Saddle clamp with double-bolt plate that presses the tube suspender end onto the positioning tube.
Specifications
| Model | Positioning tube clamp |
|---|---|
| Standard | TB/T 2075.3-2024 — Part 3: Limit-type positioning devices |
| Materials | Hot-dip galvanized steel |
| Installation | Sleeved on the positioning tube, pressing the suspender rope end to the tube |
The positioning tube clamp is a saddle-type clamp with a double-bolt pressure plate, sleeved directly on the positioning tube body. It presses the lower end of the 3-7B tube suspender rope against the tube side, completing the tube's suspension system together with the 3-8 suspender hook on the cantilever.
The clamp slides along the tube before tightening, so the suspender point can be set exactly to the assembly dimensions during pre-configuration. Hot-dip galvanized construction suits long outdoor service.
Design Features
- Saddle clamp with double-bolt plate — reliable grip, easy to fit and remove
- Sleeve mounting with axial adjustment along the tube
- Common part with the tube suspender rope and suspender hook
- Hot-dip galvanized for long-term 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. The lower end of the 3-7B tube suspender rope: the saddle clamp presses the rope end fitting against the positioning tube, fixing the suspension point. It slides along the tube before the bolts are tightened, so the suspension point is set to the pre-assembly dimensions exactly. The 3-8 suspender hook on the flat cantilever holds the rope's upper end; the tube clamp holds the lower end — together they hang the tube level. Yes — the body is hot-dip galvanized steel for long outdoor service.Frequently Asked Questions

Performance
Operating Conditions
Outdoor service at OCS registration points on mainline, high-speed and station structures, subject to suspension, wind, ice and dynamic pantograph loads as defined by the OCS design.
Mechanical Performance
Double-bolt pressure plate holds the suspender end without slip; saddle shape distributes the clamp load on the tube.
