Benefits
Execute Efficiency
- The new tractor hydraulic on-demand fan helps assist in lowering fuel consumption.
Integrated Cat Technologies
- Monitor, manage, and enhance job site operations.
- Product Link™ collects machine data that can be viewed online through web and mobile applications (optional attachment).
- Access information anytime, anywhere with VisionLink™ – use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve safety and security on your jobsite.
- Shorten the learning curve for inexperienced operators with Sequence Assist.
Easy to Operate
Designed for Safety
- Get in and out of the cab easier with the new powered access ladder system (optional attachment).
- Enhance an operator’s awareness of the site surroundings with the optional Work Area Vision System (WAVS).
- Seat belt indicator provides visual and audible alerts when the seat belt is not in use.
- The advanced cushion hitch enables the cushion hitch to prevent end stroke by having the ability to predict end stroke events and manage the rate of dampening, resulting in reduced hitch maintenance and improved operator ride in rough conditions.
- The fuel fill, fuel filter, engine oil filter, engine oil change, and water drain are easily accessible at ground level.
Work in Comfort
Be More Productive
- Large-size capacity coal scraper bowl to accommodate low-density loose coal.
- Advanced productivity electronic control system (APECS) allows the engine and transmission to communicate on a high level. This communication allows the machine to utilize better the power and torque the engine is producing. The 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 replaces top gear selection, allowing the machine to find the correct gear that works best for the engine and transmission. Pulling the load in the correct gear, in most cases, results in a lower engine load factor and lower fuel burn.
- Auto-stall assists in quickly bringing the transmission to an operating temperature at startup when the machine is working in a cold climate region.
Purpose-Built Coal Bowl
Integrated Cat Technologies
Easy to Operate
- The spacious cab features easy, intuitive controls and excellent visibility. The cab provides a comfortable working environment for all-day operations.
- Cat advanced ride management (ARM) seat suspension reduces end stroke movement of the load cylinder for a smoother ride.
- 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's speed by canceling the throttle command and engaging the engine compression brake.
Work in Comfort
- Reduce up to 14 individual operator commands per cycle with sequence assist.
- Steer with less effort using the newly designed high-pressure steering system.
- Enjoy interior improvements and a more ergonomic work environment with a 21% larger cab than the G Series cab.
- Intuitive, ergonomic controls keep operators focused on their work.
- Maintain desired cab temperature with automatic temperature control.
Be More Productive
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.
- The 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.
