Abstract

A cable puller includes a frame, a capstan mounted on the frame around which a pulling rope is wrapped, and a sensor configured to measure the distance the pulling rope travels relative to the frame. The sensor may be a Hall effect sensor and/or an optical sensor.

First claim

What is claimed is:

1. A gauge device for use with a cable puller, the gauge device configured to measure a distance a pulling rope travels during a cable pull, the gauge device comprising:
a frame;
a roller rotatably mounted to the frame;
a computing module and an output display mounted together in an enclosure, the enclosure operatively mounted to the frame; and
a sensor in operative communication with the roller and configured to provide distance measurement data to the computing module representative of the distance the pulling rope travels relative to the frame during a cable pull, wherein the gauge device is operatively separate from the cable puller.

2. The gauge device of claim 1 , wherein the sensor is a Hall effect sensor configured to sense positions of a plurality of magnets mounted on the roller.

3. The gauge device of claim 1 , wherein the computing module is configured to receive information from the sensor and calculate the distance that the pulling rope has traveled in response to receipt of the information.

4. The gauge device of claim 1 , wherein the output display provides a graphical representation of the distance the pulling rope has traveled during a cable pull.

5. The gauge device of claim 1 , wherein the output display provides a graphical representation of a tension acting on the pulling rope and a speed of the pulling rope, during the cable pull.

6. The gauge device of claim 1 , wherein the sensor is an optical sensor.

7. The gauge device of claim 1 , further including a compression load sensor operatively coupled to the roller and configured to measure a force exerted on the roller by the pulling rope during a cable pull.

8. The gauge device of claim 7 , wherein the compression load sensor provides load data to the computing module during a cable pull.

9. The gauge device of claim 1 , further including a wirelessly coupled communication device physically remote and separate from the gauge device, the communication device in operative bidirectional communication with the computing module.

10. The gauge device of claim 9 , wherein the communication device includes a display screen configured receive and/or display real-time data corresponding to the cable pull and configured to receive archived data corresponding to one or more historical cable pulls.

11. The gauge device of claim 9 , wherein the communication device provides at least one of an audio indication, visual indication, and tactile indication, that a predetermined threshold has been met regarding a current cable pull.

12. The gauge device of claim 11 , wherein data regarding the predetermined threshold is provided to the communication device by the computing module.

13. A gauge device configured to measure a distance a pulling rope travels during a cable pull, the gauge device comprising:
a frame;
a roller rotatably mounted to the frame;
a computing module and an output display mounted together in an enclosure, the enclosure operatively mounted to the frame; and
a sensor in operative communication with the roller and configured to provide distance measurement data to the computing module representative of the distance the pulling rope travels relative to the frame during a cable pull, wherein the gauge device is operatively separate from the cable puller.

14. The gauge device of claim 13 , wherein the gauge device is operatively positioned and mounted relative to a cable puller.

15. The gauge device of claim 13 , further including a wirelessly coupled communication device physically remote and separate from the gauge device, the communication device in operative bidirectional communication with the computing module.

16. The gauge device of claim 15 , wherein the communication device includes a display screen configured receive and/or display real-time data corresponding to the cable pull and configured to receive archived data corresponding to one or more historical cable pulls.

17. The gauge device of claim 15 , wherein the communication device provides at least one of an audio indication, visual indication, and tactile indication, that a predetermined threshold has been met regarding a current cable pull.

18. The gauge device of claim 17 , wherein data regarding the predetermined threshold is provided to the communication device by the computing module.

19. The gauge device of claim 13 , further including a compression load sensor operatively coupled to the roller and configured to measure a force exerted on the roller by the pulling rope during a cable pull.

20. The gauge device of claim 19 , wherein the compression load sensor provides load data to the computing module during a cable pull.
