Abstract

A workstation and method for the installation of a pulling head assembly onto one or more conductors of a cabling system are provided. The workstation incorporates one or more of: a conductor clamp that holds the conductors of the cabling system in place during the installation of the pulling head assembly; a cutting guide having indicia marks that indicate the lengths to which to cut the conductors in order to achieve a staggered pattern of pulling eyes attached to the conductors in the pulling head assembly; a stripping tool that is used to remove a portion of the insulation from the terminal end of each conductor so that the end of the conductor may be inserted into the pulling eye; and a crimping tool that is used to crimp the pulling eyes onto the terminal ends of each of the conductors.

Claims (28)

1. A method comprising:

receiving a plurality of conductors;

cutting each of the plurality of conductors to a respective length such that the plurality of conductors are cut in a staggered pattern; and

crimping a pulling eye onto a terminal end of each of at least a portion of the plurality of conductors using a crimping tool.

2. The method of claim 1 , wherein a guide is used when cutting each of the plurality of conductors such that the plurality of conductors are cut in the staggered pattern.

3. The method of claim 2 , wherein the guide comprises a plurality of indicia markings.

4. The method of claim 1 , further comprising after receiving the plurality of conductors, engaging a clamp to hold each of the plurality of conductors in place.

5. The method of claim 1 , further comprising removing, using a stripping tool, a portion of an insulation from the terminal end of at least the portion of the plurality of conductors.

6. The method of claim 5 , wherein the stripping tool comprises a plurality of drive motors, each of the plurality of drive motors having a stripping head removably attached that is configured to accommodate a conductor of differing diameter.

7. The method of claim 1 , wherein the crimping tool is configured to be rotated 90 degrees such that multiple crimps are made on the pulling eye, wherein the multiple crimps are oriented approximately 90 degrees from each other.

8. The method of claim 1 , wherein crimping the pulling eye onto the terminal end of each of at least the portion of the plurality of conductors comprises:

positioning the crimping tool at a first position on the pulling eye;

crimping, using the crimping tool, the pulling eye at the first position;

rotating the crimping tool to a second position on the pulling eye; and

crimping, using the crimping tool, the pulling eye at the second position, wherein the first position and the second position are rotated from each other.

9. A method comprising:

cutting each of one or more conductors to a respective length;

removing, using a stripping tool, a portion of an insulation from a terminal end of each of the one or more conductors having the insulation; and

crimping a pulling eye onto the terminal end of each of the one or more conductors using a crimping tool, wherein the respective length to which to cut each of the one or more conductors is determined based on achieving a staggered pattern of pulling eyes when the pulling eyes are crimped onto the one or more conductors.

10. The method of claim 9 , wherein the staggered pattern of the pulling eyes when the pulling eyes are crimped onto the one or more conductors is achieved using a guide.

11. The method of claim 10 , wherein the guide comprises a plurality of indicia markings.

12. The method of claim 9 , wherein the stripping tool comprises a plurality of drive motors, each of the plurality of drive motors having a stripping head removably attached that is configured to accommodate a conductor of differing diameter.

13. The method of claim 9 , wherein the crimping tool is configured to be rotated 90 degrees such that multiple crimps are made on each of the pulling eyes, wherein the multiple crimps are oriented 90 degrees from each other.

14. The method of claim 9 , wherein crimping the pulling eye onto the terminal end of each of the one or more conductors comprises:

positioning the crimping tool at a first position on the pulling eye;

crimping, using the crimping tool, the pulling eye at the first position;

rotating the crimping tool to a second position on the pulling eye; and

crimping, using the crimping tool, the pulling eye at the second position, wherein the first position and the second position are rotated from each other.
