| 摘要 |
The present invention relates to a device for the releasable attachment of the top part of a mobile crane, excavator or suchlike machine, which top part is mounted about a perpendicular axis by means of a large rolling-contact bearing, to the bottom part of the machine, which bottom part is fixed relative to the top part. The device is to permit quick and simple release of the top part and the bottom part without substantially changing the overall height of the machine. For this purpose, a clamping connection is proposed which consists of an appropriately designed ring which is split into two halves parallel to the rotary plane, one half of the ring being fastened to the large rolling-contact bearing and the other half of the ring being fastened to the top or bottom part of the crane. Both ring halves are held together by easily releasable clamping pieces. |
