Abstract

The disclosure features lifting apparatuses for building cylinders in machines for producing 3D components. The apparatuses include a first bracket that receives the building cylinder, a first guide body that controls the first bracket movably and moves the building cylinder into a working plane in a process chamber, and a main drive that controls a piston that can be coupled to a substrate plate of the building cylinder with a stroke movement. At least one further guide body is associated with the first guide body, and both guide bodies are movable on at least one guide. The additional guide body has a bracket on which the main drive is provided, and the first and additional guide bodies have at least one driving apparatus to move them successively along the guide.
