Frequently Asked Questions

Grade 100 alloy chain offers approximately 25% more lifting capacity than Grade 80 chain in the same size. Both grades are fabricated, proof tested, and certified on-site at Columbia Rigging. Distinctive chain colors help crews quickly identify the grade and lifting capacity during rigging operations.

Pro-Edge slings use double-ply construction with high-tenacity yarns and edges made from twisted tire-cord yarns. The webbing is impregnated with binders that enhance abrasion resistance. This construction extends service life in industrial lifting applications where edge wear typically causes failure.

Columbia Rigging uses a 200,000 lb capacity Esco proof test machine calibrated to N.I.S.T. standards. Testing is performed on-site in accordance with ASME and ANSI requirements. This capacity handles most industrial sling and rigging hardware certification needs for construction and manufacturing operations.

Synthetic slings reduce surface damage on finished materials, machinery, and painted surfaces while maintaining lifting strength. They're lighter and easier to handle than chain or wire rope. Use them when protecting the load matters as much as lifting capacity — manufacturing, equipment moves, and finished product handling.

Shortening pockets let you adjust sling length without removing legs or using additional hardware. This improves rigging efficiency when lifting loads at different heights or configurations. Every leg on Columbia Rigging's alloy chain slings includes shortening pockets for field adjustments.

Columbia Rigging supplies domestic rigging hardware from Crosby, Columbus McKinnon, Skookum, Van Beest, Landmann Wire Rope Products, and Ulven Forging. Swivel hoist rings come from Actek Manufacturing. Dynamometers for load monitoring are supplied by Eilon Engineering Weighing Systems.

Wireless dynamometers monitor load weight in real-time during crane picks and rigging operations without physical connection to the load cell. They verify capacity limits, prevent overloading, and document lifting weights for compliance records. Useful in construction, fabrication shops, and transportation where lift verification matters.

Wire rope comes in bright finish, galvanized, stainless steel, and vinyl-coated options. Rotation resistant rope works for crane operations where twisting creates problems. Galvanized aircraft cable suits marine and outdoor applications. Multiple diameters and strengths support lifting, towing, and industrial equipment installations.

Synthetic slings manufactured by Slingmax and other recognized brands are available up to 500,000 lb capacity. Twin-Path slings offer high-performance lifting for oversized loads in manufacturing and construction. Round slings distribute load pressure across a wider surface area than flat web.

Binder chains, ratchet straps, winch straps, and load binders secure cargo during transport. Flat hook, wire hook, V-ring, and chain extensions handle different trailer configurations. Weld-on D-rings and corner protectors customize commercial trailers for agricultural, construction, and industrial hauling throughout the region.

ASME and ANSI standards require periodic inspection and proof testing of lifting equipment. Certification documents verify that slings and rigging hardware meet load ratings and safety requirements. This documentation supports compliance during inspections and reduces liability when lifting operations are reviewed.

Manual chain and lever hoists don't require electrical power, making them ideal for remote locations, maintenance work, and environments where electricity isn't available. They're portable, reliable, and give precise control for positioning heavy equipment in fabrication shops, warehouses, and construction sites.
