Safe Landing Every 50 ft
Cage Ladder With Rest Platform – 50 ft Spacing
For tall climbs, a rest platform is more than comfort — it is compliance. We engineer safe landings at the correct spacing for your standard.
- OSHA: Every 50 ft
Landing platform within each 50 ft caged section (1910.28)
- EN ISO 14122-4: Rest Platforms
Rest platforms at roughly 6 m intervals for tall climbs
- Welded Steel
Platforms welded to match, HDG or SS304
| Specification | Value |
|---|---|
| Platform Spacing | Every 50 ft (OSHA caged section) |
| Rest Platform | ≥6 m intervals per EN ISO 14122-4 |
| Rung Diameter | Φ20 mm |
| Rung Spacing | 280 mm (≤300 mm) |
| Clear Width | 500 mm |
| Cage Diameter | Φ700 mm (hoops 40×5 @≤1500) |
| Top Exit Handrail | 1100 mm |

Ladder Cage and Platform – Custom Heights
Ladder Cage and Platform – Custom Heights
Tall structures need segmented climbs. We build custom heights to 25 m single run and beyond with rest platforms at the compliant spacing.
Custom Heights to 25 m Single Run
Single run to 25 m; taller climbs engineered as segmented runs with platforms.
Segmented Runs
Multi-run systems with rest platforms at compliant intervals for any total height.

When a Landing Platform Triggers — and How It Gets Sized
Fatigue, not height alone, drives the landing platform rule. A caged climb is safe at 12 m and exhausting at 12 m; the platform exists so a climber carrying tools can stop, stand upright and recover without leaving protected space. Regulators encode that intent with numbers. EN ISO 14122-4 introduces rest platforms on taller routes and expects them at roughly 6 m intervals; OSHA 1910.28 asks for landings at least every 50 ft of caged section. Whichever governs your site, the engineering logic is identical: split the climb into flights, terminate each cage at a platform, and restart the next flight from its deck.
| Sizing input | What it drives |
|---|---|
| Total rise | Flight count and platform positions |
| Climber load + tools | Deck and bracket sections, verified by calculation sheet |
| Route obstructions | Platform elevation shifts within the allowed interval |
| Exit style at top | Walk-through, side-step or plain rung continuation |
Guardrails rise to 1100 mm with toe boards at every edge, and each platform anchors through the same documented plan as the ladder itself. The free drawing review confirms spacing and sizing before a single plate is cut; platforms price at $150–400 within the one-kit quote.
Field Story — Port Conveyor Gallery, Valparaiso
Twenty-Two Meters of Climb, a Deck Every Flight
An EPC engineer describes the gallery access towers that replaced rope-and-harness maintenance along a shiploader conveyor. The build card is tower two.
Before — idlers serviced on a rope
The gallery runs 22 m at its tallest tower, and idler changes meant technicians on rope access over a working conveyor — slow, expensive, and dependent on a contractor's schedule. The port wanted its own crew on its own structure, and the marine air was eating the existing access steel faster than the paint program could follow. Any replacement had to make a 22 m climb something a technician in coveralls would do twice a day without ceremony.
During — flights, decks, and one kit per tower
We drew each tower as segmented flights with landing platforms inside the OSHA every-50-ft discipline: decks at 7.5, 15 and 22 m, each flight fully caged in its own right — cage from 2.2 m above every deck, hoops Φ700 at 1500, rungs Φ20 at 280 rated 1.5 kN. Landings sized for a climber with an idler roller to stand clear of the ladder line, guardrails at 1100 mm. HDG to ISO 1461 for the marine-coastal band with the coating report in the file, and each tower shipped as one kit — ladder, cages, platforms — trial-assembled and photographed before the crate closed.
After — rope access cancelled
The port's own crew took over idler work, and a change that used to be a two-contractor day became a morning with a toolbox. Decks double as staging points, so parts ride the tower in stages instead of hanging off belts. The insurer re-rated the access from contractor-rope to permanent-engineered on the strength of one compliance folder, and the rope-access retainer ended.
| Build Card — 22 m Gallery Tower | As Built | Why It Was Specified |
|---|---|---|
| Landings | decks at 7.5 / 15 / 22 m | inside the every-50-ft discipline with margin |
| Flights | each fully caged from 2.2 m above its deck | containment restarts — never interrupted |
| Deck size | climber + idler roller clear of ladder line | the landing is a workplace, not a pause |
| Finish | HDG 85–100 μm + report, ISO 1461 | marine-coastal life planned per ISO 14713 |
| Delivery | one kit per tower, trial-assembled | site bolting only — no field fabrication |
Tall Route, Three Answers
Landing-Platform Flights vs Single Tall Cage vs Gallery Stair
The port evaluated all three for its towers. The flights-with-landings design won on lifecycle — here is the comparison it won.
| Decision Factor | Flights + Landing Platforms | Single Tall Cage | Gallery Stair |
|---|---|---|---|
| Standards posture past 15 m | decks inside the every-50-ft rule | needs the rule satisfied elsewhere | outside ladder clauses |
| Climb reality at 20 m+ | three recoverable flights | one continuous, fatiguing effort | easiest, largest structure |
| Staging for parts and tools | decks are staging points | everything rides on the climber | treads carry anything |
| Steel and cost | platforms at $150–400 each as lines | least steel of the ladder options | several times either |
| Wind exposure on the structure | flights break the sail area | full-height cage acts as one panel | largest wind profile |
| Maintenance access economics | own crew, daily, no ceremony | fine for inspection-only routes | best cargo capacity |
- Choose flights with landing platforms when the route is tall and working — decks pay for themselves as staging the first month.
- Choose the single tall cage for inspection-only climbs to one top level where the platform rule is satisfied by the structure.
- Choose the gallery stair when cargo dominates and the port can afford the steel and the wind profile — rare, and priced accordingly.
Feature → Advantage → Your Outcome
What Landing Platforms Buy a Working Tall Route
Five lines from the gallery-tower drawing, translated into outcomes the port counted in season one.
| Feature | Advantage | Your Outcome |
|---|---|---|
| Landing inside every 50 ft | climb broken into legal flights | 22 m becomes a task, not an expedition |
| Deck sized for climber + parts | idler rollers stage at height | parts ride the tower, not the conveyor line |
| Guardrails at 1100 mm per deck | rest point is a guarded workplace | breathing space you can lean back into |
| One kit per tower, trial-assembled | interfaces proven at the factory | site work is bolts and torque, nothing else |
| HDG + coating report for marine air | zinc measured for the coast | repaint enters the plan on schedule, not by surprise |
