Overview

Cat Soil Compactors are designed with durability built in, ensuring maximum availability through multiple life cycles. With optimized performance and simplified serviceability, our machines allow you to operate more efficiently and safely. Representing a long-standing commitment to quality and performance, this rugged, powerful machine is designed and built for heavy-duty compaction and dozing operations. Focused on helping our customers succeed, we have continued to build upon each new series. The 815K continues our legacy of reliability, performance, safety, operator comfort, serviceability, and efficiency.

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.
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.
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.
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.
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.
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.
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.

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.
