Description

Copper Shoe with Holder is a replaceable current-collecting contact set used in CMK bolt-joint / DSL shrouded busbar current collectors. The copper (often copper-graphite) shoe slides on the busbar conductor to pick up power, while the insulated holder secures the shoe and maintains correct contact pressure. This spare assembly is designed for high conductivity, low friction, and reduced arcing, helping current collectors perform smoothly over long crane travel paths and across busbar joints. Quick replacement of the shoe/holder reduces downtime and maintenance cost.
