Cable carriers are designed to protect hoses and cables on moving machines. Cables are often exposed to challenging environments when the machinery or parts of it are moving. In some manufacturing environments, the heat may be too intense, and the water, steam, dust, equipment vibration, and other pollutants from the manufacturing process could damage the cables.
Using cable carriers makes it easy to extend the service life of the cables and machine, regardless of the constant repetitive motion. But how can one choose the best cable carriers for their applications? This piece highlights key factors to consider when selecting cable carriers.
Cable Features
While cable carriers may be made from standard components, users cannot just choose any type from a catalog and assume that they have found the right one for their application. The physical configuration and service conditions of each application usually need engineering analysis to pick the right carrier. The best cable and hose carriers are made of parallel side links that are joined by crossbars to support the hoses. The stops and pivot pins let the links travel via a predetermined arc.
Carriers can be made of metal or non-metallic links. Certain link-type designs may be enclosed completely to offer more protection for the hoses and cables. Users may also come across designs that open between links. Others are made of metal and come in a conduit-type design that is enclosed but made of convolutions rather than links.
Open, non-metallic carriers with links are a better choice in a situation where long travel and high speeds are factors. Such carriers are made of heavy-duty nylon reinforced with fiber, making them corrosion-resistant and non-conductive. Their standard uses include industrial robots and machine tools. It’s also possible to find lighter designs that are ideal for quiet operation applications and light automation machinery. These carriers come in a wide array of sizes to accommodate different applications.
The Environment
Environmental conditions of the machine application determine the kind of cable carrier to use. If the cables will be exposed to debris like metal shards or woodchips, or the machine works in a contaminated or dirty area, users should choose an enclosed tube.
Open crossbar cable carriers tend to be lightweight, which makes it easier to inspect and replace the cables. It is also essential for users to consider whether the application is underwater or likely to come in contact with any form of liquid.
Buyers should pick a barrier that can resist chemicals and corrosion. Exposing the cables to water or chemicals could lead to electrical issues or premature damage. Therefore, this is a critical consideration that could potentially prevent accidents and minimize repair costs.
Bend Radius
Generally, cable carriers have a programmed radius stopping point on every link. Once several links are assembled, the stopping points restrict the carrier from pivoting fully, forming a curved loop or minimum bend radius.
Cable carriers have several bend radii, and manufacturers usually recommend the minimum bend radius for each application. The larger the radius, the less strain is placed on a cable. This will make it easier for the cable to last longer.
Since the process of choosing a cable carrier may be complicated, users should consider consulting experts first. Experienced professionals can easily offer suggestions depending on the application parameters and requirements. Choosing the right cable carrier ensures the cables last longer and prevents expensive repairs or maintenance.
