FAQ

Q: Are weld-on lifting lugs suitable for permanent installation on machinery?

A: Yes. Weld-on lifting lugs can serve as permanent lifting points on machinery and fabricated structures when the attachment, supporting structure and welded joint are designed for the intended lifting loads. Their suitability should be established during equipment design or engineering review.

Q: Can weld-on lifting attachments be used with chain slings and wire rope slings?

A: Compatibility depends on the attachment's geometry and the sling's connecting component. Check the available opening, contact dimensions and permitted loading direction to ensure the sling connector fits correctly without interfering with the attachment.

Q: What is the difference between a weld-on lifting lug and a lifting padeye?

A: The terms are sometimes used interchangeably in industrial lifting. However, product geometry, hole dimensions, plate thickness and design requirements can vary. Buyers should compare the actual drawing and rated capacity rather than relying on the product name alone.

Q: Can an existing weld-on lifting lug be replaced with a different model?

A: Not solely because the replacement has the same WLL. The mounting footprint, hole dimensions, plate geometry, material compatibility and weld design may differ. Review the existing installation and the proposed replacement before approving the change.

Q: Do weld-on lifting points require periodic inspection?

A: Inspection requirements depend on the applicable regulations, lifting equipment standards, operating conditions and site procedures. Inspection may need to consider deformation, cracks, corrosion, damage to the attachment and the condition of the surrounding weld and supporting structure.

Q: Can weld-on lifting attachments be used for side loading?

A: Side loading should not be assumed permissible. The allowable loading direction and capacity depend on the specific product design and its documented ratings. Confirm the manufacturer's instructions and applicable engineering requirements before using an attachment outside its intended loading direction.

Q: What information should be checked before approving a weld-on lifting attachment for a project?

A: Review the product identification, rated capacity, applicable technical documentation, material requirements, installation drawing and any required test or inspection records. The approval process should also account for the supporting structure and the completed welded connection.
