The Geometry Behind the Rating
Safety Ladder Cage Specifications — and Why Each Number Earns Its Place
Inspectors do not test numbers at random; every dimension below traces to a performance requirement. This is the dimensional DNA our cages carry into every drawing, weld and DoC.
| Specification | Value | Why It Matters |
|---|---|---|
| Cage barrel diameter | Φ700 mm | Contains the climber without trapping gear or elbows |
| Hoop section and pitch | 40×5 mm at 1500 mm | Rings stiff enough to take side load, light enough to bolt |
| Strap section | 30×3 mm verticals | Continuous wall between hoops for the torso |
| Cage start height | 2.2 m above floor | Protection begins where falls turn serious |
| Rung and width | Φ20 mm at 280 mm, 500 mm clear | 1.5 kN per rung with a comfortable climbing stance |
| Longest single piece | 14 m hot-dip galvanized | Transport and handling limit before splices are needed |
These values satisfy OSHA 1910.28 and EN ISO 14122-4 simultaneously, which is why one drawing set serves both markets. Ask for the spec sheet with your quote — every number above appears on it, traceable to the standard clause it serves.
Spec Before Price
Safety Ladder Cage — Buy Standard, Buy Custom, or Buy Twice?
The dimensional DNA above is our standard geometry — rung Φ20 at 280 mm, 500 mm clear width, Φ700 mm cage with hoops 40×5 at 1500 mm and straps 30×3. Standard DNA is the cheapest compliant ladder you can buy, because the fixtures, welds and calcs already exist. Custom height is not a customization premium; it is a cut-to-measure operation inside the same geometry. What actually costs money is changing the DNA itself — and most specs that do it, should not. The verdicts below keep your order on the cheap side of that line.
| Your Requirement | Order | Why It Is the Cheapest Route |
|---|---|---|
| Height fits a common band, any regime | Standard geometry at your exact cut | fixtures and calcs exist; only the cut length changes |
| Site height between catalog sizes | Cut-to-measure, same DNA | no premium for honest millimeters |
| US drawings under OSHA | Standard DNA, dual-dimensioned sheets | 500 mm width and Φ700 mm cage satisfy the clause set both sides of the ocean |
| Obstruction inside the cage swing | Custom hoop layout, engineered | the only custom worth paying for — geometry the site forces |
| Repeat of any prior order | Archive pull, 10-year records | quoted in hours at the identical geometry |
| The Spec-Drift Error | Its Price Tag | The Discipline |
|---|---|---|
| Custom rung spacing where 280 mm complies | re-engineering a dimension every standard accepts | keep Φ20 @ 280 — it clears every threshold with margin |
| Oversized cage diameter "for comfort" | more steel, new calcs, no compliance gained | Φ700 mm is the tested envelope; comfort is rung spacing |
| Imperial round-ups written into metric builds | mixed-unit drawings, mismatched anchor grids | dual-dimensioned sheets from us — one master geometry |
| Each site office speccing its own variant | ten part numbers for one ladder | one site standard; our spec sheet with every quote |
Feature to Outcome
Five Spec Discipline Lines That Show Up in Your Price
Each row is the procurement advantage of buying from the factory that set the geometry.
| Feature | Advantage | Your Outcome |
|---|---|---|
| One DNA across OSHA, EN, AS and BS sites | 500 mm width, Φ700 mm cage clears all four | one part number fleet-wide, one drawing to maintain |
| Cut-to-measure heights inside standard DNA | exact meters without engineering fees | no rounding up, no fill-in platforms |
| Spec sheet mapped clause by clause | every dimension traceable to its standard | review meetings end with the sheet, not a debate |
| 10-year archive of your exact build | geometry, calcs and QC photos retrievable | repeat orders quote in hours at identical DNA |
| 24 h quote, MOQ 1, 15–25 day build | trial before rollout at production quality | the rollout decision made on installed evidence |
