overview clamp force retention and centerring-rings for parallel grippers PGM

Our  parallel-grippers are shipped always with 6 centering rings (2 pcs for each jaw and 2 pcs for fixig the gripper itself).

Some versions are available with clamp/spreading force retention (due to construction small units have less space).
technical realisation is done via spring force. As the springs for clamp force retention are outside this option can be upgraded later on.
