CARBON FOLDING GANGWAYS

Designed for one person to handle and deploy with ease. Our folding carbon gangways are even easier to stow aboard. With a maximum load capacity of 350 kg, they are still extremely light (starting from 3.5 kg). At 600 mm wide, the bigger model is also 50% wider than most comparable products, making for a safe, comfortable crossing from ship to shore.

Key  Features

• 100% carbon fibre pre-preg fabrics

• autoclave curing (120° C / 7 bar)

• unidirectional carbon fibre integral hinges

• UV resistant epoxy resin with transparent anti UV coating

• hard anodised CNC machined light alloy hardware

PATENTED CONTINUOUS SHELL CONSTRUCTION (PCT/IT2005/000315)

The wheels are CE certified and built in one piece, becoming an immensely strong monocoque structure: no weak joints nor secondary bondings. The three spoke design leaves a clear view of the instruments. 

The wheels are supplied with the suitable hub for any steering brand, built with aluminium alloy and protected with hard anodising against corrosion and wear.

Key  Features

• 100% carbon fibre pre-preg fabrics

• autoclave curing (120° C / 7 bar)

• UV resistant epoxy resin with transparent anti UV coating

• high gloss carbon fibre finish as standard

• custom painting on request

 Our carbon steering wheels are entirely made in Italy

WHY HAVE A CARBON FIBER WHEEL?

• The massive reduction in weight results in much lower rotational inertia making for a much more responsive helm.

• The power drain on the auto-pilot system becomes considerably lower too.

• Compared with light alloy fabricated wheels, which are easily bent, these carbon fibre wheels are incredibly strong.

• The big outer section rim provides a more comfortable grip for the helm.

•  It is wear resistant. 

THE ORIGINS OF A CONSTRUCTION – THE REASONS FOR A DESIGN

                                                                                   Y or I? Two solutions for a problem                              see the loads scheme

The question: Transfer the thrust from the rim to the spokes to discharge it onto the axle

It is a simple question but with numerous different solutions. If the thrust is in front of a spoke, the main load is exclusively flexion, but if the thrust is intermediate between two spokes, the flexion lowers as the number of spokes decreases and, as the figures shows in case D to A, it mainly becomes torsion. If we just want to use a few spokes, they must be designed to resist two types of load and they must have a very wide connection to the rim to do this. Just think of what happens if you try to unscrew a screw with a screwdriver that is too small.

As we can see the Y construction behaves like metal wheels with a lot of spokes.

The reasons why Exit Engineering have adopted the current 3-spoke construction, despite the greater structural complexity, are numerous and in our opinion fully justify the greater design work involved:

• A few larger diameter spokes require a rolling process that is very easy to control, meaning that the quality and reliability of the wheels is uniform;

• A few spokes without any forks reduce to a minimum the number of carbon plies, reducing the overlap between adjacent plies, because, in a carbon wheel, the overlaps account for a significant part of the overall weight;

• The simplified internal vacuum bags means that our patented Continuous Shell system can be used, to make a monocoque wheel without any gluing work;

• The wide connections to the rim reduce tension peaks, meaning that minimum thickness can be used away from the hub, to the benefit of low rotational inertia.

Therefore we consider that the construction with a few spokes without any Y forks is superior, but attention must be paid to how the spokes are connected to the rim and hub. A good project should have wide connections to both.
The alternatives are excessive weight and/or potentially fragile interface.
