Abstract
A sheave for use in a tension measurement system to measure a tension force in a cable may include a first diameter and a second diameter. The sheave is configured to rotate about an axis to orient the first diameter or the second diameter toward the cable, such that a contact force between the sheave and the cable is measured by a tension sensor to determine the tension force in the cable.
Claims19
A tension measurement system for measuring a tension force in a cable comprising:
- a sheave comprising a first diameter and a second diameter, the sheave configured to rotate about an axis to orient the first diameter or the second diameter toward the cable;
- an adjustable support configured to adjust a position of the sheave relative to the cable;
- and
- a tension sensor mechanically coupled to the adjustable support or a base of the tension measuring system to measure the tension force in the cable based on a contact force between the sheave and the cable.
A tension measurement system for measuring a tension force in a cable comprising:
- a sheave comprising a first diameter and a second diameter, the sheave configured to rotate about an axis to orient the first diameter or the second diameter toward the cable;
- an adjustable support comprising a first end to mount the sheave and a second end to control movement of the first end relative to the cable;
- a tension sensor mechanically coupled to the adjustable support or a base of the tension measuring system to measure the tension force in the cable based on a contact force between the sheave and the cable;
- and
- a plurality of tensioners configured to engage with the cable to provide the contact force between the sheave and the cable when the adjustable support positions the sheave adjacent to the cable.
A tension measurement system for measuring a tension force in a cable comprising:
- a sheave comprising a first diameter and a second diameter, the sheave configured to rotate about an axis to orient the first diameter or the second diameter toward the cable;
- an adjustable support configured to adjust a position of the sheave relative to the cable;
- and
- a tension sensor mechanically coupled to the adjustable support or a base of the tension measuring system to measure the tension force in the cable based on a contact force between the sheave and the cable,
- wherein the sheave further comprises:
- a first opening through which a fastener secures the sheave to the adjustable support at the axis;
- and
- a second opening that is offset from the first opening and configured to accept a removable pin, wherein the second opening is arranged to align with a first slot of the adjustable support to orient the first diameter toward the cable, and a second slot of the adjustable support to orient the second diameter toward the cable.
