Lyon Flexible Sided Ladders
Flexible Sided Ladders have rigid rungs and flexible sides - normally made from polyester or wire rope. This allows suspension from a fixed point rather than leaned against a structure and also allows the ladder to be rolled for transport or storage - they weigh much less than a rigid sided ladder of similar length and can be used in confined locations where conventional ladders could not be deployed. Originally developed for cavers, Lyon Flexible Sided Ladders are now widely used in:
-Confined space silo access
-Manhole and sewer access
And many other applications.
For more detailed information on our ladder range and options click the headings below or download our full flexible sided ladder brochure.
Aluminium alloy - plain : Used on regular and lightweight ladders. Available in 2 diameters - 12.5mm (Compact and Speleo ladders only) and 25mm (Wide Rung only).
Aluminium alloy - black anodised : For low visibility in military, security or theatrical applications. The additional protection from corrosion given by the anodising process makes these rungs more suitable for use in corrosive environments. Available in 2 diameters - 12.5mm (Compact ladders only) and 25mm (Wide Rung only).
High grip knurled : Knurled finish for extra grip (Compact ladder only)
High grip 34mm fluted GRP : Chunky rings which are easier to grip. GRP rungs also have the advantage that they are least likely to scratch any surface they contact.
Galvanised steel wire rope : Used on regular ladders (4mm) and lightweight ladders (3mm), ideal for high strength and durability.
Stainless steel wire rope : Where a corrosive atmosphere might reduce the life span of galvanised wire rope.
Polyester rope : 8mm rope for use on Wide Rung GRP ladders only. May be suitable for environments where electric shock is a risk.
General purpose ladders, for applications such as manhole entry, access to lighting truss and sport caving. Made from aluminium alloy rungs and flexible wire rope sides, Compact ladders are 150mm wide (wide enough for one foot) and are ideal when you need to keep weight down without reducing loading capacity. Compact ladders come in three versions:
Compact Regular – the most popular style – durable and versatile. Recommended for frequent use. Uses 4mm wire.
Compact Lightweight – for situations where weight is more important than durability. Only recommended for infrequent use. Uses 3mm wire.
Compact Speleo - designed for cavers where a ladder with simplified c-link joining is preferred.
And with three rung options:
Plain alloy rung – self-coloured alloy rung.The standard for most applications.
Black anodised rung – fitted on stainless steel wire rope sides – for where corrosion is a risk i.e. marine environments. Also useful for theatres and military applications where a less bright finish is required. (Regular ladder only)
Black High grip rung – as above, but with a knurled finish for better grip. (Regular ladder only)
Key Compact features:
-Compact design allows easy storage and transport
-Available in three versions
-Available with three different rung options
-Choice of two rung spacings – 25 or 30cm
-5 or 10 metres standard lengths
-Lengths of up to 20 metres to special order • Easily joined together if necessary
Wide Rung Ladders
Easy to handle ladders, for applications such as silo access for inspection and cleaning and for use over sloping structures (such as vessels). Wide Rung ladders are made from either aluminium alloy or glass reinforced plastic (GRP) rungs with flexible wire or textile rope sides, Wide Rung ladders are 270mm wide allowing the climber to place both feet on one rung.
Wide Rung ladders are only manufactured in one version:
Regular - This specification is durable and versatile, ideal for the intended use.
Wide Rung ladders are available with four rung options:
Plain alloy rung – self-coloured alloy rung, the standard for most applications.
Black anodised rung – fitted on stainless steel wire rope sides – for where corrosion is a risk i.e. marine environments. Also useful for theatres and military applications where a less bright finish is required.
GRP rung with wire sides – Glass reinforced plastic rungs with stainless steel wire rope sides – easy to clean, used by the food and pharmaceutical industries.
GRP rung with rope sides – Glass reinforced plastic rungs with polyester rope sides – may be more suitable where electric shock is a potential hazard. Heavily fluted rungs are easier to grip, so this ladder is better for muddy / slippery environments
Key Wide Rung features:
-Wide enough to fit both feet side by side
-Large diameter rungs are more easy to handle and more comfortable to stand on
-Easy clean materials options
-Available with four different rung options
-Choice of two rung spacings – 25 or 30cm
-Made to order in lengths of up to 15 metres
Wide enough for a single foot, these specialist ladders are lightweight, and make virtually no noise when deployed. They are an alternative to wire sided or wooden rope ladders. Constructed from textile sides and carbon fibre rungs they are ideally suited to wet environments.
Joining Fibrelight Ladders - Standard Fibrelight ladders are supplied with a single anchor point and Maillon Rapide at the head making them unsuitable for connection to increase the length. Fibrelight ladders are always made to customers specified lengths. If you require Fibrelight ladders which can be joined, please contact us.
-Easy to rig.
-Compact for easy storage.
-Non metallic ladder –no parts to corrode.
-Complete with bag and stainless steel connector.
-Lighter than our Compact or Wide Rung ladders.
-Can be ordered by the metre (up to 20 metres).
-30 cm rung spacing.
-Black, yellow and red tape available.
NOTE: For lightweight use only. For heavy and / or regular use, we recommend our Compact or Wide Rung ladders.
We usually make ladders of either 5m or 10m lengths but can make longer on request. If ladders will be de-rigged for transport or storage, or if there is a risk of damage, it is usually better to join several shorter lengths rather than use one continuous unit. By selecting one of the connecting options it is possible to make a continuous ladder with even rung spacing across the joints.
Connection Options -If two or more ladders are to be joined, use of one of the following connection methods will ensure that spacing between rungs is consistent across the join.
Swaged eyelets only - Unless specified, ladders will be supplied with a swaged eyelet on the end of each side wire. They can then be connected with a removable Maillon Rapide.
Swaged eyelets and fixed c-links - Only fitted to Speleo Ladders, permanently fixed to the ladder during manufacture to prevent loss.
-Easy to connect together, even with cold wet hands
-Lightweight for sport caving use only
-For use on Speleo ladders only
Eyelet Maillon Rapides - Lightweight screw-link connectors with high strength. Permanently fixed to the ladder during manufacture to prevent loss. Request at the time of ordering as these cannot be fitted after manufacture. Ideal for industrial use, can be used on many types of anchor
NOTE: Eyelet Maillon Rapides are only available in galvanised steel and are not suitable for ladders with stainless steel wire or rope sides.
Ladder Spreader -If a ladder will be fixed to a single point, a Ladder Spreader should be used. Ladder Spreaders are available in 4 different types to match ladder connection types.
Ladder Belay - Can be used to achieve a suitable anchor when wrapped around fixed structures. Available in swaged eyelet ends or with c-links for Speleo Ladders.
Storage & Rapid Deployment Pouch - Allows ladders to be stored at the point of use ready for immediate deployment.
Stand Off's - Suitable for GRP fluted rung ladders only, this item keeps ladders away from a wall allowing easier climbing. A pair of stand offs is applied to every third rung of the ladder for vertical hangs. More maybe required if the ladder rests on an inclined/curved surface.
