The invention relates to a lift drive for a rail-guided cantilever construction device (2), in particular for use in bridge construction. The cantilever construction device (2) comprises a main frame (3, 3′) which is guided by at least one rail (4a, 4b, 4′a, 4′b) for receiving at least one formwork. The lift drive comprises a lift device (5, 5′), wherein a first end of the lift device (5, 5′) is designed to be connected to the main frame (3, 3′), and a second lift device (5, 5′) end opposite the first end can be moved relative to the main frame (3, 3′) when the first end of the lift device (5, 5′) is connected to the main frame (3, 3′); a first fixing device (6) which is connected to the first end of the lift device (5, 5′) and is designed to fix the first end of the lift device (5, 5′) with respect to the at least one rail (4a, 4b, 4′a, 4′b); and a second fixing device (7) which is connected to the second end of the lift device (5, 5′) and is designed to fix the second end of the lift device (5, 5′) with respect to the at least one rail (4a, 4b, 4′a, 4′b). The first and second fixing device (6, 7) can each be releasably fixed with respect to the at least one rail (4a, 4b, 4′a, 4′b) in a reversible manner.
Lift drive for a rail-guided cantilever construction device (2), in particular, for use in bridge construction, wherein the cantilever construction device (2) comprises a main frame (3, 3′) guided by at least one rail (4a, 4b, 4′a, 4′b) for receiving at least one formwork,
Lift drive according to any of the preceding claims, in which the first and second fixing devices (6, 7) can each be fixable with respect to the at least one rail (4a, 4b, 4′a, 4′b) by means of a positive and/or non-positive fit and can, in particular, be fastened to the rail (4a, 4b, 4′a, 4′b) and/or at least one fixing rail (40) connected to the rail.
Lift drive, according to any of the preceding claims, in which the lift device (5, 5′) is advantageously designed as a hydraulic cylinder, spindle drive or rack and pinion drive, with the spindle or rack and pinion drive being driven, for example, by an electric motor, actuator or linear drive.
Rail-guided cantilever construction device (2) comprising a lift drive, according to any of the preceding claims.
