Heavy-Duty Alloy Chain Slings Fabricated and Tested in Pasco

When you need alloy chain slings fabricated to exact specifications in Pasco, WA, Columbia Rigging Corporation builds, proof load tests, and certifies them on-site using a 200,000 lb test machine calibrated to N.I.S.T. standards. Every sling meets ASME and ANSI safety requirements before leaving the facility. This means your crew receives rigging equipment verified for strength and safety, not just tagged and shipped.

How Are Alloy Chain Slings Built On-Site?

Each sling is assembled in the Pasco shop using Grade 80 or Grade 100 alloy chain, fittings, and hardware selected for your lifting application.

The fabrication process includes welding master links, attaching hooks or shackles, and configuring leg lengths to match your specifications. Built-in shortening pockets let your crew adjust working lengths quickly without changing the entire assembly. Grade 100 chain provides approximately 25 percent more lifting capacity than Grade 80 for the same chain size, which can reduce rigging weight and improve handling efficiency on heavy lifts.

After assembly, every sling undergoes proof load testing on Columbia Rigging's calibrated machine to verify it can safely handle rated loads. This step ensures that the components work together under real stress before the sling reaches your job site.

What Makes Grade 100 Chain Different?

Grade 100 alloy chain delivers higher working load limits in the same physical size as Grade 80 chain due to improved metallurgy and heat treatment.

If you're searching for rigging solutions near me, you'll find that the capacity increase allows your team to lift heavier loads without stepping up to a larger, bulkier chain size. Distinctive color coding helps crews quickly identify chain grades on the job, reducing the risk of using an undersized sling. Reduced fittings simplify the rigging path and cut down on connection points that can complicate setups during crane operations or fabrication work.

Columbia Rigging stocks both grades and can recommend the best option based on your lift plan, frequency of use, and operating environment across Eastern Washington.

Which Industries Rely on Custom Chain Slings?

Heavy construction, transportation, manufacturing, and agricultural operations throughout the Tri-Cities area depend on certified alloy chain slings for safe lifting.

Fabrication shops use them to move steel beams, pressure vessels, and machined components during assembly. Transportation companies rig oversized cargo for flatbed and heavy-haul shipments. Agricultural facilities lift grain equipment, irrigation systems, and processing machinery during installation and maintenance cycles.

Municipal crews working on infrastructure projects rely on proof-tested slings for bridge work, utility installation, and equipment relocation. Each industry benefits from slings configured to exact load requirements and verified through documented testing protocols.

Do Eastern Washington Job Sites Require Certified Load Testing?

Many commercial contracts and safety programs mandate proof load testing and certification documentation before rigging equipment goes into service on a job site.

Eastern Washington's industrial and construction sectors often work under strict safety standards that require traceability for every lifting component. Columbia Rigging's on-site testing and certification process produces documentation that satisfies OSHA, project engineers, and insurance requirements. The calibrated test machine delivers consistent, repeatable results that give project managers and safety officers confidence in equipment performance.

Because testing happens in Pasco, turnaround times stay shorter than sending slings out of state for third-party certification.
