  • Patent number: 4789947
    Abstract: In conjunction with an unmanned, remotely controllable apparatus for inspecting, testing and viewing and for examination and evaluation of the general condition, state of repair, and of the quality of fabrication of mechanical structures including bridges, an assembly including a guide track carried by a space frame fastened to extend transversely of a bridge or other structure at an underside thereof. The track supports a carrier adapted for transporting, viewing, examining, treating and testing apparatus for controlled movement and manipulation of the apparatus along a path delineated by the guide track. In a preferred embodiment of the invention the carrier supports one or more turntables and one or more articulated arms and linked arm assemblies at remote ends of which selectable viewing and testing devices are attachable, thus facilitating physical access to and penetration into restricted mechanical zones to be viewed, examined and treated.

  • Patent number: 4552244
    Abstract: A safety support and rescue clamp for use on building structures for supporting personnel and equipment on wall faces of buildings. The clamp is characterized in that it is receivable into an elongated vertical, channel-like slotted track of the type affixed in the wall of a high-rise building. A pivotal pawl of the clamp bridges between side walls of the slot and locks rotationally within the track to serve as positive anchor means for overcoming a weight-derived, downwardly-directed force vector impressed upon a lever attached to the pawl and extending outwardly from the track.

  • Patent number: 4550376
    Abstract: Remotely controllable and manipulable unmanned apparatus for safely inspecting, testing, viewing and for non-invasive examination and evaluation of the general condition, the state of repair, and of the quality of fabrication of mechanical structures such as large buildings, chimneys and bridges. The apparatus includes a movable carrier or platform for supporting selectable scanning, testing and sensor equipment. A drive mechanism controls the movement of the platform along a predetermined inspection path to be traversed. Auxiliary electrical components and transducers are provided for transmitting intelligence and data generated by the inspection apparatus to a remote station where the intelligence is received for review, evaluation and recordation.
