The igus® E-Chain® B17 was just completely alienated from its intended purpose for this clever application: As a robust, maintenance-free conveyor system, it does its job on a miniature golf course. As a result, this energy chain® was joined to form a closed circle, and the separating web on every fourth link was removed so that the golf balls could be picked up. After being holed, the balls are silently transported back to the player using the E-Chain®.
