A modular assembly for manufacturing structures for lateral translation and/or support of forks in lift trucks, which is formed of a first frame designed to be fastened to the lifting members of a lift truck and of a second movable frame to be mounted on the first frame to slide thereon through of rollers and/or runners and laterally moved, upon command, on the first frame by means of an actuator. The second frame is provided with hooking means for fastening of forks thereto, so that said forks project therefrom at the front. The first frame too is provided with hooking means of its own for direct fastening of forks, as an alternative to mounting of the second frame thereon, the second frame being made to be removable from the first frame. Runner or roller elements can be mounted in different ways to obtain the different sliding arrangements between the frames.

What is claimed is: 1. A modular assembly for manufacturing structures for lateral translation and support of forks in lift trucks, comprising: a first frame designed to be fastened to the lifting members of a lift truck and provided with upper hooking means for fastening of forks thereto; a second frame designed to be slidably mounted on the first frame and provided with upper hooking means for fastening of forks thereto; and wherein the first frame and the second frame are provided with mounting means for laterally slidable and removable mounting of the second frame on the first frame to be laterally movable, upon command, on the first frame by means of an actuator, characterized in that the means for laterally slidable and removable mounting of the second frame on the first frame are separated from and independent of the upper hooking means for fastening of the forks to the first frame and are disposed below said upper hooking means for fastening of the forks to the first frame. 2. An assembly as claimed in claim 1. characterized in that the means for laterally slidable and removable mounting of the second frame on the first frame is comprised of rollers and/or runners sliding on shaped guides disposed between an upper horizontal bar and a lower horizontal bar of the frames. 3. An assembly as claimed, in claim 1, characterized in that for slidable mounting of the second frame on the first one, the first frame comprises: a horizontal track surface in the vicinity of a lower side of the first frame and designed for sliding of corresponding first runners to be mounted or already mounted on the second frame; a horizontal track on the first frame in the vicinity of an upper side of the first frame and designed for slidable fining of corresponding further runners to be mounted or already mounted on the second frame; a second horizontal track surface at a position close to a lower side of the first frame and designed to receive a pair of rollers to be mounted or already mounted on the second frame. 4. An assembly as claimed in claim 1, characterized in that for fastening to the lifting members of a truck, the first frame comprises a pair of vertical plates projecting therefrom at the rear. 5. An assembly as claimed in claim 4, characterized in. that, for slidable mounting of the second frame on the first frame, the first frame comprises, on each of said plates of the pair, holes for fastening of a sliding roller Conning a slidable rest for a track surface present on the second frame. 6. An assembly as claimed in claim 5, characterized in that the means for laterally slidable and removable mounting of the second frame on the first frame is comprised of rollers and/or runners sliding on shaped guides disposed between an upper horizontal bar and a lower horizontal bar of the frames; and characterized in that each sliding roller is fastened to the respective plate of the first frame at a position close to an upper horizontal crosspiece of the first frame, and the suitable track surface formed on the second frame is supported by an upper horizontal crosspiece of the second frame. 7. An assembly as claimed in claim 5, characterized in that for slidable mounting of said second frame on the first frame, the second frame comprises at least one pair of sliding rollers mounted thereon and resting on a horizontal track surface formed on the first frame and in that the assembly simultaneously comprises two of said sliding rollers mounted on the first frame and two of said sliding rollers mounted on the second frame. 8. An assembly as claimed in claim 1, characterized in that the second frame, for slidable mounting of said second frame on the first frame, comprises at least one pair of sliding rollers mounted thereon and resting on a horizontal track surface formed on the first frame. 9. An assembly as claimed in claim 8, characterized in that the suitable track surface for support of the pair of rollers is formed on the first frame at a position close to a lower horizontal crosspiece of the first frame. 10. An assembly as claimed in claim 9, characterized in that for slidable mounting of the second frame on the first frame, a runner means is present which consists of a horizontal tack on the first frame, in the vicinity of an upper side thereof and on which corresponding sliding runners present on the second frame slidably fit and in that the assembly simultaneously comprises said runner means and the pair of rollers resting on the track surface close to the lower horizontal crosspiece of the first frame. 11. An assembly as claimed in claim 1, characterized in that for slidable mounting of the second frame on the first frame, a first runner means is present which consists of a first horizontal track surface on the first frame, in the vicinity of a lower side thereof and on which corresponding sliding runners present on the second frame rest. 12. An assembly as claimed in claim 11, characterized in that for slidable mounting of the second frame on the first frame, a second runner means is present which consists of a horizontal track on the first frame, in the vicinity of an upper side thereof and on which corresponding sliding runners present on the second frame slidably fit and in that the assembly simultaneously comprises the first and second runner means. 13. An assembly as claimed in claim 12, characterized in that said sliding runners of the second runner means have the conformation of a U-shaped channel and in that said track surface supported by an upper horizontal crosspiece of the second frame, and said U-shaped channel can be dismantled from the second frame and the track surface and U-shaped channel are replaceable with each other. 14. An assembly as claimed in claim 1, characterized in that for slidable mounting of the second frame on the first frame, a runner means is present which consists of a horizontal track on the first frame, in the vicinity of an upper side thereof and on which corresponding sliding runners present on the second frame slidably fit. 15. An assembly as claimed in claim 14, characterized in that said sliding runners of the said runner means have the conformation of a U-shaped channel. 16. An assembly as claimed in claim 1, characterized in that the first frame comprises a plate for mounting of said actuator, which is disposed at a centered position with respect to side edges of the first frame and in the vicinity of a lower edge of the first frame. 17. An assembly as claimed in claim 16, characterized in that the actuator is a double-rod hydraulic actuator and is hooked to the second frame by means of its opposite two rods. 18. An assembly as claimed in claim 1, characterized in that the actuator is an electric actuator. 19. An assembly as claimed in claim 1. characterized in that the hooking means for fastening of the forks to the first and second frames comprises a hooking step formed along an upper edge of the upper bar and along a lower edge of the lower bar of the frames, in compliance with UNI ISO 2328 specifications.
