Abstract
A puller head and cable puller including the puller head are provided for pulling cable in an upward or a downward direction. The puller head includes a frame, a capstan mounted to the frame, and first and second retaining shaft apertures. The puller head is pivotally mounted to a boom of the cable puller through a pivot shaft. The capstan of the puller head is positioned rearward of the boom. The position of an upper most surface of the capstan relative to the boom is changed by pivoting the puller head between upward and downward pulling positions. The puller head is maintained in either the upward or downward pulling position through the use of a retaining shaft.
