Benefits & Features
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 drivetrain 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 emissions standards.
The D7E uses a three-part cooling system that includes a rugged, highly efficient aluminum bar plate radiator. A larger gap between fins reduces plugging, and the single-plane design allows for easier cleaning and service. In cooler conditions, a hydraulically driven demand fan reduces speed to conserve power and reduce fuel consumption. An automatic Reversing Fan can be set to change 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. This helps reduce heat load, improves cleaning access and increases ambient capability.
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 Tier 4 Interim/Stage IIIB emissions standards and beyond, 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.
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 and striker bars 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.
Structures
Heavy duty performance for waste applications »Learn More
D7E waste handlers come with two undercarriage options, low ground pressure (LGP) or standard gauge. LGP machines provide flotation in soft underfoot conditions and stability on extreme slopes. The standard width option has greater compacting and shredding characteristics with the narrower shoe providing greater ground pressure.
Caterpillar offers a wide variety of shoes, but for landfill applications, recommends a trapezoidal hole shoe when working in trash. The design of this shoe allows it to shed waste that can otherwise cause accelerated internal track wear.
Trapezoidal hole shoes with 609.6 mm/24 inches of width
Trapezoidal hole shoes for low ground pressure configurations are 914.4 mm/36 inches wide.
