Cable and Hose Distribution Guidelines

Dynatect cable and hose carriers offer several key advantages, including enhanced cable protection, optimized performance in demanding applications, and modular design for easy customization and installation. Of utmost importance in the design of the system is the arrangement and placement of cables and hoses within the cavity of the cable carrier.

To assist in guiding the design process, the following guidelines and information will be extremely helpful in laying out a new system.

Why worry about where cables and hoses are placed in a cable carrier?

Both weight distribution and arrangement between cables and hoses play a critical role in the overall life of a system. Cavity separation plays a critical role in maintaining proper function and life expectancy in your application.

Cables and hoses that are different in diameter need to be carefully evaluated on where they are placed within the cable carrier cavity. Also, cables and hoses with different outer jacket materials (i.e.: PVC / PUR materials) need to be laid out separately using separation components.

In addition, applications with high cycle (back and forth travel) frequency requirements require exact positioning and arrangement of cable/hose package. An approach where the cables and hoses are just laid into the cable carrier without any consideration of separation just won’t perform to expectations. They can become tangled or stuck together, causing corkscrewing or severe wear on the outer jackets which leads to premature failure.

#1

If OD1 + OD2 > 1.2 x B (inner cavity height), then no separation is required.

#2

If OD3 + OD4 < 1.2 x B (inner cavity height), then vertical or horizontal separation is required.

Other Guidelines for Distribution:

Try to avoid stacking cables / hoses on top of one another. Consult the factory for recommendations.

The cables / hoses should be distributed within the cavity space by working from outside to inside, heavier
on the outside and lighter on the inside. This ensures optimum stability, balance, and straight running of
the system.

Cables and hoses should always be constrained (i.e.: clamp, strain relieved) at the ends so the system acts as a single unit. At minimum they should be clamped at the moving end but optimally both ends. Hydraulic hoses should be clamped at the moving end only in most cases.

Stacking cables and/or hoses on top of each other in high cycle applications should be avoided.

This information is provided as best practice and guidance to ensure your Dynatect cable and hose carrier system performs as expected. If you have any questions at all, please contact us at 1-262-786-1500 and we would be happy to assist you with your needs.

Note: While best practices call for constraining cables and hoses at both ends, Dynatect offers standard brackets with or without integrated strain relief to support space-limited installations and customers who prefer to supply their own clamping solutions.
