18-1 Cross Catenary Clamp
Strand clamp for head-span cross catenary wires, with ear for suspending the upper fixed rope.
Specifications
| Model | 18-1 |
|---|---|
| Drawing No. | 18-1 |
| Standard | TB/T 2075.18-2024 — Part 18: Head-span suspension devices |
| Installation | Clamped on the head-span cross catenary wire, suspending the upper fixed rope |
The 18-1 cross catenary clamp is installed at the suspension points of a head-span structure's cross catenary wire: its clamp groove grips the steel strand and its ear connects the upper fixed rope and suspension members, delivering the loads of several tracks' contact suspensions into the head-span.
The groove profile matches the strand so the grip is firm without slip, the ear interfaces are standard for the head-span fittings family, and the node positions can be laid out flexibly to follow the track spacings of the station.
Design Features
- Clamp groove matched to the strand — firm grip without slipping
- Standard ear for suspension members and upper fixed ropes
- Node layout flexible, following different track spacings
- Anti-corrosion finish for outdoor service
The product is manufactured under CRCC railway product certification and an ISO 9001 quality management system, with incoming material inspection, in-process control on critical operations and batch-by-batch final inspection before delivery.
Henan Chuangwit Railway Equipment Co., Ltd. supplies this locator with selection calculations, matched fittings and site technical guidance for traction power projects. A station arrangement where a cross catenary wire spans several tracks between two masts, and each track's suspension hangs from it — used where masts between every track are impractical. It clamps the cross catenary strand at each suspension point and provides the ear from which the upper fixed rope and suspension members hang. No — the groove matches the strand profile and the clamping force is sized to hold without slip under unbalanced track loads.
