Articulated connection with support ball pins - has horizontal cut sections allowing easy replacement of individual parts

摘要

The support ball pin is broken down by cuts perpendicular to the longitudinal axis into several components (2,4) of low structural height compared to the overall height. These individual parts can be made, assembled and dismantled individually and can transfer the cutting forces required in the joins. A separated ball dome (4) can be placed in a ball socket (3) with connecting elements set between the ball pins (2) and ball dome. Tensile security elements (7) are formed in the area of the joins. ADVANTAGE - Extremely low structural height, esp. suitable for underground mining.
