Lifter for loads, in particular a palletizer for stackable objects, comprising a load carrier which can be moved up and down, in particular an articulated swivel arm (16) on whose free end an element is arranged for seizing the objects, the up and down or lifting and lowering movements of the load carrier being effected along a vertical guide, in particular along upright columns (19), and a drive (13)for the lifting and lowering movement of the load carrier at the upper or lower end of the vertical guide (columns 19), the connection between the drive (13) and the load carrier (swivel arm 16) being made by a toothed belt (14) which on one side is passed around a pinion (15) allocated to the drive (13) and on the other side is passed around a toothed disc (17) rotatably mounted on the end of the vertical guide (columns 19) opposite the drive side and whose free ends are each attached to the load carrier or a guide block (26) of the same. To attach the free toothed-belt ends (10, 11) to the guide block (26) the former are each passed over a part of a toothed wheel, in particular a toothed half-wheel (toothed half-wheel roller 20, 21), fixed to the guide block (26), while the complementary toothed systems of toothed belt and toothed wheel or toothed roller engage positively.

Lifter for loads, in the form of a palletizer for stackable objects, comprising: a load carrier which is movable up and down and which is in the form of an articulated swivel arm (16) on whose free end means are arranged for seizing the objects, the up and down or lifting and lowering movement of the load carrier being effected along upright columns (19) of a vertical guide; and a drive (13) for the lifting and lowering movement of the load carrier at one of the upper and lower ends of the vertical guide (19), a connection between the drive (13) and the load carrier being made by a toothed belt (14) which on one side is passed around a pinion (15) allocated to the drive (13) and on the other side is passed around a toothed disc (17) rotatably mounted on the end of the vertical guide (19) opposite the drive side, and whose free ends (10, 11) are each attached to a guide block (26) of the load carrier; characterized in that the toothed-belt ends (10, 11) are attached to the guide block (26) of the load carrier (16), by, in each case, their passage over a segment of a respective toothed half-wheel, anchored to the guide block (26), so that complementary toothed systems of toothed belt and toothed wheel engage each other positively, the toothed-wheel anchoring segments, with the toothed belt (14) having an appropriate width, being designed as toothed-roller segments (20, 21).
