Technical description

 

Basic design


Surface Miner for cutting rock with mechanically driven cutting drum and a two-part conveyor system.


Frame


Rigid welded design with integrated tanks for fuel and water.


Crawler unit suspension


The four crawler tracks are mounted free-floating on parallelogram-type suspensions. The tracks are fitted with double grouser track shoes.


Cutting depth control


The height is adjusted via hydraulic cylinders. The rear crawler suspensions are controlled via an automatic cutting control unit.


Travel drive


Each crawler unit is driven by a planetary gearing with hydraulic motor. Both the front and rear travel drive motors

Cutting drum


The cutting drum rotates in an upcutting direction. The cutting tools are mounted in toolholders welded onto the body of the drum. The tools used, i.e. number, arrangement and type of tools, depend on the machine's momentary use and on the properties of the material being cut.


Cutting drum drive


The cutting drum is driven via a mechanical clutch on the flywheel side of the diesel engine, transmission belts and a planetary gearing installed in the cutting drum. The cutting speed can be adjusted in line with the momentary application by replacing the pulleys for the transmission belts.


Steering


The Surface Miner is steered via an all-crawler steering.


Water spraying system


The water spraying system largely prevents the generation of dust while cutting material and reduces the degree of wear on the cutting tools due to the cooling effect. The spray nozzles can easily be removed for cleaning. Spray nozzles are additionally installed for the loading conveyors, thus preventing the generation of dust while loading the material.


Soundproofing


The engine, cooling unit and hydraulic system are soundproofed to reduce the noise level and protect both the operating crew and the environment.


Operator's cab


  The Surface Miner is equipped with a closed, sealed and soundproofed cab. The driver's seat is rotatable and is equipped with armrests into which all the most important controls have been integrated. Air-conditioning and heating are standard features of the cab. For the machine's transport the operator's cab can be folded by 180°.


Conveyor system

The conveyor system comprises a wide primary conveyor which picks up the cut and comminuted material at the cutting drum, as well as a discharge conveyor to discharge the material onto trucks. The discharge conveyor can be adjusted in height and slewed to both sides. The conveying speed can be infinitely varied.


Safety


Comprehensive safety equipment with five Emergency OFF switches.


Transport


The Surface Miner can be disassembled into two modules for transport. The first module comprises the frame, operator's cab, power station, primary conveyor and crawler tracks. The second module comprises the belt suspensions, the turntable and the discharge conveyor.
