Things To Remember When Designing A Cable Carrier System
DESIGN CONSIDERATIONS - Section 9
1. In vertical operating applications (versus horizontal), hanging the loop downward lets gravity work in harmony with the carrier system design, not against it.

2. When the operating height is restricted or with circular systems, the carrier system can operate placed on its side, using integral, snapped or bolted-on glide shoes, casters, or rollers.

3. As the carrier system travels back and forth between the extended and retracted positions (cycling), an adequate space that is free and clear of all obstructions must be provided for the carrier system to operate correctly and safely. (Equal to 110% of the carrier system's overall operating length x 105% overall width x 110% overall operating height).

4. If possible, avoid placing 3 or more similar and/or different cables or hoses into one cavity compartment.

5. Maximum recommended cable and hose carrier cavity fill is 60%.

6. Do not place cables and/or hoses of different sizes or types (e.g. flat or round) in one cavity compartment without vertical dividers or horizontal shelving between each.

7. Always place and/or separate cables and hoses inside the carrier cavity so they move independently and freely of each other.

8. Always use cables and hoses that are recommended for continuous flexing operation by their manufacturer.
9. Caution should be exercised when using cables with more than 25 conductors. Shifting of the conductors within the cable itself during machine operation can lead to cable failure.
10. Always individually clamp down cables and hoses at each end of the carrier system, once the carrier system is installed on the machinery, to prevent them from “walking” into or out of the carrier system during operation. KabelSchlepp’s patented cable clamps and/or product specific strain relief clamping brackets should be used.

wrong: cable’s bend radius is larger than the carrier’s forcing the cable to push against outside radius of carrier cavity
11. Never tie-wrap or fasten cables or hoses onto carrier system links or cross bars.
12. Check that all cables and hoses are not installed too tight (stretched between carrier bars) or too loose (hanging on the carrier bars) inside the carrier system when clamping them into place. Optimally, aim for the “neutral axis” (center line of the link) of the carrier system.
right: cable’s bend radius is less than or equal to the carrier’s allowing cable to lay comfortably in the carrier cavity
13. Refrain from using carrier system support rollers on medium to high speed, continuous duty cycle applications. Instead use a KabelSchlepp designed and built rolling-carriage system or gliding systems operating in a properly designed KabelSchlepp guide channel.
14. Carrier systems may become unstable when the inner cavity width ( Bi ) is less than 2x the inner cavity height ( hi ). Especially when the bend radius ( KR ) selected is greater than 3x the link height.
