A cable conveyance attachment assembly adapted to be operatively connected to a host vehicle and a length of cable. The assembly includes a frame, a mounting plate that is attached to the frame, at least one drum that is rotationally attached to the frame, and a fluid conduit that is operatively connected to the host vehicle and the at least one drum. The at least one drum is adapted to pull the length of cable, and the mounting plate is adapted to removably attach the cable conveyance attachment assembly to the host vehicle. A method for conveying cable including providing a cable conveyance attachment assembly and conveying the length cable to at least one drum.

Method for installing an elongated element, in a submarine duct, the submarine duct having an entry port and an exit port located in outer liquid (OL) at a second depth,

the method comprising the steps of: introducing the elongated element into the entry port, introducing propelling liquid (PL) into the entry port,
characterized in that the method comprises a step of sucking propelling liquid (PL) out of the exit port of the duct with an immerged suction pump being operated at a predetermined suction pressure drop (ΔP.sub.pump) of propelling liquid (PL) so that the predetermined suction pressure drop (ΔP.sub.pump) applied to propelling liquid (PL) is smaller than a hydrostatic pressure (P.sub.hydro) of the outer liquid (OL) at the second depth.

Described herein is a fish tape reel comprising a housing with two side shells coupled together. The housing defines an internal cavity. An internal portion of the housing defines a plurality of flat gripping portions and a plurality of finger notches. The housing comprises a plurality of tabs in the internal cavity, the tabs interfacing against an inner annular portion that is coupled to the handle when the handle rotates around the housing.

The present invention relates to a fish tape drilling attachment device primarily comprised of a housing, further comprised of at least one bearing, at least one shaft, at least one cam, and at least one cam lever. A fish tape can be fed through the housing such that it is contacted by the cam, wherein the shaft can spin freely within the housing via the bearing such that the hammer action of the drill causes the fish tape to act like a spring in order to slowly move the fish tape through a piece of conduit.

A device to automate or semiautomate a fish tape is provided that can include an attachable handle with battery operated motor, rollers, gears and controls that can be integrated into its own or existing fish tape spools. Another embodiment provides a left and right plate and an assembly about a member to be driven by a crank or other automated means to mobilize a fish tape which over comes the limitations of existing manual and automatic fish tapes making it safer, more efficient and easier for an operator to pull wire.

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.

A repairing tool for an electric wire threading head for pressing and squeezing a drawing-in wire of the electric wire includes a first holding part, a second holding part opposite to the first holding part, and two positioning bolts for fastening the first holding part and the second holding part. A first half screw hole and a second half screw hole are protrudingly formed on the first holding part and the second holding part to form a complete screw hole. The drawing-in wire is pressed and squeezed through the positive rotation or reverse rotation of the repairing tool to form an external screw thread part and increase a screw thread area, and the surface of the external screw thread part is applied with instant dry adhesive and rotated into a pulling head, so that the drawing-in wire is closely adhered to the pulling head and tensile strength is improved.

An end piece is provided for guiding a needle intended to be inserted in a sheath occupied by at least one installed cable. The end piece includes: a free first end referred to as a head of a shape suited to slipping in between an internal wall of the sheath and the at least one installed cable; a second end fixed to the needle; and a part connecting the two ends and referred to as a shank. The shank has a flexibility that increases toward the head.

The invention relates to a method of laying and connecting cable between a first structure and a second structure. The first and second structures may be turbine towers or other structures positioned in a body of water. The method includes the step of connecting a second end laying mechanism on the second structure for engagement with a second end portion of the cable. The second end portion of the cable is then engaged with the second end laying mechanism to form a catenary of cable at one side of the second end laying mechanism between the first and second structures, and a tail section at the other side of the second structure. The height of the second end laying mechanism is then adjusted to allow connection of the second end of the cable to the second structure. Second end laying and connecting apparatus for facilitating the laying and connecting of cable between first and second structures is also provided.

A fish tape case is configured to house a fish tape in accordance with some example embodiments is provided. The fish tape includes a shell having a rotatable tray therein. A fish tape extends through openings in the shell and the tray. The fish tape case does not include a handle.
