Chapter 8 Rigging Hardware
Why are the eyes in wire rope formed with pressed metal sleeves better than eyes made by using wire
rope clips? ANS -Pressed metal sleeves have a higher work strength
Name two types of clips for forming eyes in wire rope ANS -J-Bolt and U-Bolt
How many J-Bolt clips should be applied to 1" wire rope for safety? ANS -5 Bolts
Wire rope sockets are attached to wire rope by pouring molten (BLANK) inside the socket ANS -Zinc
What is the safe working load for a 1" eye hook? ANS -10,000 pounds
Since a straight pull is required when using a shackle, how is the eye or hook kept in the center of the
pin? ANS -Washers should be placed on each side to prevent shackle from moving off center
Why are only eye or jaw combinations recommended with those turnbuckles that are being used where
vibrations are present? ANS -The frame (Body) can be prevented from unthreading by securing with a
piece of wire through the frame and end attachment
(TRUE OR FALSE) It is impossible to install U-Bolts incorrectly ANS -False
(TRUE OR FALSE) Clips should be spaced every six rope diameters regardless of the type of clip ANS -True
(TRUE OR FALSE) The painting of hooks is recommended to prevent the hook from rusting ANS -False
