Abstract
A formwork system for prefabricated concrete parts has a baseplate (1) on which is mounted a magnet element (2A) which holds formwork or attachment elements in their positions. In order to enable such formwork or attachment elements to be handled more easily, they are equipped with a lifting frame (14) which overlies the magnet element (2A) and, on the side of the magnet element (2A) facing away from the baseplate (1), there is a gap (19) between the magnet element (2A) and the lifting frame (14). A suitably designed spring device (25) in the lifting mechanism can be used, after zeroing, to enable lifting to be carried out automatically.
