ZM330H/G Casing Oscillator

ZM330H/G Casing Oscillator

ZOOMLION offers ZM330H/G casing oscillator to tackle the challenges faced during large-diameter casing drilling as ground resistance and extraction loads rise. The foundation machinery has the maximum rotary torque of 19,900 kN·m and an extraction force of 10,860 kN that provides the power needed to rotate and retrieve heavy steel casings in difficult ground conditions. With a drilling diameter range of 2,200–3,300 mm, this heavy-duty full casing drilling rig is equipped for ultra-large-diameter, heavy-load pile foundation construction. Its high-torque, high-extraction-force capabilities make it relevant to demanding deep foundation and heavy-load piling projects.

  • Drilling diameter: Ø2200-Ø3300 mm
  • Rotary torque: 19900 kN•m
  • Extraction force: 10860 kN
