EBZ300 roadheader for excavating rock is suitable for rock tunnel, semi-rock roadway and other geological conditions like relatively hard water tunnel and ore mining tunnel.
It adapts to the minimum cross-section of 10.6 square meter with a scraper conveyor, can achieve efficient excavation and transportation.
EBZ300 road header adopts explosive-proof and intrinsically safe switch box and intrinsically safe operation box which are small in volume, 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 has over-voltage, motor-overload, short circuit, and earth leakage lockout functions.
It is equipped with internal spraying system with good de-dusting effect. Hydraulic system is simple and convenient to maintain.
EBZ300 type road header adopts constant power, pressure cut off and load sensitivity control.
Cutting head is optimized with emulation technique; cutting tooth layout is reasonable and rock breaking capacity is strong.
Spraying system of EBZ300 type road header consists of internal spraying system and external spraying system. Internal spraying system is to spray behind teeth. It possesses water leakage detecting function. Design of external spraying system is effective.
First conveyor adopts straight structure and is connected with insertion board smoothly. The conveying operation is unobstructed.
Traveling driving system integrates motor and reduction gear with internationally advanced technology. 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 roadheader can be dis-assembled to transport.
