Main characteristics of this machine are: compact structure, short machine body, low center of gravity, convenient operation and stable when working. Cutting head is driven by motor without strong overload capacity. All components are reasonably designed to be small part combination for the convenience of underground transportation and installation. It is equipped with internal spraying system with good de-dusting effect. Hydraulic system is simple and convenient to maintain.

Hydraulic System

EBZ75 type road header adopts constant power, pressure cut off and load sensitivity control.

Cutting Head

Cutting head is optimized with emulation technique; cutting tooth layout is reasonable and rock breaking capacity is strong.

Spraying System

Spraying system of EBZ75 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

First conveyor adopts straight structure and is connected with insertion board smoothly. The conveying operation is unobstructed.

Traveling Mechanism

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.
