ABSTRACT:
A lock mechanism for a rotary door operator of a transit vehicle includes a lock member pivotally connected to a block cylinder and pivotally connected to a mounting bracket. Such lock member is rotatable in a locking direction to a predetermined position under a block member connected to the output shaft for preventing an axial linear movement of the door post which is connected to a door during the loss of fluid pressure. The block cylinder rotates the lock member to an unlocking position during normal operation to enable opening of the door. A lock sensing switch provides a feedback on the lock condition to the transit vehicle control system.
