March 14, 2020

The Komatsu D155CX-8 pipelayer has a 170,000-pound rated lift capacity and an oval track undercarriage designed to balance front/rear and left/right weight distribution. With long 12 feet 10 inches of track on ground, the D155CX-8 improves stability for pipeline work, says Komatsu, especially when working on adverse grades.

The Komatsu pipelayer has a standard 24-foot boom or optional 28-foot boom. Long and wide oval track undercarriage places the final drives and other heavy components lower to the ground for improved stability.

The Komatsu Tier 4-F SAA6D140E-7 engine delivering 360 horsepower. It has a heavy-duty selective catalytic reduction system and a diesel exhaust fluid system. Paired with the diesel particulate filter, the systems reduce particulate matter and NOx while providing automatic regeneration. Auto idle shutdown helps reduce excessive idle time.

Featuring a ROPS cab with automatic climate control, large cab windows, a skylight viewing area, and both front and rear view cameras. A right-side, counterweight-mounted camera is also standard. An optional load-moment indicator is also available. Simple breakdown also makes the D155CX-8 easy to transport, says the company.

The D155CX-8 also features Komatsu’s 3-speed Torqflow transmission, consisting of a water-cooled, 3-element, 1 phase, torque converter, and planetary gear, multiple-disc clutch transmission which is hydraulically actuated and force lubricated for optimum heat dissipation.

The machine’s diagnostic system monitors operation and vitals to identify issues and assist with troubleshooting. Complete operator control includes a palm command control system, boom/hook/counterweight functions on one joystick lever, 3-speed manual shift transmission, a forward/reverse shift pattern preset function, and electric-hydraulic controlled winches.

The D155CX-8 also features Palm Command Control System (PCCS) lever controls for all directional movements. Wet, multiple-disc, pedal-controlled service brakes are spring-actuated and hydraulically released. A gear shift lock lever also applies parking brakes.

A 7-inch color monitor provides multiple choice pull-down menus and onboard diagnostics, without requiring a laptop. The machine is accessible from all four corners, and a battery disconnect switch can be locked out for safety. Tie-offs for technician restraint harnesses are also included.
