Caterpillar launches new mastless CAT grade with 3D for motor graders at ConExpo-Con/AGG 2020 (pictured above)
The new Cat GRADE with 3D for motor graders allows contractors to realize the improved grading efficiency, accuracy and productivity of automated grading systems without the limitations associated with GPS masts. The new integrated mastless grade system can be installed and calibrated at the factory on new machine orders or as a field retrofit for existing models in customers’ fleets. Retrofit kits are available for pre- and post-2019 M Series models equipped with or without the Attachment Ready Option (ARO).
Previous GPS systems for motor graders required 6-ft-tall (1.8-m) masts mounted to the ends of the moldboard, exposing the components to potential damage and theft. The antennas/receivers were often removed and installed daily, limiting the machine’s time in the dirt, and the masts limited the blade’s range of motion. The masts also limited the types of applications for the motor grader.
With GNSS antenna/receivers mounted on the cab and front chassis of the motor grader, the new Cat GRADE with 3D system offers a factory installed solution that significantly reduces the potential for component damage and theft as well as eliminates the need for daily removal. Removing the masts and cables deliver maximum productivity and full range of motion for the moldboard.
The new Cat GRADE with 3D system delivers incredible accuracy and efficiency, while improving productivity. By offering automatic blade control, the system reduces manual operator inputs and allows operators to be more productive. E-Fence comes from the factory for Cat GRADE with 3D. When activated, E-Fence prevents the moldboard from contacting the tires and ladder and prevents the circle from potentially damaging to the link bar.
With the new Cat GRADE with 3D, no longer do contractors need to dedicate one machine to GPS. Cat motor graders equipped with the new mastless system can work on a broad range of applications, including bank slope, cutting passes, mixing materials, ditch building, clearing and back slope, and high slope.
Cat 140, 150 and 160 motor graders will be the first models equipped with the new mastless Cat GRADE with 3D. The system is installed on the Cat 150 motor grader at CONEXPO-CON/AGG 2020 in Caterpillar booth #F4455, located at the show’s new outdoor Festival Grounds. Production of the new GRADE system will begin in the second half of 2020.
New CAT 140 GC motor grader produces high performance at low cost per hour\
The new Cat® 140 GC motor grader is designed to combine high performance with low owning and operating costs. The 140 GC’s powerful Cat C7.1 engine, 6F/3R automatic power-shift transmission (which eliminates the inching pedal), and precisely designed hydraulic system ensure balanced performance in all operating situations. An ECO operating mode and demand-fan reduce fuel consumption, and extended maintenance intervals further reduce operating costs. Operators of all skill levels quickly achieve high production with the 140 GC, and options that include adjustable seats and efficient heating/cooling systems guarantee comfort.
With 45 years of refinement, the 140 GC’s conventional steering wheel and lever controls are familiar to operators and ensure positive control. The control console adjusts to the operator’s preference, and the powerful heating and cooling system option dehumidifies and pressurizes the cab, while circulating fresh air to seal out dust and keep windows clear. Seat upgrades include mechanical or air suspension; static seat is standard.
The 140 GC’s standard no-spin differential activates with no operator input to increase traction in poor ground conditions and to protect drive-train components from damage. The all-wheel-drive option provides added performance in rough terrain or poor underfoot conditions. Optimized machine balance ensures maximum drawbar power to the ground. Adding the 4.3 m (14 ft) moldboard option offers more road coverage. The optional Digital Blade Slope Meter takes the guesswork out of slope control and keeps the job site safer by eliminating manual grade checks. Cat Detect with Vision System (optional) uses a rearview camera to show a wide view behind the machine.
New High Drive Cat D7 Dozer delivers more performance and unmatched productivity-boosting technology
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.
