[0049] FIG. 1 shows a three-dimensional front view of an embodiment of the system according to the invention 100 with load handling elements 191, 192 in a narrow position. In a first upper guide profile 120, two fork tines 191, 192 are attached. The fork tines 191, 192 are supported on a second, lower guide profile 130. The first guide profile 120 and the second guide profile 130 are arranged in parallel to each other and connected at a distance from each other by two vertical connection elements 140 in a frame-like manner. The load handling elements 190, 191 are connected by tappet plates 120, 135 that can in turn be moved horizontally relative to each other or in parallel to each other in the longitudinal direction of the guide profiles 120, 130 via drive elements 121, 131. The two guide profiles 120, 130 each have a hollow profile, wherein one drive element 121, 131 is integrated inside the respective guide profile 120, 130 in each guide profile 120, 130. Each guide profile 125, 135 has a longitudinal slit 122, 132 through which the holder of the respective tappet plate 125, 135 protrudes. The second longitudinal slit 132 in the second, lower guide profile 130 is facing outwards and therefore susceptible to the occurrence of contamination. A protection element 150 that is moved along with the second tappet plate 135 in the form of a strip closes this second longitudinal slit 132 upwards, thereby preventing contamination of the cavity in the second guide profile 130.
[0050] FIG. 2 shows a three-dimensional front view of an embodiment of the system according to the invention 100 with the second load handling element 192 that is attached to the first guide profile and in an outer position, i.e. in the position extended maximally from the centre of the device 110. The second tappet plate 135 is empty, so that the holding profile 136 is visible in the second tappet plate 135. The holding profile 136 in this embodiment comprises a U-shaped profile sized in width so that the two legs of the U can partially enclose the load handling elements 191, 192 used. The tappet plates 125, 135 create the connection of the lateral shifting drive to the fork tines 191, 192. Standard fork tines 191, 192 can be used due to the shape of the holding profile 126, 136.
[0051] FIG. 3 shows a three-dimensional rear view of an embodiment of the system according to the invention 100 with fork tines 191, 192 in an outer position. In this view, the guide means 121e, 131e are visible. On the one hand, the guide means 121e, 131e have the respective holder of the respective tappet plate 126, 136 in the form of a cuboid elevation on the respective end of the respective cylinder housing 121b, 131b opposite from the exit side of the respective piston rod 121c, 131c that protrude through the longitudinal slits 122, 132 towards the respective tappet plate 125, 135, wherein the longitudinal slits 122, 132 are designed so that they support and guide the cuboid elevations in the direction vertical to the movement direction. For this, the respective drive element 121, 131 is on one axis with the guide of the respective tappet plate 125, 135.
[0052] FIG. 4 shows a lateral section of a system according to the invention 100. The device 110 has a first upper attachment profile 111 and a second lower attachment profile 112 with which the device 110 can be installed on a movable or stationary facility, such as an industrial truck, by being attached to a corresponding counter-profile, e.g. of a vertically movable lifting carriage of the forklift truck. In the displayed embodiment, the first attachment profile 111 is firmly connected to the device 100, e.g. by welding. In contrast to this, the second attachment profile 112 is screwed to the device 100 so that the device 100 can initially be attached to the counter-profile of a lifting carriage with the first attachment profile 111 and then the second attachment profile 112 can be screwed on, so that the device is firmly connected to the lifting carriage in the travelling direction of the forklift truck and cannot tip, e.g. when pulling back after putting down a load. The figure shows the second fork tine 192 that is attached to the first holding profile 127 of the first guide profile 120 and the second holding profile 137 of the second guide profile 130 with its attachment profiles in 195. Furthermore, the first tappet plate 125 is shown in a section. The second tappet plate 135 is connected to the first drive element 121 of the first guide profile 120 with a screw as attachment means 121d via a cuboid elevation, wherein the cuboid elevation forms the first guide means 121e with the first longitudinal slit 122. Furthermore, the second guide profile 130 is visible in FIG. 4, which has the second cylinder housing 131b and the second piston rod 131c. Furthermore, the second longitudinal slit 132 and the strip 150 that covers the second longitudinal slit 132 as a protection element are visible. Both guide profiles 120, 130 reach around the drive element 121, 131 arranged inside them by approx. 90%. The guide profile 120, 130 reaching around the drive element 121, 131 protects the drive element 121, 131 in the guide profile 120, 130 and holds it so that it cannot bend or fold out even at application of great force.
[0053] FIG. 5 shows a section from above through the second guide profile 130. The connection head 131f is firmly connected to the frame and the second piston rod 131c is connected to the connection head 131f. The hydraulic oil runs through the second piston rod 131c via two ducts, once to the bottom side of the piston (load handling equipment moves apart) and once to the rod side of the piston in the second cylinder housing 131b (load handling equipment moves together). The second guide means 131e is connected to the movable second cylinder housing 131b. Sliding elements (not shown) are mounted between the second drive element 131 and the second guide profile 130. The first guide profile 120 is built accordingly.
[0054] FIG. 6 shows a three-dimensional illustration of a drive element 121, 131 with a tappet plate 125, 135.

[0055] FIG. 7 shows a three-dimensional illustration of another embodiment of a drive element 121, 131 with a tappet plate 125, 135. In contrast to the embodiment shown in FIG. 6, the tappet plates 125, 135 are attached to a sliding arm 121h, 131h that is driven by the respective piston rod 121c, 131c.
[0056] FIG. 8 shows a three-dimensional front view of an alternative embodiment of the system according to the invention 100 with the second load handling element 192, which is attached to the first guide profile. The second tappet plate 135 is empty, so that the holding profile 136 is visible in the second tappet plate 135. The holding profile 136 in this embodiment also comprises a U-shaped profile sized in width so that the two legs of the U can partially enclose the load handling elements 191, 192 used. The tappet plates 125, 135 create the connection of the lateral shifting drive to the fork tines 191, 192. Standard fork tines 191, 192 can be used due to the shape of the holding profile 126, 136. In the embodiment shown in FIG. 8, each tappet plate 125, 135 is driven via the respective drive element 121, 131 in a guide profile 120, 130 and additionally guided by the other guide profile 130, 120 as well, wherein both the first longitudinal slit 122 and the second longitudinal slit 132 face forward, i.e. in the expansion direction of the load handling elements 191, 192. The respective tappet plates 125, 135 do not need to be guided by the respective other guide profile 120, 130, but may also be guided only by one guide profile 120, 130. Furthermore, an embodiment is possible where either both longitudinal slits 122, 132 face up, i.e. in the direction opposite to the horizontal parts of the load handling elements 191, 192. As another embodiment, a system 100 according to the invention is also possible where the first longitudinal slit 122 points downwards in the direction of the second guide profile 130 and the second longitudinal slit 132 points upwards in the direction of the first guide profile 120. An inverted arrangement of the guide slits 122, 132 as compared to this is possible as well.
[0057] FIG. 9 shows a three-dimensional illustration of another embodiment of a drive element 121 with tappet plates 125, 136. In contrast to the drive elements shown in FIGS. 6 and 7, the first and second drive elements shown in FIG. 9 are on one level and can, as a result, be installed in a guide profile (not illustrated). A drive unit 160 is located between the first drive element 121 and the second drive element 131. This drive unit 160 can be, e.g., an electrical or fluid motor, e.g. a hydro motor. In this embodiment, the drive unit 160 drives both the first drive element 121 and the second drive element 131 rotatingly. Spindles are installed as drive elements 121, 131, e.g. ball screws or threaded spindles. The drive elements 121, 131 move sliding arms 121h, 131h on which the tappet plates 125, 135 can be attached. A gear can be integrated into the drive unit (not illustrated), which can be switched and which can reverse the rotating direction of a drive element 121, 131, so that both a lateral shifting movement in which the tappet plates 125, 135 are moved in parallel and in the same direction, and an opposite movement of the tappet plates 125, 135, as it is required for adjustment of the distance of the load handling elements 191, 192 (not illustrated) are possible.
