Front loader Kirovets K-702MBA-UDM2
Developed by order of the Ministry of Defense back in the early 1990s, UDM2 does not lose its relevance even now. According to the instructions of the military, the following capabilities were designed in this vehicle:
- development and movement of soil;
- construction of crossings through ditches and ravines;
- laying column tracks in areas with small forests, bushes and stones;
- laying column tracks through virgin snow;
- clearing roads from snow;
- arrangement of ramps to crossings;
- digging pits (on soil categories 1-3);
- loading bulk materials into vehicles;
- installation of embankments;
- filling ditches and holes.
The universal road machine consists of a basic tractor, loading and dozer equipment, thus combining the functions of a front loader and a wheel bulldozer.
The presence of a torque converter ensures favorable operation of the gearbox and engine when operating the machine in quarries or clearing roads of snow.

Front loader K-702MA-PK-6
The K-702MA-PK6 loader is designed to perform loading and unloading, earth-moving and transport work on soils up to category III, as well as bulk and lump materials with a density of up to 1.85 t/m3 (sand, loam, gravel, crushed stone, etc. ).The machine consists of basic and working equipment. The basic chassis includes a propulsion system with its systems, all elements of a hydromechanical transmission, wheel drive with drive axles, a system of wheel travel and parking brakes, and a control cabin. The following are mounted on the chassis: a pneumatic system, electrical equipment, a hydraulic steering system and part of the hydraulic system of the working equipment. The working equipment (loader) is installed at the rear of the machine and is a welded bucket hinged on the boom. The boom is attached to the portal frame. The articulated-lever system ensures that the hydraulic system operates at the required angle of inclination of the bucket during the process of raising or lowering the boom. The same system serves as an intermediate link for turning (tilting and tipping) the bucket using hydraulic cylinders.
