Caterpillar upgrades 836 landfill compactor

May 11, 2023
Stronger axles and transmission

The 836 Caterpillar landfill compactor has upgraded axles and transmission for increased durability. The torque converter with lock-up clutch eliminates torque converter losses while lowering system heat and transfers more power to the ground for improved traction. Its advanced productivity electronic control system (APECS) transmission control helps the compactor to achieve greater momentum on grades and delivers fuel savings by carrying momentum through shift points.

The Cat 836 features larger diameter shafts and Cat locker differentials for enhanced drive system longevity, improved direction shift speed, and increased traction in the waste stream. Updates to the final drive gear set reduce stress and enhance pitting life of the gear. A new fan motor guard helps to prevent bag wrapping, and a 5-inch higher efficiency fuel filter delivers cleaner fuel to the engine.

The Cat C18 engine provides 562 gross horsepower, and an improved radiator air inlet door sealing and carry over pressure hood enclosure help to reduce the need for engine compartment cleanout.

Landfill compactor technologies

Cat Compact technologies combine advanced compaction measurement, in-cab guidance, and reporting to enable the operator to meet compaction targets uniformly and in fewer passes. The system includes a global navigation satellite system (GNSS) receiver on top of the 836 and mapping display inside the cab.

Standard Cat Compact with Pass Mapping delivers high-accuracy pass counting, allowing operators to monitor areas of coverage and number of passes on the 10-inch display. Optional Compact Elevation Mapping combines both pass counting and elevation monitoring of slopes to plan, control layer thicknesses, and achieve better density.

Most major components are accessed from ground level or on the machine’s platform for safety during servicing. Sight gauges for coolant, transmission, and hydraulic oil provide a quick visual inspection. Increased guarding around the axles mitigates risks of damage to components.

Cab enhancements include a lowered glass design to improve forward visibility to the blade and wheels, and a rearview camera increases visibility to the machine’s rear. The cab is pressurized for operator comfort and 72 dBA interior sound levels. The steering and transmission integrated control (STIC) combining steering, gear selection, and other functions into a single lever.

Five wheel and tip configurations are available. The lighter paddle tip design delivers high performance and traction with less fuel burn, and the plus tip traditional design increases stability on side slopes. The combination tip wheel incorporates both the paddle and plus tips to provide performance and fuel economy along with side slope stability.
