The EK300LS is a full cable crowd drilling rig mounted on a CAT352. 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
  • Cased CFA with a double rotary for Secant walls.
  • Large diameter single column Soil Mixing.

The new Cat 352 is a purpose-built machine powered by a fuel-efficient U.S. EPA 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.

Caterpillar variable undercarriage VH5440/4900/900. Reinforced frame H style variable undercarriage. Length between wheels 5440mm, Transport width 3500mm, Operation width 4900mm, Shoe width 900mm.

Reinforced mast, with high resistance steel Weldox 900.
