| Komatsu introduces D39EX-22 and D39PX-22 crawler dozers Komatsu America Corp. introduces the D39EX-22 and D39PX-22 crawler dozers. Equipped with Komatsu's proven Hydrostatic Transmission (HST) these machines are designed for work in general construction, site preparation, home building, forestry and utility applications. Building on the success of the D51-22 Dozer Series, the D39EX-22 machines feature a super-slant nose coupled with a new cab forward design that moves the operator closer to the blade while improving machine balance, ride and stability. Outfitted with a fuel efficient 4.5 Liter, EPA Tier 3 emissions certified Komatsu SAA4D107E-1 engine, these new models push with a net horsepower of 105 HP at 2,400 RPM and range in operating weight from 20,834 to 21,804 pounds, depending on the machine version. Both standard (EX) and low ground pressure (PX) models are available to offer customers weight distribution and flotation options to best match their application. The D39-22 steering system provides smooth agile movement when dozing, even in gradual turns, permitting the operator to approach dozing objects accurately in corner grading and sidewall operations. The D39-22 dozers employ a large power angle tilt blade with a capacity of 2.89 yd3 to 3.01 yd3, which results in more material staying on the blade and making it a more productive machine. The new dozer is equipped with the latest Komtrax technology which sends machine operating information to a secure website utilizing wireless technology. Hour meter, location, cautions and maintenance alerts – to name a few of its features – are relayed to the web application for analysis. The Komtrax fleet monitoring system increases machine availability, reduces the risk of machine theft, allows for remote diagnosis by the distributor, and provides a wealth of other information to drive business efficiency and productivity. write your comments about the article :: © 2008 Construction News :: home page |
