Cable Tray Roll Forming Lines: Trough vs Perforated Tray Types
Table of Contents
1. Definition
Buyers often search for one “cable tray machine.” In practice, trough-type (channel / solid-bottom style) and perforated tray-type lines differ in process emphasis, speed reading, and power balance. Width tiers within trough lines also differ. Ladder-tray welding systems are outside this page’s boundary.
2. Line-type comparison
| Type | Typical output | Process emphasis | Do not confuse with |
|---|---|---|---|
| Trough tray line (width tiers) | Channel-style cable trough | Often punch + shear + form; pre-cut common | Not perforated-tray speed/power tables |
| Perforated tray line | Tray bridge with dense hole patterns | Heavy press punching before dual-arm forming | Not trough 3–6 m/min English tables |
3. Trough width tiers (same line family, different soft models)
| Tier soft model | Width reference | Keep separate |
|---|---|---|
| Narrow (100–300) | ~100–300 mm class | Do not publish BIG 75–750 power as this tier’s only answer |
| Mid (100–600) | ~100–600 mm (some docs from 50 mm) | Pre-cut total installed power may be high — confirm scope |
| Large (BIG) | ~75–750 mm class | Punch ~3–8 m/min / total ~77.2 kW references stay on BIG |
4. Before you sign
- Confirm tray type first: trough channel vs perforated tray
- Within trough lines, confirm width tier before quoting speed or total power
- Pre-cut vs post-cut is a configuration variant on the trough family — follow the agreed flow sheet
- Never mix perforated ~80 kW / 10–15 m/min forming references into a trough-only answer
5. Buyer FAQ
Is ladder tray the same as trough?
No. Ladder systems are a different product/process path. English “cable tray” wording alone does not move a trough soft model onto a ladder leaf.
Can one frame cover trough and perforated?
Do not assume it. Dense punching capacity and dual-arm forming on perforated lines are a different balance from trough pre-cut tables.
Which trough tier should I name?
Name the finished width band from the tray drawing (100–300, 100–600, or large 75–750 class) before asking for a single speed/power figure.
6. 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.
