The new Cat 836 Landfill Compactor is designed for large-scale clearing jobs in harsh working environments. Engineering upgrades to the axles and transmission of the new landfill compactor help with durability of the heavy-duty main structures that support multiple life cycles.
The Cat torque converter with lock-up clutch eliminates torque converter losses while lowering system heat and transfers more power to the ground for traction. Its advanced electronic control system (APECS) transmission control helps the compactor to achieve momentum on grades and manages fuel consumption by carrying momentum through shift points.
Two configuration options for the Cat C18 engine powering the 836 allow the compactor to meet local emissions regulation requirements around the world. Radiator air inlet door sealing and carry over pressure hood enclosure help to reduce the need for engine compartment cleanout. Helping to facilitate maintenance planning, data captured alerts key personnel to the remaining useful life of the engine air filter.
Operation
Cat Compact technologies combine compaction measurement, in-cab guidance and reporting, so compaction targets are met. 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 pass counting, allowing operators to monitor areas of coverage and number of passes on the 10-in. (254-mm) display. Optional Compact Elevation Mapping combines both pass counting and elevation monitoring of slopes to plan, control layer thicknesses and achieve density.
Visualized remotely via VisionLink to support fleet management, standard Cat Link technology provides access to machine location, hours, fuel consumption, idle time, events and diagnostic codes. Operators are kept informed about machine operating conditions through a 3G touchscreen with a visual interface for viewing the vital information management systems (VIMS) data.
Maintenance
The new Cat 836 features large diameter shafts and Cat locker differentials for drive system longevity, direction shift speed and traction in the waste stream. Updates to the final drive gear set minimize stress and support pitting life of the gear. A new fan motor guard helps to prevent bag wrapping, while a new, 5-in. (127-mm) fuel filter delivers clean fuel to the engine.
The new compactor is designed for service and inspection with a focus on safety, as most major components are accessed from ground level or on the machine’s platform. Minimizing fluid contamination, sight gauges for coolant, transmission and hydraulic oil provide visual inspection. Guarding around the axles mitigates risks of damage to components. Leveraging VIMS data allows operators and technicians to resolve machine issues prior to failure.
Performance
The operator’s environment of the 836 includes forward visibility to the blade and wheels via the lowered glass design. Its standard rearview camera supports visibility to the machine’s rear. A pressurized, climate-controlled cab is built for operator comfort and provides low, 72 dBA interior sound levels. Combining steering, gear selection and other functions into a single lever, the Cat STIC (steering and transmission integrated control) delivers responsiveness and control.
Designed specifically for Cat landfill compactors to optimize compaction, five wheel and tip configurations are available for the new 836. The lighter paddle tip design delivers high performance and traction with less fuel burn, while the plus tip traditional design promotes stability on side slopes. The combination tip wheel incorporates both the paddle and plus tips to provide side slope stability. The chopper tip design is made for compacting wet or soft waste material.
