OVERVIEW

BENEFITS

FEATURES AT A GLANCE

Move More with Less Fuel

New implement and steering variable displacement load sensing piston pumps.
Hydraulic flow now on demand, for improved fuel efficiency.

The Cat C7.1 engine is designed for maximum fuel efficiency and increased power density.

Features innovative Cat electronics, fuel injection process, air-management systems and aftertreatment solution (for Tier 4 Final) with Cat Selective Catalytic Reduction.
Innovative systems effectively lower the average working engine speed and reduce overall system heat loads for improved performance and fuel efficiency.
Deep system integration amongst engine and emissions system, power train, hydraulic and cooling system result in lower fuel consumption on average compared to the previous model.

Featuring all new Advanced Productivity Electronic Control Strategy (APECS) transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.

Long Term Value and Durability

Your bottom line is improved by highly durable structures that achieve multiple life cycles and withstand the toughest conditions.

Full box-section rear frame resists torsional shock and twisting forces.
Heavy-duty steering cylinder mounts efficiently transmit steering loads into the frame.
Axle mounting has been optimized for increased structural integrity.
Upper hitch pin, frame plate, and bearing size have been increased for longer life.

Push beams are through-width, not merely attached to side of frame.
In corner dozing, stresses are transferred and absorbed through a larger portion of the frame.

Built to Perform

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.

Building your success begins with a best-in-class transmission designed specifically for mining applications.

Consistent, smooth shifting and efficiency through integrated electronic controls that utilize Advanced Productivity Electronic Control Strategy (APECS).
Long life and reliability through heat treat gear and metallurgy.
Four forward and four reverse speeds to match your application.

The Cat C7.1 engine is designed for maximum fuel efficiency and increased power density. Two engine options are available to meet the emission standards for Tier 4/Stage IV or Brazil MAR-1 and China Nonroad Stage III, equivalent to Tier 3/Stage IIIA. The Tier 4 Final configuration:

Engine is equipped with a Selective Catalytic Reduction (SCR) system which injects DEF into the exhaust to reduce NOx emissions.
Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes in back into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.
While in operation, the aftertreatment will be seamless to the operator thanks to the passive regeneration system which is utilized.

Integrated Cat® Technologies

Integrated electronics provide flexible levels of information to both the site and the operator. This integration creates a smart machine and more informed operator, maximizing the productivity of both.

We have worked hard to help our customers and operators perform at their best through our newly upgraded touch screen information display.

Intuitive operation and easy navigation with our enhanced user interface.
Decrease service time by keeping operators informed about machine systems.

Take the guesswork out of asset management with Product Link remote monitoring.

Remote access to information through the easy-to-use VisionLink® interface.
Maximize uptime by staying informed on machine systems and diagnostic codes.
Track machine utilization and fuel usage.
Stay up to date on machine location, service meter hours, and reporting status.

Connect directly to the machine for access to a wide range of sensor information and enhanced machine data.

Create productivity reports with work cycle segmentation.
Identify operator training needs through productivity data.
Detailed data logging of machine parameters and diagnostic codes.
Track machine sensor information with trend analysis and histograms to monitor machine health.

Reduce Environmental Impact

Sustainability is designed and built into our 814K’s features.

Engine Idle Shutdown and Auto Idle Kickdown can help you save fuel by avoiding unnecessary idling.
Reduce waste generation with our maintenance free batteries.
The 814K 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.
The high speed oil change is standard and ensures fast, easy, and secure changing of the engine oil.

Purpose-Built Cat Attachments

Cat blades are resilient, durable and designed with excellent dozing and rolling characteristics.

Capacities and widths are set to achieve increased productivity.
Spreading design allows for spreading of cover material, as well as dozing of heavier loads.

The straight blade (2.8 m3/3.7 yd3) is designed for production dozing in stockpile material and general earthmoving. The coal blade (10.6 m3/13.8 yd3) is designed for precise and productive dozing while helping to retain load control with increased capacity for lighter materials. Wing angles help retain the load while dozing. This blade is available from Cat Work Tool and Services (CWTS).

Save on Fuel Costs

The 814K has several features to achieve greater fuel efficiency:

Load Sense Control Hydraulics – Provides only the hydraulic flow required by the implement and steering systems for improved fuel efficiency and greater rimpull.
Engine – Advanced engine controls maximizes power and efficiency.
Engine Idle Shutdown – Automatic engine and electrical system shutdown conserves fuel.
Advanced Productivity Electronic Control Strategy (APECS) – All new APECS transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.

Save on Service and Maintenance
