Abstract

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.

First claim

What is claimed is:

1. A pulling eye comprising:
a body portion defining an interior cavity for receiving a conductor, wherein the body portion comprises
a first indicia applied to the body portion of the pulling eye at a first position on the body portion, and
a second indicia applied to the body portion of the pulling eye at a second position on the body portion that is different from the first position on the body portion of the first indicia, wherein the first indicia has a first configuration that is visually distinct from a second configuration of the second indicia, wherein the first indicia and the second indicia indicate a sequential order for applying a plurality of crimps to the body portion, wherein the first indicia indicates that a first crimp of the plurality of crimps be applied to the first position on the body portion before a second crimp of the plurality of crimps is applied to the second position on the body portion, and wherein the second indicia indicates that the second crimp of the plurality of crimps be applied to the second position on the body portion after the first crimp of the plurality of crimps is applied to the first position on the body portion; and

a head portion.

2. The pulling eye of claim 1 , wherein the first indicia has a first rotational alignment on the body portion, wherein the second indicia has a second rotational alignment on the body portion, and wherein the first rotational alignment of the first indicia on the body portion is different from the second rotational alignment of the second indicia on the body portion.

3. The pulling eye of claim 2 , wherein the first rotational alignment on the body portion of the first indicia and the second rotational alignment on the body portion of the second indicia provide a guide for rotationally aligning a crimping tool at the first position on the body portion to apply the first crimp of the plurality of crimps to the body portion and for rotationally aligning the crimping tool at the second position on the body portion to apply the second crimp of the plurality of crimps to the body portion, respectively.

4. The pulling eye of claim 1 , wherein at least one of the first indicia or the second indicia extends around only a portion of a circumference of the body portion.

5. The pulling eye of claim 1 , wherein the body portion further comprises the first crimp positioned on at least a portion of the first indicia.

6. The pulling eye of claim 5 , wherein the body portion further comprises the second crimp positioned on at least a portion of the second indicia.

7. The pulling eye of claim 1 , wherein the head portion defines an aperture, wherein the pulling eye is part of an assembly of pulling eyes, wherein the assembly of pulling eyes comprises a first pulling member and a second pulling member, wherein the first pulling member is attached to the pulling eye via the aperture, wherein the first pulling member comprises a first loop for attaching the first pulling member to a hook, and wherein the first loop of the first pulling member has a first length that is different from a second length of a second loop attaching the second pulling member to the hook.

8. A pulling eye comprising:
a body portion defining an interior cavity for receiving a conductor, wherein the body portion comprises
a first indicia applied to the body portion of the pulling eye at a first position on the body portion, wherein the first indicia indicates that a first crimp be applied to the body portion at the first position on the body portion, and
a second indicia applied to the body portion of the pulling eye at a second position on the body portion that is different from the first position on the body portion of the first indicia, wherein the second indicia indicates that a second crimp be applied to the body portion at the second position, wherein the first indicia has a first configuration that is visually distinct from a second configuration of the second indicia, and wherein the first indicia further indicates that the first crimp be applied to the first position on the body portion before the second crimp is applied to the second position on the body portion; and

a head portion.

9. The pulling eye of claim 8 , wherein the first indicia has a first rotational alignment on the body portion, wherein the second indicia has a second rotational alignment on the body portion, and wherein the first rotational alignment of the first indicia on the body portion is different from the second rotational alignment of the second indicia on the body portion.

10. The pulling eye of claim 9 , wherein the first rotational alignment on the body portion of the first indicia and the second rotational alignment on the body portion of the second indicia provide a guide for rotationally aligning a crimping tool at the first position on the body portion to apply the first crimp to the body portion and for rotationally aligning the crimping tool at the second position on the body portion to apply the second crimp to the body portion, respectively.

11. The pulling eye of claim 8 , wherein at least one of the first indicia or the second indicia extends around only a portion of a circumference of the body portion.

12. The pulling eye of claim 8 , wherein the body portion further comprises the first crimp positioned on at least a portion of the first indicia.

13. The pulling eye of claim 12 , wherein the body portion further comprises the second crimp positioned on at least a portion of the second indicia.

14. The pulling eye of claim 8 , wherein the head portion defines an aperture, wherein the pulling eye is part of an assembly of pulling eyes, wherein the assembly of pulling eyes comprises a first pulling member and a second pulling member, wherein the first pulling member is attached to the pulling eye via the aperture, wherein the first pulling member comprises a first loop for attaching the first pulling member to a hook, and wherein the first loop of the first pulling member has a first length that is different from a second length of a second loop attaching the second pulling member to the hook.

15. A pulling eye comprising:
a body portion defining an interior cavity for receiving a conductor, wherein the body portion comprises
a first indicia applied to the body portion of the pulling eye at a first position on the body portion, and
a second indicia applied to the body portion of the pulling eye at a second position on the body portion that is different from the first position on the body portion of the first indicia, wherein the first indicia has a first configuration that is visually distinct from a second configuration of the second indicia, and wherein the first indicia and the second indicia indicate a sequential order for applying a plurality of crimps to the body portion; and

a head portion.

16. The pulling eye of claim 15 , wherein the first indicia has a first rotational alignment on the body portion, wherein the second indicia has a second rotational alignment on the body portion, and wherein the first rotational alignment of the first indicia on the body portion is different from the second rotational alignment of the second indicia on the body portion.

17. The pulling eye of claim 16 , wherein the first rotational alignment on the body portion of the first indicia and the second rotational alignment on the body portion of the second indicia provide a guide for rotationally aligning a crimping tool at the first position on the body portion to apply a first crimp of the plurality of crimps to the body portion and for rotation
