Question 1

What is the primary scope of the ASME B30 series of standards?

Accepted Answer

Safety requirements for cranes, hoists, and related lifting equipment

Answer

The ASME B30 series establishes safety requirements for construction, installation, inspection, testing, maintenance, and operation of cranes, hoists, hooks, slings, and related lifting equipment.

Question 2

Per ASME B30.2, what is the minimum proof load test requirement for an overhead and gantry crane before it is initially placed into service?

Accepted Answer

125% of the rated load

Answer

ASME B30.2 requires overhead and gantry cranes to be load tested at 125% of the rated load before being placed in service to verify structural integrity.

Question 3
