e-spool®: spring-driven cable drum with no slip ring

Spring cable drums e-spool without slip ring for telescopic applications, platforms and cranes

The e-spool spring cable drums from igus ensure that portable machines and systems are supplied with energy, data, compressed air and liquids safely, even under the most difficult conditions in the smallest of spaces. Compared to the classic cable drum, the e-spool is the only solution that can not only carry energy, but also all media such as data, compressed air and liquids. Examples: e-spool in the event hall, in automated high-bay warehouses, in cable robots, in stage technology or in steelworks.

All igus e-spool spring cable drums consist of an energy chain that is guided by a roller and ensures that the energy supply system is exactly at the right length and tension at all times thanks to an integrated retaining spring. And a twisterband is responsible for the rotary movements. This special structure makes movements in every direction possible. By using the twisterband, the e-spool does not require a slip ring. This makes data transmission highly reliable, while enabling a high degree of stability at the same time. Furthermore, the e-spool can be guided in all directions (horizontally, vertically, diagonally) and saves space, since the energy chain is rolled up in the starting position, thereby leaving the paths free.

FAQ - frequently asked questions

When various different cables need to be guided in very confined spaces. Different media (power, air and fluids) can be guided in one system.

Due to the special mechanical stress in an e-spool, we recommend using igus chainflex cables. In addition, we advise you to observe the following distribution rules:

In the case of unshielded cables, use cables with a TPE outer jacket wherever possible.
Use shielded cables from the CFROBOT family.
Make sure that all cables should have an outer diameter of <17mm.
Do not exceed the maximum bend radii of 44mm in the inner radius and 77mm in the outer radius.

Be inspired - examples from the real world with e-spool

The e-spool spring cable drums ensure uninterrupted supply of energy, data, air and liquids in the convention and cultural centre in Torun. A total of ten HD e-spool systems have been installed.

The e-spool spring cable drum is used in a telescopic wind machine. The wind machine prevents frost from destroying buds and young shoots in orchards, which would result in crop failures.

distribution rules for e-spool spring cable drums

Due to the special mechanical stress in an e-spool, we recommend using our chainflex cables. Additionally, we recommend observing the following distribution rules:

1. Cables may only be laid next to each other in the linear chain - never lay several cables on top of each other!
2. With unshielded cables, chainflex cables with TPE outer jacket should be used wherever possible.
3. Shielded cables should come from the chainflex cable family CFROBOT family.
4. The maximum bend radii of the twisterband used must be observed.
5. If possible, use separators to protect cables against overlapping and abrasion. To make the best possible use of the interior space, install separators in alternate segments.
6. Lay cables according to diameter or insert bend radius - thin small ones inwards and larger ones outwards.
7. Apply strain relief to both ends of the cable. The cable tie knot must not be fitted in the direction of the chain.
8. The cables should be installed in the twisterband with clearance space both outwards and inwards from the rotary axis.

Installation instructions

In the case of a horizontally travelling application, a smooth surface must be provided on which the energy chain can travel.

Outdoor applications
e-spool applications that are operated overhead in public spaces (spectator stands, stages, etc.)

For these applications, the e-spool system may need to be specially secured. Please get in touch with your sales representative.
