Komatsu’s D155AX-8 LGP Dozer
Komatsu’s new 354-hp D155AX-8 LGP (low ground pressure) dozer features a wide gauge and long track undercarriage for improved floatation and stability in all pipeline applications.
The D155AX-8 LGP operating weight is 100,000 lbs (45360 kg) when equipped with standard 38-in. extreme service shoes, angle blade and towing winch. This operating weight is significantly higher than competitors and increases useable drawbar pull. Its powerful towing winch with standard high-flow rear hydraulics has a bare drum maximum line pull rating of 150,000 lbs (68039 kg) and a full drum maximum line speed 166 ft per minute.
Despite its heavy weight, the D155AX-8 LGP has low ground pressure of 8.3 psi (57 KPa) and excellent stability due to its long track on ground 141 in. (3580 mm) and wide track gauge 94.5 in. (2,400 mm). The large capacity angle blade of 9.6-cu yds (7.3 m3) maximizes productivity and its 19-ft wide cutting edge can be used to finish grade a large area quickly. The D155AX-8 LGP, whether rented, leased or purchased, is covered by the Komatsu CARE program for the first three years or 2,000 hours.
