摘要： Method and apparatus for pulling electrical wire through a conduit of an electrical breaker box such as might be installed at a residential home or commercial building wherein the feed wire from a main electrical feed source would be delivered and tied into the applicable home or commercial building. The device has a generally upright standing shaft having a pivot point forming upper and lower shaft portions having a pair of pulleys mounted thereon so that the electrical wire can travel over the pulleys as it is pulled by the hands of the user. The lower shaft portion has a lower brace member thereon which is placed against an upright standing conduit pipe along with another intermediate member having a thin circular curved portion forming a spud thereon designed to fit inside the internal bore of the opening into the upright standing conduit pipe so that the device is removably secured to the upright standing conduit pipe of the electrical breaker box. The electrical wire is pulled over the pair of pulleys wherein, a first pulley is disposed on an upper end of a movable upper arm and a second pulley is disposed on a bracket spaced away from the upright standing member of the device so as to align the wire with the bore of the upright standing conduit pipe.

摘要： A system for pulling wire behind a wall is provided. One embodiment comprises a cylindrical weight defined by an outside diameter and a first length, and a tubular body with a hollow cavity defined by an inside diameter that is greater than the outside diameter of the cylindrical weight and a second length that is greater than the first length. A distal end of the tubular body includes a tip configured to penetrate a material that is behind the wall, wherein when oriented in a vertical position behind the wall, and wherein in response to drawing the cylindrical weight upward through the tubular body and then releasing the cylindrical weight, the cylindrical weight travels downward towards the distal end of the tubular body and impacts the tip such that momentum of the downward travelling cylindrical weight is transferred to the tip, thereby driving the tubular body downward through the material.

摘要： Various break-resistant anode assemblies and method of installing the same in the ground are disclosed. Each anode assembly basically comprises an anode, at least one pulling cable, and a protective nose cone. The nose cone is a hollow member receiving the leading end of the anode and from which the anode's electrical conductor extends. The nose cone includes a tapered leading surface that facilitates and guides the anode assembly as it is pulled through the ground, while protecting the anode. A break-away mechanism may also be provided to ensure that no more than a maximum pulling force is applied to the anode assembly during its installation to ensure that the anode is not damaged.

摘要： An enhanced apparatus and method for securing a wire to a pulling cable for pulling wire. Specifically, the pulling cable and wire are attached via a pulling head body. The wire is inserted into an end of the pulling head body and secured by crimping the pulling head body against the wire. Further, crimp zone indicators positioned on the outer surface of the pulling head body indicate the optimal zone of crimping to achieve substantial contact between the pulling head body and the wire. A pulling cable is secured to the pulling head body via a ball swage that comprises a tapped surface.

摘要： A pulling device (1) includes one end connectable with a draw-wire (17) and an other end connectable with one or more cable(s) (10) to be pulled. The pulling device (1) includes an inner unit (2) having a conical surface element, wherein one end of the inner unit is connectable with a draw-wire (17). The inner unit (2) is displaceable within a sleeve (7) having a conical surface element. A semi-cone angle (α) of the inner unit and sleeve conical elements is at most the angle corresponding to the self-locking angle determined by the friction coefficient of the cable (10) to be pulled. Clamping of the conical surface elements and the cables (10) therein is provided by a resilient member, preferably a spring (8).
