Abstract A device for raising and lowering objects which includes a stand (1), an arm (5) pivotably supported on the stand for carrying a bed frame or the like, a power mechanism (8) for pivoting the arm (5) and a wedge (12) which is insertable between portions of the stand and arm in order to actuate these portions away from each other and thereby pivot the arm upwardly from the stand. The wedge (12) is movable perpendicularly to the pivot axis (6) of the arm (5) and is connected to a dog (18) adapted to abut a component (28) connected to the arm (5) after a certain initial introduction of the wedge between said portions (9, 10).
