A B S T R A C T A lifting device is used for live or practice ammunition, e.g. in the form of shells (10) for which the device comprises a number of gripping means. Said gripping means are made with a number of elements (2) extending from the frame (1) of the lifting device which elements form pairs of elements that can be allotted each to its shell during the lifting. The elements are rotatably supported around their longitudinal axes in the frame and at their free ends have widened sections extending in one direction. The elements are rotatable to first rotation positions where the respective pair of elements from the side can be moved over a round of ammunition. In second rotation positions for the elements the respective pair of elements encloses its shell with the aid of the widened sections and secures the shell against movement in the transversal direction. At the respective pair of elements there is also arranged a holding trough (8) which is rotatably suppported via its back section in the frame so that its parts directed towards the sections in the pair of elements in question carry out a displacing movement towards the sec- tions. Also a lifting hook (19) is included, which in one embodiment is connected with the holding troughs via a linkage system so that the rotary movements and positions of the holding troughs in relation to the sections (2d) of the elements are controlled with the aid of the own weight of the shells and the lifting device.
