Abstract:
1. A device for picking up loads, wherein said device is or can be attached to another piece of equipment, having a frame, first and second load pick-up elements, wherein the first and second load pick-up elements are configured so as to move on the frame along a direction of motion in a straight line, first and second drive units that are installed on the frame and arranged above one another, wherein each of the first and second drive units has a drive element and is configured to selectively move said drive elements in the following manners: independently of each other; and only one drive element can be moved, while the other drive element stands still, wherein at least a first pair of deflection means is rigidly installed on the drive element of the first drive unit, and wherein at least a second pair of deflection means is rigidly installed on the drive element of the second drive unit, and wherein deflection elements of each pair of deflection means are at a distance from each other in the direction of motion, wherein, for each of the deflection elements of each pair of deflection means, there is a force-transmission means that has a first attachment section and a second attachment section, wherein each force-transmission means of the first pair of deflection means and of the second pair of deflection means is attached by means of the first attachment section to a prescribed area of the frame, wherein each force-transmission means of the first pair of deflection means is attached by means of the second attachment section to the first load pick-up element, wherein each force-transmission means of the second pair of deflection means is attached by means of the second attachment section to the second load pick-up element, and wherein each deflection means of a pair of deflection means is engaged with an appertaining force-transmission means between the first attachment section and the second attachment section, and wherein a movement of the drive element of the first drive unit brought about by activating the first drive unit can be converted—via the deflection means of the first pair of deflection means and via the force-transmission means provided for the first pair of deflection means—into a corresponding movement of the first load pick-up element, and wherein a movement of the drive element of the second drive unit brought about by activating the second drive unit can be converted—via the deflection means of the second pair of deflection means and via the force-transmission means provided for the second pair of deflection means—into a corresponding movement of the second load pick-up element.
