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.
The D155AX-8 crawler dozer has an operating weight of 89,300 pounds and is powered by a 354-horsepower Komatsu SAA6D140E-7 diesel
Following the release of four intelligent Machine Control (iMC) crawler dozers, Komatsu has now introduced its first intelligent Machine Control excavator, the PC210LCi-10.
