Abstract
A cable puller adapter includes a rotatable gripping member which receives and guides a tailing portion of a pulling line coupled between a capstan of a cable puller and the gripping member, an adapter motor which applies torque to the gripping member, and a controller operatively coupled to the gripping member and configured to measure an amount of current drawn by or provided to the adapter motor, and configured to determine a rotational speed of the adapter motor or the gripping member. The controller adjusts a tailing force on a tailing portion of the pulling line by modulating an amount of current provided to the adapter motor, so as to maximize a velocity of the tailing portion of the pulling line as the gripping member rotates. A method of use is also provided.
