Abstract
A load-lifting device comprises a generally horizontal frame to be lifted and a plurality of load-engaging carriers movable by means of actuators along said supporting frame in a direction, in which the carriers form a row. Every two adjacent carriers are interconnected by a group of actuators that is operable independently of all the other actuator groups, and only one of said interconnected carriers is connected to the frame by actuator means defining the position of all said interconnected carriers relative to the frame.
