2025 Komatsu Dozers D155CX-8 (K170)

Designed with pipelayers in mind. Built with purpose.

Developed and designed in conjunction with pipeline companies, the D155CX-8 has a 170,000-pound lift capacity and traditional oval track design to deliver the stability and performance required on large pipeline jobs. The draw works package and boom options have been specifically designed for handling up to 36-inch steel pipe, making it ideal for gas and oil projects.

Features may include:

Longer track on ground
  • Extended track roller frames and wider track gauge over previous models provide a solid foundation for pipe lifting. Large 9-inch track pitch undercarriage is built for pipelayer applications.
Purpose-built structures
  • Exceptional structural strength with a new front bumper and integrated towing pin designed to accept a standard winch rope terminator. An extended main frame with a non-oscillating hard bar has all drawworks mounts factory integrated.
Easy machine access
  • Easily access your machine with integrated left/right front steps, left access ladder and left/right rear walkways.
Transport storage bracket
  • Integrated load block transport storage bracket makes disassembly and assembly easier for shipping.
Integrated ROPS cab
  • Standard enclosed ROPS cab with auto climate control, large cab windows and skylight viewing area provides a comfortable operator environment in hot and cold climates.
