Electronic Control System
EBZ200 road header adopts explosive-proof and intrinsically safe switch box and intrinsically safe operation box which are small in volume, light in weight, flexible in operation, safe and reliable; main controllers are mounted in a sealed shell to shield electromagnetic interference effectively; working conditions are displayed on LCD screen, it adopts menu type operation interface and it is flexible and safe to set parameters; it possesses, overvoltage, motor overload, phase loss, short circuit, over-temperature and earth leakage lockout functions etc.
Hydraulic system of EBZ200 type road header adopts constant power, pressure cut off and load sensitivity control. Main hydraulic components adopt products of world famous brands.
Cutting head is optimized with emulation technique; cutting tooth adopts products from Kennametal Corporation; its layout is reasonable and rock breaking capacity is strong.
Spraying system of EBZ200 type road header consists of internal spraying system and external spraying system. Internal spraying system is to spray behind teeth so strengthen external spraying system; design of external spraying system is reasonable.
First conveyor adopts straight structure and forms four-connecting rod sliding with insertion boards; changes of length of scraper chain of first conveyor is small when insertion boards are lifted up or placed at the bottom.
