Emergency stop device

Abstract

An emergency stop device for a shuttle moveable in a horizontal plane on two elongated rails arranged in parallel includes at least one pressure biased locking shoulder displaceable in a horizontal plane, and at least one stabilizing wheel arranged together with the locking shoulder in a holder and protruding outside the locking shoulder, wherein the stabilizing wheel is rotatable in a horizontal plane. The locking shoulder and the stabilizing wheel together have an extension such that they together can be received, at least partially in a hole provided in a substantially vertical web of the rails at an end portion of the rail, when biased by the pressure bias. A frictional coupling is arranged between the shuttle and holder and allows limited movement of the shuttle in the horizontal plane after the locking shoulder has reached a locked position vis-à-vis the rails. Further, a stockroom system includes a plurality of pairs of parallel, elongated rails, arranged in a horizontal plane, and a shuttle movable on a pair of rails, and along the rails, wherein each rail is designed with a substantially vertical web and at least one protruding horizontal portion for bearing of load, the at least one protruding horizontal portion protruding from the substantially vertical web, wherein the stockroom system comprises an emergency stop device according to the above.
