Abstract: Replaceable grease injection tubes permit removal and replacement of such tubes without requiring wireline and associated tools to be removed from a well, or wireline tools to be removed from wireline and thereafter spliced or re-threaded on such wireline. Replaceable grease injection tubes include opposing semi-cylindrical members that can be joined together to form a central bore for receiving wireline and facilitating a pressure seal using injected grease or other fluid having desired pressure sealing characteristics.

Abstract: An integrated lifting apparatus for attaching a sling or other lifting means to a load having an upright and substantially hollow post. A bore is provided near the upper extent of such hollow post, extending horizontally through the hollow post. A threaded bolt having an enlarged head on one end, preferably constructed of high strength and/or shear resistant material, is disposed through the bore. A lock nut having an outer diameter greater than the diameter of said bore is threaded onto the end of the bolt. If desired, a cotter pin can also be used to secure such lock nut on the bolt.
