User manual CATERPILLAR D7E WH BROCHURE

[. . . ] 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 Heavy-duty performance and fuel economy from diesel-electric 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 10-30% 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 hp/175 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. [. . . ] Speed recall allows the operator to set an appropriate forward and reverse speed and resuming it with the push of a button Strobe light for the cab roof ­ active when the battery disconnect is turned on for a quick indication of machine disconnect status · · · 4 Structures and Undercarriage Structures The D7E's structures are purpose built of high-quality 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 long-life structures built for loads associated with quick directional changes, extreme slopes and heavy-duty pushing or pulling. On Cat waste handling machines, these structures are further protected from wrapping, impact and abrasion. Heavy-duty 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. Heavy-duty construction and guarding for waste handling applications. 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. · · Trapezoidal hole shoes with 24 inches/609. 6 mm of width Trapezoidal hole shoes for low ground pressure configurations are 36 inches /914. 4 mm wide. 5 Waste Handling Guarding and Seals A commitment of long life and quality for our waste handling customers. 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 clean out. Radiator Grill Screen ­ tight mesh to prevent debris from entering coolers during reversing fan cleaning cycle Perforated and corrugated engine compartment doors safeguard cooling performance 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 against impact loads Fuel tank guarding also protects the hydraulic tank and battery box against puncture and contamination Dozer blade hydraulic line protection with a ring design that protects lines while shedding debris. Track guide guards provide track alignment on slopes Clamshell and Kevlar seals ­ new final drive seal protection comprised of heavy-duty cast guards, stepped labyrinths and Kevlar seals to protect final drives and their dual cone seals Cat Turbine Precleaner with screen ­ delivers clean air and provides longer filter life Thermal Shield Arrangement ­ lowers skin temperature of exhaust components and provides cooling to the turbo that protects bearings after shutdown. Black hood and lift cylinder cut glare during night shifts Solid bar handholds hold their form and offer three points of contact on and off the machine Chassis Sealing ­ extensive rubber, foam, and steel sealing components prevent debris from entering the engine and transmission compartments · · · · · · · · · · · · · · 6 Optional Waste Handling Attachment Recommended Attachments for improved safety in landfill applications. Following are features that are optional but can improve machine performance, life or operator comfort in waste applications. · · · · · · · Trapezoidal hole shoe design allows debris to be extruded from the link box, reducing the risk of packing and chain stretching Front striker bars ­ deflects debris being carried up the front of the track when in reverse, reducing risk of cab damage Enhanced clean air module increases cab air pressure to keep dust out and provide additional air filtration, greatly increasing cab air filter life High intensity discharge lighting with additional lamps for optimum visibility under low light conditions Cab roof-mounted strobe light indicating the machine is operational Rear Vision Camera ­ allows the operator to see behind the machine from a cab-mounted display that is comfortable to use and promotes good visibility practices Cab door screens protect the lower half of the glass doors from demolition debris, while allowing good visibility to the blade 7 Work Tools Application specific designs for dependable performance. Caterpillar offers four landfill blades, ripper and winch options to meet site specific requirements. Semi Universal Landfill Blade with Wear Plate The semi universal blade is designed for high capacity loading, load retention and material penetration. For landfill applications, it carries a ½ inch wear plate on moldboard center sections and wings and an integrated 610 mm/24 inch trash rack. With the rack, this blade has a capacity of 14 cubic meters or 18. 4 cubic yards. Universal Landfill Blade with Wear Plate The universal blade is designed with wings on each side of the blade to carry large loads, longer distances. With its unique cutting edge design, this blade is best suited to stockpile work in lighter material which makes it an excellent landfill blade. For landfill applications, it carries a ½ inch wear plate on moldboard center sections and wings and an integrated 610 mm/24 inch trash rack. With the rack, this blade has a capacity of 16. 8 cubic meters or 22 cubic yards. Straight Landfill Blade with Wear Plate The straight blade is a smaller blade offering maneuverability and aggressive digging characteristics to the machine. Providing useable information to maximize landfill equipment uptime and reduce fleet owning and operating costs by monitoring machine health, service meter hours, idle time, fuel burn, utilization and much more. 9 Serviceability Increase uptime by reducing service time. The D7E redefines serviceability.
