<p>The installation (1) has two cages (2) for confining a set of animals and mounted on a central support (3) by an operating unit (5). The unit is in the form of a deformable parallelogram system that is composed of upper and lower balance forming frames (6, 7). The cages are movable between a lower loading position, in which the cages are located near the ground, and an upper work position in which the cages are remote from the ground. The support is pivotably mounted along a vertical rotational axis (3') for rotating the cages around the axis, in the upper work position of the cages.</p> |
