• Side loading: Swivel will turn freely in one spot and
lock-up in another. This condition can also be
checked by looking at the gap (see Figure 5-31
)
between barrel and shank (swivel must be removed
from weight ball to check). If the gap is wide on the
side and closed on the other, damage is present.
NOTE: The gap between barrel and shank is normally
0.020 to 0.050 inches. If the gap increases, swivel-
bearing failure is indicated.
8. Check the load block for signs of overloading: spread
side plates, elongated holes, bent or elongated tie-bolts,
and cracks.
9. Check all welds for defects and cracks.
10. Check the wire rope for wear and broken wires at the
point the wire rope enters the dead-end socket. Check
the socket for cracks. Tighten the wire-rope clips at the
dead end of the wire rope.
11. Check that each hook has a hook latch and that the hook
latch operates properly. Latch must not be wired open
or removed.
