MAINTENANCE 79
8.2 Contact line
For normal use, the conductor system requires only little maintenance. The following tasks should be per-
formed periodically however.
In case of damage to the conductor system, the associated components such as current collectors must be
inspected for damage.
Replacing the conductor system
Usually, the wear of the conductor system cannot be measured. If maintenance intervals are kept, then life-
times of 15-20 years and more can be achieved.
Interval Service/monitoring Personnel

monthly • Visual inspection of general condition. Replace damaged/de-
fective parts.
• Check mechanical and electrical connections, especially at the
feed terminals; re-tighten if necessary.
• Remove small burns or discolorations on the contact surface by
scouring with an abrasive pad (min. grit size 400). Do not use a
powered brush. If removing the burns is not possible, then re-
place the relevant section of the conductor system.
