XCMG Official Mining Roadheader Boring Machine EBZ200A
EBZ200A roadheader is designed as a compact structure, low body, low centre of gravity. easy operation, good working performance.
1、Electric control system
EBZ200A roadheader adol11ts flameproof and intrinsically safe switch box and control box with small size, lightweight, flexible operation, which is safe and reliable: the main controller is installed in a closed casing that can effectively block out electromagnetic interference; the working condition is shown with LCD screen, menu mode is used for operating interface with flexible and safe parameter setting; it is equipped with functions such as overvoltage, motor overload, open-phase, short circuit, over-temperature and earth leakage lockout.
2、Hydraulic system
The hydraulic system of EBZ200A roadheader adopts transfer case, several pumps control, with main hydraulic components coming from international brands.
3、Cutting head
The cutting head is optimized by utilizing simulation technique and picks come from Kennametal Co., Ltd. With the reasonable layout and strong rock breaking capacity.
4、Spraying system
Spraying system of EBZ200A roadheader include inside and outside spray systems, of which the front is after-pick spraying which is used to strength outside spraying, the latter is reasonable in design and equipped with a leakage detection function.
5、First freighter
The straight structure is adopted for the first freighter, which can achieve smooth lapping with haulier bed and transportation.
6、Traveling mechanism
The travelling mechanism is a high integration of internationally advanced motor and reducer, whose big output torque can adapt to operations with large dip angle.
If there is a limit for weight or total weight during transportation, it can be disassembled for transportation.
