Three models have been added to the line of intelligent Machine Control crawler dozers: D37i-23, D39i-23, and D51i-22. Units have fully automatic blade control for both rough and finish grading. Factory-installed cab-top GNSS antenna, enhanced inertial measurement unit, and stroke-sensing hydraulic cylinders replace machine control components typically mounted on the blade.
Operating weights for the D51i-22 range from 27,381 to 29,057 pounds, and it is powered by a Tier 3 SAA6D107E-1 engine providing 130 horsepower at 2,200 rpm. Operating weights for the D37i-23 and D39i-23 range from 18,872 to 21,848 pounds. Tier 4-Interim engines provide 89 and 105 horsepower at 2,200 rpm, respectively.
The dozers also feature the integration of the KOMTRAX telematics system and Topcon’s construction management system.
Komatsu says its WA470-8 wheel loader uses up to 6 percent less fuel than the Dash 7 version.
The PC210LC-11 excavator has a Tier 4-Final SAA6D107E-3 engine that provides 7 more horsepower, at 165, than its predecessor.
