Overview

Since the introduction of the D7E dozer, customers worldwide have saved millions of liters/gallons of diesel fuel and reduced overall emissions.* The D7E features an innovative diesel-electric power train that helps you save money by getting more work done while using significantly less fuel. Electric drive gives you the power you need for dozing, along with the smooth operation and agile maneuverability suited to a wide variety of applications. The new D7E meets Tier 4 Final/Stage IV/Japan 2014 (Tier 4 Final) emission standards. *Compared to the D7R2.

Note (1)
All non road Tier 4 Interim and Final, Stage IIIB and IV, Japan 2014 (Tier 4 Final) and Korea Tier 4 diesel engines are required to use only Ultra Low Sulfur Diesel (ULSD) fuels containing 15 ppm EPA/10 ppm EU (mg/kg) sulfur or less. Biodiesel blends up to B20 (20% blend by volume) are acceptable when blended with 15 ppm (mg/kg) sulfur or less ULSD. B20 should meet ASTM D7467 specification (biodiesel blend stock should meet Cat biodiesel spec, ASTM D6751 or EN 14214). Cat DEO-ULS™ or oils that meet the Cat ECF-3, API CJ-4, and ACEA E9 specification are required. Consult your OMM for further machine specific fuel recommendations.
Note (2)
Diesel Exhaust Fluid (DEF) used in Cat Selective Catalytic Reduction (SCR) systems must meet the requirements outlined in the International Organization for Standardization (ISO) standard 22241.

Features

MOVE MORE WITH LESS FUEL

  • Up to 30% more fuel efficient than the D7R2.
  • Productive – moves 10% more material per hour.
  • Better fuel economy plus greater productivity means you can move upto 35% more material per gallon/liter of fuel.
  • Fewer moving parts, less fuel and fluid and longer service intervals help reduce lifetime owning and operating costs.

    Note: All comparisons to D7R2

OPERATOR COMFORT AND CONTROL

  • Spacious cab with center-post design gives you outstanding visibility all around the machine for increased confidence and safely.
  • Added comforts include manually adjustable armrests and a heated/ventilated seat option.
  • Add Grade Control display to put working information conveniently in front of the operator.
  • Heating, ventilation and air conditioning (HVAC) system is self contained.
  • Ergonomic implement and steering controls are fully adjustable and offer low-effort comfort.
  • Switches and controls for machine systems are located within easy reach.
  • Speed Recall allows operators to pre-set the desired forward and reverse travel speed, and then resume that speed with the press of a button.
  • Implement Lock-Out prevents inadvertent operation of hydraulic attachments.

TECHNOLOGY THAT GETS WORK DONE

  • Standard Stable Blade Control complements operator input to automatically make instantaneous adjustments for smoother grading results with less effort.
  • In-cab main fall/cross slope display shows you real-time grade percentage during slope work.
  • Traction Control reduces track slip for improved productivity, more fuel efficiency and reduced undercarriage wear.
  • When in use, Economy Mode automatically adjusts engine speed when machine is not under load to save you even more fuel.
  • Product Link™ collects machine data that can be viewed online through web and mobile applications.
  • Access information anytime, anywhere with VisionLink® – and use it to make informed decisions that boost productivity, lowercosts, simplify maintenance, and improve safety and security on your job site.
  • The Cat App helps you manage your assets – at any time – right from your smartphone. See fleet location and hours, get critical required maintenance alerts, and even request service from your local Cat dealer.

BUILT TO PERFORM

  • 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.
  • 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.
  • A robust, single lift cylinder design and L-shaped push arms give you an advantage over diagonal brace designs by bringing the blade closer to the machine. Provides better balance, stability, maneuverability and blade penetration.

LOWER MAINTENANCE COSTS

  • Easy access to service points, fewer moving parts and longer service intervals, add up to significantly lower owning and operating costs.
  • Tilt cab allows easy access to major modular components: generator, propulsion module, power electronics and hydraulics.
  • Heating, ventilation and air conditioning (HVAC) system is self contained for improved performance, increased service intervals and ease of serviceability.
  • Service points are grouped on the left side of the machine for quick and easy routine maintenance.
  • Ground-level sight gauges let you inspect fluid levels at a glance.
  • Modular final drives are easily accessed for maintenance.
  • Optional high-speed oil change attachment makes servicing even faster.
  • Shovel mounting bracket on the back of the machine means quick undercarriage cleanouts on the go.
  • Ground level service center on the left fender offers easy access to the battery disconnect, hour meter, remote engine shutdown and access light switches. It also houses an LED warning indicator showing that the power train and accessory systems are energized. When the systems are de‑energized and safe for maintenance, the indicator turns off.

BUILT-IN SAFETY FEATURES

  • Pull-down ladder provides convenient access for fueling and to the back of the machine.
  • Seat belt indicator registers a fault code through Product Link if the operator fails to buckle up, helping to improve your job site safety.
  • Center-post cab with angled doors offers excellent visibility to help operators work more safely.
  • Rear vision camera is available to enhance visibility behind the machine.
  • Operator Presence detection system allows the machine to idle when the operator is not seated, but locks out the power train and front implements to avoid unintentional movement.
  • Convenient steps and handles help you get on and off the tractor with greater ease. Access lighting can be turned on from a ground level switch.

WASTE HANDLING PERFORMANCE

  • Specialized guarding, striker bars and seals help protect the machine from impact and airborne debris.
  • Purpose-built heavy duty final drive guarding help prevent wire, cables, rope and debris from wrapping into the final drive seals.
  • Heavy duty sealed bottom guards protect the engine and power train system.
  • Reversing fan and single plane cooling cores with 6 fins per inch are ideal for high debris environments. Easy access clean out.
  • Insulated Clean Emissions Module for thermal protection.
  • Lights are mounted up and away from main debris area for protection, while still giving you plenty of light on the work area.
  • Specialized air handling features help deliver cleaner air to the machine and to the cab.
