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.

The invention relates to a device for transporting loads, comprising at least two load lifting elements (20; 21), each element being mounted on horizontally movable slide arms (30; 31) which can be moved relative to one another by drive elements, wherein the slide arms (30; 31) are mounted on at least one sliding guide body (50; 51) and can be moved along the at least one sliding guide body (50; 51) by the drive elements. Each load lifting element (20; 21) is additionally mounted on movable guide arms (60; 61) which are guided on at least one guide rail (70), wherein the at least one sliding guide body (50; 51) and the at least one guide rail (70) are connected to one another and spaced apart from one another by at least one connecting element (80; 81). According to the invention, the drive elements are situated in the interior of the at least one sliding guide body (50; 51), and the slide arms (30; 31) are guided movably within the at least one sliding guide body (50; 51), wherein a sliding guide body (50; 51) has at least one longitudinal slot (52; 53) through which a connecting portion (32; 33) of a slide arm (30; 31) projects out of the sliding guide body (50; 51) and is connected to a load lifting element (20; 21).

A load-handling apparatus (1) adapted to be mounted on an elevatable lift carriage of a lift truck. Such a load-handling apparatus comprises at least four parallel guides (5, 7, 9, 11) making up a first pair (13) of parallel abutting guides(5,7) and a second pair(15) of parallel abutting guides (9, 11), at least two oppositely directed and hydraulic actuated piston cylinders (25, 27), wherein at least two load-handling arms (3) are connectable to said hydraulic actuated piston cylinders for moving said load-handling arms over said guides to and from each other for engaging a load. Each load- handling arm is moveably supported by one guide of each pair. In addition, the second pair is spaced of said first pair with a distance defined by connection elements lying between the first and the second pair in such a way that said connection elements only influence one dimension of the load-handling apparatus. This influence of said connection elements defines a viewing window between said first and second pairs and said connection elements through which a first side of the load-handling apparatus can be viewed from a second side of the load-handling apparatus.
