SF-55 CFA Rig

The SF-55 delivers the ideal combination of efficiency, smart working and compactness. The main design elements and the technological innovations come together in this new machine. Increased performance, simplicity and reliability are the results of this new step ahead.

New DMS 4.0, a multi-language adjustable 12” touch-screen to manage the drilling rig, monitor alarms, and set and store technology parameters in real time.

CFA Autorotary. This function increases the operator comfort reducing thefatigue and arm vibration during the drilling phase.

CFA Auto Drilling is the automated drilling system developed by Soilmec. DMS defines the correct mix of parameters and checks to ensure greater efficiency in terms of digging performance.

  • Allows the operator to detect the corkscrew effect
  • Allows the operator to detect excessive over-excavation & over-flighting
  • Optimises the level of auger filling
  • Optimises the drilling process
  • Allows the operator to become a controller of the automated functions set
  • Reduces stress and fatigue to the operator
