The installation comprises a uni-line drive assembly incorporating a stretched drive guy rope provided at each end with a swivel joint, a driven rotating element and a pair of driving pulleys, the former and the latter being firmly secured to the stretched drive guy rope. A pair of driven pulleys is opposed to the pair of driving pulleys. A pair of endless cables is tensioned between the driving and driven pulleys and each endless cable has an upper path and a lower path. A pair of stretched guide ropes, essentially parallel to the pair of endless cable is used. Each one of the stretched guide ropes is perpendicularly disposed to the stretched drive guy rope and extends from the ends of the latter. At least a pair of carrying lines is perpendicularly disposed with respect to the pair of stretched guide ropes. One carrying lines is attached to the upper paths, while another is attached to the lower paths, each end of each carrying line being slidably engaged with an adjoining one of the pair of stretched guy guide ropes. An actuating assembly includes a reversible electric motor connected to a reduction gear drive that is provided with an output drive shaft. On the latter, a drive wheel is securely fastened and transmits, via a mechanical transmission, a torsional moment to the driven wheel. The endless cable is provided with devices for triggering a change of direction of the reversible motor. A multiplicity of birds scare devices arranged in intervals on each carrying line is used. The latter devices are attached to the upper and lower paths at opposite positions, adjacent the driven pulley and the driven pulley, and act when the upper and the lower path, alternatively, at an end of their traveling paths come close to the driving pulley.
