Safe Cat Ladder Access · Fall Protection Configurations

Cat Ladder Safety Solutions for Roofs & Plants

Factory cat ladders built safe-first: OSHA and EN ISO cage geometry, continuous fall-arrest rails, self-closing gates and rest platforms. Every configuration is fabricated in the same Dengtai factory as our standard ladders, so stiles, rungs and protection always line up. An access route that fails inspection means stop-work orders and retrofit scaffolding at site rates.

What safe cat ladder access includes

Four layers of cat ladder safety, bolted together

Safety cage & hoops
Hoop spacing and depth per OSHA 1910.28 and EN ISO 14122-4, welded to the same Q235B or stainless stiles.
Vertical fall-arrest rail
Continuous rail with a sliding sleeve so the climber keeps both hands on the rungs, with automatic locking.
Self-closing safety gate
Bolt-on gate at landings and platforms to close the fall opening when the ladder is not in use.
Rest platforms
Every 6 m of run per EN ISO 14122-4; our max single segment is 25 m, taller runs are split with platforms.

Safety Cage

Cage hoops, vertical bars and fixings in grade-matched steel. SS304 bolts as standard, HDG or stainless to match the ladder.

Fall-Arrest Rail

Continuous vertical rail + sliding sleeve that locks on fall. Meets ladder safety system duty on ladders over 24 ft (7.3 m).

Safety Gate

Self-closing landing gate that swings shut automatically, closing the access opening when the ladder is not in use.

Rest Platform

Galvanised or stainless rest platform and guardrail, bolted at 6 m intervals to break long climbs and taller runs.

Cat Ladder Safety Requirements, Standard by Standard

Cat ladder safety requirements vary by country and climb height. This snapshot shows the common thresholds under the standards we build to — your engineer-signed structural calc sheet confirms the exact arrangement for your site.

Rung spacing	254–356 mm (10–14 in) uniform	225–300 mm uniform	225–300 mm
Rung load	1.5 kN single rung point load	1.5 kN single rung point load	1.5 kN single rung point load
Fixing centres (our build standard)	≤1500 mm	≤1500 mm	≤1500 mm

How we confirm compliance

Requirements met at the drawing stage, not on site

Free drawing review
Send your height, mounting surface and country — our engineers confirm the cat ladder safety requirements and mark up the layout within 24 hours.
Engineer-signed calcs
A structural calculation sheet is produced for your exact configuration and fixing layout, signed by a Dengtai engineer.
No rework on site
Cage hoops, rails and gates are trial-assembled and jig-checked before galvanising — nothing to correct after delivery.

Cat Ladder Safety FAQ

What cat ladder safety requirements apply to my roof access?

Cat ladder safety requirements depend on your country and climb height. Dengtai fabricates to OSHA 1910.28 / 1910.23, EN ISO 14122-4, BS 4211 and AS 1657 — 1.5 kN rung load, 225–230 mm rung spacing, fixings at ≤1500 mm centres, rest platforms on runs over 6 m and fall protection above 3 m of climb under EN ISO 14122-4 (24 ft / 7.3 m under OSHA). Your engineer-signed structural calculation sheet confirms the exact arrangement for your height.

At what height does a cat ladder need a safety cage or fall arrest?

Under OSHA 1910.28, fixed ladders taller than 24 ft (7.3 m) above a lower level need a personal fall arrest system or ladder safety system on new installations, while legacy ladders may keep cages. EN ISO 14122-4 requires rest platforms on runs above 6 m and fall protection on climbs above 3 m. Tell us your height in the RFQ and we specify the right cage, fall arrest rail or safety gate in the free drawing review.

What cat ladder safety regulations do your ladders meet?

Every ladder is fabricated to OSHA 1910.28 / 1910.23, EN ISO 14122-4, BS 4211 and AS 1657 as applicable, and ships with a Declaration of Conformity, an MTC 3.1 material certificate and engineer-signed structural calculation sheets — all at no extra cost.

Can I add fall protection to an existing cat ladder?

Yes — retrofit safety cages, vertical fall-arrest rails and self-closing safety gates are fabricated to bolt onto your existing stile spacing. Send a photo of the ladder and we confirm the right cat ladder safety upgrade within 24 hours.

How long does a safe cat ladder configuration take to deliver?

A quote lands in 24 hours and production runs 15–25 working days from the approved drawing. Shipping goes EXW, FOB or CIF, so cages, rails and gates arrive together with the ladder they protect — and the compliance file travels in the same crate.

Can we order one safety-upgraded ladder first?

Yes — trial orders start from 1 unit, so you can audit one roof access before rolling out. Larger programmes use container mixes quoted per load plan, combining caged ladders, fall-arrest rails and self-closing gates in single shipments, each with its own order-level compliance file.

What payment terms apply to cat ladder safety orders?

Standard terms are T/T with a 30% deposit and 70% against the B/L copy. Alternatives are confirmed in writing on the proforma invoice before production begins, so the commercial terms are as clear as the safety documentation that follows the order.

What documents will a safety auditor ask for?

The order-level file: a Declaration of Conformity, the EN 10204 3.1 MTC, an HDG coating report to ISO 1461 and engineer-signed structural calcs, free with every order. Because they are issued per order, each paper matches the installed ladder, not a generic product line.

Which is safer on a tall climb — a cage or a fall-arrest rail?

Both are accepted engineered answers, chosen by standard and height. EN ISO 14122-4 requires fall protection on climbs above 3 m, while OSHA 1910.28(b)(9) requires a ladder safety system or PFAS on new installations over 24 ft. We engineer either option — with rungs rated at 1.5 kN — and confirm the right one in the free drawing review.
