Abstract: A transport system has at least one track, preferably hung on supports or hanging from cables, on which transport cars may travel, by at east one trolley. Several running wheels are provided in the trolley and the trolley may be actively rotated about the axis of the track relative to the transport car. Branchings are provided in the track, in which the track divides into two track branches. In the vicinity of the branching lies an intersection of the outer surfaces of the track branches, such that on each of the upper side and the lower side there are two grooves due to the intersection, which meet in the vicinity of the gusset, between the two track branches. Between the grooves, on both the upper and lower side, is a tapering web, the surfaces of which are part of the surface area of the track branches.

Abstract: A releasable turnstile lock with a star-type rotating body (4) which can be driven by a motor which is controllable by a control unit, from which body project two arms (1, 2) which are substantially rigidly connected with the star-type rotating body (4) and enclose an angle with a rotational axle of the star-type rotating body (4), with one arm (1, 2) projecting substantially horizontally from the star-type rotating body (4) in a locking position and blocking a passage (9), characterized in that a position of the arms (1, 2). In order to allow an easy return to normal operation after the initiation of an alarm, it is provided that a position of the arms (1, 2) releasing the passage is provided which is controllable by the drive motor and in which the arms (1, 2) are disposed in a vertical plane extending substantially parallel to the passage.
