4. Perform an overall check of trolley parts such as
collectors and pantographs.
Guiding and Stabilizing Wheels
Tracking and stabilizing wheels absorb vibrations
and force coming from the trolley movement and rail
junctions.
Estimated lifetime for these wheels is 10000km;
therefore, no replacement should be expected.
However, for safety reasons, check for lateral
excess movement of the bearings.
Sliding Collectors
When copper collectors are worn, the plastic
support can slide against the PVC holder. This will
generate noise and dust and can potentially
deteriorate the PVC holder.
Check the height between the contact surface and
the bottom of the plastic support. New contacts are
20mm thick. As shown below, if the collector is worn
more than 3mm, replace it. Estimated lifetime for
contacts is 8000km.
