e-spool® - the alternative to the cable drum without slip ring

Safely guide many different cables in a confined space with e-spool. e-spool uniquely combines two different energy supply systems: one standard energy chain is guided by a roller, providing the correct length and tension of the energy supply system through an integrated spring. In the home position, the energy chain is completely rolled up to save space. The twisterband connects the roller with the shaft end block, serving as an interface to the supply side cables.

  • No tensile strain on the cables
  • Energy supply is possible in all directions (horizontal, vertical, diagonal)
  • Space-saving, no "chain station", as the energy chain is rolled up in the starting position, ensuring the paths remain clear
  • Cables can be retrospectively added or changed
  • Maximum extension and retraction speed 1m/s

Typical industries and applications

  • Telescopic applications
  • Lighting systems/stage technology (the standard e-spool is not in accordance with the stage technology guidelines DIN EN 17206. If you have questions, please contact your local Sales Engineer.)
  • Space-saving alternative to zig-zag solutions
Please contact us if you have one of the following application parameters:
  • Outdoor applications
  • e-spool applications that are operated overhead in the public area (spectator stands, stages, etc.)
For the applications mentioned, the e-spool system may have to be specially secured.
Please contact your sales representative.

When to use the e-spool system:

  • When many different cables should be routed in very confined spaces
  • When different media (power, data and fluids) can be routed together in one system

When to use another system:

  • For cables with large bend radii
  • With very high loads that have to be guided vertically
  • With overhead applications in a public area

Filling guidelines for the e-spool

Due to the special mechanical stress in an e-spool, we recommend using our chainflex cables. Additionally, we recommend observing the following filling 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 the separator 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 moving application, a smooth surface must be provided on which the energy chain can travel.
