CHST CHST - Construction Health and Safety Technician Crane and Rigging Safety Questions and Answers 4

Question 1

What is the maximum allowable side pull angle for a standard single-part wire rope sling lift?

Accepted Answer

5 degrees

Answer

ASME B30.9 recommends keeping side pull to a minimum; crane manufacturers typically prohibit side loading beyond 5 degrees because it induces lateral boom stress.

Question 2

A synthetic web sling must be removed from service if it shows which of the following defects?

Accepted Answer

Missing or illegible load tag

Answer

ASME B30.9 requires removal from service of any sling with a missing or illegible identification tag because rated capacity cannot be verified.

Question 3

Which rigging configuration provides the highest vertical load capacity for a given sling rated capacity?

Accepted Answer

Basket hitch with both legs vertical

Answer

A basket hitch with both legs vertical doubles the effective load capacity compared to a single vertical hitch, and is more efficient than angled bridles.

Question 4

What action must be taken before working on or near a crane's electrical systems?

Accepted Answer

Apply lockout/tagout procedures

Answer

OSHA's lockout/tagout standard (29 CFR 1910.147) requires energy isolation and lockout before any maintenance on electrically powered crane systems.

Question 5

How should a tag line be used during a crane lift?

Accepted Answer

To control load rotation and swing without workers pulling against the crane

Answer

Tag lines guide load orientation and prevent uncontrolled spinning or swinging; workers must never use them to bear load weight or fight the crane.
