Cable Carrier Design Considerations

Selecting a Carrier: Beginning with the Cable/Hose Package

When choosing a carrier, the first thing to do is to make a list of all cables, hoses, and wires that must be placed inside. Sizing begins by determining the outer diameter of the largest cable or hose, and then adding a clearance factor (10% for cables, 20% for hoses) to arrive at a minimum cavity height. The next step is to add the same clearance factors to the remaining cables and hoses to come up with a minimum cavity width. Don't forget to allow for vertical separators - ideally all cables and hoses are separate or unable to cross over each other in inside the carrier, which can lead to tangling and premature wear.  (read more: How to Size Your Carrier)

These first two steps will allow you to preselect some carrier sizes, but there are many other considerations such as the minimum bend radius of the cable or hose, the operating conditions, and the environment. To save time, use our guided questionnaire (see our Quote form) to provide all your application details and let Dynatect make the calculations and recommend a carrier based on your application.

Metal vs. Plastic Carriers

Dynatect offers both plastic and metal carriers and can recommend the ideal choice for your application.

Plastic carriers are usually the first choice in applications requiring higher speeds and accelerations and long travel. Modular plastic carriers can easily be customized with a large choice of modular components such as aluminum crossbars or armor plates.

Standard plastic carriers offer clean, light-weight designs that easily snap together to allow easy adjustment of length. Nylatube carriers offer the similar features but are fully enclosed.

In general, use Gortrac Steel Carriers with elevated operating temperatures or when heavy loads exceed the maximum unsupported travel of plastic carriers. Use Gortrac steel carriers with lower speeds; however, higher speeds have been achieved with control of acceleration and deceleration. 

Gortrac Steel Carriers have the highest strength-to-weight ratio and maximum unsupported span capability. Gortrac offers several lightweight steel carriers that are competitively priced with plastic, while providing significantly greater strength and unsupported spans than similar-sized plastic carriers.

Open-Style vs. Enclosed-Style Carriers

Dynatect provides both open and enclosed-style cable carrier options. Protective nylon cable/hose sleeves are also available for nearly any application.

Open-style carriers provide easy cable/hose inspection. For open-style carriers, see Nylatrac (standard & modular) Series and Gortrac Series carriers.

Enclosed-style carriers protect against sparks, shavings, and hot chips. For enclosed options, see:

► Nylatrac Modular carriers (TSC, TS, TL, & NXL Series) are available with plastic or metallic lids.

► Nylatube (KOE, N, KLE Series) carriers are enclosed plastic carriers.

► Gortube Series carriers are enclosed metallic conduit-style carriers.

► Gortrac Steel (SRC, LRC, XL Series) carriers are available enclosed with optional aluminum armor plates.
