EQUIPMENT RELOCATION
Convenient Modularity for Quick Assembly
For quick relocation over long distances, the Cat high-
wall mining system can be taken apart in modules. Rapid
disassembly and reassembly is facilitated by convenient
hydraulic and electrical connectors, and all modules are
sized for transport using regular public roads.
Depending on local conditions, the system can also
be transported between sites and without disassembly
by heavy haul trucks.
SAFETY
Designed with Safety as the First Priority
The Cat highwall mining system is engineered and
equipped with a priority on safe operation; safety fea-
tures include:
●
Elevated Cab with Cameras
— For a complete view
of the highwall mining system and mining opera-
tion, the FOPS certified operator cabin is elevated
on the machine and three magnetic base cameras are
provided whose positions can be easily and quickly
adjusted.
●
Above-ground Operation
—Operation of the system is
performed entirely on the surface with no crew mem-
bers working underground.
●
Small-crew Size
— The highwall mining system only
requires a three- to four-person crew for full operation.
●
Remote Operation
— In an emergency, the machine
can be operated remotely using a laptop from as far
away as 61 m (200 ft).
●
Anchoring System
—Two drills mounted on the front
of the machine are used to drill into the pit floor up
to 2.4 m (8 ft). High-strength pins are then inserted
through the base frame into the pit floor to help stabi-
lize the machine and to maintain its accurate position,
even under tough pushing and pulling conditions.
●
Methane Sensor
—A methane sensor is mounted near
the cutter drum. When the methane content in the air
reaches the warning level, an automatic warning sig-
nal attends the crew. When the methane level reaches
a pre-set maximum level, a warning signal attends
the crew, and all electric power to the cutter module
is automatically disconnected (Except to the methane
sensor itself). Settings depend on local regulations.
●
Working safely at night is enhanced by a number of
LED Flood lights, as well as LED platform and inte-
rior lights. The platform and interior lights are backed-
up by a battery system to stay on for up to 10 minutes
after a power outage.
●
Hydraulic Controls
—Underground hydraulic valves
are provided with flame proof solenoids.
SUPPORT
Product Support
Parts and service support for the HW300 are never
far away with the global Cat Dealer Network. You can
count on our dealers’ skill and knowledge for qual-
ity maintenance and high parts availability. Since the
machine will be serviced on site, this requires a trained
crew with a dedicated maintenance truck, stocked with
essential spares and consumables for the machine. Your
dealer is happy to discuss this and other support services
options.
Training
Caterpillar can arrange operational and technical
training which covers every aspect of the HW300Highwall
Miner.
Support Equipment
The highwall miner has the following support equip-
ment needs:
1. Two wheel loaders; one to load push beams during
mining, one to manage the coal stock pile.
2. A stacker belt is recommended for managing the coal
as it comes off the machine.
3. Equipment requirements for keeping the seam exposed
will depend on the application.
