Abstract (en)
[origin: WO2022043514A1] The invention relates to a safety system (1) for a drive (50), which has a circulating traction mechanism (13), of a gate, in particular a lifting gate (100), more particularly a high-speed lifting gate (100), comprising a drive gear (11) and an output gear (10). A drive torque can be transmitted from the drive gear (11) to the output gear (10) by the traction mechanism (13), and the safety system (1) comprises a blocking element (15) that is not in engagement with the output gear (10) in a normal operating position, in which the traction mechanism (13) is intact, and is kept pretensioned in the normal position by means of a pretensioning device (28) and a holding device (20), wherein the holding device (20) is designed to release the blocking element (15) at least in the event of a break/tear of the traction mechanism (13), and the pretensioning device (28) moves the blocking element (15) out of the normal position and into a blocking position, in which at least the output gear (10) is blocked.
