Bulldozers

Kirovets К-702MBA-01-BKU

Wheel dozer. Operating weight 20.8 t. Equipped with angled blade 3800 mm wide in the dozer position and angled blade 3650 mm wide in the grader position.

Its main advantage over crawler dozers is high travel speed (up to 30 km/h), allowing it to quickly move to different dozing activities (layer-by-layer cutting and digging, leveling, movement of rocks, soil, loose materials).
 
This type of dozers is used for the following tasks:
 
  • construction, maintenance and repair of roads (groundwater, logging, snow, snow and icy, etc.);
  • Stripping and mining works in quarries (sand, coal, etc.);
  • Maintenance of areas around “big” excavators and loaders when loading trucks in quarries;
  • Joint work with loaders to move bulk materials, such as crushed stone export terminal.
  • clearing of blockages after the collapse or demolition of buildings;
  • construction of embankments;
  • excavation;
  • laying of trail roads on virgin snow;
  • clearing of roads from snow and snow retention;
  • Clearing of ditches;
  • Loosening of 3-4 category soils, for example, during the reclamation of forest land under temporary roads built for exporting of wood.
For quarry works, the dozer can be fitted with tires with the increased quarry protectors and blade reinforced with HARDOX steel. Air conditioner is included.
For more efficient clearing of snowy roads the dozer can be additionally equipped with wedge-shaped blade with drawbar hitch. Blade is made of cold-resistant steel, blade width is 3160 mm, blade height is 1200 mm. An important advantage of this configuration is pivot post, allowing to change the direction without turning around on the road (this is very important when working on winter roads, since you do not have to pull off the winter road to turn around).

 

WAD (wheel angle dozer) consists of a base tractor and dozer equipment, including a dozer blade, rippers, c-frame, hinges and hydraulic drive. Wheel dozer allows to move soils with the direct or deployed blade (blade U-turn is provided in two planes: horizontal and vertical).
 
Due to all-wheel drive and articulated frame of the base tractor, WAD has excellent maneuverability, which allows to efficiently work in the toughest road conditions. This model of the wheel dozer can be used very effectively in the complete absence of the road, i.e. for its creation.
 
Wheel angle bulldozer is able to work in different climatic conditions at the temperature of -40 ° C to + 40 ° C.
 
Warranty period is 18 months or 2000 running hours.

CABIN

Two-seat, full metal, with thermal, vibration and noise isolation, with integrated safety frame to protect the machine operator from rollover (ROPS). Hydrostatic steer loader, adjustable steering wheel, instrument panel with automatic control over the operation of the loader systems can reduce the operator’s fatigue. All controls are conveniently placed, sprung driver's seat. Two blowers for the front and rear windows, tinted windows. Two heaters.
