摘要

The lifting device (2), especially for glass panes (1), has at least one suction plate (4-7) connected to a vacuum generator via a suction line. The suction plate has at least two suction chambers (8-15), each with a suction line connected to the vacuum generator. A valve is provided for each suction chamber and in the event of a vacuum loss closes the corresponding suction line in the direction of the vacuum generator. The valve is a flow valve, and especially a spring-loaded flow valve.
