Lift drive for a rail-guided cantilever construction device

A lift drive for a rail-guided cantilever construction device, the cantilever construction device comprising a main frame guided by at least one rail for receiving at least one formwork, the main frame being configured to move, along the at least one rail, horizontally forward in a first direction or horizontally backward in a second direction opposite the first direction, comprising:

• a lift device, wherein a first end of the lift device is configured to be connected to the main frame, and a second end of the lift device opposite the first end is movable relative to the main frame when the first end of the lift device is connected to the main frame;
• a first fixing device connected to the first end of the lift device and configured to fix the first end of the lift device with respect to the at least one rail;
• and
• a second fixing device connected to the second end of the lift device and configured to fix the second end of the lift device with respect to the at least one rail, wherein the first and second fixing devices can each be releasably fixed with respect to the at least one rail in a reversible manner,
• wherein the lift device is configured to be fixed or attached by the first fixing device and/or the second fixing device with respect to the at least one rail, and, when the rail-guided cantilever construction device is connected to the first end of the lift device, the rail-guided cantilever construction device is safely movable in a direction of travel while independent movement of the rail-guided cantilever construction device in or against the direction of travel is prevented.
