Abstract: A shaft with a gear and a small-diameter drum mounted and a different shaft with a gear and a large-diameter drum mounted are axially mounted in a rotatable condition across the inside of a housing. The gears are engaged with each other. A case has a horizontally long cavity part being open to one side, and rope insertion holes. The cavity part has, in a movable condition, an adjusting tool between an energizing means and a restricting means. The adjusting tool has a rope insertion hole. The rope is wound around the small-diameter drum and the large-diameter drum respectively in the same direction. The externally let-off rope obtained through an upper rope let-off hole has, at an upper end, a hook. The externally let-off rope obtained through a lower rope let-off hole is in a hanging-down condition resulting from insertion of the rope into the above rope insertion holes.

Abstract: A carrier vehicle having a swing table supported on an under-carriage so as to swing a full turn, and a planetary reduction gear for reducing the revolution of a drive motor and transmitting it to the swing table. The planetary reduction gear is mounted on the under-carriage under the swing table.

Abstract: This invention concerns an improvement for the structure of a rotor attachment in a permanent magnet type synchronous motor. This invention can effectively prevent axial displacement or peeling off of the magnets which might otherwise be caused by insufficient adhesion or deterioration of adhesives by the unique structure of attaching magnets to the rotor shaft as side plates having grooves are fixed to both sides of magnets adhered to a shaft to engage with at least one end face of magnets and the outer peripheries of the side plates and the magnets are wound with non-magnetic fibers for securing, thereby greatly enhancing the reliability of the motor.
