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

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

Spring cable drums e-spool® (also known as spring cable drums) from igus® ensure a reliable supply of power, data, compressed air and fluids to mobile machines and systems, even under the most difficult conditions in the tightest of spaces. Compared to the classic cable drum, the e-spool® is the only solution that can carry not only energy, but also all media such as data, compressed air and fluids. 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 reels consist of an energy chain, which is guided by a roller and ensures exactly the right length and tension of the energy supply at all times thanks to an integrated retaining spring. And a twisterband is responsible for the rotary movements. This special design makes movements in any direction possible. Thanks to the use of the twisterband, the e-spool® does not require a slip ring. This enables high data transmission reliability and great stability. In addition, the e-spool® can be routed in all directions (horizontally, vertically, diagonally) and space-saving, as the energy chain is rolled up in the starting position, leaving the paths free.

FAQ - frequently asked questions

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

In view of the special mechanical stress inside an e-spool, we recommend using igus chainflex cables. We also recommend that the following guidelines are observed:

Where possible, cables with a TPE outer jacket should be used for unshielded cables.
Shielded cables should be chosen from the CFROBOT range.
All cables should have an outside diameter of < 17mm.
The maximum bend radii of 44mm in the inner radius and 77mm in the outer radius are observed.

Filling rules for e-spool® spring cable reels

Due to the special mechanical stress in an e-spool®, we recommend using our chainflex® cable. We also recommend adhering to the following filling rules:

1. cables may only be laid side by side in the linear chain - never lay several cables on top of each other!
2. chainflex® cables with a TPE outer jacket should be used for unshielded cables wherever possible.
3. shielded cables should be from the chainflex® CFROBOT cable family.
4. the maximum bend radius of the twisterband used must be observed.
5. if possible, use separators to protect cables against flashover and abrasion. To make the best possible use of the interior space, install separators alternately in consecutive segments.
6. Insert cable sorted by diameter or bend radius - insert thin, small cables towards the inside and larger ones towards the outside.
7. Relieve the strain on both ends of the cable. The cable tie knot must not be fitted in the direction of the chain.
8. the cables should be laid in the twisterband in such a way that they have some clearance space both outwards and inwards to 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.
