MASS MASS Test Rigging and Slings 3

Question 1

What is the minimum number of legs required for a rigging configuration to be self-balancing when lifting a symmetrical load?

Accepted Answer

2

Answer

Two legs allow a symmetrical load to hang in balance, provided the attachment points are equidistant from the load's center of gravity.

Question 2

Which factor is most critical when selecting a sling for a high-temperature environment?

Accepted Answer

Sling material heat resistance rating

Answer

High temperatures degrade synthetic slings rapidly, so the sling material's heat resistance rating must exceed the ambient and load temperature.

Question 3

What is the purpose of a softener or padding when using a wire rope sling on a sharp-edged load?

Accepted Answer

To prevent the sharp edge from cutting or damaging the sling

Answer

Softeners and padding protect wire rope and synthetic slings from sharp edges that can nick, cut, or crush the sling and reduce its rated capacity.

Question 4

According to ASME B30.9, how often must rigging slings receive a formal documented inspection?

Accepted Answer

At least annually or more frequently when conditions warrant

Answer

ASME B30.9 requires periodic documented inspections at least annually, with more frequent inspections based on use severity and environmental conditions.

Question 5

What does a red color code on a rigging sling typically indicate?

Accepted Answer

The sling's capacity is 3/8 inch or a specific load rating per the manufacturer's color system

Answer

Color coding on slings typically corresponds to the sling size or capacity per the manufacturer's or industry color identification system, with red commonly indicating a specific size rating.
