XCMG Official Mining Roadheader Boring Machine EBZ200A
EBZ200A road header is designed as a compact structure with a low body and low center of gravity. Easy operation, good working performance.
Electric control system
EBZ200A road header contains a flameproof and intrinsically safe switch box and control box with small size, lightweight, flexible operation, which is safe and reliable: the main controller is installed in a closed casing that can effectively block out electromagnetic interference; the working condition is shown with LCD screen, menu mode is used for operating interface with flexible and safe parameter setting; it is equipped with functions such as overvoltage, motor overload, open-phase, short circuit, over-temperature and earth leakage lockout.
Hydraulic system
The hydraulic system of the EBZ200A road header adopts a transfer case with several pump controls, with main hydraulic components coming from international brands.
