The invention relates to a wheel chocking system for at least one tire (T 2 ) of a vehicle which is rotatable on a treadway (S) between a starting position (A) and a plurality of lockable positions (B) close to a dock. The chocking system comprises:
a chocking device (10) comprising a chock (16), said chock being positionable behind said tire (T 2 ) when said rolling tire rolls on the treadway (S) from said starting position (A) to said lockable positions (B), a guide channel (C) extending along said treadway and said chocking device being moveably guided along said guide channel between an initial position and operating positions, and a controllable lock (30) capable of selectively locking said chock (16) in a chock position (B) behind the tire corresponding to any of said operating positions.
