A conveying unit for suspended transport of transport elements (40, 240, 340, 540, 550) in a conveying system, particularly a rail-guided conveying system or a conveyor chain system, with a conveying element with a conveying direction, in particular a trolley or a conveyor chain link, with a support hook (21, 321a, 521a) attached to the conveying element, a transport element (40, 240, 340, 540, 550), and a suspension hook (41, 241, 341a, 441a, 541a) attached to the transport element, wherein the suspension hook is mounted in a suspended manner in the support hook; wherein the support hook (21, 321a, 521a) is designed such that the suspension hook (41, 241, 341a, 441a, 541a) can assume at least two stable positions (61, 62) in the support hook, wherein the suspension hook in a first stable position is rotated by an angle relative to the suspension hook in a second stable position. wherein the support hook (21, 321a, 521a) includes a first support segment on which, in a given first spatial orientation of the support hook, the suspension hook can be supported in the first stable position in which the suspension hook is aligned in a first plane; and wherein the support hook (21, 321a, 521a) includes a second support segment, on which, in a certain second spatial orientation of the support hook, which is identical to or different from the first spatial orientation, the suspension hook can be supported in the second stable position, in which the suspension hook is aligned in a second plane; wherein the suspension hook is transferable back and forth between the first position and the second position; and characterized in that the first plane in which the suspension hook (41, 241, 341a, 441a, 541a) is aligned in the first stable position is substantially perpendicular to the conveying direction; and the second plane in which the suspension hook is aligned in the second stable position is substantially parallel to the conveying direction. with a conveying element with a conveying direction, in particular a trolley or a conveyor chain link, with a support hook (21, 321a, 521a) attached to the conveying element, a transport element (40, 240, 340, 540, 550), and a suspension hook (41, 241, 341a, 441a, 541a) attached to the transport element, wherein the suspension hook is mounted in a suspended manner in the support hook; wherein the support hook (21, 321a, 521a) is designed such that the suspension hook (41, 241, 341a, 441a, 541a) can assume at least two stable positions (61, 62) in the support hook, wherein the suspension hook in a first stable position is rotated by an angle relative to the suspension hook in a second stable position. wherein the support hook (21, 321a, 521a) includes a first support segment on which, in a given first spatial orientation of the support hook, the suspension hook can be supported in the first stable position in which the suspension hook is aligned in a first plane; and wherein the support hook (21, 321a, 521a) includes a second support segment, on which, in a certain second spatial orientation of the support hook, which is identical to or different from the first spatial orientation, the suspension hook can be supported in the second stable position, in which the suspension hook is aligned in a second plane; wherein the suspension hook is transferable back and forth between the first position and the second position; and characterized in that the first plane in which the suspension hook (41, 241, 341a, 441a, 541a) is aligned in the first stable position is substantially perpendicular to the conveying direction; and the second plane in which the suspension hook is aligned in the second stable position is substantially parallel to the conveying direction.
