D7E Track-Type Tractor Engine Engine Model Net Power – SAE J1349 Drive Train Type Cat® C9.
D7E Features Electric Drive Power Train The revolutionary electric drive system delivers excellent dozing efficiency and performance while consuming considerably less fuel and fewer parts to reduce lifetime owning and operating costs. Operator Station Center post cab design offers more space, improved all-around visibility and reduced noise levels. ACERT™ Engine Technology Cat C9.
Power Train First-of-its-kind Electric Drive delivers power and efficiency. The electric generator, power inverter and propulsion module in the electric drive system replace traditional mechanical components such as a torque converter and transmission. The Cat® C9.3 engine with ACERT™ Technology turns a powerful electric generator that efficiently converts mechanical energy into AC electrical current.
Engine ACERT™ Technology. The D7E electric drive train is powered by a 235 hp Cat C9.3 engine with ACERT™ Technology. The engine utilizes a proven common rail fuel system for improved efficiency and fuel economy. Featuring the latest in Cat emissions reduction technologies, this engine meets U.S. EPA Tier 3, EU Stage IIIa and Japan MLIT Step 3 emissions regulations.
Operator Station Unprecedented all-around visibility and comfort. The all new D7E cab is designed to maximize operator efficiency. From the operator’s seat, the single center post aligns perfectly with the air intake, exhaust and lift cylinder, greatly enhancing forward visibility. The angled door provides more side glass area, improving sightlines to the blade and all around the job site. That helps operators work more confidently and productively all shift long and enhances job site safety.
Undercarriage Durable versatility. The D7E features an advanced low drive undercarriage design for greater machine versatility in a wider range of applications. Improved visibility, especially to the sides, is only one of the several benefits of this highly efficient undercarriage system. D10-size sprocket bearings give the D7E the added durability for a wide range of applications. Shock loads are directed through the roller frame to reduce wear and tear on the machine – and on the operator.
Technology Solutions Systems to achieve even greater productivity. AccuGrade™ System for Track-Type Tractors Caterpillar is helping customers revolutionize the way they move material with new technology solutions for earthmoving machines – solutions that provide greater accuracy, higher productivity, lower operating costs and more profitability. The AccuGrade System is designed and integrated into the machine and hydraulic systems to create an automated blade control.
Work Tools Designed for performance and versatility. Dozer Blades The D7E features a robust, single lift cylinder design. The single cylinder delivers the same power as a dual-cylinder system, but with fewer than half the components. Blade stability is excellent, supported by L-shaped push arms. Dozer blade capacity is the same as previous models, although the D7E blade enhances durability with thicker plating.
Serviceability Increase uptime by reducing service time. The D7E redefines serviceability. With easy access to service points and increased servicing intervals, the D7E can significantly reduce total owning and operating costs. • Service points are grouped on the left side of the machine for quick and easy routine maintenance. • A tilt cab allows easy access to modular major components, such as generator, propulsion module, power electronics and hydraulics.
