Improper replacement of sliding strips
Damages of pantograph and infrastructure
Always replace sliding strips (or collector strips) as pairs.
As a guide line to determine the intervals between visual inspections, please
consider the following:
• Anticipated operating and wear life.
• Extreme weather conditions (ice, snow, rain, sleet, etc.).
The sliding strips need to be checked for damage and wear at every visual
inspection:
The wear of both sliding strips should happen evenly.
If wear is uneven:
• Check adjustment of parallel guide ( Chapter #14.12).
• Check if pan head suspension or other parts of the pan head are damaged.
