A system for controlling at least two castors (1) in a castor control system (28) is provided. The castor comprises a brake activator (7) which can be used to set the castor (1) in three different positions: directional lock, neutral or braked. The brake activator (7) can be operated manually, e.g. by foot, or via a servo motor assembly (14) having a servo motor connected to the brake activator of the castor. The servo motor assembly further comprises a printed circuit board (16), a microprocessor (17) and at least one switch (19,20) connected to the brake activator (7). The servo motor assembly can further comprise a motion sensor (18). The servo motor assembly of each castor is connected to an electric brake controller (33) of the castor control system. The castors can be operated from an operating panel (37) of the castor control system (28). If the brake activator (7) of one castor is manually operated, the electric brake controller (33) can be set to let one or more of the other castors of the system assume the same position. The system can also set all castors (1) in the braked position if the motion sensor (18) detects motion of the castors (1) and the system is connected to mains voltage (40).
