Cable bridge
A cable bridge , also known as a floor duct or floor duct , is a tread-resistant profile made of plastic that covers, guides and fixes the cable lying loosely on the floor . The cables are neatly routed through vertical dividers. As part of an electrical installation, the cable bridge represents a special design of a cable duct and is related to the hose bridge in terms of its function and mode of operation .
Basic problem
Cables that run unsecured on the floor are not only an aesthetic impairment, which is also referred to as cable clutter , but also represent a safety risk. On the one hand, there is the risk that the cables and the devices connected to them will be damaged. On the other hand, unsecured cables are dangerous stumbling blocks that often lead to accidents with personal injury.
Troubleshooting
Cable bridges fix the cables in ducts and thus protect them from stresses caused by crushing, tension, abrasion and weather-related damage. Bundling eliminates the risk of people becoming entangled in loosely lying cables and falling as a result. Suitable products lie flat on the substrate, are gently bevelled, clearly recognizable and easy to install.
Types
Outdoor use
Cable bridges of this type must protect cables even in extreme situations and are therefore heavily stressed, e.g. B. on construction sites or at outdoor events (see also hose bridges ). Especially at events, cable bridges are often used as run-over protection and to protect visitors from electrostatic discharge. The cable bridge represents a non-conductive boundary between people and power cables. They often consist of rigid individual segments that are strung together as required. They are often made of aluminum, hard plastic or rubber. Improvised solutions made of wood are also often used.
Indoor use
For cable bridges that are used in rooms, protection against tripping accidents is usually the main focus. Cable bridges of this type are often made of rigid PVC or metal. During installation, they are connected to the subsurface. (Screw or adhesive connection). In addition, there are flexible systems that do not have to be fixed to the ground. Thanks to a special composite material (high dead weight) and a suitable shape, they lie snugly on the ground, flexibly follow uneven floors and therefore do not slip.
Equipment options
From above
Cable bridges, which are covered with cables from above, are in two parts. They consist of a base with cable ducts into which the cables and lines are inserted. The cable bridge is closed with the corresponding cover and the cables are protected in it. The lid can be made of flexible plastic or sturdy aluminum. This type of cable bridge is easy to use and is especially chosen for flexible applications.
From underneath
Cable bridges that are fitted from below are one-piece. The cables are inserted into the cable slots provided on the underside of the cable duct. This type of cable bridges are used for a longer period of time, since the constant assembly and dismantling of the cable protection is rather tedious.
Legal basis, ordinances, recommendations
- § 3 (1) ArbStättV / Appendix; Point 1.5 (2):
- “The floors of the rooms must not have any unevenness, holes, tripping points or dangerous slopes. They have to be secured against slipping, stable, sure-footed and slip-resistant. "

- "Cable bridges must be used for cabling over traffic routes in order to reduce the risk of tripping."
