Pulling eyes are provided with integrated wiring systems suitable for installing conductors or cables. The pulling eyes may include body portions that define interior cavities that are sized to snugly engage outside portions of the conductors or cables. The body portions are sized to be deformably crimped onto the outside portions of the conductors or cables. The pulling eyes may also include head portions joined to the body portions, with the head portions defining apertures for receiving a strength member for installing the conductors or cables. These apertures place the interior cavities in communication with the exteriors of the pulling eyes.

Cable pullers are provided. A cable puller includes a frame, and a boom assembly rotatably connected to the frame. The boom assembly includes a drive assembly, a first arm extending in a first direction from the drive assembly, a second arm extending in a second opposite direction from the drive assembly, and a third arm rotatably connected to the second arm. Rotation of the boom assembly relative to the frame causes rotation of the third arm relative to the second arm to a position wherein a longitudinal axis of the third arm is parallel with a longitudinal axis of the second arm.

A coupling device for coupling an electrical wire to a pull line includes a main body, a connector, a blade and a fixating element. The main body has a longitudinal direction. The connector is for connecting the main body to the pull line. The blade is coupled to the main body. The main body forms a space for receiving the electrical wire. The blade is configured to create a cut in the electrical wire. The fixating element is configured to fixate the blade in the cut. The fixating element is moveable relative to the main body. The main body includes an opening for receiving the fixating element. The opening is at an offset from the blade along the longitudinal direction.

A threading accessory comprising a belt and two rotatable wheels configured to revolve the belt which has a circumferential groove formed in an outer face thereof and configured to receive and hold a portion of a thread therein. One or more press-wheels are used to engage a portion of the belt passing between the rotating wheels and elastically deform the belt portion to thereby at least partially wrap it about and latch the thread portion inside in the circumferential groove for propulsion by the belt.

A cable grip includes a pulling arm/force member having an in-line linkage that minimizes moments on the grip when a pulling force is applied.

A cable puller and associated methods are shown. Useful example methods include pipe bursting using cable pullers as shown. Cable pullers and methods shown provide a mechanical advantage that increases an amount of cable pulled in one cycle. Selected examples are shown that include a pulley located on a distal end of a moving portion of an extending and contracting beam. The pulley and the mechanical advantage it supplies helps to improve the efficiency of the cable puller and reduce manufacturing cost of the cable puller.

An articulating, rotating pipe bursting head device is provided. More particularly, the improved pipe bursting head device disclosed herein comprises a coupling means at the back or posterior end of the bursting pipe head device which connects the bursting pipe head device to the replacement or product pipe, typically through a universal duct puller attached to the front or anterior end of the product pipe. In one preferred embodiment, the coupling means allows for articulation of the replacement pipe relative to the bursting pipe head device. In another preferred embodiment, the articulating coupling means allows for articulation from 0° through 90°. In another embodiment, the coupling means allows for rotation of the replacement pipe relative to the pipe bursting head device. In another embodiment this rotating coupling means allows for 360° rotation. Thus, the present disclosure describes an articulating, rotating bursting pipe head device and method of use.

A pull-in head assembly (8) for releasably connecting a pulling arrangement (112) to an elongate flexible structure (4, 6). The pull-in head assembly (8) comprises a body (30) which defines a pulling axis X of the pull-in head and a retaining member (32) which is configured to secure the pull-in head assembly (8) to an elongate flexible structure (4, 6) such that a pulling force exerted on the body (30) along the pulling axis X is transferred to the elongate flexible structure (4, 6). The pull-in head assembly (8) is configured such that, in use, the body (30) and the elongate flexible structure (4, 6) are rotatable with respect to each other about the pulling axis X.
