Stewart Engineering & Sales Company

What Stewart Engineering & Sales Company does

Stewart Engineering & Sales Company is a family-owned custom overhead crane and hoist fabricator and distributor headquartered in Muskegon, Michigan. Founded in 1972 by Ken Stewart, P.E. after his tenure as a design engineer at Dresser Crane, the company designs and fabricates custom-engineered overhead bridge cranes (single girder and double girder) and monorail systems tailored to specific customer application requirements, in contrast to pre-manufactured kit alternatives. Its 9,000 square foot fabrication facility, in operation since fall 1996, can start up and fabricate three to six cranes concurrently, supported by two radio-controlled 7.5 ton overhead bridge cranes and Stewart wall-crane welding machines. Stewart's second generation, sons Jim (joined 1993) and Mike (joined 1996), are active in the business.

The company serves industrial and heavy-duty manufacturing customers across more than eight U.S. states via a consultative enterprise field-sales model. Its sales team consists of four graduate engineers and two Professional Engineers with over 100 years of combined experience, providing zero-cost on-site consultation and engineered solutions including runway design, fabrication, and installation. Revenue is generated through one-time sales of custom-engineered cranes and monorails, a stocked parts business (bearings, brake components, motors, controllers, safety components) across multiple OEM brands, sales of pre-owned cranes and hoists with warranty, and proprietary branded products such as the Stewart Overhead Welding Positioner and the Stewart All Purpose Dump Bucket. Stewart holds authorized distributor or strategic partner relationships with major hoist OEMs (Columbus McKinnon brands including Coffing, Shaw-Box, Yale, and Chester; Detroit Hoist; Electrolift; Harrington Hoists; GH Cranes & Components) and component suppliers (Magnetek, Duct-O-Wire, Power Electronics International, Cattron, Conductix-Wampfler), allowing it to integrate branded subcomponents into custom builds. Pricing is quote-based with multi-year project contracts; no public pricing or revenue is disclosed.
