Perforated Tray-Type Cable Tray Roll Forming Line

1. Definition

A perforated / tray-type cable tray line cold-forms ventilated tray sections: decoil → level → servo feed → punch (and often cut) on flat strip → powered guide → roll form → collect. Dense hole patterns for ventilation and mounting are punched before the U / tray section is formed.

It is not a solid-bottom trough line (narrow / mid / large width tiers), not a ladder-tray welding line, and not a generic catch-all for every cable-tray width family.

3. Line sequence

1. Single-arm hydraulic decoiler (about 8 t class)
2. Seven-roll leveler
3. Multi-stage servo feeding
4. Press punching and shear (combination dies)
5. Powered conveyance and guide
6. Dual-arm roll forming
7. Roller discharge

4. Boundary vs trough

• Do not paste trough English speeds ~3–6 or large-tier punch ~3–8 as this machine’s only numbers
• Do not paste trough total-power sheets (e.g. large ~77 / mid ~94.5 class) into this perforated package
• Heavier press punching and different speed balance (punch often slower than pure forming) define this type
• Connector plates are accessories, not this host

5. Inquiry checklist

• Tray profile drawing and hole map
• Width / height range and thickness
• Whether punch+shear combination dies are required
• Target punch vs forming speed class
• Voltage / frequency preferences

6. Buyer FAQ

Same machine as trough?

No — separate line family and BOM. Order by tray vs trough drawings.

Why are punch and forming speeds different?

Dense punching often sets the production cadence (~6–8 m/min) even when forming can run ~10–15 m/min. Quote both and say which limits output.

Can I use trough ~80 kW figures here?

No. Keep perforated ~80 kW class and motor grouping on this package; trough width tiers have their own sheets.

Is ladder tray included?

No. Ladder systems are a different product path (often welding-heavy). Confirm tray type on the inquiry.
