What Stinar does

Stinar is a U.S.-based manufacturer of aviation ground support equipment (GSE), founded in 1946 and currently headquartered in Blooming Prairie, Minnesota. The company designs and builds passenger boarding stairs, lavatory service trucks and carts, potable water trucks and carts, maintenance high-lift trucks, specialty vehicles, and (as of 2024) a Limited Mobility Lift for passengers with reduced mobility. Its products are constructed on OEM chassis (Ford F550, RAM 5500) and incorporate proprietary hydraulic scissor-lift mechanisms, PTO-driven hydraulic pumps with backup power packs, four-corner hydraulic stabilizers rated for 70 mph winds, and stainless steel tank fabrication. Stinar markets an industry-leading 3-year warranty on manufactured parts and supports equipment throughout its lifecycle via in-stock parts, refurbishment services, and documented units operating beyond 35 years.

The company operates a direct, sales-led go-to-market model. Pricing is quote-based with no public list prices; financing up to $450,000 over 72 months is offered through a partnership with KLC Financial, and rental/leasing options are available through Mercury GSE. Customer segments include U.S. government and military (approximately 90% of business per disclosed sources, including supply of presidential stairs for Air Force One), commercial airlines, fixed-base operators (FBOs), third-party ground handlers, and airport operators. Marketing channels center on major aviation trade shows (NBAA-BACE, GSE Expo), editorial coverage in Ground Handling International magazine, the company website, and CEO-authored monthly bulletins. Average equipment lead time is 6-8 weeks.

Stinar was acquired out of bankruptcy by Craig Kruckeberg in 2018-2019 and operates as a subsidiary of Kruckeberg Industries. Under new management, manufacturing relocated from Eagan to Blooming Prairie, Minnesota, and a leadership team was assembled including Jeff McCabe (VP Sales and Operations, focused on defense/military relationships) and Amy Hinzmann (CFO/COO of the parent). The company tripled production capacity in 2023, expanded manufacturing footprint (an additional 65,000 sq ft at 500 Minimizer Way), and has introduced multiple new products — the Stagecoach passenger transport cart (2023) and the Limited Mobility Lift (2024, upgraded 2025) — while adding rental/leasing and financing channels to broaden customer reach.
