Technical description
Basic design
The 2200 SM is a Surface Miner with a
mechanically driven cutting drum and
two-part slewing front-end discharge
conveyor of variable height. The machine
travels on crawler tracks.
Chassis
Robust welded construction with
mounts for the individual function
modules and superstructures. The
tanks for diesel fuel and water are integrated
into the chassis. The hydraulic fluid tank forms a separate unit.
Together with an engine hood which
automatically opens hydraulically and
service doors which open wide on the
right and left-hand sides, the optimally
arranged individual components ensure
easy access for maintenance and
servicing.
Operator's platform
The walk-through operator's platform
with access ladder on each side is located
in the middle part of the machine.
It is equipped with two separate
control consoles which can be pivoted
and vertically adjusted. Both control
consoles and the right-hand driver's
seat can be displaced outwards beyond
the edge of the machine.
The controls are conveniently located
within the operator's field of vision. The
operator's platform includes a display
of the Wirtgen information and diagnosis
system for monitoring the operating
status of the machine. The ergonomic
sitting position, clear overview and
elastically prung floor of the operator's
patform help to make operation of
the machine simple and conenient. The steering and feed control operate
with proportional action and are controlled
via joysticks.
As an option the machine can be
equipped with an operator's cab.
Wirtgen information and diagnosis system and instruments
The Wirtgen information and diagnosis
system WIDIS 32 provides the driver
with comprehensive up-to-the-minute
information on the current status of the
engine and hydraulic system and generates
visual and acoustic alarms
when necessary. The data and messagesappear on a multi-function display
(LC display) on the operator's
platform. Such data as operating
hours, engine speed, engine temperature
or battery charge, can also be
viewed there.
The pressure in the hydraulic system is
additionally monitored by two pressure
gauges on which the momentary
pressure in 12 different parts of the hydraulic
system can be read off.
The two air filters and the filters in the
hydraulic system are monitored electronically.
Drive unit
The machine is driven by a modern V12 engine with a power rating of 811 PS and meeting the stringent emission standards of the US Environment Protection Authority (EPA).It is equipped with an all-electronic motor management system with which the engine automatically adjusts to changing ambient conditions, such as different atmospheric pressure, temperature or humidity. In addition, the engine also ensures maximum torque stability even with extreme engine compression, thus preventing breaks in operation. The extremely large radiator surface ensures that the engine is efficiently cooled so that the machine can safely be operated even in high outdoor temperatures. The drive additionally includes a fan controller. The fan speed is reduced at low ambient temperatures and low loads, thus reducing the noise levels. All service work on the engine can be carried out from the ground.
Soundproofing
Soundproofing is a standard feature
and reduces the level of noise generated,
thus protecting both the operating
personnel and the neighbourhood
from noise.
Cutting drum drive
The cutting drum is driven mechanically
by the diesel engine via a shifting
clutch and power belts acting on the
drum gear. Due to their width, the three
power belts each with five ribs ensure
optimum power transmission and a
long service life. The belts are automaticallytensioned by a hydraulic
cylinder.
Cutting drum
The cutting drum rotates against the
feed. Toolholders accommodating the
round-shank cutters are welded onto
the body of the drum. Neatly milled
edges are ensured by special edge
segments. Additional ejectors ensure
that the cut material is efficiently transferred
to the loading belt. If the material
is to remain on the ground, a flap
on the scraper blade ensures that it is
deposited in windrows between the
crawler tracks. For these purposes a
cut material guiding device is available,
preventing the tracks from wearing.
The drum housing is made of wearresistant
material (Brinell-hardness
HB 400).
Tool changes
The scraper blade opens hydraulically
to provide access to the cutting drum
for tool changes, which can be carried
out in a comfortable working position.
Storage areas for the toolboxes are
provided. Crawler tracks/adjustment of the
machine height
The crawler tracks are suspended
from the chassis via round cylinders,
the height of which can be adjusted
hydraulically. The height of each
crawler track can be adjusted individually.
The height required for the cutting
depth is adjusted via the two
cylinders at the front, while the rear
crawler tracks form a full floating axle.
The large lift ensures considerable
ground clearance simplifying such difficult
manoeuvers as reversing or loading
and unloading the machine from a
low-bed truck.
Travel drive
The Surface Miner is equipped with
large crawler tracks (5 HD) lined with 2-
grouser steel crawler shoes and driven
by separate hydraulic motors. The
traction drive motors are fed by a common
variable displacement hydraulic
pump. The crawlers are hydraulically
tensioned.The automatic drive makes it unnecessary
to change over between
cutting and driving gear. The speed
can be infinitely varied from zero to the
high maximum speed. A switchable
hydraulic fuel distributor acts as differential
lock and ensures uniform traction
even under difficult conditions.
When the machine has travelled at a
particular speed, that speed can be
saved in a "Tempomat" and reused after
changing trucks, for example.
Automatic power control
The machine is equipped with an automatic
power control which adjusts
the rate of advance in accordance with
the load on the diesel engine, but
which can also be deactivated.
Steering
The machine has a fingerlight hydaulic
all- rack steering with proportional
action (can be operated from the
right or left-hand side of the operator's platform). The front and rear crawler
tracks are steered separately via joysticks.
The steering function is decoupled
from the height adjustment by specially
designed steering rings. Large steeringangles permit an extremely small
turning circle.
Brakes
Braking is achieved by drag from the
hydrostatic transmission. The Surface
Miner is additionally equipped with
two automatic multiple disk parking
brakes at the front.
Loading system
The reclaimed material is transported
to the truck (front-end loading) by a
wide conveyor system comprising a
loading belt and a discharge belt.
The gradation control beam largely
prevents the material being cut from
breaking into large slabs and simultaneously
protects the loading belt
against premature wear.
The discharge belt delivers the material
at a great height and can be slewed
to both sides. The height can be adjusted.
This ensures optimum adaptation
to the conditions prevailing on
site. The high conveying speed and
1,100 mm wide, V-ribbed steep-incline
conveyor belts ensure that the material
is discharged rapidly.
The conveyor system is designed and
built in such a way as to permit easy
replacement of the belts.
Milling depth contrl /Automatic
level control
The Surface Miner is equipped with an
electronic automatic level control system
for controlling the cutting depth. It operates by proportional action, i.e.
changes in the height of the reference
plane are compensated rapidly and
without overshooting by the machine.
The reference planes can be scanned
by various methods, e.g. via a cable
sensor on drum shields at the sides,
via an ultrasonic sensor on thesurface,
via a grade line in combination
with rotary transducers or via a plane
formed by lasers. A slope sensor is also
available on request; the required
connections are included as tandard
equipment.
The multiplex system, which compensates
longitudinal unevenness, can
likewise be integrated into the automatic
level control system if desired.
Hydraulic system
Independent hydraulic systems for
travel drive, conveyr belts, fan drive
for the radiator, water spray system
and control functions (cylinders). The
hydraulic pumps are driven by the
diesel engine via a transfr gearbox.
The entire system is filtered via a return
line suction filter. The oil for the control
functions (cylinders) is additionally
passed through a pressure filter.
Electrical system
24 Volt system with starter, 3-phase
alternator and two 12 V batteries, as
well as socket outlets for lamps.
Water spray system
The formation of dust clouds during
the cutting process is largely prevented
by a hydraulic water spray system,
which also cools the round-shank cutters,
thus considerably extending their
tool life. The spray nozzles can easily
be removed for cleaning. The tank is
generously dimensioned so that the
work need onl be interrupted occasionally
for refilling.
Fillers
Water is filled via C-pipe connections
or large filler ports. Disel is refilled via
large ports.
Safety features
Retaining lugs ensure that the machine
can be tightly secured to a low-bed trailer or loaded by crane. The comprehensive
working and safety lights
ensure thatthe working area is well illuminated
and the work can proceed
safely, even in inclement weather. Furthermore,
a lamp with magnetic base
which can be positioned anywhere,
ensures e.g. a safe tool change.
