Component Engineering
Cage Component Blueprint
A ladder cage is a small family of parts working together, and every member of that family is dimensioned by the safety standards your site answers to. The blueprint below lists our standard cage geometry next to the thresholds that drive it: EN ISO 14122-4 calls for a cage above 3 m climb height with rest platforms at 6 m intervals and a ladder safety system above 10 m, AS 1657:2018 requires a cage above 3 m, and OSHA 1910.28 sets the 24 ft threshold — with the existing-cage exemption closing on 18 November 2036. Checking your hoop order against this table before quoting prevents the most common retrofit error: mixing strap sections from different cage generations.
All hoop assemblies are hot-dip galvanized to ISO 1461 at 85–100 μm as standard, with welds inspected to ISO 5817 Level C before galvanizing.
| Cage Component | Section | Position | Standard Ref |
|---|---|---|---|
| Hoop (basket ring) | 40×5 mm flat bar | 1500 mm vertical centers | EN ISO 14122-4 · OSHA 1910.28 |
| Vertical straps | 30×3 mm flat bar | Fixed between hoops | EN ISO 14122-4 |
| Cage bore | Φ700 mm | Concentric with climb | Matches 500 mm climb width |
| Cage start | 2.2 m from base | Bottom of first hoop | Dengtai standard build |
| Weld inspection | ISO 5817 Level C | Before galvanizing | Stage 2 of 5-stage QC |
Hoop and Strap Part File — Codes, Gauges, Service Triggers
Cage Components, Filed Part by Part for the Inspection Round
A cage is a family of repeatable parts — hoops at set centres, straps between them, fasteners through both. Order them by code and gauge, and the cage becomes a maintained system instead of a welded mystery.
| Ordering Code | Part | Spec | Pricing |
|---|---|---|---|
| DT-H1-700 | Cage hoop | 40×5 mm flat bar, rolled to Φ700 mm cage form | quoted per piece |
| DT-H2-ST | Cage strap | 30×3 mm strap, hooping between bars | quoted per piece |
| DT-H3-SC | Self-closing gate for the cage entry | companion part at the entry hoop | $60–180 |
| DT-H4-SS | SS304 hoop and strap set | corrosive-air build, same geometry | ≈ 1.8× the HDG price |
Service triggers for cage components
- Hoop alignment sight-down — sight along the cage from below; any hoop visibly out of plane has taken a load it should not have, and the fasteners at that hoop are inspected before the next climb
- Strap loss or deflection — a strap bent clear of the climber's path or missing entirely is replaced by code; straps are the cage's fall-containment surface, not decoration
- Fastener torque at coating inspections — hoop and strap bolts are the wearing interface; re-torque on the plant's scheduled rounds and replace any bolt showing thread corrosion
- Weld inspection on spliced hoops — hoop joints certified to ISO 5817 C at build; any cracked joint post-incident condemns the hoop, not the cage
- Zinc breach at drill holes — field-drilled holes bypass the ISO 1461 kettle; order hoops pre-drilled so every hole ships galvanized
Matching Hoops to the Cage You Already Have
Four Measurements That Confirm Hoop and Strap Fit
Whether you are extending a cage, replacing storm damage or converting an uncaged climb, the same four dimensions decide what ships. A tape, a caliper and one photo settle it.
| Measure This | How | What It Decides |
|---|---|---|
| Existing cage diameter | across existing hoops, outside edge to outside edge at the widest | new hoops roll to match — standard builds are Φ700 mm |
| Hoop spacing centers | center to center between two adjacent hoops | strap lengths and the 1500 mm standard — wider gaps need intermediate hoops |
| Stringer and rail sections | caliper the ladder's side rails where hoops attach | clamp bracket size and bolt pattern |
| Cage start height | floor to the lowest existing hoop or intended cage start | compliance position — our builds start the cage at 2.2 m to clear every major standard |
Common hoop-ordering mistakes
- Ordering hoops by climbing height — hoop count follows cage length and the 1500 mm centres, not the total climb; send the caged section length instead
- Field-drilling instead of pre-drilled ordering — every field hole is an ungalvanized corrosion starting point; order holes drilled at the factory before the kettle
- Mixing hoop gauges in one cage — 40×5 hoops carry the containment logic; lighter substitutes deform on the first lean and fail the inspection
Hoop Features, Containment Results
Five Things Factory Hoops and Straps Do for the Climb They Enclose
The cage is the protection; the hoops are the cage. Each row below states a factory feature and the containment result it purchases.
| Feature | Advantage | Your Outcome |
|---|---|---|
| 40×5 hoops rolled to Φ700 | containment geometry as engineered, not improvised | the cage performs on the day someone leans into it |
| 30×3 straps between hoops | fall surface continuous along the climb | no unguarded band anywhere above 2.2 m |
| Pre-drilled, kettle-dipped holes | every fastener hole galvanized at ISO 1461 | corrosion never starts at the bolt line |
| Coded parts quoted per piece | replace one hoop or a hundred by code | storm damage repairs in days, not drawing weeks |
| Welds certified to ISO 5817 C | hoop joints documented at build | the inspection answers come from the file |
