Protection system for tension members of a structure for collecting ice accumulations detaching from a tension member

A protective system for tension members of a structure, in particular for a cable stay of a bridge structure, the protective system comprising:

• a tension member anchored on the structure in a first abutment by a first end and in a second abutment by a second end, and being exposed to climatic conditions by the section running between the abutments;
• a protective device for the tension member for collecting ice accumulations detaching from the tension member, the protective device comprising a hose-shaped envelope, which surrounds the tension member on a circumferential side, the hose-shaped envelope being disposed in an axially compressed or folded manner on a partial longitudinal section of the tension member in a first operating position, and extending over a length of the tension member in a stretched state in a second operating position;
• and
• a drive device via which the hose-shaped envelope is movable from the first operating position to the second operating position.
