Overview

Designed with durability built in, the Cat 815K ensures maximum availability through multiple life cycles. Designed and manufactured for optimum performance and serviceability, this rugged, powerful machine delivers heavy-duty compaction and dozing.

  • POWERFUL EFFICIENCY

    • Advanced Productivity Electronic Control System (APECS) delivers improved transmission shifting performance and a higher level of comfort for operators.
    • Decelerator Pedal acts as a brake, transmission neutralizer and an engine decelerator to override the engine speed selected by the throttle lock. Allows the operator to slow speeds when the throttle lock is engaged and to return to throttle lock without pressing a resume or set button.
    • Electro Hydraulic Controls increase productivity with responsive implements feature. Operate comfortably with easy-to-use soft-detent controls.
    • Steering System provides confident machine operation and precise control enabled by the 815K's load sensing hydraulic steering system.
    • Increased efficiency with variable displacement piston pumps that give operators precise positioning for easy maneuvering in tight areas with 42 degree articulation in each direction.
    • Steering and Transmission Integrated Control System (STIC™) enhances operator comfort by integrating steering and transmission control functions in a single lever. Includes finger-controlled gear selection.

  • LONG TERM VALUE AND DURABILITY

    • Designed and made with purpose-built structures to remain safe and durable for the long run.
    • Long-life-designs ensure multiple life cycles and ability to withstand the toughest conditions.
    • Full box-section rear frame resists torsional shock and twisting forces.
    • Heavy-duty steering-cylinder mounts efficiently conduct steering loads into the frame.

  • PERFORMANCE WITH LESS FUEL

    • Deep system integration of new engine and emissions system, power train, hydraulic system and cooling system. It all adds up to lower fuel consumption and improved emissions control.
    • Advanced Productivity Electronic Control System (APECS) delivers consistent, smooth shifting and efficiency through integrated electronic controls.
    • Strategic use of metallurgy and heat treating ensures long-life gears.
    • Cat C7.1 engine Is designed for maximum fuel economy and increased power density.
    • Two engine options are available to meet Tier 4 Final/Stage IV or Tier 3/Stage IIIA equivalent emissions standards (depending upon market).
    • Engine features innovative Cat electronics, fuel injection process, air-management systems and aftertreatment with Cat Selective Catalytic Reduction. And, automated aftertreatment regeneration eliminates need for operator attention.
    • Integrated systems intelligently lower working engine speeds and reduce overall system heat loads resulting in improved performance and fuel efficiency.
    • Next generation fuel injection systems control fuel metering through a series of carefully timed microbursts providing cleaner combustion and the most efficient fuel burn.

  • OPTIMIZE COMPACTION

    • Chevron Tamping Tip Design provides greater ground pressure, more compaction, excellent traction and a smooth ride.
    • Compaction is achieved from the bottom of the lift to the top. The tapered tips walk out of the lift without “fluffing” the soil. The top of the lift is compacted and the surface is relatively smooth and sealed so hauling units are able to maintain a high speed when traveling over the fill.
    • The 815K travel speed delivers four forces of compaction: pressure, manipulation, impact and vibration.
    • This compactor also spreads fill, potentially reducing the number of spreader tractors needed for the project.
    • Symmetrical Tamping Tip Pattern delivers equal compaction in forward or reverse. Tips are full perimeter and replaceable.
    • Two cleaner bars on each wheel keep drums free of carryover dirt, in forward and reverse, maximizing efficiency. Cleaner bars are available with standard or abrasive tips depending upon the application. Bars are adjustable and bar tips are heat-treated and direct-hardened cutting-edge steel to increase life.

  • OPERATOR COMFORT AND CONTROL

    • Pressurized cab sits on isolation mounts improving comfort and reducing sound.
    • Cab features a convenient floor storage tray/lunch box.
    • Cat Comfort Series III Seat includes mid-back design, thick, contoured cushions, air suspension, six-way adjustments, and a seat-mounted implement pod and STIC steer that moves with the seat for optimal control.
    • Control Panel gives operators the information and controls for safer and time-saving settings.
    • STIC control simplicity provides maximum responsiveness and control with STIC that combines directional selection, gear selection and steering into a single lever.

    Read More

  • PRODUCTIVITY WITH TECHNOLOGY

    • Cat Compaction Control system uses Machine Drive Power (MDP) technology to measure rolling resistance and correlates it with soil stiffness. MDP works in both cohesive or granular soils. Optional 3D mapping system maps compaction measurements to the precise location the operator is working, providing a real-time view of progress, and a record of compaction uniformity.
    • DETECT technologies help keep people and equipment safe by keeping operator aware of the work area and by monitoring and reporting unsafe conditions, like avoidance zones.
    • COMPACT technologies combine advanced compaction measurement, in-cab guidance and reporting capabilities to help you consistently meet compaction targets fast, uniformly, and with fewer passes.
    • Cat Product Link is deeply integrated into your machine, giving you access to information like machine location, hours, fuel usage, idle time and event codes via the online VisionLink user interface. Helps effectively manage fleet and lower operating costs.

  • BUILT-IN SAFETY FEATURES

    • Railings, ladders and non-slip surfaces enhance technician and operator safety.
    • Design ensures three points of contact at all times through ground level or platform accessible service areas.
    • Rearview camera with in-cab monitor increases operator awareness around the machine.
    • Standard cab-mounted LED warning strobes.
    • Optional heated mirrors ensure enhanced visibility for safe operation.
    • Optional LED lights provide excellent workspace visibility.
    • Reduced vibrations to the operator with isolated cab mounts and seat mounted implement and steering controls.
    • Low interior sound levels.
    • Pressurized cab with filtered air.

  • REDUCE ENVIRONMENTAL IMPACT

    • Engine Idle Shutdown can help you save fuel by avoiding unnecessary idling.
    • Reduce waste to the environment with maintenance-free batteries.
    • High speed oil change ensures fast, easy, and secure changing of the engine oil.
    • The 815K is built to be rebuilt, maximizing machine life, and minimizing environmental impact. Get the most from your investment, with our sustainable options including Cat Reman and Certified Rebuild programs. With these programs, remanufactured components deliver cost savings of 40 to 70 percent, lowering operating costs while also reducing waste and minimizing the need for raw materials.
