Why a Box Panel Machine Uses Dual A/B Hosts

1. Short answer

Two box shapes, one line, hoist swap. A box-panel hoist-change line carries two forming hosts in one roll system. Host A and host B hold different roller sets for two enclosed box-panel profiles. A hoist swaps which host is in the run path when the plant changes product — avoiding a second full box line.

Industry multi-profile practice (cassette / tooling swap between panel shapes) is analogous context for changeover economics; ZTRFM box-panel evidence specifically names A/B hoist-change hosts, not generic auto-width alone.

2. Host contrast (reference)

• Finished width about 350–500 mm; thickness about 0.6–0.8 mm (per profile drawing)
• Speed about 12–15 m/min; main motor about 7.5 kW; hydraulic about 5.5 kW
• Structure: wall-panel frame; split tracks; single-side manual width trim within a profile family

3. Shared upstream path

1. 5 t passive loading
2. Guide infeed
3. Two-roll convey with optional protective film
4. Optional front cut
5. Punch side notches + holes
6. Roll form on host A or B (hoist-change)
7. Cut-to-length + flange both ends
8. Exit table

4. When flat deck panel is enough

Adjustable flat shelf decks without enclosed box sections use a single-host deck-panel line (reference ~30 stands / ~11 kW) — different equipment path. Do not mix deck-panel stand counts or power into a box-panel quote.

5. Inquiry checklist

• A and B profile drawings (geometry, width, thickness)
• Hoist changeover procedure and downtime expectation
• Notch / hole punch drawings shared by both hosts
• Whether film coating or front cut is required

6. Buyer FAQ

Is this the same as box beam?

No. Box beam is a rack horizontal (C + seam). This page is shelf box panel with dual forming hosts.

Can both hosts run at once?

No — one active host after hoist changeover. The idle host stays offline until the next profile change.

Why different stand counts (24 vs 14)?

Each host carries the roller set for one box geometry. Pass count follows the profile — do not average A and B into one “typical stands” number.

Is split-track trim the same as hoist change?

No. Split-track trim adjusts width within a profile family. Hoist change swaps the entire forming host between two box shapes.
