<p>A segmented elevator link (11) is shown of the kind used to support a derrick elevator from a derrick hook. The elevator link has two or more shank portions (15, 22) having ends which are joined together by a split collar. The shank ends are upset, being joined to the shanks at tapered surfaces which correspond to matching tapers (63, 65) in an interior bore of the split collar which releasably engages the link ends. A plurality of bolts passing through aligned bores (51) in the split collar and link ends wedge the ends together and serve to maintain the link eyelets in alignment.</p> |
