Lightweight 100-ton aluminum body jacks — portable field-based lifting

Load Testing Services

FIELD-PROVEN. ENGINEER-APPROVED.

Precision Load Testing for Lifting Systems, Structural Assemblies, and Critical Infrastructure.

At Nordholm Companies Inc. (NCI), we understand that validating lifting capacity, structural integrity, and engineered safety is critical to modern infrastructure and marine operations. Since 1976, we’ve provided precision load testing services that meet or exceed industry and regulatory standards—from proof load testing of custom lifting tools to structural stress testing of major assemblies.

With a 300-ton pull unit, a 500-ton test frame, and combined jacking capacity up to 1,000 tons, NCI operates one of the largest independent load testing capabilities in the Pacific Northwest. Every test setup is engineered and monitored by a licensed PE with 48 years of experience, using certified load measuring devices and certified union operators. We don’t just calculate capacity—we prove it under real-world conditions.

Our Expertise

What We Do Best

hook-lift-svgrepo-com 1
Tension Pull Tests
Proof load testing for rigging hardware, spreader beams, pad eyes, pipe ends, clevises, foundations, and steel structures—validating real-world capacity under controlled, engineered conditions.
machine-press-press-svgrepo-com 1
Compression & Proof Load Tests
Applied to hydraulic jacks, bearing elements, sand jacks, and vertical load-bearing structures. Our 500-ton test frame handles the largest compression tests in the region.
welder-steel-svgrepo-com 1
Weld & Destructive Testing
Load applied to validate welds under real-world conditions, including destructive pipe pull tests to full structural failure—proving actual capacity, not just theoretical calculations.
