Abstract The invention relates to a rotary table (1) for positioning a workpiece by means of a manual drive (4a, 4b), said rotary table comprising a base plate (2) having a base plate-side transmission device (20), and also comprising a bearing plate (3), mounted rotatably on the base plate and having a bearing plate-side transmission device (30), which is configured to rotate the bearing plate (3) relative to the base plate (2) by means of a drive (4), wherein the base plate (2) is formed as a two-part or multi-part component composed of at least two plate segments (2a, 2b), and wherein the bearing plate (3) is formed as a two-part or multi-part component composed of at least two plate segments (3a, 3b). ## Claims ### Claim 1 A rotary table for positioning a workpiece by means of a manual drive, said rotary table comprising a base plate having a base plate-side transmission device, and also comprising a bearing plate, mounted rotatably on the base plate and having a bearing plate-side transmission device, which is configured to rotate the bearing plate relative to the base plate by means of a drive, wherein the base plate is formed as a two-part or multi-part component composed of at least two plate segments, and wherein the bearing plate is formed as a two-part or multi-part component composed of at least two plate segments. ### Claim 2 (depends on 1) The rotary table according to claim 1, wherein the base plate is formed from two separate plate segments, which are connected to one another via locking means. ### Claim 3 (depends on 1) The rotary table according to claim 1, wherein the base plate is configured as a cylindrical plate having a central round opening. ### Claim 4 (depends on 1) The rotary table according to claim 1, wherein the bearing plate is configured as a cylindrical plate having a central opening. ### Claim 5 (depends on 4) The rotary table according to claim 4, wherein a radial bearing protrudes outward on the underside of the bearing plate around the central opening and extends into the central opening of the base plate. ### Claim 6 (depends on 1) The rotary table according to claim 1, wherein each of the plate segments of the bearing plate is configured as a bearing cage having a plurality of bearing rollers that protrude outward from the plate plane on the underside of the bearing plate. ### Claim 7 (depends on 6) The rotary table according to claim 6, wherein the bearing cage forms a plurality of radially extending rows of through openings, arranged one behind the other and spaced from one another, in which the bearing rollers are respectively mounted. ### Claim 8 (depends on 6) The rotary table according to claim 6, wherein each of the bearing rollers arranged one behind the other in a row is mounted on a shaft, which is installed in a radial direction and which preferably extends up to the edge face of the bearing plate, and which in some cases protrudes outward on the face side from the bearing plate with face-side shaft sections. ### Claim 9 (depends on 8) The rotary table according to claim 8, wherein the bearing plate-side transmission device is formed at least partially by shaft sections of the shaft or bolts protruding from the face side of the bearing plate, on which a manual ratchet can be mounted. ### Claim 10 (depends on 1) The rotary table according to claim 1, wherein a manual ratchet having a lever arm and a ratchet member is further provided, which is mounted on the bearing plate-side transmission device in order to bring the ratchet member in engagement with the base plate-side transmission device by actuating the manual ratchet about a radially extending rotational axis. ### Claim 11 (depends on 1) The rotary table according to claim 1, wherein the plate segments of the base plate and/or the plate segments of the bearing plate are configured as hermaphroditic plate segments. ### Claim 12 (depends on 1) The rotary table according to claim 1, wherein an at least two-part cover plate having a central opening is provided on the bearing plate. ### Claim 13 (depends on 1) The rotary table according to claim 1, wherein above the bearing plate an integral support plate having a central opening is provided, said opening extending to the edge of the support plate with a width that is substantially equal to the diameter of the central opening, resulting in an approximately U-shaped plate overall. ### Claim 14 (depends on 13) The rotary table according to claim 13, wherein on the support plate at least one lifting device is provided, preferably two lifting cylinders, which are arranged symmetrically to the central opening on the support plate. ### Claim 15 (depends on 1) The rotary table according to claim 1, wherein on the underside of the base plate a plurality of feet are mounted, which are preferably cylindrical in shape and which further preferably protrude with at least one foot segment beyond the edge of the base plate.
