Komatsu D155PX-8 Crawler Dozer: CLASS-LEADING FLOTATION AND STABILITY

Jan 4, 2021, 13:16 PM by Jeff Richards
If you need a low-ground-pressure dozer for gas and pipeline work, you can’t do better than the new Komatsu D155PX-8. It has the lowest ground pressure in its class at just 7.7 psi.
 
The D155PX-8 LGP provides improved performance, flotation and stability. The new eight roller undercarriage evenly distributes the machine’s weight while providing greater traction and balance. It has 72% more ground contact area than a standard dozer, thanks to a track gauge that’s 12% wider and 9% longer than standard. The result is improved flotation in soft ground and better stability on slopes.
 
“The D155PX-8 is excellent for applications that require lower ground pressure and can be especially useful for energy and pipeline work,” said Chuck Murawski, Product Manager, Komatsu America. “When equipped with 38-inch extreme service shoes, angle blade, and towing winch, the D155PX-8 has a higher operating weight than competitors. That weight results in increased useable drawbar pull with a powerful towing winch.”
 
Despite the heavier weight, the D155PX’s ground pressure is 47% lower than a standard dozer.
 
For added versatility, the dozer is available with two blade options: an angle blade or a large capacity semi-U blade. The machine can use either a 12.9-cubic-yard bushed semi-U dual-tilt blade or a pitch semi-U blade. Both options move a lot of material, and the wider cutting edge reduces the number of passes needed while grading.
 
Rear attachments available include a hydraulic winch, long drawbar, and a counterweight with rigid drawbar.
 
The 354-hp dozer is covered by Komatsu’s factory scheduled maintenance program, Komatsu Care, for the first three years or 2,000 hours, whether you buy, rent, or lease the machine.
