Work continues on the railway line Munich – Verona, involving the replacement of the catenary contact line support wires, 610 mmq section, on the stretch from Fortezza to Le Cave.
The work on the Electric Traction plants is linked to the construction of the “Isarco Underpass” for the Brenner base tunnel.
The “conductor renewal” works are carried out using a train made up of 6 railway vehicles and 12 people:
- Multi-purpose boom lift APV 320 D
- Unwinding car CRC6000
- Motorized ladder RSM16
- Motorized ladder RSM SPAZIO 8
- Motorized ladder RSM SPAZIO 8
- Braked tensioning wagon for the contact line 7000BS-100
The activities, in sequence, mainly consist of:
- installation of “temporary” wire pulley blocks
- threading the 2 wires for each R.A. support
- placing the wires in the wire pulley blocks
- passing the suspension fittings from existing wires to new wires
- arranging the arrival and departure anchoring points for the 2 new wires;
- 1st tensioning of the line
- “jumping” the wires, i.e., moving the wires from temporary pulley blocks to wire-support brackets on the suspension insulator
- Final tensioning of the line to the required pulling force
- Removal of the “temporary” wire pulley blocks
- Removal of the existing wires
