Overview

Do More with Less

Purpose-built for landfill operation, the Cat 826 delivers a level of reliability, performance, safety, operator comfort, serviceability, and efficiency that can only come from 45-plus years as an industry leader. Field-proven protection and integrated technologies provide peak availability and optimized landfill performance.

Benefits

Improved Maintenance

Make regular maintenance more convenient with accessible controls located inside the cab

Additional Safety

Grouped, ground level engine and machine controls allow for safe and easy daily maintenance

Enhanced Operator Comfort

Comfortable cab and low effort controls with reduced vibration levels help operators work more productively throughout the day

Features At A Glance

Flip-up armrest for easy ingress/egress.
Keep your operators informed about machine conditions and operation with Vital Information Management System (VIMS™) 3G machine monitoring system.
Enhanced visibility with standard rearview camera.
Preferred temperature settings maintained with automatic climate control.
Cat Premium Plus seat with standard features, including leather finish, forced air heating and cooling, two-way thigh adjustment, power lumbar and back bolster adjustment, and dynamic end dampening to provide total comfort throughout the workday.
Low spectator sound levels and optional low sound packages.

Easy access in a controlled environment; electronics bay is located inside the cab.
Focused on safety with ground level or platform access to most major components.
Ground level: engine shutdown switch, lockable battery disconnect, and auxiliary start.
Quick visual inspection and minimized fluid contamination with sight gauges for coolant, transmission, and hydraulic oil.
Electronic air inlet restriction indicator.
Designed for ease of service and inspection.
– Hydraulic oil cooler, fuel cooler, and roof-mounted condenser
– Centralized grease points
Operators and technicians can resolve any problems before failure using VIMS.
Guarding around the axles mitigates risk of damaged components.

Improved performance, long life, low emissions.
High productivity and fuel efficient.
Two engine options available that meet U.S. EPA Tier 4 Final and EU Stage V emission standards or emitting equivalent to U.S. EPA Tier 3 and EU Stage IIIA.
For the Tier 4 Final, EU Stage V option, the Cat Clean Emissions Module contains a diesel oxidation catalyst, diesel particulate filter, and Cat Regeneration System, utilizing selective catalytic reduction (SCR) technology.
Regeneration is completely automatic and does not interrupt the machine’s work cycle.
Experience maximum responsiveness and control with Steering and Transmission Integrated Control (STIC™) system.
Conserve more fuel with the automatic engine and electrical system shutdown.
Achieve greater momentum on grades and fuel savings by carrying that momentum through the shift points advanced productivity electronic control system (APECS) transmission controls.
Operators experience less fatigue with throttle lock to maintain engine speed.
Equipped with Cat torque converter with lock-up clutch which eliminates torque converter (TC) losses while lowering system heat and transfers more power to the ground.
Torque converter with lock-up clutch eliminates torque converter losses while lowering system heat. Improves travel speeds and increases fuel efficiency.
Lock-up torque converter transfers more power to the ground and optimizes fuel efficiency in all applications.

Compact technology combines advanced compaction measurement, in-cab guidance, and reporting capabilities to help you consistently meet compaction targets fast, uniformly, and in fewer passes – saving on fuel and the cost of unnecessary rework.
Link technology (standard) provides access to machine location, hours, fuel consumption, idle time, events, and diagnostic codes through the online VisionLink® interface.
Improved productivity with optional Cat Compact with Elevation Mapping.

Working in the toughest application, the purpose-built 826 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 Powertrain Guards – Hydraulically actuated guards help prevent trash buildup and shield components.
Front Frame Guards – Front frame guards prevent trash buildup 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 assists 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 buildup.
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.

Designed specifically to complement Cat machines.
Improves machine performance through longer wear life and maintaining traction.
Four wheel and tip configurations are available to meet your particular application:

Paddle Tip – High performance and less fuel burn with more traction and less weight.
Plus Tip – Traditional design for increased side slope stability.
Combination Tip – Both paddle and plus tips provide the best compromise of performance and fuel economy with side slope stability.
Diamond Tip – Longest life tip on the market with reputation of reliability that is world class in the waste tip industry.
