Roadheader EBZ-55 от "CoalMachGroup"It is used for mining of coal, mixed faces the fortress of rocks less than f = 5, as well as the workings of softwood and construction of utility tunnels. Roadheader can cut, load and transport the rock mass simultaneously with loading railcars, conveyor belts and motorized belts. Harvester has a compact design, low center of gravity, easy to manage, has great potential in the destruction of the manual control of the breed. Roadheader has a configuration corresponding to a high international level, internal and external control systems with dust. Gearbox and hydraulic suspension combine integrated and highly integrated. The middle part of the transport system has a joint and a large dump height. The combine has an LCD display with a demonstration of the functions in the dynamics, easy to manage and maintain. Comprehensive electrical protection higher than the national standard.

The hydraulic system of tunnel boring machine has the function to maintain a constant pressure in the hydraulic system, the pressure in the line contour cutting and loading circuit is sensitive overload protection. The machine is widely used for drilling in different directions for tunneling faces the soft coal and mixed faces, for penetration of softwood. Also harvester used for laying railway tracks and roads, as well as for the installation of water reservoirs.

Removable cross-sectional area from one position - 13.5 m², a longitudinal tilt angle ± 17º. The optimum height for the job - 2,1-3,2 m.
