Hanging-Type Multi-Profile Scaffold Plank Lines Explained

1. Definition

A hanging-type (hoist-change) scaffold plank line forms walking boards with one or more complete forming frames that can be lifted and swapped. The buyer promise is multi-profile production without re-gapping an entire fixed roller train stand by stand.

Contract English sometimes says “metal floor decking” while the BOM is hanging walking board / настил — keep it in the scaffold-plank equipment group, not structural floor decking.

2. Process and changeover

1. Manual ~5 t decoil
2. Level
3. Servo feed
4. Press punch (holes / logo / connection as drawn)
5. Hydraulic punch of head/tail notches
6. Hang-swap forming host (A/B sets)
7. Reshape → cut → exit

Industry “cassette / quick-change” plank explainers sell the same idea: whole tooling rafts for several board sizes. That is market context for changeover intent — not a license to copy their stand counts or kW onto this proposal.

3. Reference parameters

Do not publish one locked speed. Hold CN 8–12 and RU 5 side by side until the named proposal wins.

4. Boundaries and conflicts

• Not the fixed C225 single-family sheet (~5–10 m/min, ~22 / 5.5 kW).
• Not the GY160 punched + tracking package (~1–6 m/min, total ~45 kW).
• Not structural floor-deck equipment despite some English filenames.
• Brand lists (Yaskawa vs Siemens) are proposal-dependent — never merge into one “standard brand set.”

5. When buyers choose hanging

Choose hanging / hoist-change when the plant must run several walking-board profiles in the same shop and changeover time matters more than a single fixed roller set. Dual hanging hosts (A/B) cover two roller families; some projects add a third board shape across two machines.

6. Buyer FAQ

Why not just use spacers on a C225 machine?

Spacers help height or limited width variants on a fixed family. Whole hanging frames are for deeper multi-profile swaps where roller geometry differs more than a spacer kit can absorb.

Which speed should appear on the datasheet?

Name the proposal. CN with in-line punch cites about 8–12 m/min; some RU contracts cite about 5 m/min with punching. Publishing one number without the source sheet is incorrect.

Is “floor decking machine” the wrong leaf?

If the BOM is hanging walking board tooling, keep scaffold-plank classification. Structural floor deck is a different product and machine group.

What utilities and options often appear?

Two hanging formers, hydraulic notch dies, hydraulic shear, exit table; RU sheets may add marking options. Confirm against drawings.
