Lifting units consist of a vacuum pump suction device, which is connected to the suction cups by means of two or four safety circuits (for secure anchoring of sheet surfaces to the machine), and a mechanical sheet handling structure which varies from model to model: the simplest feature manual tilt and rotation, while the more complex provide powered movement.

Excellent flexibility of use means that the machines can be used to handle other materials such as fibreglass, marble and sheet metal.
