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.
- All in one system: Different media (electricity, data, liquids) can be combined in one system
- Space-saving: Cable drum with spring drive without slip ring
- Simple installation: Subsequent addition and replacement of cables possible
- Extension lengths of up to 2m and 14m
- Maximum extension and retraction speed 1m/s
- No tensile strain on the cables
- Variable use - energy supply possible in all directions
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.
- e-spool flex and e-spool SPC with manual extension if only one cable has to be guided very slowly or by hand.
- e-spool theatre for overhead applications in public spaces
- All other e-spool spring cable drums must be selected according to the extension length and filling volume/cable diameter.
- e-spool flex with 10,000 movements
- e-spool standard with 70,000 cycles
- e-spool HD with 40,000 cycles
- e-spool theatre with 40,000 cycles
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.
Attention: Use the HD version in vertical applications where the energy chain is extended more than 4m downwards.

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.
Assembly instructions
Please contact us if you have one of the following application parameters:
- 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.
