Abstract
The invention regards an apparatus for performing an animal related operation like milking or grooming, where the animal (9) is confined in a stall (8). In order to protect animals and equipment, it is so arranged that any breaking of the functions activates an activable state, which retracts devices (21; 10) from the region of confinement before the apparatus is allowed to finally stop.
