Zusammenfassung:The invention relates to a door drive device (11) for driving a door leaf (18) of a door (10), comprising a traction mechanism (13) designed in particular as a rope drive, the mechanism comprising a traction means monitoring device (28) for monitoring a breakdown of a traction means (Z1, Z2). In order to provide a simple design, which can be installed with particular ease, yet ensures safe operation, the traction means monitoring device (28) consists of mechanical blocking devices (150, 160) acting in opposing door movement directions and blocking when the traction means tension of an associated traction means (Z1, Z2) decreases and a load monitoring device (78) for a motor drive assembly (49) for load interruption when one of the blocking devices (150, 160) blocks.
