ROAD II/479 OSTRAVA, MÚK BAZALY, PHASE I

Investor: Moravskoslezský kraj

Customer: Strabag a.s.

Technical Data, Description:

During the repair of the bridge, the reconstruction of the overhead contact line had to be divided into several stages. In the first phase the right half of the bridge was repaired, so it was necessary to transfer the trolleybus transportation during the reconstruction to the left side of the bridge. Part of the reconstruction was the exchange of TV poles on the right side of the bridge. EŽ Praha provided delivery, disassembly and assembly of masts and overhead contact lines. Due to the higher load on the reconstruction, a part of the existing masts (10 pcs) on the left side was reinforced with an additional reinforcement. Subsequently, the traction line was moved in the direction of Bazaly from the right to the left. The provisional line was simple, non-tensioned, suspended on long fiberglass cantilevers by means of delta hinges and flexible arc clips.

After completing the repair of the communications and the position of the new masts, the traction line was restored in the original geometry. The new TV is simple, non-tensioned, the contact wire is Cu 100 mm². Part of the construction was the delivery and installation of two new electric switches, one mechanical switch and one crossing. The total length of the contact wire is 3850 m.
