Working in the toughest application, the purpose built 836K 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 – The hydraulic tank, the hydraulic system oil tube, and transmission oil tube are guarded to resist damage from debris. The sight gauges for the hydraulic and transmission are easily 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 traction. 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.
