EN ISO 14122-4 Quick Card — the Rule Numbers as Build Lines
Three Numbers Govern the Drawing — Here Is Each One on the Product
A standard becomes useful the moment it turns into steel. The quick card below maps the three governing figures of EN ISO 14122-4 onto the exact factory build lines they produce on your quote.
| Rule Figure | What the Standard Wants | Factory Build Line |
|---|---|---|
| Cage above 3 m | enclosure begins where the climb becomes dangerous | we build cages from 2.2 m — inside the EN figure and OSHA's band simultaneously |
| System to 10 m | single flights capped; longer climbs become multi-run systems | spliced sections with rest platforms, single pieces to 14 m for container loading |
| Platforms at 6 m | rest intervals on extended systems | bolt-on platform modules at $150–400, hole-matched at the factory |
| Rung and cage geometry | dimensional limits for safe climbing | rungs Φ20 at 280 mm, width 500 mm, cage Φ700 with hoops 40×5 and straps 30×3 |
| Evidence | conformity demonstrable | DoC naming EN ISO 14122-4, MTC 3.1, ISO 5817 C welds, per unit |
Reading the card as a buyer
- The 2.2 m cage start is deliberate — it satisfies the EN 3 m figure from below and keeps one build compliant across the Atlantic too
- Platform lines belong at drawing stage — a $150–400 module planned in arrives hole-matched; the same module discovered at review costs a survey
- Evidence is a deliverable, not a promise — every rule figure above has a document behind it that ships with the unit
Four Regimes, One Table
EN ISO 14122-4 Against OSHA, AS 1657 and BS 4211 — and the Build That Satisfies All
Multinational sites answer to several rulebooks at once. The table aligns the four regimes we quote against most, then states the single build geometry that clears them together.
| Regime | Home Reading | Cage Logic |
|---|---|---|
| EN ISO 14122-4 | EU single market, CE framework | cage above 3 m, systems to 10 m, platforms at 6 m |
| OSHA 1910.23 / 1910.28 | US workplaces | cages or fall arrest over 24 ft, phase dates from 2018 to 2036 |
| AS 1657 | Australia | cage above 3 m on fixed platforms and plant |
| BS 4211 | UK-linked projects | British code for fixed ladders, quoted alongside the EN file on request |
The one build that clears the table
- Cage from 2.2 m — earlier than the strictest 3 m figure, inside the OSHA band, one geometry everywhere
- DoC names the regimes you face — EN ISO 14122-4 as standard, OSHA when the operator audits to it, BS 4211 on UK-linked files
- When regimes conflict — specify to the strictest column and the others follow; we hold the drawing to that rule on request
The Standard as a Product
Five Things Buying EN ISO 14122-4 as a Factory Product Gets You
You are not buying a ladder and hoping it meets the code — the code is the product. Each row is what that framing delivers.
| Feature | Advantage | Your Outcome |
|---|---|---|
| Rule figures as build lines | 3 m, 6 m and 10 m mapped to parts on the quote | the drawing review checks boxes you already ticked |
| DoC naming EN ISO 14122-4 per unit | conformity declared, not discussed | CE-framework files close without vendor chases |
| Cross-regime geometry | cage from 2.2 m clears EN, OSHA and AS readings | one build serves every site your company owns |
| Free spec review before you commit | our engineer checks your climb against the standard | compliance questions answered before the PO, not after |
| Evidence chain with the crate | MTC 3.1, ISO 5817 C welds, trial-assembly photos | every clause of the file has a document behind it |
