Gresham, Oregon Patent of the Year – 2024/2025
Columbia Steel Casting Co. Inc. has been awarded the 2024/2025 Patent of the Year for mechanical innovation. Their invention, detailed in U.S. Patent No. 5956936, titled ‘Elongated chain link’, introduces a redesigned chain link that increases strength and improves wear resistance in high-stress industrial applications.
This new chain link design addresses the common problem of early failure in heavy-duty conveyor systems. Its elongated shape and reinforced structure distribute stress more evenly and reduce weak points.
By minimizing sharp bends and improving alignment between links, the invention reduces friction and extends the lifespan of the chain system. This means less downtime, lower maintenance costs, and improved operational efficiency.
The elongated chain link is ideal for use in mining, construction, and other heavy industries where traditional chain links often fail under extreme load or abrasion.
Columbia Steel Casting Co. Inc. continues to advance industrial engineering with durable, high-performance solutions that solve real-world challenges. This patent reflects their long-standing commitment to innovation and reliability.
