Komatsu America unveils D155AX-8 LGP (low ground pressure) dozer

Komatsu America has launched its 354 horsepower D155AX-8 LGP (low ground pressure) dozer which it says is offers two blade options and more track on the ground.

The company claims the dozer comes with 12% wider track gauge, 9% longer track on the ground and 47% lower ground pressure than the standard model.

D155AX-8 LGP’s -roller undercarriage is expected to provide greater traction than the standard model while also reducing ground pressure.

The machine can be equipped with either a large capacity semi-u blade or an angle blade to move large amounts of material. The wider cutting edge reduces the number of passes needed when grading, the company adds.

For applications that do not require an angle blade, higher capacity 12.9 yd3 bushed semi-u dual tilt and pitch semi-u blades are available.

According to Komatsu, the D155AX-8 LGP’s longer and wider track maintains a ground pressure of 7.7 psi (53 KPa). The ground contact area is increased by 72% from the standard model for improved floatation in soft ground, and the long and wide undercarriage provides better stability on slopes and excellent machine balance. The eight fixed mounted track rollers per side distribute the machine weight.

The ROPS cab provides nearly unobstructed visibility to both sides of the machine and there are no external ROPS posts to block the operator’s view.

Optional rear attachments include a counterweight with rigid drawbar (3568 kg/7,860 lbs.), a hydraulic winch and long drawbar.
