Lifting & Rigging Reference Hub

Baremotion’s lifting resource center. Executing critical crane operations, construction lifts, and facility material handling requires certified, load-rated gear. All overhead rigging assemblies must comply with strict OSHA and ASME engineering standards to ensure crew safety and operational compliance.

FAQ: Overhead Lifting Safety & Compliance

Q: What grade of chain is legally approved for overhead lifting?

A: According to OSHA and ASME B30.9 standards, Grade 100 and Grade 80 alloy steel chains are the only chain grades legally approved for overhead lifting applications. Standard carbon steel chains—such as Grade 70 Transport, Grade 43 High Test, and Grade 30 Proof Coil—do not possess the specific elongation, tensile strength, and impact resistance required for overhead crane lifts and should never be used.

Q: How often must overhead rigging equipment and slings be inspected?

A: ASME standards require a three-tiered inspection protocol to ensure site safety:

1. Initial Inspection: Performed by a designated person before any new, repaired, or modified rigging gear is placed into service.

2. Frequent Inspection: A visual check performed by the rigger or operator before every single shift and during use in normal operating conditions.

3. Periodic Inspection: A documented, comprehensive inspection performed by a competent professional at least once every 12 months (or more frequently if exposed to severe environments or continuous heavy duty cycles).

Q: Can a lifting sling be used if the manufacturer identification tag is missing?

A: NO. OSHA and ASME regulations strictly state that if the permanently attached manufacturer tag or stamping is missing, defaced, or completely unreadable, the lifting sling must be immediately removed from service. The tag must clearly display the manufacturer's name, the material type, the size, and the rated Working Load Limit (WLL) for specific hitch configurations (Vertical, Choker, and Basket).
