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.
