18-2 Double Cross Catenary Clamp
Double-groove clamp gripping two cross catenary strands for heavy head-span suspension points.
Specifications
| Model | 18-2 |
|---|---|
| Drawing No. | 18-2 |
| Standard | TB/T 2075.18-2024 — Part 18: Head-span suspension devices |
| Installation | Clamped on twin cross catenary strands, suspending members at heavy head-span points |
The 18-2 double cross catenary clamp serves head-span structures built with two parallel cross catenary strands: its twin-groove body grips both wires at once, so the suspension load is shared by the two strands and the carrying capacity of the suspension point is significantly raised — the choice for long-span, multi-track stations.
Load sharing between the strands is balanced by the common groove body, and the ear interfaces remain standard for the suspension fittings, so the same hangers and upper fixed ropes attach as with the single clamp.
Design Features
- Twin grooves grip two strands simultaneously with balanced loading
- High carrying capacity for long-span, multi-track head-spans
- Standard ear for suspension members
- 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. Where the head-span uses two parallel cross catenary strands — typically long spans and many tracks — the 18-2 grips both strands so they share the load. Yes — the common twin-groove body holds both wires in one rigid grip, so the suspension load is shared rather than carried by one strand. Yes — the ear interface is the same standard as the single clamp, so suspension members attach unchanged. TB/T 2075.18-2024 — Part 18: Head-span suspension devices.Frequently Asked Questions

Performance
Operating Conditions
Outdoor service at long-span, multi-track station head-spans with elevated suspension loads.
Mechanical Performance
Both strands share the suspension load through the common body, raising point capacity; grip holds both strands without slip.
Applications
Long-Span Stations
Wide head-spans over many tracks.
Heavy Suspension Points
Two strands share each point load.
Standard Assemblies
Same ear as the 18-1 family.
Harsh Climates
Anti-corrosion finish for outdoor duty.
