. Canvas cover protects the crane roller block with ropes from soiling and precipitations.
To perform earthworks - excavation of caponiers, arrangement of DVAPs (damaged vehicles assembly positions), preparation of access and exit roads, covering up of ditches, trenches for passage of the equipment Atlet ARRV is fitted with dozer equipment. The dozer can also act as an outrigger during lifting-transportation works and as an anchor while operating with the main winch.
The dozer equipment is hydraulically driven by hydraulic pumps, main engine or auxiliary one and controlled from the driver’s station.
