1. Definition
A trough-type cable tray roll forming line cold-forms steel strip into channel-style cable trough sections. A common reference flow is decoiling, leveling, punching, hydraulic shear, conveying, roll forming, and discharge. Some setups use pre-cut logic: punch and shear to length before the forming section. This page covers the trough family — not perforated tray or ladder tray.
2. Width tiers (reference, not one machine)
| Tier | Width reference | Speed / power notes (FAQ) |
|---|---|---|
| Narrow (100–300) | ~100–300 mm side adjust | Forming often ~3–6 m/min; thickness tiers ~0.7–1.5 mm in different docs — confirm source |
| Mid (100–600) | ~100–600 mm (some docs from 50 mm) | Forming ~3–6 m/min on English trough docs; pre-cut totals can reach ~94.5 kW installed — confirm scope |
| Large (BIG) | ~75–750 mm class | Punch ~3–8 m/min; total ~77.2 kW; forming motor ~32 kW; ~14 stands, shaft ~φ120 |
Market cable-tray lines advertise wide thickness and width bands — use them as industry context; keep ZTRFM tier files side by side on the proposal.
3. Process route
- Decoiling and leveling
- Servo feeding into the punch zone
- Punching
- Hydraulic shear (pre-cut setups)
- Conveying into the forming section
- Roll forming and discharge
Optional cover-cap forming may be included by configuration. Connector plates are accessories, not part of the main line rating.
4. Reading speed and power correctly
- Forming speed alone does not describe output when punch or shear cadence is slower on pre-cut lines
- Do not publish perforated punching ~6–8 m/min / forming ~10–15 m/min / ~80 kW as trough ratings
- Conflicting host kW across English, U100-600, YX, and Egypt docs → contract configuration wins; do not force one public “truth”
5. Applications
- Channel-style / trough cable tray production for commercial and industrial cable management
- Optional cover production when the trough proposal includes a cover path
6. Buyer FAQ
Is pre-cut a different product line?
No. Pre-cut vs post-cut is a configuration variant inside the trough soft-model family — not a reason to invent a new line ID.
Can I quote BIG 77.2 kW for a 100–300 inquiry?
No. Keep large-tier power on the BIG soft model unless the proposal explicitly covers that width class.
Perforated tray on this page?
No — different line / soft model. See the perforated vs trough boundary entry.
7. Inquiry checklist
- Finished profile drawing or sample section with critical dimensions
- Material grade, thickness range, and coating
- Target output class (m/min or pieces/hour) and cut-length range
- Punching map / shear preference when applicable
- Voltage / frequency and any PLC or HMI brand preferences
- Named soft-model / quotation tier — do not merge sibling parameter files
Final ratings follow the named proposal. Price and lead time are out of scope.
