D7E Waste Handler

Landfills are a crucial part in improving the cleanliness of our air, water, soil ... even the quality of our lives. Putting an innovative, conservation-minded track-type tractor to work on the landfill just makes sense. With its unique diesel-electric drive technology, it puts out fewer emissions and uses less fuel than conventional tractors. Like all Cat track-type tractors working in landfill applications, the D7E is a heavy-duty machine with waste handling guarding to safeguard uptime and support your business. It’s a powerful and highly maneuverable machine for dozing and compacting waste, and at the end of the day, will seamlessly convert to doing the fine grading required to place just the right depth of cover material.

Power Train



Heavyduty performance and fuel economy from dieselelectric drive.



The D7E features an electric generator, power inverter and propulsion module in place of the traditional mechanical torque converter and transmission. The result is a power train that uses 1030 less fuel depending on application while providing new levels of maneuverability and efficiency when delivering power to the ground. Turning the generator is the 235 hp175 kW Cat C9.3 turbocharged diesel engine. The Cat C9.3 comes from a rugged and dependable line of engines with the advantage of strong parts commonality across the Caterpillar product line. The engine runs in a very tight speed range of 1,500 and 1,800 rpm. Cats ACERT Technology governs the common rail fuel system for emissions control and precise loaddriven fuel mapping. For the D7E, the engines primary job is turning a generator to produce electricity as a result, a lower power rating can be accommodated. The D7Es C9.3 engine wont experience the drastic load and temperature changes, wear or fuel use of conventional dozer power plants. The D7E converts mechanical energy into AC current. The AC current is routed through highquality armored cables and militarygrade connectors to a propulsion module. The propulsion module delivers precisely modulated torque via axles to the final drives. Consisting of stateoftheart AC electrical motors and connected in turn to the D7E updated differential steering system the propulsion module has no moving electrical contacts and few moving mechanical parts. The result is a system that more efficiently converts power to dozing and compacting waste while controlling your costs with limited wear, fewer moving parts and lower fuel consumption. Cooling is provided by an auto reversing fan that passes air over single plane cooling cores. The D7E WHA cooling module is designed to allow small waste particles to pass through rather than be trapped by narrowspaced cores. These cores are super efficient with their single plane design and easy to clean.



Safeguarding cooling performance are specially designed, perforated and corrugated engine compartment doors. The perforations prevent entry of large debris, while only allowing debris to pass that will fully pass through the cooling cores. The corrugation in the design slows air velocity through the doors by increasing the doors surface area, reducing the suction that attracts flyaway debris. This highly engineered cooling system provides more uptime and higher performance with less cleaning required than conventional systems.

Operator Station



Unprecedented visibility to the work area and levels of operator comfort.



The D7E has a new, industryleading spacious cab offering important visibility in congested landfill environments. Strong emphasis was put on ergonomics for operator efficiency and comfort. Loweffort controls are simple, intuitive and comfortable for long shifts. Wide glass doors provide unobstructed visibility to both sides of the dozer blade and the waste pile. An optional camera attachment can be mounted to the rear of the machine making it easier for the operator to see whats going on directly behind the equipment. This feature can make all the difference when working in close proximity to trucks and people unloading at the dump site.



Additional cab features promote comfort and productivity with ulli Adjustable seat, controls, wrist and arm rests lili A very low noise level of 76 dBa in the cablili A singleunit heating, ventilation and air conditioning system that is self contained and powered by electrical current.

Structures and Undercarriage



Heavyduty construction and guarding for waste handling applications.

Structures



The D7Es structures are purpose built of highquality steel and box section construction. When it comes to structures, Caterpillar goes to extremes 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 longlife structures built for loads associated with quick directional changes, extreme slopes and heavyduty pushing or pulling. On Cat waste handling machines, these structures are further protected from wrapping, impact and abrasion. Heavyduty axles and machine fenders are standard on waste handling units and are built to withstand the demolition debris and hard knocks of a waste pile.

Undercarriage



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 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. ulli Trapezoidal hole shoes with 24 inches609.6 mm of width lili Trapezoidal hole shoes for low ground pressure configurations are 36 inches 914.4 mm wide.liul

Waste Handling Guarding and Seals
