  • Patent number: 10035263
    Abstract: Systems and methods for a robotic system capable of carrying out operations in a hazardous or confined space. The system comprises a manipulator arm, a plinth, a trolley, an end effector, and a control system. The plinth and trolley each comprise one or more locking pawls for securing the system to mounting levels along a length of the manipulator arm. The system is capable of maneuvering between mounting points in an inch-worm-like fashion. Motion starts from a fixed position where both the trolley and plinth locking pawls are secured to a first mounting level along the length of the manipulator arm. The trolley locking pawls are then released and the trolley runs along the manipulator and secures locking pawls to a second mounting level along the length of the manipulator arm. The plinth locking pawls are then released and the plinth is drawn to the second mounting level along the length of the manipulator arm where it is secured via locking pawls.

  • Patent number: 5918861
    Abstract: A load lifting apparatus for enabling an individual user to lift a heavy weight. The load lifting apparatus includes a tricycle type base which supports a vertical beam. The vertical beam is height adjustable. The vertical beam supports a horizontal boom. The horizontal boom is capable of horizontal translational motion relative to the tip of the vertical beam. The horizontal boom has a pulley at each of its ends. A third pulley is supported by the vertical beam. A cable from a powered winch is routed around the pulleys and can have its free end attached to a load. The powered winch is attached to the vertical beam. The tricycle type base has a platform for supporting a counterweight. The powered winch can be operated under the control of the a user to draw in the cable and thus lift a load toward the horizontal boom.
