Emergency stop device for a rotary platform of a milking parlour

An emergency stop device for a rotary platform (1) in a milking parlour, the emergency stop device comprising:

• a component (10, 13a) arranged beside an edge portion (1a, 1b) of the platform (1);
• and
• a detecting element with a detecting area (13b1),
• wherein the detecting area (13b1) is located beside the edge portion (1a, 1b) of the platform (1) at an upstream distance (D) from said component (10, 13a) with respect to a rotary motion direction of the platform (1),
• wherein said upstream distance (D) is longer than an estimated stopping distance (d) of said edge portion (1a, 1b) when the platform (1) is emergency stopped, and
• wherein the detecting element comprises a movable unit (13b) movably arranged, in a direction substantially parallel to a direction of motion of a nearest located part of the edge portion (1a, 1b), and the detecting element initiates an emergency stop of the rotary platform (1) when an object displaces the movable unit (13b) from a first position (p1) in the direction substantially parallel to the direction of motion of the nearest located part of the edge portion (1a, 1b).
