ABSTRACT:
A device is proposed for the contactless grasping and holding of an object from a direction directed at least partially in the direction of the force of gravity, using a holding element situated counter to the direction of the force of gravity, at least partially above the object and at a distance from the latter, which to the greatest extent possible avoids the carrying off or migrating of particles that are possibly present. According to the present invention this is achieved in that the holding element is designed as a vibrating holding element for generating levitation waves.
