  • the holding device is arranged above the support device, and that the spring elements extend in an upright direction between the holding device and the support device.
  • the holding device absorbs the object to be vibrated or the device to be vibrated. Due to the arrangement of the holding device above the carrying device, the carrying device does not limit the space above the holding device.
  • the device is significantly more flexible than the known device with regard to the height and width of the objects to be picked up.

  • the carrying device and holding device oscillate essentially in horizontal planes.
  • the resonant frequency of the holding device (and the objects located thereon) is used, so that the highest possible oscillation amplitude is achieved with the lowest possible expenditure of energy.
  • the holding device oscillates in a linear, translatory or rotational manner. Also combinations are possible, such as a linear oscillation in one direction and a torsional vibration in another direction. By the spring elements and torsional forces can be transmitted. By rotational movement of the support device - triggered by the drive device - may lead to a torsional vibration of the holding device relative to the support device.
  • the carrying device can be driven in a swinging manner about a central axis by the drive device. The support device then oscillates about the central axis and can transmit this vibration to the holding device.
  • the holding device oscillates about a central axis.
