Cat 816K landfill compactor continues a fine tradition

0

Caterpillar’s new 816K landfill compactor builds on the established performance, durability, and reliability that the model 816 has demonstrated since 1972. The new K Series model, designed with heavy-duty main structures that support multiple lifecycles, features a fuel-efficient Cat C7.1 ACERT engine, single-lever steering, pressurized cab, and wheel/tip options that provide extended service life.

The foundation of the 816K’s purpose-built design is its massive, robotically welded main structures, featuring a full box-section rear frame that resists torsional shock and twisting forces, heavy-duty steering cylinder mounts to efficiently transmit steering loads into the frame, and an axle-mounting design that is optimized for increased structural integrity.

Three new wheel and tip configurations allow matching the 816K to the application: the Paddle Tip reduces weight and provides high performance with reduced fuel burn; the Plus Tip provides increased side-slope stability; and the Combination Tip provides an effective compromise of performance, fuel economy, and side-slope stability.

In addition, specialized guarding protects components from damage, debris accumulation, chemicals, and premature wear, including axle guarding that prevents material from wrapping and binding around the axles. The transmission oil tube is guarded, and the fuel tank is positioned away from debris in the front frame. A screened air inlet for the radiator is placed high at the rear of the machine to prevent debris from blocking airflow, and the grille’s design allows trash to fall away. Striker bars are designed to keep wheels free of debris, and optional cleaner fingers are available for use in cohesive soils and in material that packs between tips.

The 248hp (rated power) C7.1 ACERT engine meets Tier 4 Final/Stage IV emissions standards with advanced technologies that do not interrupt the machine’s work cycle. An engine-idle-shutdown system saves fuel by eliminating excess idling. The 816K’s Caterpillar-built planetary powershift transmission features special metallurgy and gear heat-treating to ensure long-term durability.

The transmission’s Advanced Productivity Electronic Control System (APECS) is designed to improve transmission shifting performance, provide a higher level of operator comfort, and increase production. Heavy-duty planetary axles complete the power train, the front is fixed and the rear oscillates ±6°.

The 816K’s Cat STIC (Steering and Transmission Integrated Control) combines steering and transmission control (directional and gear selection) into a single lever. Simple side-to-side movements of the low-effort lever provide precise steering maneuvers through 42°of articulation right and left. Electrohydraulic implement controls use soft detents, and cylinders use electronically controlled stops for smooth operation. The left pedal serves as a brake, transmission neutralizer, and decelerator that overrides the engine-speed setting.

The operator’s environment is kept clean via filtered air that pressurizes the cab, and temperature is maintained with an automatic climate-control system. The cab is isolation- mounted to reduce vibration, and operator comfort is enhanced with an air-suspension seat or the available Cat Comfort Series III seat. Backlit membrane switches have LED indicators and ISO identification, and a standard rearview camera system enhances operator awareness.

The 816K is designed for multiple machine lives and component rebuilds utilizing Caterpillar sustainable options such as the Reman and Certified Rebuild programs. These options could save a customer up to 70% of purchasing a new comparable machine by reusing components or replacing with manufactured components.
