Main characteristics of this machine are: compact structure, short machine body, low center of gravity, convenient operation and stable work. Cutting head is driven by motor without strong overload capacity. All components are reasonably designed to be small part combination for the convenience of down-hole transportation and installation. It is equipped with internal spraying system with good de-dusting effect. Hydraulic system is simple; hydraulic components are made in China so that it is very convenient to maintain.
Electronic Control System
EBZ90 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
EBZ90 type road header adopts constant power, pressure cut off and load sensitivity control. Main hydraulic components adopt products of world famous brands.
Cutting Head
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
Spraying system of EBZ90 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; internal spraying possesses water leakage detecting function.
First Conveyor
First conveyor adopts straight structure and is connected with insertion board smoothly. The conveying operation is unobstructed.
Traveling Mechanism
Traveling driving system highly integrates motor and reduction gear with internationally advance technologies; its output torque is large and it is suitable for operation with large dip angle.
If there is limit on weight or overall height during transportation, the road header can be disassembled to transport.
