Power and Performance
Note: Productivity, efficiency and owning/operating cost compared to previous D7R2 model.Electric Drive
A revolutionary Electric Drive system is designed to deliver quantum leaps in improved productivity and fuel efficiency. The D7E is up to 30 percent more fuel efficient than the D7R2. Better fuel economy plus greater productivity means you can move up to 35 percent more material per gallon/liter of fuel. And the D7E is more productive – moving 10 percent more material per hour. Fewer moving parts, less fuel and fluid and longer service intervals help reduce lifetime owning and operating costs.Advanced Electronics Control the Power
Electric generator, power inverter and propulsion module replace traditional components like a torque converter and transmission. A Cat C9.3 ACERT engine turns a powerful electric generator that efficiently converts mechanical energy into AC electrical current.Electric Propulsion Powers the Final Drives
Current from the generator flows through specially armored cables and military grade connectors to a solid-state power inverter. Advanced electronics send AC current to the propulsion module to control the motors and provides DC current for the accessory systems. The propulsion module, featuring state-of‑the-art AC electric motors, delivers well-modulated torque via axles to the final drives.Fully Sealed and Liquid Cooled
Drive train electrical components are fully sealed, so the D7E can safely operate in a wide range of dozing conditions. Liquid cooling ensures that the electric drive components deliver peak performance in extreme-temperature conditions.Powerful Maneuverability
Differential steering combines with electric drive to make the D7E so maneuverable that it can perform both uninterrupted power turns under load and “locked-track” pivot turns. A dedicated D8‑size steering pump delivers improved performance. The electric drive system is highly efficient at delivering engine power to the ground, and an infinitely variable speed control means smooth operations with no gears to shift.Cooling System
The D7E uses a three-part, aluminum bar core radiator for charged air, jacket water and the separate circuit. The single-plane design allows for easier cleaning and a 6-fins-per-inch design helps reduce plugging. A molded shroud ensures efficient air flow and the fan utilizes lightweight, durable blades for high efficiency and quiet operation. In cooler conditions, the hydraulic demand fan reduces speed to conserve power, save fuel and decrease sound levels. An optional reversing fan is available for high debris conditions.Traction Control
New standard feature reduces track slip for improved productivity and reduced undercarriage wear.Stable Blade Control
Standard Stable Blade Control complements operator input to automatically make instantaneous adjustments for smoother grading results with less effort.Economy Mode
When in use, Economy Mode automatically adjusts engine speed when machine is not under load to save you fuel. The operator's selected machine speed is maintained.Load Sensing Hydraulics
Field-proven system senses the load and continuously adjusts hydraulic power to maximize your work tool efficiency.
The D7E features a quiet, spacious cab. The center-post design gives you outstanding visibility all around the machine to help operators work more confidently and safely. Operators can also enjoy added comforts like manually adjustable armrests and a heated/ventilated seat option. The in-dash display monitors machine conditions in real time. Mount a grade control system display in the dash to put working information conveniently in front of the operator. A new in-cab main fall/cross slope display shows you real-time grade percentage during slope work. A single-unit cab-mounted heating, ventilation and air conditioning (HVAC) system is self contained and powered by the accessory power converter for more efficient cooling.Implement and Steering Controls
- Ergonomic controls are fully adjustable and designed for low-effort comfort. Switches and controls for various systems are located within easy reach of the operator.
- Speed recall feature allows operators to pre-set the desired forward and reverse travel speed, and then resume that speed simply by pressing a button.
- Implement Lock-Out prevents inadvertent operation of hydraulic attachments.
Emissions reduction technology on the D7E is designed to be transparent, with no action required from the operator. Regeneration runs automatically in the background while you work.Aftertreatment Technologies
Caterpillar designed earlier models with Tier 4 Final/Stage IV/Japan 2014 (Tier 4 Final) standards in mind. To meet the additional 80 percent reduction in NOx emissions, Caterpillar engineers added Selective Catalytic Reduction (SCR) to the already proven aftertreatment solution.Diesel Exhaust Fluid
Selective Catalytic Reduction utilizes Diesel Exhaust Fluid (DEF), which can be conveniently refilled when you refuel. A gauge on the dash shows your fluid level. The D7E offers excellent fluid efficiency. Across a variety of applications, the D7E typically has used DEF at a rate of 2-2.5 percent of fuel consumption. When the machine is turned off, a pump will automatically purge the DEF lines to help prevent freezing. A symbol on the dash and a light/symbol on the Ground Level Service Center indicate when the purge is complete and that it is safe to turn off the electrical disconnect. If the engine/aftertreatment temperatures are high, a Delayed Engine Shutdown will activate automatically to cool the machine and then purge the lines. For complete aftertreatment information, please refer to your machine's Operation and Maintenance Manual.
