5K – 7K Helical Drive Head

PierTech’s Standard Helical Drive Heads were designed specifically for helical pier or pile installation.  Designed by real-world engineers who understand the demands of the foundation industry, these drive heads are designed to perform under the most strenuous environments.  Their design also allows them to run at the highest efficiency rates so that they will perform dependably for years.

Features

  • High efficiency hydraulic motor
  • Built-in pressure relief valve
  • ICV (Inertia Control Valve) prevents sudden decompression of oil, caused by pile kick-back
  • Designed for maximum strength
  • Ultra duty shaft
  • Case Drain is not required
  • 3 year gearbox warranty

More Torque Less Pressure

Two pressure series are available to suit your requirements:

  • Standard pressure series for machines with 3500 PSI (ADS range)
  • Low Pressure series, for machines with 3000 PSI (ALS range)
