Roadheader EBZ-220H от Компании "CoalMachGroup" Roadheader EBZ-220H widely used for coal mining rock tunneling and in mines, rock hardness which is not more than 9. Harvester can realize the inconvenience of cutting, loading and transportation. Layout combine a compact, low center of gravity, easy to manage, it works perfectly, destroying hard rocks. Combine meet international standards of quality and safety. Equipped with a spray and cleaning system both inside and outside. The compact arrangement of the gearbox and the engine. Reducer working body and the motor are combined and highly integrated. The machine has an LCD display with a demonstration of the functions in dynamic, easy to manage and maintain. Standard electrical equipment higher than the national standards. The hydraulic system has a function of maintaining a constant pressure in the hydraulic system. The contour lines of the pressure in the cutting and loading circuit is sensitive overload protection. Compact size and easy control unit creates a significant safety at work. The processor used in several new patent technology. The machine is widely used in deep mines at large angles of incidence of soft coal seams, in the sinking of mixed faces and in tunneling for railways, highways and reservoirs. Removable largest cross-sectional area from one position - 27.5 m², a longitudinal tilt angle ± 18º. The optimum height for the job - 2,5-4.0 m.
