Zusammenfassung:	A device for lifting a load for a lift truck comprising a supporting frame (2) configured to support at least one upright unit (26);the upright unit (26) is configured to support an element (15) for picking up a load;first movement means (16) are configured for moving the picking-up element (15) at least from a first height to a second height, greater than the first height, and vice versa;the first movement means (16) comprise a pair of telescopic cylinders (17, 18), a first telescopic cylinder (17) and a second telescopic cylinder (18), each configured to pass at least from a retracted configuration, corresponding to a respective first height of the picking-up element (15), to an extended configuration, corresponding to a respective second height of the picking-up element (15), and vice versa, forming a free lift of the picking-up element (15);the first telescopic cylinder (17) and the second telescopic cylinder (18) are configured for achieving a 1:1 transmission ratio for moving the picking-up element (15) from the retracted configuration to the extended configuration, and vice versa.
