D8T WH (Tier 4 Interim/Stage IIIB)^Non-Current

The D8T cab is designed and equipped for operator productivity, safety and comfort. An isolation-mounted cab reduces noise and vibration. Large windows, tapered hood and notched fuel tank offer excellent all-around visibility. Updated dash and instrumentation streamline the display in a format that is common across the Cat tractor line. An air-ride suspension seat is standard, with a heated/ventilated seat as an option. Heating and air conditioning controls are conveniently located and well placed air vents add to operator comfort. Carbon filters are available for the cab air filters to help reduce odor.

Steering and Dozer Controls

Responsive electro-hydraulic differential steering controls direction and degree of turns, forward-reverse shifting, and gear selection in a single control handle. Ergonomically designed dozer and rear implement controls offer ease of operation, precise control and enhanced operator comfort.

Auto-Shift/Auto-Kickdown

Operators can pre-select a forward and reverse speed setting for easy, efficient directional changes. Auto-shift settings include first forward to second reverse and second forward to second reverse. Auto-kickdown allows the transmission to automatically downshift when significant load increases are detected.

In-Cab Safety Features

The Operator Not Present monitoring system senses when an operator has left the seat. When the transmission is in neutral, and at zero ground speed, the Operator Not Present monitoring system sets the park brake and disables the implements to prevent unintentional machine/implement movement during ingress or egress. When activated, the Implement/Work Tool Lock-Out Switch prevents inadvertent operation of hydraulic work tool attachments. An in-cab monitoring system provides electronic Fluid Level Verification at startup for the coolant, powertrain and engine oil systems. This reduces the need to climb on the machine to check fluid levels prior to operation.

The D8T features a Cat C15 ACERT™ engine and a Cat Clean Emissions Module to deliver the performance and efficiency that customers demand, while meeting U.S. EPA Tier 4 Interim/EU Stage IIIB emission standards.

Cat NOx Reduction System

The Cat NOx Reduction System captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.

Aftertreatment Technologies

A Diesel Oxidation Catalyst (DOC) uses a chemical process to eliminate regulated emissions present in the exhaust system. The Diesel Particulate Filter (DPF) traps particulate matter that is carried into the exhaust stream. System components are contained in the Cat Clean Emissions Module (CEM) to protect components, minimize the aftertreatment footprint and simplify maintenance. In Waste Handlers, the Clean Emissions Module is insulated for protection in high debris applications.

Cat Regeneration System

The Cat Regeneration System is designed to work transparently, without any interaction needed from the operator. Under many operating conditions, engine exhaust is hot enough to oxidize soot through passive regeneration. If supplemental regeneration is needed, the Cat Regeneration System elevates exhaust gas temperatures to remove soot in the Diesel Particulate Filter (DPF). This process happens automatically, but the operator can initiate the cycle when convenient or interrupt regeneration as needed. A soot level monitor and regeneration indicator lights are integrated into the dash display.

Delayed Engine Shutdown

Delayed Engine Shutdown feature is available to allow the machine to cool immediately after a heavy work load or regeneration cycle.

Engine Idle Shutdown Timer

An optional Engine Idle Shutdown Timer will sound a warning and shut down the engine after the machine has been idling for a pre-set period of time.

The power shift transmission and differential steering work with the C15 ACERT engine to deliver the outstanding power, productive performance and reliability expected from Cat Track-Type Tractors. Differential steering maintains full power to both tracks to provide best-in-class turning with a loaded blade. When one track speeds up, the other slows down an equal amount. Maneuverability - especially with large blade loads - is improved, as well as cycle times in some applications. Greater load capacity, power and speed control are possible in soft underfoot conditions on steep slopes.

Enhanced Auto Shift

The new Enhanced Auto Shift feature uses the simple “shift up, idle back” principle during forward and reverse travel to save fuel and improve overall dozing cycle fuel efficiency. The feature also simplifies machine operation for added operator comfort.

The D8T Waste Handler offers outstanding cooling performance and serviceability. The engine radiator, Air To Air After Cooler (ATAAC), and hydraulic oil cooler are packaged in a single plane. Aluminum bar plate construction provides durability and allows for higher heat transfer and superior corrosion resistance. The standard cores feature six fins per inch to allow debris to pass through and reduce plugging concerns. In cooler conditions, a hydraulically driven demand fan reduces speed to conserve power, save fuel and decrease sound levels. An automatic reversing fan changes the fan rotation while the machine is backing up or stationary. This feature includes access slots in the side of the radiator guard for cleaning access. ROPS-mounted air conditioning removes the condenser unit from under the hood. This helps reduce heat load, improves cleaning access and increases ambient capability.
