摘要

Gripping jaws has the connecting devices comprises a permanent magnet (28) and an electromagnets (30) in such a manner that energized the connecting device. The de-energized electromagnets hold the grab means (22) by the magnetic field of the permanent magnet at the gripper jaw (18). The current feed electromagnets compensate the magnetic field of the permanent magnet for the loosening of the grab means. Independent claims are also included for the following: (1) Gripping means; and (2) Gripping device.
