844K

Frames

Your key to maximum uptime and productivity is our purpose built front and rear frames.

• Full box-section frames absorb torsional forces during dozing, maintaining alignment for hitch pins and drive line.
• Spread hitch design features double tapered roller bearings and hardened pins that resist both horizontal and vertical loads.
• Enhance strength in key pin areas through the use of one piece castings.

Steering and Transmission Integrated Control System (STIC™)

Experience maximum responsiveness and control with STIC that combines directional selection, gear selection and steering into a single lever.

• Simple side-to-side motion turns machine right or left, minimizing operator movements.
• Easy to operate finger controlled gear selection.
• Smoother, faster cycles and less operator fatigue through the use of low effort integrated controls.

Cat C27 Engine

Durability and efficiency powering your 844K comes from the Cat C27 Engine. Optimum performance is built in through the use of a 12 cylinder, direct injection design.

• Optimized performance and quick engine response with an electronic control module.
• Reliable efficiency with complete control over injection timing, duration and pressure with Mechanically Actuated Electronic Unit Injection (MEUI™).
• Extended engine life and improved fuel efficiency with reduced rated speed.
• Designed to meet U.S. EPA Tier 4 Final or Tier 2 Equivalent emission standards.

Blade Response

Improve operator efficiency by matching the speed of the blade movement to your application.

• Three different speeds: Standard, Fine and Fast.
• Easily configured through the advisor display.
• Only affects blade raise and lower functions.

Your operators can work more efficiently and stay comfortable with our customer-inspired cab features.

Cat Comfort Series III Seat

Enhance comfort and reduce operator fatigue with Cat Comfort Series III seat.

• High back design and extra thick, contoured cushions.

We can help you succeed by ensuring your 844K has design features to reduce your downtime.

• Longer service intervals on fluids and filters.
• Safe and convenient service with ground level or platform access and grouped service points.
• Swing-out doors on both sides of the engine compartment provide easy access to important daily service checks.
• Ecology drains for ease of service and prevention of spilling potential environmental contaminants.
• Centralized remote pressure taps.
• Reduce downtime with VIMS system notifications so your operators and technicians can resolve any problems before failure.

Sustainable Benefits

Sustainability is designed and built into our 844K's features.

• Engine Idle Shutdown can help you save fuel by avoiding unnecessary idling.
• Reduce waste to the environment with our maintenance free batteries.
• The 844K is built for multiple lives. To assist with maximizing machine life, Caterpillar provides a number of sustainable options such as our Reman and Certified Rebuild programs. In these programs, reused or remanufactured components can deliver cost savings of 40 to 70 percent, which lowers operating cost.
• Caterpillar offers retrofit packages to bring new features to older machines, maximizing your resource. And, when you go through the Cat Certified Rebuild program, these retrofit kits are part of the rebuild process.
