Hardware Anatomy
Inside a Self-Closing Swing Gate
A swing gate earns its reliability through five simple parts doing one job each — and through the discipline of how those parts are checked before they leave the plant. The anatomy table below names every component in the kit, what it contributes on the ladder, and the QC gate it must clear on the way out. Because the assembly is fully mechanical, site maintenance reduces to the periodic hinge-and-latch inspection covered in your site's regime, and any worn part can be reordered to original spec for the life of the ladder — our records run 10 years.
Leaves and brackets arrive hot-dip galvanized to ISO 1461 at 85–100 μm, welds inspected to ISO 5817 Level C, with SS304 and SS316 variants for corrosive sites.
| Component | Job on the Ladder | Checked At |
|---|---|---|
| Gate leaf | Closes the fall opening | Weld inspection, ISO 5817 Level C |
| Spring hinge pair | Returns the leaf after every pass | Trial assembly, closing action test |
| Latch catch | Holds the leaf shut until pushed | Engagement check at trial assembly |
| Mounting brackets | Bolt the gate to rails or posts | Sized to your rail section at order |
| Fixings set | Field bolts, no welding | Kit completeness at packing photo |
Swing Gate Part File — Codes, Springs, Service Triggers
The Self-Closing Leaf, Filed Part by Part for the Maintenance Plan
A swing gate is the most-ordered accessory we ship — simple, mechanical, and only as reliable as its return spring. Order by code, inspect the spring, and the gate outlives the argument for removing it.
| Ordering Code | Part | Spec | Ex-Works Band |
|---|---|---|---|
| DT-SW1-RH | Self-closing swing gate, right hand | Φ700 cage entry, spring return, HDG 85–100 μm | $60–180 |
| DT-SW1-LH | Self-closing swing gate, left hand | same build, mirrored leaf swing | $60–180 |
| DT-SW2-LK | Swing gate with lock option | cylinder lock on the self-closing leaf | upper band plus lock option |
| DT-SW3-SP | Return spring service set | replacement spring and hinge hardware | quoted per set |
| DT-SW4-SS | SS304 swing gate | corrosive-air build, same geometry | ≈ 1.8× the HDG price |
Service triggers for a self-closing leaf
- The release test, every inspection round — open the leaf fully and let go; anything slower than an immediate close-and-latch means the DT-SW3-SP service set goes on the next order
- Hinge play — grab the leaf at the latch side and rock it; visible lateral movement at the hinge line realigns the leaf poorly and wears the latch — order hinges with the spring set
- Latch strike alignment — if the leaf needs a shoulder nudge to latch, the strike plate has drifted; re-shim before the latch mechanism wears asymmetrically
- Spring zone corrosion — the spring works harder than the frame; check it at coating inspections and replace on first rust bloom rather than first failure
- Post-incident replacement — a leaf that has taken a vehicle strike or a dropped load is replaced, not straightened; steel that has yielded stays yielded
Fitting a Swing Gate to a Ladder You Already Own
Five Measurements That Confirm the Leaf Fits Your Cage
The swing gate is a retrofit part in most orders — it bolts to cages that have stood for years. Measure the five dimensions below, photograph the entry, and fit is confirmed in the 24-hour quote.
| Measure This | How | What It Decides |
|---|---|---|
| Cage inner diameter at entry | inside face to inside face across the hoop | gate width — standard builds target Φ700 mm cages, others made to measure |
| Hoop bar section | caliper the flat or bar at the opening | clamp pattern — our standard assumes 40×5 mm hoop flats |
| Opening height | bottom rail to top rail of the entry gap | leaf height and rail spacing |
| Swing side and arc clearance | stand at the entry and note which way the leaf must open, then check the arc for plant | right-hand or left-hand code, and whether the arc strikes anything |
| Rung spacing at the entry | center to center of the nearest rungs | bracket positions — standard 280 mm spacing needs no adapter |
Common retrofit mistakes
- Guessing the hand of the swing — a left-hand gate on a right-hand entry opens the leaf into the climber's path; one note on the order prevents the return shipment
- Measuring the hoop outside diameter — the gate clamps inside the cage; the inside dimension is the one that fits
- Ignoring the swing arc — a leaf that opens against a handrail or pipe jams half-open, which is worse than no gate; send a photo of the surroundings
Swing Gate Features, Climb Results
Five Things a Factory Swing Gate Does at the Cage Entry
The cheapest compliant upgrade on most sites — each feature below is the reason inspectors ask for this part by name.
| Feature | Advantage | Your Outcome |
|---|---|---|
| Spring-return leaf | closes itself, every user, every time | the entry is never left open behind a climber |
| Coded in both hands, $60–180 | right- and left-hand builds priced openly | reorder is a code, fitting is a maybe-one-hour job |
| Serviceable spring set | DT-SW3-SP replaces wear parts alone | the gate is maintained, not replaced, for years |
| Bolt-on clamp fitting | no welding on a standing cage | retrofit without hot-work permits or downtime |
| HDG 85–100 μm per ISO 1461 | zinc over leaf, frame and hardware | the gate weathers at the ladder's pace |
