Specifications
Working on a range of height of cut
of up to 19m within a radius of
24m, the 4800XPC also offers a
maximum dump reach of 19.4m, with a
dumping height of 10.8m. The machine offers
an operator eye level of 10.1m, tail swing
radius of 16.2m and floor level radius of
16.2m. The machine comes in 15.2m in
length, a width of 15.0m, and a height of
14.7m (over the gantry)
Mechanical Versatility
The digging machine readily has a full
suite of service products and
consumables available, including wire
rope, GET, crawler shoes and more with
mechanical upgrades, repair and rebuild
services are available worldwide. According
to Komatsu, “Our focus on modular
component design means more efficient
maintenance and upgradability. This emphasis
on ease-of-maintenance, combined with the
traditionally rugged P&H mechanical systems
and increasingly smart, fast control systems,
translates into some of the most reliable,
productive loading machines in the mining
industry today”
The direct-drive crowd with integral fleeting
sheave on the machine reduces maintenance
costs and helps eliminate boom jacking whilst
optimized boom design with stabilized handle
geometry improves dipper manoeuvrability
and maintenance access. The enhanced ring
gear resists fatigue and accommodates
increased payload. It comes with:
A wide twin-leg handle for
stability through the dig cycle.
A geometry optimized for
fatigue resistance in shock
and high-load conditions.
Maximized cutting forces for
improved fill factors and cycle
times.
Komatsu describes the machine as a reliable
machine of high availability which can
consistently achieve over 90% mechanical
availability with proven mining duty motors
and gearboxes for extended component lives
and a structural design that uses high-strength,
low-alloy steels for improved fatigue lives. It
has rugged components that includes dualhoist
motors for balanced and evenly
distributed loads, DELTA drive for improved
shoe-to-tumbler engagement, and planetary
transmissions with proven long life on swing
and propel (over 20 million hours logged).
The digging unit comes with highly precise
motor controls due to the existence of rugged
centurion-based compact-design ABB drives,
direct torque control with the best dynamic
performance, AC drives that are compact, aircooled,
and modular, maintenance-friendly
modules that are easy to replace, monitored
and controlled neural network of over 500 I/O
nodes, using fast, high-capacity Profibus fiberoptic
cable network and optimized shovel
performance for maximum production rates.
The PreVail remote health management
(RHM) system provides timely and efficient
machine health and performance data. The
PreVail RHM system taps into the powerful
communication, command, and control
capabilities of the shovel's electrical control
system, transforming the data into valuable
knowledge, including KPI (key performance
indicator) dashboards, graphical analysis
tools, predictive modeling, and reporting
tools.
There is
no
shadow
of a
doubt
that the
Efficiency and
Operator Comfort
he rresponsive control system offers
Tthe operator confidence throughout the
digging cycles. The clean graphical
user interface displays shovel systems
operation and health information whilst the
high visibility enabled and efficient sight lines
with refined ergonomics (adjustable heated
seat, massage controls, adjustable lumbar
support, and two-position footrest) improve
operator effectiveness and reduce fatigue.
So well ergonomically designed is the
operator cabin that loading control joysticks,
brake and propel transfer functions are easily
at operator's fingertips, and dipper trip and
signal horn trigger switches reduce operator
fatigue and repetitive strains.
Filtered air comes through the house
pressurization system for cooling and dust
repression. The P&H 4800XPC just like its
family members features hand-operated hoist,
crowd, swing and propel control joysticks
feature thumb-actuated auxiliary switches for
siren, dipper trip functions. There is also
convenient access to shovel control buttons,
switches mounted to the left, right consoles
flanking operator. Safety of the operator is
enhanced by the modular counterweight and
boarding stairs which are also easy to
assemble and disassemble.
The included Mine Air Systems (MAS)
climate control system provides air
conditioning, heating, air filtration, and
pressurization for your electric mining shovel.
The design takes into account careful thought
on modular design for unmatched change-out
speed and convenience, unique weather-sealed
roof-plate eliminates dust and water leaks into
the cab and electrical room, stainless steel
construction, designed specifically for ozone
friendly R-407C refrigerant, high-efficiency
air filters to suit each application, industrialsized
extra-efficient filter/pressuriser with air
pre-cleaner, smooth and quiet scrolltechnology
compressor and enhanced dipper
design which provides improved bank
penetration and higher payload-to-weight
ratio.
Komatsu P&H4800XPC
is a beast in the mining load and
haul fraternity and it has been unleashed.
