Features at a Glance

Purpose-Built Coal Bowl: Purpose-Built Coal Bowl
• Large capacity coal bowl scrapers are longer and higher than
standard open bowl scrapers.
• Purpose-built coal bowl dual engine scrapers deliver faster cycle
times with maximum payloads.
• High ground speed provides the ability to manage stockpiles.
• Machine is designed for loading, hauling, and compaction for
complete functionality.
• Work effectively in poor underfoot conditions and climb slippery
piles and loose coal with all-wheel drive (AWD).
• Coal bowl scrapers provide effective coal compaction, which
reduces the risk of spontaneous combustion in coal stockpiles by
eliminating the air spaces.
• Specialty coal bowl scrapers are optimized for maximum machine
productivity and efficiency.

Be More Productive

Be More Productive

The Advanced Productivity Electronic Control System (APECS)
    enables communication between the engine and transmission to
    effectively optimize power and torque output. This integration
    results in enhanced efficiency with a net result is moving more
    material.
Use Ground Speed Control to set the desired top speed and the machine will find the gear that works best for the engine and the transmission, providing a lower fuel burn.
The machine speed limit feature allows the machine to maintain a
set top speed instead of relying on top gear selector.
Auto-Stall assists in quickly bringing the transmission to an
operating temperature at start-up when the machine is working in a cold climate region.

Work in Comfort

Work in Comfort

Steer with less effort with the newly designed high-pressure steering
system.
Reduce up to 14 individual operator commands per cycle with
Sequence Assist (optional attachment).
Enjoy interior improvements and a more ergonomic work environment

The fuel fill, fuel filter, engine oil filter, engine oil change, and water drain are easily accessible at ground level.

Easy to Operate

Easy to Operate

Engine overspeed protection will automatically engage with no operator input when the machine is in eighth gear. The machine will assist in slowing the machine speed by canceling the throttle command and engaging the engine compression brake.
The spacious cab features easy, intuitive controls and excellent visibility. The cab provides a comfortable working environment for all-day operation.
