发明名称 Chain grab hook providing for a flat lay cross-over link
摘要 A chain grab hook (10) which engages the cross-over link (30) in a generally flat lay or generally horizontal position is disclosed. The free-end portion (14) of the grab hook (10) includes a support surface (40) which supports the flat face of the cross-over link (30) over a substantial length of the link and over a substantial surface area. The tip (48) of the free-end portion (14) of the hook (10) projects inwardly to provide an obstruction which tends to prevent accidental chain slide-out. The support surface (40) may be slightly angled relative to the horizontal to cause the side links (32, 36) to rotate toward the neutral fiber center (26) of the hook (10) to reduce the moment arm applied by the loaded chain on the hook.
