Multiple Drive Systems

Multiple Drive Systems

Three different drive systems, all designed with the right amount of speed and torque for working in a broad range of soil types.

  • A23 feature a variable speed, bi-directional, gerotor style hydraulic motor that generates optimal bit speed and output torque for light to moderate duty work.
  • A41 features a variable speed, bi-directional, single reduction planetary drive gerotor style hydraulic motor mounted to a planetary gear box for optimal bit speed and output torque for moderate to heavy-duty applications.
  • A68 features variable speed, bi-directional, double reduction planetary drive hydraulic gear motor mounted to a planetary gear box for optimal bit speed and output torque for moderate to heavy-duty, high performance drilling requirements.
