The joint (10) e.g. roller rotary joint (12), has upper and under carriages connected with each other via a quick-release coupling, and a set of hydraulic drive units (14) connected with each other and arranged on the joint. The quick-release coupling includes two circular opposed webs (16, 18) and bolts (20) that are pluggably received around a periphery of the joint to provide a bolt connection with a mounting flange of the undercarriage or the upper carriage to be received between the webs. The bolt connection is provided with a mounting flange to be received between the webs. |
