Igus now offers three E-spool solutions, depending on the pull-out direction and load. The standard E-spool features a simple spring mechanism for retracting the chain and is suitable for any direction. However, vertical applications require a higher retraction force, so the heavy-duty version has been designed with an extra tough spring. Finally, the motor version is designed for use with a motor to allow higher filling loads and movements in any direction.

E-spool combines two different energy chains: a standard Igus energy chain is routed via a spool and an Igus twisterband connects the spool with the shaft bracket, which serves as the interface to the permanently installed cables. Instead of featuring costly sliding contacts, the cables can be connected without interruption and can be replaced or modified at any time.

All three versions of E-spool are available in extension lengths of 0–4m, 4–7m and 7–14m and with one or two twisterbands depending on the cable capacity required. The maximum spooling speed is approximately 1m/sec and the twisterband enables cables with up to 17mm to be housed.

Key benefits

* Users can save space associated with storing the chain, as it has a smaller footprint than traditional zig-zag chains used in lifting applications.
* Claimed to be quick and easy to install, E-spool provides cables reliably in any direction for travel up to 14m.
* E-spool is claimed to be the only cabling solution that guides all media types, such as data, compressed air and liquids, flexibly and with minimum space in one system.
* E-spool is reliable and the plastic energy chain is easy to install and use; users can simply press the cables into the chain from the outside, without the chain links being opened and closed.
