Abstract
1360950 Hooks AMERICAN HOIST & DERRICK CO 21 March 1972 [30 July 1971] 13187/72 Heading E2A A hook 10 has pivotally mounted thereon a safety gate 24 provided with a segment 26 which mates with the tip 12 of the hook and a latch 38 biassed by a spring 42 towards a locking position wherein the latch is engaged with a shoulder 36 formed in the eye 18 of the hook. The gate 24 has an eye 58 for engagement with a hoisting line 60 the axis of which is offset from the pivot axis of the hook so that when a load is placed on the hook via line 22 the latch is automatically operated. The hook is pivoted by means of a pin 32 passing through a split sleeve 34 provided in holes 30 Fig. 2 (not shown) in side plates 28 which surround the eye 18.
