  • Patent number: 8650675
    Abstract: A suspended patient-carrier/transport apparatus of the type including an overhead rail forming a horizontal track terminating at a track-end, and a carrier device supported by a carriage having a plurality of aligned rollers rideable along the track. The inventive suspended transport apparatus has a locking safety mechanism including a track-end detector and a locking device. The locking device is operatively connected with respect to the track-end detector which actuates the locking device to engage the rail thereby stopping the carriage on the track upon sensing an absence of the track beyond the track-end.

  • Patent number: 8296878
    Abstract: A suspended patient-carrier/transport apparatus of the type including an overhead rail forming a horizontal track terminating at a track-end, and a carrier device supported by a carriage having a plurality of aligned rollers rideable along the track. The inventive suspended transport apparatus has a locking safety mechanism including the carriage having a main carriage portion and a forward carriage portion. A track-end detector is at the forward carriage portion and movably secured with respect thereto such that the track-end detector moves downwardly when it runs beyond the track-end. A locking device is operatively connected with respect to the track-end detector such that downward movement thereof causes the locking device to engage the rail thereby stopping the carriage on the track.
