Automatically secured and guided: e-chain® design study with retractable pins for automatic securing

The "lokchain" design study has pins that are integrated in the side section and hold the chain securely in a profiled guide. If a chain link is bent into a curve, the pin retracts and releases the chain from the guide. It can be used in any conceivable mounting position thanks to the secure guiding. When used for circular movements, secure "locking" of the chain in a guide trough can revolutionise the way in which energy is supplied and can enormously increase operational safety.


Application example: e-chains® lokchain are used in X-ray machines.
