Question 2

When a shackle is used in a rigging assembly, the pin should be:

Accepted Answer

Fully tightened and moused with seizing wire

Answer

Shackle pins must be fully tightened and secured (moused) with wire or a cotter pin to prevent the pin from unscrewing under dynamic loading.

Question 3

Which sling hitch applies the GREATEST stress on a sling of a given rated capacity?

Accepted Answer

Choker hitch

Answer

A choker hitch reduces the sling's working load limit to approximately 75% of the rated capacity due to the bend and angle applied at the choke point.

Question 4

A wire rope sling shows a 'birdcage' deformation. The correct action is to:

Accepted Answer

Remove it from service immediately

Answer

A birdcage (wires or strands pushed outward) is a disqualifying condition; the sling must be removed from service immediately.

Question 5

The term 'fleet angle' in rigging refers to:

Accepted Answer

The angle between the rope and the centerline of a sheave

Fleet angle is the angle formed between the rope and the centerline of a drum or sheave; excessive fleet angle causes uneven wear and rope damage.
