e-spool® compact - spring driven cable drum without slip ring
The compact e-spool for extensions of 2m and 4m are space-optimised systems with smaller linear chains and twisterbands for a wide range of applications with limited space. Interference-free transmission and flexible filling.
- Different media (power, data, optic fibre, air, liquids) can be combined in one system
- Energy supply in all directions
- Simple replacement and expansion of the filling
- Space-saving and virtually "invisible"
- Particularly light aluminium design for SP1.240 series
- Max. extension and retraction speed of 1m/s
- Particularly light aluminium design
Typical application areas:
Manual workplaces, work stations, assembly lines, small telescopic applications
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.

Distribution rules for the e-spool
Due to the particular mechanical stress in an e-spool, we recommend using our chainflex cables. We also advise operators to follow these distribution rules:
1. In the linear chain, cables may only lie side by side - never place several cables on top of each other!
2. In the case of unshielded cables, use chainflex cables with a TPE outer jacket wherever possible.
3. Use shielded cables from the chainflex CFROBOT range.
4. Observe the maximum bend radius of the twisterband used.
5. If possible, use separators to protect cables from intertwining and abrasion. To make the best possible use of the interior space, install separators alternately in consecutive segments.
6. Sort the cables you would like to insert according to diameter or bend radius - insert thin, small cables towards the inside and larger ones towards the outside.
7. Relieve the strain on the cable at both ends. The cable tiewrap knot must not face the chain.
8. Lay the cables in the twisterband in such a way that they have some distance/clearance space both outwards and inwards towards the rotary axis.
Installation instructions
In the case of a horizontally travelling application, the energy chain must be able to move on a smooth surface.
Assembly instructions
Realised in practice
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.
