The invention is directed to a remotely-operable positioning and carrier aratus for remote-handling equipment for use in large-area cells containing process components. The apparatus is mounted on a lifting device of an overhead bridge crane. The apparatus achieves good positioning of the particular remote-handling equipment even at locations which are poorly accessible. The apparatus includes a horizontal beam which is fixed at an eccentric position thereon to the bottom sheave unit of the lifting device so that the horizontal beam defines a long lever arm and a short lever arm. A receiving lever is pivotally connected to the end of the longer lever arm. The receiving lever has an equipment receiving device at its free end. A displaceable counterweight is arranged on the short lever arm for altering the position of the center of gravity of the apparatus. This apparatus makes it possible also to operate in spaces beneath components present in a rack. It is further possible for vertical forces to be applied to objects on one side in parallel relationship to the line of action of the lift cable of the lifting device. With the apparatus of the invention, it is possible to operate with a crane in areas inaccessible with the hook of the crane lifting device.

Remotely-operable positioning and carrying apparatus for remote-handling

Apparatus is described for feeding a wire from a wire coil to a processing tation. When wire is taken from a coil and fed to a processing station, because of the tension imposed on the wire, the wire end carries out uncontrolled movements which in arc welding are known as 'pig-tailing' effects. In order to obviate such uncontrolled movements of the wire after issuing from conventional guide means, in the present wire guide apparatus the wire is guided with a radius of curvature r which is equal to the radius of curvature which the cylindrical spring formed by the cylindrically wound wire has in its relaxed state. The wire guide apparatus comprises a guide tube which is joined tangentially to the coil housing and which is constructed with a slightly curved shape. Connected to the guide tube is a mouthpiece which has a curved tubular duct the radius of curvature of which is equal to the radius of curvature r. The outer diameter of the cylindrical reel on which the wire is wound is preferably greater than the inner diameter of the relaxed cylindrical spring constituted by the wound wire.
