New Cat® 826K Landfill Compactor Sets The Standard

Tuesday, August 12 th, 2014

The Cat® 826 Landfill Compactor has set the design standard for this demanding application since 1978, and with the introduction of the K Series model, that design is further advanced in terms of operator comfort and safety, ease of operation, durability, reliability, low-cost operation, and productivity.

Because the landfill compactor works in the harshest of applications, Caterpillar has designed the machine with purpose-built structures that deliver long-term durability. Two Cat C15 ACERT™ engine options are available, meeting EU Stage IV emission standards. It delivers 405 net horsepower (302 kW) to the 826K’s drive train, which uses a 2F/2R planetary power-shift transmission, lock-up torque converter, and heavy-duty planetary axles that can accommodate three new wheel-and- tip configurations. With an operating weight of 90,207 pounds (40 917 kg), coupled with massive structures that remain solid through a number of rebuilds, the 826K is built for rugged durability.

For fuel-saving performance, the 826K features an Eco Mode, which, when selected by the operator, limits engine speed and allows the machine to function in an auto-shift mode when maximum torque is not required. For operator convenience, the left pedal serves as a brake, transmission neutralizer, and engine decelerator, which the operator can use to temporarily override the engine speed set with the throttle lock for safely manoeuvring around obstacles. And for optimum responsiveness and control, the 826K’s STIC™ system allows single-lever steering and transmission control.

Cat 826 2Operator comfort and convenience is further accommodated in the design of the 826K with easier entrance and exit from the cab with lighted, shallow-angle stairways and a STIC armrest that folds away. The Cat Comfort Series air-suspension seat features extra thick cushions and moves the attached electro-hydraulic STIC-control pod and implement-control pod when adjusted. The cab, isolation-mounted to the frame, is pressurized with filtered air, and the selected temperature is maintained automatically. The control panel uses large, back-lit switches with LED indicators, and a simple two-position rocker switch controls the parking brake.

The 826K delivers consistent, smooth shifting via integrated electronic controls that use the Caterpillar Single Clutch Speed Shifting system. The metallurgy and heat-treating incorporated into the transmission’s gearing ensure consistent performance and long-term durability. The lock-up torque converter used in the 826K has several benefits, including more efficient transmission of power, lower system heat, increased travel speed, and fuel efficiency. Further fuel savings are achieved with the C15’s Engine Idle Shutdown system, and engine durability is enhanced with delayed engine shutdown.
