Abstract

The structural cable of a construction work comprises a bundle of load-bearing tendons, a sheath within which the bundle of tendons is located, and at least one vibration module received within the sheath and configured to generate vibrations to break superficial ice or frost deposits on the cable.

First claim

The invention claimed is:

1. A structural cable of a construction work, the structural cable comprising:
a bundle of load-bearing tendons;
a sheath within which the bundle of tendons is located; and
at least one vibration module received within the sheath and configured to generate vibrations to break superficial ice or frost deposits on the cable.

2. The structural cable of claim 1 , wherein the at least one vibration module comprises a vibration engine, the vibration engine being configured to generate vibrations having one or more frequencies.

3. The structural cable of claim 2 , wherein the one or more frequencies comprise frequencies of at least 20 Hz.

4. The structural cable of claim 1 , further comprising a housing within the sheath and fixed relative to the sheath, said housing having a concavity turned towards a longitudinal region of the sheath which includes openings, to define a cavity, extending longitudinally relative to the sheath, wherein the bundle of tendons is located outside the housing and the cavity.

5. The structural cable of claim 4 , wherein the at least one vibration module is arranged in the cavity.

6. The structural cable of claim 4 , wherein the housing is bonded to an inner surface of the sheath.

7. The structural cable of claim 4 , wherein the housing comprises a plurality of longitudinal segments aligned with one another along the length of the structural cable.

8. The structural cable of claim 4 , wherein the housing is substantially continuous longitudinally relative to the sheath.
