Flexible catenary hanger without thimble
adjustable and spark free conducting
The KRUCH hanger without thimble is a complete new approach for a safe, current-proof suspension of catenary wires, excellent to assemble and regulate. Installation is done by one screw only, first fixing the dropper cable (also called drop wires), secondly the contact wire / catenary cable, designated for automated workshop-preassembly and rapid “on track” installation. Reject due to false-length of hangers is minimised – the hanger can be regulated at any time.
The spark-free & current-proof connection replaces all other electrical jumpers and balances the electrical potential in the system at each dropper (improved system performance, reduced wear).
The flexible “hanger without thimble” by KRUCH is the first choice for modern railways with focus on installation time and electrical performance!
