Conductor line, festoon, buffers, limiters
Energy feed and safety parts that keep a crane legal.
Festoon for short runways, conductor bar when several crabs share a rail. Buffers, limit switches and load limiters are not optional on a new machine.
When it fits
A new crane needs feed and limits on the same ticket. A frayed festoon on an old bay is a parts identification, then electrical repair.
Duty and steel
Current, travel length and how many trolleys share the bar set the feed. Duty also sets how often buffers actually work.
Interface
Earth, isolator, festoon or conductor bar, and the radio or pendant share one diagram. Mixing a safe-area spare into an ATEX gland is how the package fails.

Electrical repair is the cluster for faults. ATEX service is the zone package. The parts desk matches a torn festoon to the plate.
