WHELAN MACHINE & TOOL, LLC

Whelan Machine & Tool, LLC specializes in the precision manufacturing of overhead traveling crane, hoist, and monorail systems for defense applications. Their core capabilities center on the design, fabrication, and assembly of heavy-duty material handling equipment, with demonstrated expertise in troller assembly—a critical component in crane systems that enables precise load positioning and motion control. The company leverages advanced machining, welding, and metallurgical processes to produce robust, mission-critical components that meet stringent military performance and safety standards. Their technical proficiency includes tolerance-sensitive fabrication, structural load analysis, and integration of mechanical drive systems, ensuring reliability in high-stress operational environments. What distinguishes Whelan Machine & Tool is its focus on custom-engineered solutions for specialized defense logistics needs, emphasizing durability, precision alignment, and compliance with military-grade specifications. The contractor has delivered products exclusively to the Department of Defense, supporting defense infrastructure and logistics modernization efforts through the production of specialized material handling hardware. Their work directly contributes to the operational readiness of military installations by enabling safe and efficient movement of heavy equipment and munitions within confined or high-traffic facilities. Whelan Machine & Tool’s primary industry focus is on NAICS 333923, which encompasses the manufacture of overhead crane systems used in industrial and military settings. This places them in a niche segment of defense supply chains focused on mechanical infrastructure rather than electronics or software. Their market positioning is that of a precision fabricator serving defense logistics and facility modernization programs requiring engineered mechanical solutions. As a small business structured as a 2L entity based in Louisville, Kentucky, Whelan Machine & Tool operates with a lean, specialized workforce focused on high-value manufacturing. The company holds no formal government certifications but maintains a focused geographic presence in the Midwest, positioning itself as a regional supplier of mission-critical mechanical components to defense contractors and government facilities.
