The invention relates to a device for performing turning of objects, in particular elongate objects which are round in cross-section, such as tree trunks (12). This is made possible by the device having two levers (1) which are interconnected but movable at least to a limited extent both longitudinally and turnably relative to each other via a hinge (8, 9). Hook members (4) are pivotally connected to the levers in such a manner that the levers can alternately be made to abut, by means of a part (3) supporting a circumferential surface, against the tree trunk while the associated hook member (4) engages the tree trunk. At the same time, the other lever can be turned and moved backwards towards the turning direction of the log so as to engage the tree trunk in a position further backwards relative to the first hook member. |
