Device used as a safety device for the drive of a rake blade on the nose of an armored vehicle comprises a path sensor (13) scanning a groove (11) extending over the ball (10) of a tilting bearing (4) and determining the possible rotation of the ball when the groove rotates in its position relative to the sensor. The sensor actuates a switch which switches off the blade drive according to the groove scanning. Preferred Features: The ball of the tilting bearing is fixed on a bearing bolt (8) forming the bearing of the rake blade and the groove runs on the ball radially to the bolt axis. |
