Abstract
Official abstract text for this publication.
A combination includes a cable puller having a capstan around which a pulling rope is wrapped, and a sensor configured to measure the distance the pulling rope travels during a pulling operation. The sensor may be a Hall effect sensor and/or an optical sensor.
First claim
Opening claim text (preview).
What is claimed is: 1. A combination for use in pulling rope comprising: a cable puller having a capstan around which a pulling rope is wrapped, wherein rotation of the capstan causes the pulling rope to travel during a pulling operation; and a sensor configured to measure a distance the pulling rope travels during the pulling operation. 2. The combination of claim 1 , wherein the sensor is a Hall effect sensor which senses positions of magnets mounted on a roller, wherein the pulling rope travels around the roller. 3. The combination of claim 1 , further comprising control circuitry configured to receive information from the sensor and to calculate the distance the pulling rope has traveled in response to receipt of the information. 4. The combination of claim 3 , further comprising a display operatively coupled to the control circuitry and on which the distance the pulling rope has traveled is displayed. 5. The combination of claim 1 , wherein the sensor is an optical sensor. 6. The combination of claim 1 , further comprising a boom on which the sensor is mounted. 7. The combination of claim 6 , wherein the sensor is a Hall effect sensor which senses positions of magnets mounted on a roller rotatably coupled to a frame on the boom, wherein the pulling rope travels around the roller. 8. The combination of claim 6 , wherein the sensor is an optical sensor.
