Built to Perform

  • Integrated powertrain with differential steering and updated hydraulic system work together to provide power and improved machine maneuverability for any pipelayer application.
  • Electro-hydraulics offer greater response and precise control to variable speed motors of the heavy duty winches for greater machine productivity.
  • Differential steering maintains full power to both tracks for best-in class turning even with a loaded boom, increasing maneuverability in tight locations.
  • Improved machine center of gravity for better slope capabilities.

Because Uptime Counts

  • Equipped with Product Link™ which enables remote monitoring, improving overall fleet management effectiveness.
  • Full left-side engine serviceability, including fill tube, dipstick, air cleaner, fuel filters, oil filter and coolant level check allows for quick and efficient routine service.
  • High speed oil change is standard and makes servicing even faster.
  • Hydraulic and powertrain filters and fuel tank drain are located at rear of machine and are conveniently serviceable from ground level.
  • Pressure taps are placed within hydraulic system to allow for quick monitoring.
  • Major components like the engine, transmission, and final drives are modular for quicker removal during service, saving cost and downtime.

Designed for Operators

  • Implement joystick places all pipelayer implement controls and functionality in one hand.
  • Low-effort, ergonomically designed and positioned control handleallows simultaneous, precise positioning of load line, boom, andextendible counterweight.
  • Dual brake pedal controls provide enhanced maneuverabilityand steering control.
  • Planetary differential steering contributes to superiormaneuverability in tight areas of operation as well as enhancedslope capability.

Work in Comfort

  • Quieter, pressurized cab with heated/ventilated seat option improves operator comfort and productivity.
  • Ergonomically designed seat is positioned for greater visibility to work area and convenient access to machine control lever, switches and pedals.

Built-In Safety Features

  • Load Monitor Indicator (LMI) ready from factory and can accept regional LMI systems.
  • Convenient steps, handles and guardrail provide safe access/egress.
  • Enlarged roof top window with retractable shade, additional mirrors, and angled door improves visibility to the trench, boom and blocks.
  • Standard operator presence detection system allows machine to idle when operator is not seated, but locks out power train to avoid unintentional movement.
  • Rear vision camera available to further enhance visibility around machine.
