EBZ320 roadheader is designed as compact structure, low body, lowcenter of gravity. easy operation, good working performance.

1、Electric control system

EBZ320 roadheader adol11ts flame proof and intrinsically safe switchbox and control box with small size, light weight, flexible operation, which issafety and reliable: main controller is installed in a closed casing that caneffectively block out electromagnetic interference; working condition is shownwith LCD screen, menu mode is used for operating interface with flexible andsafe parameter setting; it is equipped with functions such as overvoltage,motor overload, open-phase, short circuit, over temperature and earth leakagelockout.

2、Hydraulic system

The hydraulic system of EBZ320 roadheader adopts transfer case, severalpumps control, with main hydraulic components coming from international brands.

3、Cutting head

The cutting head is optimized by utilizing simulation technique andpicks come from Kennametal Co., Ltd. With reasonable layout and strong rockbreaking capacity.

4、Spraying system

Spraying system of EBZ320 roadheader include inside and outside spraysystems, of which the front is after-pick spraying which is used to strengthoutside spraying, the latter is reasonable in design and equipped with leakagedetection function.

5、First freighter

Straight structure is adopted for first freighter, which can achievesmooth lapping with hauler bed and transportation.

6、Traveling mechanism

The traveling mechanism is a high integration of internationallyadvanced motor and reducer, whose big output torque can adapt to operationswith large dip angle.

If there is limit for weight or total weight during transportation, itcan be disassembled for transportation.
