<p>The device has individual stations (P1-P3) comprising an upper element (10), a lower element (12), a balancing bar (14) and a bar (16). The bar is placed such that a passage space (E) for a head of an animal is delimited between the balancing bar and the bar. The balancing bar adopts release and obstacle positions by pivoting the balancing bar around a balancing axis (A14) at middle height between the upper and lower elements. The bar pivots around a bar axis (A16) to adopt two positions that define two width (L) of the space in the release and obstacle positions of the balancing beam.</p> |
