Free fall and slack rope monitoring for Kelly and grab drilling

Kelly winch: Fast lowering of the drilling tool can lead to the rope being unwound too quickly from the winches, should the winch no brake before the bottom of the borehole is reached. In order to prevent this, automatic slack rope detection can be activated.

Automatic slack rope detection

The control system ensures that the winches always hold the rope taut so that no unintended slacking of the rope on the winch can occur.

  • Free fall regulates the automatic re-positioning of the rope.
  • Automatic slack rope detection brakes the winches in good time.

Secure winch free fall

The control system brakes the winches in good time in order to prevent damage to the ropes.
