About the EK270LS

The EK270LS is a full cable crowd drilling rig mounted on a Cat® 352. The long stroke of the rotary makes it ideal for:

  • Cased kelly bar drilling with segmented (European style) casing, specially for Secant walls.
  • Large Diameter CFA.
  • Displacement piles.
  • Large diameter single column Soil Mixing.
Base:
  • The new Cat® 352 Next Gen powered by a fuel efficient Tier 4 Final C13 ACERT engine.
  • Equipped with Cat® Vision Link that allows management to monitor machine operations and maintenance data online and wireless, providing information such as location, hours, fuel usage, idle time, event codes and maintenance schedule.
