Komatsu America’s D155AX-8 crawler dozer has an operating weight of 89,300 pounds. Rated at 354 horsepower net, the D155AX-8 is powered by a Komatsu SAA6D140E-7 engine, which is EPA Tier 4 Final emissions certified.
Equipped with the KOMTRAX technology, data such as fuel levels, DEF levels, operating hours, location, cautions and maintenance alerts are relayed to the web application for analysis.
A new Operator Identification System reports key operating information for multiple operators and a new Auto Idle Shutdown function helps reduce idle time as well as operating costs.
The machine also is equipped with a 12.3-cubic-yard SIGMADOZER blade, which gives the machine a high-blade capacity. The SIGMADOZER improves dozing performance and is said to increase productivity up to 15 percent from a conventional Semi-U blade.
