Stall for breeding livestock e.g. pig, has guiding unit limiting movement of roller between two positions, where point of application of rotation force moves away from axle when access door moves from closed position to open position
The stall (1) has an access door (2) movable between open and closed positions and rotating around an axle (3). A roller (10) exerts a rotation force on the door. A guiding unit (13) limits the movement of the roller between two positions (11,12) close to and away from the axle, respectively. A point of application of the force moves away from the axle during the passage of the door from the closed to the open position.
