LIFTING SYSTEM AND METHOD FOR OPERATION OF LIFTING SYSTEM Russian patent published in 2022 - IPC E04G21/32 E04G3/28 E04G11/28 

FIELD: construction.

SUBSTANCE: invention relates to lifting system (100, 110), in particular to a self-lifting formwork system containing at least one lifting rail (10), which is guided along at least two lifting shoes (38), wherein lifting shoes (38) can be fixed on and/or in section (50) of cured concrete, and at the same time lifting shoes (30) are made with the possibility of guiding lifting rail (10) and/or holding it at least relatively to lifting direction (K), and actuator (16). Lifting system (100, 110), in particular the self-lifting formwork system, contains at least one lifting rail (10) directed along at least two lifting shoes (38), while there is a possibility of attachment of lifting shoes (38) to and/or in section (50) of cured concrete, and lifting shoes (38) are made with the possibility of guiding lifting rail (10) and at least holding the specified lifting rail relatively to lifting direction (K), and actuator (16). In this case, at least one lifting rail (10) contains at least one first and one second part (12, 14) of the rail, wherein first and second parts (12, 14) of the rail are located one after the other, when viewed in lifting direction (K), so that each first and second part (12, 14) of the rail can be guided and held by means of one of lifting shoes (38), while actuator (16) is made with the possibility of increasing distance (d) between first and second parts (12, 14) of the rail along lifting direction (K), if necessary, to push first part (14) of the rail away from second part (12) of the rail, using which actuator (16) rests on lifting shoe (38), or reducing distance (d) between first and second parts (12, 14) of the rail along lifting direction (K), if necessary, to lift second part (14) of the rail along lifting direction (K), while first part (12) of the rail is held in lifting shoe (38) intended for it. A method for operation of such a lifting system is also described.

EFFECT: creation of a new lifting principle for lifting systems (100, 110) and, thus, a possibility of continuous lifting along section (50) of cured concrete.
