Komatsu D155AX-8 LGP is a low ground pressure version of the 354-horsepower crawler dozer, and has 12 percent wider track gauge, 9 percent longer track on ground, and 47 percent lower ground pressure. Ground contact area is increased by 72 percent over the standard dozer, which has an operating weight of 89,300 pounds. Ground pressure is 7.7 psi, the company says.
Newly designed 8-roller undercarriage not only reduces ground pressure, but also increases traction and aids in the machine balance.
Two blades are available: semi-u blade or angle. The semi-u carries up to 12.9 cubic yards with dual tilt and pitch.
