816K Landfill Compactor

Cat Landfill 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. Introduced in 1972, the 816 has been the industry leader for over 40 years. Focused on helping our customers succeed, we have continued to build upon each new series. The 816K continues our legacy of reliability, performance, safety, operator comfort, serviceability, and efficiency.

Efficiency and Productivity

Advanced Productivity Electronic Control System (APECS)

The new APECS is designed to improve transmission shifting performance, providing a higher level of comfort for the operator and increasing productivity.

Decelerator Pedal

The left pedal acts as a brake, transmission neutralizer and an engine decelerator to override the engine speed selected by the throttle lock. This enables the operator to slow down when the throttle lock is engaged and to return to throttle lock without pressing a resume or set button again. This aids in maneuvering around trucks, tractors or any other obstacle.

Steering System

Confident machine operation starts with precise machine control enabled by the 816K’s load sensing hydraulic steering system.

  • Increase efficiency with our variable displacement piston pumps
  • Achieve precise positioning for easy loading in tight areas with 42 degrees each way of steering articulation
  • Enhance operator comfort with integrated steering and transmission control functions

Electro Hydraulic Controls

Operators increase productivity with our responsive implements feature.

  • Operate comfortably through electronically controlled hydraulic cylinder stops
  • Handle easy-to-use soft detent controls

Structures

The 816K is specifically designed and made with purpose built structures to remain safe and durable for the long run. Advanced design, materials and robotic welding contribute to increased durability and overall machine strength.

Robust Structures

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

Engine and Power Train

Cat Planetary Powershift Transmission

Building your success begins with a best-in-class transmission.

  • Consistent, smooth shifting and efficiency through integrated electronic controls that utilize Advanced Productivity Electronic Control System (APECS).
  • Long life and reliability through heat treat gear and metallurgy.
  • Two forward and two reverse speeds.

Engine and Emissions

The Cat C7.1 ACERT engine is designed for maximum fuel efficiency and increased power density. Two engine options are available to meet Tier 4 Final/Stage IV or Tier 3/Stage IIIA equivalent emission standards. This engine features innovative Cat electronics, fuel injection process, air-management systems, aftertreatment solution with Cat Selective Catalytic Reduction, and a fuel efficient regeneration system. The Cat Regeneration System automatically removes soot from the Diesel Particulate Filter without interrupting your machine’s work cycle.

Efficient Systems and Components

Innovative systems intelligently lower the average working engine speeds and reduce the overall system heat loads which result in significantly improved performance and fuel efficiency.

Advanced Systems with Innovative Integration

The deep system integration of the new engine and emissions system, power train, hydraulic system and cooling system result in lower fuel consumption on average compared to previous models.

Next Generation Fuel Systems

Cat injection timing precisely controls the fuel injection process through a series of carefully timed microbursts, providing more control of combustion for the cleanest, most efficient fuel burn. On the 816K the high pressure common rail fuel systems boost performance and reduce soot for the C7.1 ACERT engine.

Cat NOx Reduction System

The Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes it back into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.

Aftertreatment Technologies

To meet the additional 80% reduction in NOx emissions required by Tier 4 Final/Stage IV emission standards, one new system, the Selective Catalytic Reduction (SCR), has been added to the already proven Cat Tier 4 Interim/Stage IIIB aftertreatment solution.

Wheels and Tips

New Long Life Paddle and Plus Design Compactor Tips

Providing up to 40% longer life than previous offering.

Designed specifically to compliment Cat machines.

Improving machine performance!

  • Longer wear life

Integrated Technologies

Cat Connect makes smart use of technology and services to improve your job site efficiency. Using the data from technology-equipped machines, you’ll get more information and insight into your equipment and operations than ever before.

Cat Connect technologies offers improvements in these key areas: Equipment Management – increase uptime and reduce operating costs. Productivity – monitor production and manage job site efficiency. Safety – enhance job site awareness to keep your people and equipment safe.

LINK Technologies

LINK technologies wirelessly connect you to your equipment, giving you valuable insight into how your machine or fleet is performing so you can make timely, fact-based decisions that can boost job site efficiency and productivity.

Product Link™/VisionLink®

Product Link is deeply integrated into your machine, giving you access to timely information like machine location, hours, fuel usage, idle time and event codes via the online VisionLink user interface can help you effectively manage your fleet and lower operating costs.

Rear Vision Camera

A rear vision camera greatly enhances visibility behind the machine to help the operator work more productively. Work with greater confidence and at peak potential while keeping people and assets safe.

COMPACT Technologies

COMPACT technologies combine advanced compaction measurement, in-cab guidance, and reporting capabilities to help you consistently meet compaction targets fast, uniformly, in fewer passes – saving on fuel and rework.

Cat Compaction Control

The factory-installed Cat Compaction Control system uses the Cat Compaction Algorithm to measure effective compaction value and deliver real-time 3D pass mapping guidance to the cab, indicating where to work and when layers are compacted to optimum density. Pass mapping helps eliminate voids, optimize cell space, and document results. VisionLink 3D Project Monitoring provides landfill managers with detailed compaction analysis to more effectively monitor and manage their operation.

Waste Protection

Guarding

Working in the toughest application, the purpose built 816K Landfill Compactor has specialized waste guarding to protect key components and systems from damage, debris, chemicals, premature wear, or wrapping of the material around components. This additional guarding includes:

  • Engine and Power Train Guards – Guards help prevent trash build-up and shield components.
  • Front Frame Guards – Front frame guards prevent trash build-up inside the frame. This guard further protects components and hydraulic lines.
  • Axle Wrapping and Seal Guarding – The guarding prevents material from wrapping and binding around the axles, as well as assist in ease of cleaning.
  • Major System Guarding and Sight Gauges – Transmission oil tube is guarded to resist damage from debris. The sight gauge for the transmission is visible from ground level. The fuel tank is positioned away from the debris in the front frame and is easily accessed.
  • High Radiator Air Inlet with Screen – Helps prevent trash from entering the radiator area, maintaining proper airflow and allows for debris to fall off.
  • Striker Bars and Optional Cleaner Fingers – Striker bars are located in front of and behind the rear wheels and behind the front wheels. Striker bars help to keep wheels free of debris to assist the wheel tips in maintaining good compaction. In cohesive material or severe packing conditions, optional cleaner fingers are available to further assist in keeping the wheel tips clean.
  • Extended Roof – An oversized roof extends past the cab doors and windows to minimize debris build up.
  • Suction Fan – Allows ambient air to cool, providing better cooling capacity. It also pressurizes the engine compartment, preventing trash build up.
