Abstract
A puller device for pulling a wire or rope through a conduit includes first and second motor-driven capstans about which a wire or rope can be wound for wire or rope-pulling purposes and an elongated arm arrangement having an end which is positionable adjacent the conduit through which the wire or rope is to be pulled. The first elongated arm member is connected to the second arm member for movement about a pivot axis, and there are provided a plurality of rollers adjacent the pivot axis having surfaces along which the wire or rope bears against so that forces which are exerted adjacent the pivot axis by the wire or rope are distributed between the rollers. In addition, a conduit-engaging assembly mounted upon the elongated arm arrangement holds the conduit in a fixed positional relationship with respect to the elongated arm arrangement during a wire or rope-pulling operation.
