Abstract

An apparatus for applying a terminal end of a cable includes a base plate having a threaded rod support, and a threaded rod inserted through an aperture of the threaded rod support. The apparatus further includes an anchor coupled to the base plate and configured to couple a terminal end body of a cable to the apparatus, and a cinch trolly slidebly coupled to the base plate via a groove. The cinch trolly includes a protrusion configured to couple a cable pulling clamp to the cinch trolly, and one or more threaded nuts configured to threadably couple the cinch trolly to the threaded rod. The cinch trolly is configured to move along the groove away from the anchor when the threaded rod is rotated, thereby pulling the cable away from the anchor via the cable pulling clamp and thereby cinching the cable and a wedge within the terminal end body.

First claim

What is claimed is:

1 . An apparatus for applying a terminal end of a cable, the apparatus comprising:
a base plate comprising a threaded rod support; a threaded rod inserted through an aperture of the threaded rod support; an adapter coupled to a first end of the threaded rod and configured to couple a torque tool to the threaded rod; an anchor coupled to the base plate and configured to couple a terminal end body of a cable to the apparatus; and a cinch trolly slidebly coupled to the base plate via a groove in the base plate, the cinch trolly comprising:
a protrusion configured to couple a cable pulling clamp to the cinch trolly; and
one or more threaded nuts configured to threadably couple the cinch trolly to the threaded rod;
wherein the cinch trolly is configured to move along the groove away from the anchor when the threaded rod is rotated by the torque tool, thereby pulling the cable away from the anchor via the cable pulling clamp and thereby cinching the cable and a wedge within the terminal end body.

2 . The apparatus of claim 1 , further comprising a plurality of torquing posts that are each configured to secure the terminal end body while a predetermined amount of torque is applied to a cable clamp attached to the cable.

3 . The apparatus of claim 2 , wherein the plurality of torquing posts comprises:
a first torquing post having a first diameter; and a second torquing post having a second diameter that is different from the first diameter.

4 . The apparatus of claim 2 , wherein:
the plurality of torquing posts are welded to the base plate; or the plurality of torquing posts are removably coupled to the base plate.

5 . The apparatus of claim 1 , wherein:
the threaded rod support is an angle bracket welded to the base plate; and the angle bracket and the anchor are coupled to opposite ends of the base plate.

6 . The apparatus of claim 1 , wherein:
the anchor is welded to the base plate; or the anchor is removably coupled to the base plate.

7 . The apparatus of claim 1 , wherein the base plate comprises a plurality of holes configured to allow a bar to be used to manually advance the cable pulling clamp away from the anchor.

8 . The apparatus of claim 1 , wherein the anchor comprises:
a plurality of pin apertures, wherein the terminal end body is coupled to the anchor by a pin that is inserted through the terminal end body and the pin apertures; and a milled groove that is sized to accept the cable.

9 . The apparatus of claim 1 , wherein the protrusion is a hook that is aligned with the anchor.

10 . The apparatus of claim 1 , wherein the cinch trolly comprises:
an angle bracket; a bolt with a locknut configured to secure the cinch trolly to the base plate through the groove; and a key coupled to the angle bracket and configured to fit into the groove of the base plate.

11 . A system for applying a terminal end of a cable, the system comprising:
a cable pulling clamp; a terminal end body for a cable; a wedge configured to be inserted into the terminal end body; and a cable terminal end cinch tool comprising:
a base plate comprising a threaded rod support;
a threaded rod inserted through an aperture of the threaded rod support;
an adapter coupled to a first end of the threaded rod and configured to couple a torque tool to the threaded rod;
an anchor coupled to the base plate and configured to couple the terminal end body to the cable terminal end cinch tool; and
a cinch trolly slidebly coupled to the base plate via a groove in the base plate, the cinch trolly comprising:
a protrusion configured to couple the cable pulling clamp to the cinch trolly; and
one or more threaded nuts configured to threadably couple the cinch trolly to the threaded rod;

wherein the cinch trolly is configured to move along the groove away from the anchor when the threaded rod is rotated by the torque tool, thereby pulling the cable away from the anchor via the cable pulling clamp and thereby cinching the cable and the wedge within the terminal end body.

12 . The system of claim 11 , the cable terminal end cinch tool further comprising a plurality of torquing posts that are each configured to secure the terminal end body while a predetermined amount of torque is applied to a cable clamp attached to the cable.

13 . The system of claim 11 , wherein the base plate comprises a plurality of holes configured to allow a bar to be used to manually advance the cable pulling clamp away from the anchor.

14 . The system of claim 11 , wherein the cinch trolly comprises:
an angle bracket; a bolt with a locknut configured to secure the cinch trolly to the base plate through the groove; and a key coupled to the angle bracket and configured to fit into the groove of the base plate.

15 . A method of applying a terminal end to a cable, the method comprising:
coupling a terminal end body to an anchor of a cable terminal end cinch tool; looping an end of a cable through the terminal end body; inserting a wedge into the terminal end body; attaching a cable pulling clamp to the cable and to a cinch trolly of the cable terminal end cinch tool; advancing the cinch trolly away from the anchor in order to cinch the cable and the wedge within the terminal end body; applying a cable clamp to the cable; removing the terminal end body from the anchor; placing the terminal end body on a torquing post of the cable terminal end cinch tool; and applying a predetermined amount of torque to the cable clamp.

16 . The method of claim 15 , wherein advancing the cinch trolly away from the anchor in order to cinch the cable and the wedge within the terminal end body comprises using a torque tool to rotate a threaded rod that is threadably coupled to the cinch trolly.

17 . The method of claim 15 , wherein advancing the cinch trolly away from the anchor in order to cinch the cable and the wedge within the terminal end body comprises:
coupling a bar to the cinch trolly; and manually prying the cinch trolly away from the anchor using a plurality of holes in a base plate of the cable terminal end cinch tool.

18 . The method of claim 15 , wherein coupling the terminal end body to the anchor of the cable terminal end cinch tool comprises inserting a pin through the terminal end body and pin apertures of the anchor.

19 . The method of claim 15 , wherein applying the predetermined amount of torque to the cable clamp comprises utilizing a torque wrench.

20 . The method of claim 15 , wherein the cable terminal end cinch tool comprises:
a base plate comprising a threaded rod support; a threaded rod inserted through an aperture of the threaded rod support; the anchor; and the cinch trolly, wherein the cinch trolly is slidebly coupled to the base plate via a groove in the base plate, the cinch trolly comprising:
a protrusion configured to couple the cable pulling clamp to the cinch trolly; and
one or more threaded nuts configured to threadably couple the cinch trolly to the threaded rod.
