Cassette Quick-Change vs Manual Roll Change on Strut Lines

1. What changes for the buyer

Manual spacer / roll change (41-series page) keeps rolls on the host and rebuilds sections with spacers or roll swaps. Cassette quick-change parks tooling in boxed cassettes (~22 stands + cog per box) so operators exchange boxes instead of a full rebuild.

Both serve 41-family strut / C-channel work. They are different mechanical packages — do not merge speed or kW tables.

2. Cassette reference tier (quick-change page)

3. Manual 41-series notes (do not overwrite cassette)

Also keep TJ20 (~55 kW, ~0–20) and seismic multi-tier packages off this comparison’s unique numbers.

4. When cassette is usually preferred

• Frequent turnover among a small set of 41-family sections
• Operators trained on cassette lift/lock rather than long spacer rebuilds
• Proposal already budgets spare cassettes and punch tooling for each section

5. Buyer FAQ

Does cassette always mean faster line speed?

Not automatically. Cassette reference forming is about 0–15 m/min; some manual making docs cite about 25 m/min — changeover time and meter speed are different questions.

Can I quote TJ20 55 kW on a cassette RFQ?

No.

Is cassette a different product line from strut?

It stays in the strut channel family; the difference is the changeover structure and its own rating table.

6. Verification notes

• Publish only numbers that appear on the named FAQ / parameter sheet for this leaf.
• When two source documents disagree, list both tiers with labels — do not average.
• Host ratings stay separate from auxiliaries (curving, stacking, offline presses) unless the FAQ bundles them.
• Directory identity is fixed; open fields stay blocked until a proposal confirms them.
