Abstract
A protective system having a protective device for tension members for collecting ice accumulations detaching from a tension member that is anchored on the structure in a first abutment and in a second abutment. The tension member is exposed to climatic conditions by the section running between the abutments. To guarantee protection from falling ice accumulations, the protective device has a hose-shaped envelope, which surrounds the tension member on the circumferential side. The hose-shaped envelope is disposed on a partial longitudinal section of the tension member in an axially compressed or folded manner in a first operating position, and is movable, with the aid of a drive system, to a second operating position, in which the hose-shaped envelope extends over the length of the tension member in the stretched state.
