RIGGING EQUIPMENT
1. The three basic components of a wire rope are:
A. Strands, sockets and thimbles
B. Core, clips and lay
C. Wires, strands and core
D. Wires, sheaves and drum
C. Wires, strands and core
Wires are laid into strands, and strands are laid around a central core.
2. In the designation 6x19 IWRC, the number 6 refers to:
A. The number of wires in each strand
B. The design factor of the rope
C. The rope diameter in sixteenths of an inch
D. The number of strands in the rope
D. The number of strands in the rope
The first number is the strand count; the second is the nominal wire
count per strand.

3. What does the abbreviation IWRC stand for?
A. Internal Woven Rope Center
B. Inspected Wire Rope Component
C. Independent Wire Rope Core
D. Integrated Wire Reinforcement Core
C. Independent Wire Rope Core
An IWRC is a small wire rope used as the core, giving better crush
resistance than fiber.
4. Compared with a fiber core, an IWRC generally provides:
A. Greater flexibility and lower weight
B. Greater strength and better resistance to crushing and heat
C. Identical properties at lower cost
D. Lower strength but better corrosion resistance
B. Greater strength and better resistance to crushing and heat
A steel core adds roughly 7.5% strength and holds the rope's shape
under drum crushing and heat.
5. In regular lay wire rope, the wires in the strands are laid:
A. In the opposite direction to the strands in the rope
B. Parallel to the rope axis
C. Randomly to improve flexibility
D. In the same direction as the strands in the rope
A. In the opposite direction to the strands in the rope
Opposite directions make regular lay stable and easy to handle, with
good crush resistance.
6. Lang lay wire rope differs from regular lay in that:
A. It uses only fiber strands
B. It has no core
C. It is always rotation resistant
D. Wires and strands are laid in the same direction
D. Wires and strands are laid in the same direction
Same-direction lay exposes more wire length, improving abrasion and
fatigue resistance.

7. A major limitation of Lang lay rope is that it:
A. Cannot be lubricated
B. Tends to unlay unless both ends are fixed against rotation
C. Has very poor fatigue resistance
D. Is weaker than fiber rope
B. Tends to unlay unless both ends are fixed against rotation
Lang lay must be secured at both ends because it readily untwists under
load.
8. The most commonly used wire rope lay for general rigging is:
A. Left Lang lay
B. Left regular lay
C. Right regular lay
D. Alternate lay
C. Right regular lay
Right regular lay is the industry default for slings and general hoisting.
9. As the number of wires per strand increases, a wire rope becomes:
A. Unchanged in flexibility
B. More flexible but less resistant to abrasion
C. Stronger but less flexible
D. Stiffer and more abrasion resistant
B. More flexible but less resistant to abrasion
Many small wires bend easily, but thin outer wires wear through faster.
10. The correct method of measuring wire rope diameter is to measure:
A. Around the circumference and divide by two
B. Across the flats between strands
C. Only at the end fittings
D. Across the crowns of opposite strands at the widest point
D. Across the crowns of opposite strands at the widest point
Calipers placed across the strand crowns give the true diameter.

11. Rotation-resistant wire rope is designed primarily to:
A. Reduce load spinning when hoisting on a single part line
B. Increase abrasion resistance on sheaves
C. Allow a smaller drum diameter
D. Increase rope strength by 50%
A. Reduce load spinning when hoisting on a single part line
Inner and outer strands laid in opposite directions counteract torque on
single-line lifts.
12. The grade of wire rope EIPS stands for:
A. Enhanced Iron Plow Strength
B. Extra Improved Plow Steel
C. Extended Industrial Plain Steel
D. Extra Inspected Pressure Steel
B. Extra Improved Plow Steel
EIPS is a higher-strength steel grade than IPS and is the common grade
for slings.
13. A kink in wire rope:
A. Increases rope strength locally
B. Causes permanent damage and the rope section must be removed
from service
C. Only affects appearance
D. Can be straightened with a hammer and reused
B. Causes permanent damage and the rope section must be
removed from service
Once a loop is pulled tight, the strand geometry is permanently
distorted.
14. Bird caging in wire rope is most often caused by:
A. Excessive sheave size
B. Storage in a dry area
C. Over-lubrication
D. Sudden release of load or shock loading
D. Sudden release of load or shock loading
Shock unloading pushes strands outward, forming a basket shape that
requires removal.
