Caterpillar sells landfill compactor at WasteExpo

Caterpillar, Peoria, Illinois, handed the keys to its 836K landfill compactor to Kenneth Burkett, founder of American Waste Control, Tulsa, Oklahoma, during WasteExpo 2017 at the Ernest N. Morial Convention Center in New Orleans on May 9.

American Environmental Landfill (AEL), the American Waste Control-owned landfill that will use the compactor, takes in around 2,500 tons per day of mostly industrial waste and construction and demolition debris, Todd Green, vice president of landfill operations at AEL, said during a press conference at the event.

The 836K landfill compacter that was on display at the Cat booth during WasteExpo will be delivered to American Waste Control. It will be the company’s first time using the Cat model.

The 562 gross horsepower compactor features autoblade technology, designed to automatically raise the blade when the machine reverses and lowers the blade to a preset height when it moves forward. The STIC steering controller uses a single lever for steering and transmission control.

The 836K' s Cat C18 Acert engine uses selective catalytic reduction designed to control nitrogen oxide emissions and the Cat Clean Emissions Module, including a diesel particulate filter (DPF), diesel oxidation catalyst and Cat Regeneration System, to control particulate emissions. DPF regeneration is automatic and does not interrupt the machine's work cycle. An autoreversing, hydraulically driven fan is deisgned to adjust its speed to match cooling requirements.

Cat's Impeller Clutch torque converter works with a throttle-lock feature designed to allow modulation of rimpull in order to slow the machine without reducing engine speed. This capability is designed to allow full hydraulic power for blade and steering functions at all ground speeds. A direct drive/converter drive power shift transmission and rugged planetary axles complete the 836K's drive train.

The 836K can come equipped with one of three new wheel and tip configurations to meet certain applications. The new paddle tip is designed to create less fuel burn with more traction and less weight. The plus tip has a traditional design made for increased side slope stability and the combination tip is designed to merge both paddle and plus tips for side slope stability.

To protect key components and systems from damage, the 836K uses specialized guarding, including hydraulically actuated engine and power-train shields, front-frame guards to prevent trash build-up inside the frame and to protect hydraulic lines and axle-seal guarding to stop material from binding around the axles. In addition, sight gauges and fill tubes are protected.

The air-inlet screen uses a vertically corrugated, fine-mesh design that assists in preventing trash from entering the radiator area. Striker bars located in front of and behind the rear wheels and behind the front wheels help keep wheels free of debris and assist in maintaining required compaction. In cohesive material or severe packing conditions, optional cleaner fingers are available to further assist wheel-tip cleaning.
