The new Cat D7 dozer offers high drive undercarriage design, increased performance and the broadest choice of easy-to-use technology features to help customers get the most from the bulldozer. A fully automatic 4-speed transmission offers optimal fuel and dozing efficiency, plus ease of operation. At 197 kW (265 hp) and an operating weight of 29,776 kg (65,644 lbs), the new D7 dozer replaces the D7E.
Next Generation Value
The D7 moves up to 8 percent more material per hour than the D7E, with about 6 percent more weight and 12 percent more horsepower. Blade capacity is increased by 10 percent, and the elevated sprocket undercarriage delivers better ride and balance, as well as increased penetration force.
Like the D6 and D8T, the new D7 is driven by a fully automatic 4-speed transmission. The smooth-shifting transmission continuously adjusts for maximum efficiency and power to the ground without added operator input.
The completely redesigned cab, common with the D5 and D6/D6 XE, raises the standard in comfort and productivity. Operators will find more space, multiple seat and control adjustments for optimal comfort and an easy-to-use 254-mm (10-in) touchscreen operator interface. A standard High Definition rearview camera shows prominently in the main display.
Unprecedented Technology Choices
The D7 leads the industry with a variety of technology offerings that are easy to use and help customers get the most from an equipment investment. Slope Indicate is standard with the premium display package, showing machine main fall and cross-slope for easy reference.
ARO with Assist is a grade-ready option bundled with basic blade control and a new set of assist features that work in the background to help operators get more done in less time.
Customers can also add factory integrated Cat Grade with 3D. Advanced Inertial Measuring Units (IMU) provide greater speed and accuracy without position sensing cylinders. Small antennas are integrated into the cab roof for better protection and GPS receivers are mounted inside so they can be secured by locking the cab doors. An intuitive 254-mm (10-in) Grade operator interface works like a smart phone, making it easy for operators to pick up quickly. Android OS platform allows installation of custom apps for more versatility.
Remote Control Ready
The D7 is Remote Control Ready from the factory. Internal components are integrated into machine systems and an external connector allows dealer installation of a plug-and-play roof-mounted remote control unit. Cat Command for Dozing2 provides a remote control solution for enhanced safety and greater productivity and is offered as a Command Console for line-of-sight (LOS) remote control, or with a Command Station for LOS and non-line-of-sight (NLOS) remote control (available late 2021).
Connect to Greater Efficiency
Cat Link telematics technology helps take the complexity out of managing job sites – by gathering data generated by equipment, materials, and people – and serving it up in customizable formats.
Equipped for the Job
The D7 is available in Standard or Low Ground Pressure (LGP) configurations, with a variety of blade and track shoe choices to optimize the machine for the intended application.
The D7 can also be ordered with specialized guarding to take on the challenges of Waste/Landfill work and Forestry/Land Clearing. In addition to machine protection against impacts and airborne debris, these specialty dozers can be ordered with an impact-resistant cab, application-specific undercarriage and a specialty blade.
