Komatsu America introduces the D155AX-8 LGP dozer

D155AX-8

Komatsu America has launched its new 354 horsepower D155AX-8 LGP (low ground pressure) dozer.

The new machine incorporates the proven Komatsu technology used in the D155AX-8, enhanced with two blade options and more track on the ground.

With 12 per cent wider track gauge, 9 per cent longer track on ground and 47 per cent lower ground pressure than the standard model, the D155AX-8 LGP offers improved performance, floatation and stability.

D155AX-8 LGP’s undercarriage

Compared to the standard dozer model, the D155AX-8 LGP’s new 8-roller undercarriage provides greater traction and more balance, while significantly reducing ground pressure.

Equipped with either large capacity semi-u blade or an angle blade, the D155AX-8 LGP can move large amounts of material, while the wider cutting edge reduces the number of passes needed when grading.

“The D155AX-8 LGP is excellent for applications that require lower ground pressure and can be especially useful for energy and pipeline work,” said Chuck Murawski, product manager for Komatsu America.

“When equipped with (965 mm) extreme service shoes, angle blade and towing winch, the D155AX-8 LGP has a higher operating weight compared to competitors for increased useable drawbar pull with a powerful towing winch.”

For applications that don’t require an angle blade, higher capacity 9.86 cubic metre bushed semi-u dual tilt and pitch semi-u blades are available.

More weight, less pressure

Although the dozer features a heavier weight, the D155AX-8 LGP’s longer and wider track maintains a lowest-in-class ground pressure of only 7.7 psi.

The ground contact area is increased by 72 per cent 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. Komatsu’s ergonomically designed Palm Command Control System (PCCS) gives operators maximum control, offering a relaxed posture and superb fine control.

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