BENEFITS & FEATURES
Engine and Power Train
Innovative Electric Drive


Engine and Power Train

The D7E uses an innovative Electric Drive system for improved productivity and efficiency. The D7E uses 10-30 percent less fuel than the previous D7 model - as well as fewer parts and fluids - to help reduce overall owning and operating costs. All electrical components are fully sealed to safely operate in a wide range of dozing conditions. Liquid cooling ensures that the electric drive components deliver peak performance in extreme temperature conditions. The D7E is highly maneuverable and infinitely variable speed control means there are no gears to shift. The efficient diesel-electric drive train allows the engine to operate in a tighter RPM range, 1,500-1,800 rpm, which helps extend engine life and improve fuel economy. A Cat C9.3 ACERT engine and Cat Clean Emissions Module aftertreatment meet U.S. EPA Tier 4 Interim/EU Stage IIIB/Japan MLIT Step 4 emission standards.

Cooling
Efficient and easy to service


Cooling

The highly efficient electric drive train places less heat demand on the cooling system. This helps improve engine and power train life and reduces your maintenance.
  • Three-part cooling system with rugged, highly efficient aluminum bar plate radiator.
  • Larger gap between fins reduces plugging.
  • Single-plane design for easier cleaning and service.
  • Hydraulically driven demand fan reduces speed in cooler conditions to conserve power and reduce your fuel consumption.
  • Automatic Reversing Fan changes air flow direction, efficiently removing debris from the cooling cores and engine enclosure without the operator leaving the cab.
  • Roof-mounted air conditioning removes the condenser unit from under the hood to help reduce heat load, improve cleaning access and increase ambient capability.

Emissions Technology
Reliable, integrated solutions


Emissions Technology

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
To meet U.S. EPA Tier 4 Interim/EU Stage IIIB/Japan MLIT Step 4 emission standards, Cat aftertreatment components have been designed to match application needs. System components include a Diesel Oxidation Catalyst (DOC), which uses a chemical process to convert regulated emissions in the exhaust system, and a Diesel Particulate Filter (DPF) that traps particulate matter that is carried into the exhaust stream. The DOC, DPF and Cat Regeneration System are contained in a Caterpillar designed Clean Emissions Module (CEM) that protects the components, minimizes the aftertreatment footprint and simplifies maintenance. For waste handling and other high debris applications that require thermal shields on exhaust components, an insulated CEM is available for the D7E.

Cat Regeneration System
The Cat Regeneration System is designed to work transparently, without any interaction needed from the operator. Under most 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 burn off soot in the Diesel Particulate Filter (DPF). This is a process that 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 D7E 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.

Structures
Heavy duty performance for waste applications


Structures

The D7E’s structures are purpose built of high-quality steel and box section construction. When it comes to structures, Caterpillar is thorough, with application specific, finite element analysis at initial design, followed by prototype shake table testing, and finally pilot machine testing prior to production. The results are long-life structures built for loads associated with quick directional changes, extreme slopes and heavy-duty pushing or pulling. In addition to the rugged structures found on standard Cat dozers, waste handling machines feature added guarding to help protect the machine from debris wrapping, impact and abrasion. The D7E Waste Handler is designed from the inside out to withstand demolition debris and the hard knocks of the waste pile.

Undercarriage
Equipped for the job


Undercarriage

D7E waste handlers are offered in two track shoe widths. The 660 mm (26 inch) shoe has greater compacting and shredding characteristics and higher ground pressure. The 914 mm (36 inch) shoe provides greater flotation in soft underfoot conditions. For landfill applications, Caterpillar recommends a trapezoidal hole shoe when working in trash. The shoe is specially designed to shed waste that can otherwise contribute to accelerated internal track wear.

Waste Handling Guarding and Seals
A commitment of long life and quality for our waste handling customers


Waste Handling Guarding and Seals

With a full line of waste handling equipment, Caterpillar has the experience and design know-how to keep machines running in waste. Cat Waste Handlers are designed with seals and guarding that are critical to the life of your investment and keeping the D7E productive in this application.
  • Radiator Grill - heavy-duty guard protects the radiator, angled to deflect debris and hinged for convenient cleanout. A tight mesh screen helps prevent debris from entering coolers and radiator.
  • Insulated Cat Clean Emissions Module
  • Rear striker bars - removes and prevents debris from traveling up the track, protecting the cab, fenders and fuel tank
  • Idler and pivot shaft seal guards - prevent damage caused by wrapping wire or waste contaminants
  • Chassis and bottom guarding protect against impact loads
  • Fuel tank guarding also protects the hydraulic tank and battery box against damage
  • Dozer blade hydraulic line protection with a rotating sleeve design that protects lines while shedding debris
  • Clamshell and Kevlar seals - final drive seal protection comprised of heavy-duty cast guards, stepped labyrinths and Kevlar seals to protect final drives and their Duo-Cone® seals
  • Precleaner with screen promotes longer air filter life
  • Thermal Shield Arrangement - lowers skin temperature of exhaust components and provides cooling to the turbo bearings
  • Black hood and lift cylinder cut glare
  • Chassis Sealing - extensive rubber, foam, and steel sealing components prevent debris from entering the engine and transmission compartments

Work Tools
Equipped for the job


Work Tools

Blade
This wide, straight blade easily handles heavy or bank materials. For landfill applications, it carries a ½ inch wear plate on the moldboard and an integrated 610 mm (24 in) trash rack. With the rack, this blade has a capacity of 12.3 m3 (16.1 yd3). Ask your Cat dealer about other blade options.

Ripper
Multi-shank rippers can make short work of loosening and preparing cover material. Cast-in ripper mounts allow a ripper to be mounted quickly and easily.

Winch
A hydraulic winch with positive load control, variable speed and dual braking can pull trucks, equipment or debris with a single lever control in the cab.

Optional Waste Handling Attachments
