Abstract: Embodiments of the subject innovation relate to a device for picking up loads, having a frame, two load pick-up elements that are configured so as to move lengthwise on the frame, two drive units that are installed on the frame and arranged one above the other, whereby each drive unit has a drive element and is configured to move this drive element relative to the frame in two opposite directions parallel to the direction of motion of the load pick-up elements, whereby force-transmissions and deflectors are provided on the drive elements. By activating the drive units, a movement of the drive elements can be converted into a corresponding movement of the appertaining load pick-up elements.
