<p>The utility model relates to the field of nuclear engineering, and more particularly to a lifting or moving device suitable for handling fuel rods or control rods, and even more particularly to a gripper drive. The differential gripper drive comprises a first cable drum, rigidly mounted on a first shaft and capable of moving a first gripper, and a second cable drum, capable of moving a second gripper. The claimed differential gripper drive additionally comprises a second shaft, on which the second cable drum is rotatably mounted, and a mechanical transmission, capable of transmitting torque between the first and second shafts. The present utility model seeks to address the problem of overcoming the disadvantages of known prior art drives, and more particularly seeks to reduce the risk of drive failure. The technical result is an increase in drive reliability.</p> |
