CRANE, METHOD FOR ASSEMBLY OF CRANE AND METHOD FOR DISASSEMBLY OF CRANE Russian patent published in 2023 - IPC B66C23/34 

FIELD: cranes.

SUBSTANCE: invention relates to cranes. The crane (1) contains the first mast (10) configured to tilt relative to the support (2) of the crane around the axis (16) of rotation of the first mast to the inclined working position of the mast, and the receiving device (30) configured to receive the first mast section, a receiving device (30) configured to receive a section (11, 12, 13, 14) of the first mast (10). The receiving device (30) has a central axis (35) of the receiving device, perpendicular to the axis (16) of rotation of the first mast and parallel to the central axis (15) of the mast, and contains a guide (31) of the mast section, configured to direct the movement of the section (11, 12, 13, 14) of the mast relative to the receiving device (30) in the direction of the central axis (35) of the receiving device. The moving device (40) is configured to move the section (11, 12, 13, 14) of the first mast (10) relative to the receiving device (30) in the direction of the central axis (35) of the receiving device from the receiving position to the moving position. The locking device (50) is configured to releasably lock the position of the section (11, 12, 13, 14) of the first mast (10) relative to the receiving device (30) in the moving position. The device (60) for fixing the first mast is made with the possibility of releasably fixing the first mast (10) in the construction position of the mast.

EFFECT: efficient assembly and disassembly at an object with limited free space is achieved.
