Efficiency and Productivity

Efficiency with Eco Mode
The Eco Mode when active allows the machine to go into auto-shift when machine is not operating at maximum torque conditions. This feature will automatically shift from 1st gear to 2nd gear with a capped engine top speed. The feature senses the need for ground torque and will upshift and downshift accordingly, optimizing performance and thus saving fuel. This feature can be easily enabled or disabled on the soft keypad.

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.

  • Built for multiple lives, the Cat 826 is one of the most rebuilt products to achieve the second and third life to get the most value from your investment. 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 while benefiting the environment.
  • 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.

Waste Protection

Working in the toughest application, the purpose built 826K 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 - Hydraulically actuated 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.
  • Air Inlet Screen - The vertically corrugated, fine mesh, air inlet screen helps reduce trash from entering the radiator area 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 step tips in maintaining good compaction. In cohesive material or severe packing conditions, optional cleaner fingers are available to further assist in keeping the wheel step tips clean.
  • Extended Roof - An oversized roof extends past the cab doors and windows to minimize debris build up.
  • Under Hood Ventilation System - Creates a neutral pressure environment to prevent trash ingestion from hood openings while providing fresh air to the alternator, electronics and turbo.
