1. A crosshead (1) for use as an upper or lower beam (50, 60) in a press (100), comprising:
an upper chord (2);
a lower chord (5), the lower chord (5) being connected to the upper chord (2) via two lateral uprights (3, 4), including
a first lateral upright (3) and
a second lateral upright (4),
wherein the first lateral upright (3) is arranged in a region of a first distal end (6) of the crosshead (1),
wherein the second lateral upright (4) is arranged in a region of a second distal end (7) of the crosshead (1),
wherein the crosshead (1) has a truss support structure (8) between the two lateral uprights (3, 4) by which the upper chord (2) and the lower chord (5) are connected to one another,
wherein each of the upper chord (2) and the lower chord (5) has a central opening (9, 10), the central openings (9, 10) being centrally arranged and in alignment with one another,
wherein the central openings (9, 10) define a central region (11) of the crosshead (1), and the central openings (9, 10) are provided for connection to a main cylinder (110) of the press (100),
wherein each of the upper chord (2) and the lower chord (5) comprises, on both sides of the respective central opening (9, 10), respective further openings (12, 13, 14, 15) which are pairwise in alignment with one another, for connection to a first and a second press cylinder (111, 112) of the press (100),
wherein the truss support structure (8) comprises a plurality of transversely extending tension ribs (20, 21, 22, 23) that extend from the central region (11) of the lower chord (5) towards end faces of the upper chord (24, 25) and are fixedly connected to the lateral uprights (3, 4),
wherein two respective tension ribs of the plurality of transversely extending tension ribs (20, 21, 22, 23) arranged parallel to one another are each connected to one another via a flat element (26, 27), and
wherein each of the flat elements (26, 27) has an opening (28, 29) that is in alignment with a pair of the further openings (12, 13, 14, 15).
 
9. A press (100), comprising at least one crosshead (1) forming an upper or lower beam (50, 60) thereof, the at least one crosshead (1) comprising:
an upper chord (2);
a lower chord (5), the lower chord (5) being connected to the upper chord (2) via
two lateral uprights (3, 4), including
a first lateral upright (3) and
a second lateral upright (4),
wherein the first lateral upright (3) is arranged in a region of a first distal end (6) of the crosshead (1),
wherein the second lateral upright (4) is arranged in a region of a second distal end (7) of the crosshead (1),
wherein the crosshead (1) has a truss support structure (8) between the two lateral uprights (3, 4) by which the upper chord (2) and the lower chord (5) are connected to one another,
wherein each of the upper chord (2) and the lower chord (5) has a central opening (9, 10), the central openings (9, 10) being centrally arranged and in alignment with one another,
wherein the central openings (9, 10) define a central region (11) of the crosshead (1), and the central openings (9, 10) are provided for connection to a main cylinder (110) of the press (100),
wherein each of the upper chord (2) and the lower chord (5) comprises, on both sides of the respective central opening (9, 10), respective further openings (12, 13, 14, 15) which are pairwise in alignment with one another, for connection to a first and a second press cylinder (111, 112) of the press (100),
wherein the truss support structure (8) comprises a plurality of transversely extending tension ribs (20, 21, 22, 23) that extend from the central region (11) of the lower chord (5) towards end faces of the upper chord (24, 25) and are fixedly connected to the lateral uprights (3, 4),
wherein two respective tension ribs of the plurality of transversely extending tension ribs (20, 21, 22, 23) arranged parallel to one another are each connected to one another via a flat element (26, 27), and
wherein each of the flat elements (26, 27) has an opening (28, 29) that is in alignment with a pair of the further openings (12, 13, 14, 15).
 
10. An open-die forging press or a closed-die forging press, comprising at least one crosshead (1) having
an upper chord (2);
a lower chord (5), the lower chord (5) being connected to the upper chord (2) via
two lateral uprights (3, 4), including
a first lateral upright (3) and
a second lateral upright (4),
wherein the first lateral upright (3) is arranged in a region of a first distal end (6) of the crosshead (1),
wherein the second lateral upright (4) is arranged in a region of a second distal end (7) of the crosshead (1),
wherein the crosshead (1) has a truss support structure (8) between the two lateral uprights (3, 4) by which the upper chord (2) and the lower chord (5) are connected to one another,
wherein each of the upper chord (2) and the lower chord (5) has a central opening (9, 10), the central openings (9, 10) being centrally arranged and in alignment with one another,
wherein the central openings (9, 10) define a central region (11) of the crosshead (1), and the central openings (9, 10) are provided for connection to a main cylinder (110) of the press (100),
wherein each of the upper chord (2) and the lower chord (5) comprises, on both sides of the respective central opening (9, 10), respective further openings (12, 13, 14, 15) which are pairwise in alignment with one another, for connection to a first and a second press cylinder (111, 112) of the press (100),
