Linnhoff and Henne

What Linnhoff and Henne does

Linnhoff & Henne GmbH & Co. KG is a family-owned German specialty machinery manufacturer founded in 1878 in Holzminden and now headquartered in Stadtoldendorf. The company designs and builds custom mastic asphalt (Gussasphalt) cookers in both horizontal and vertical stirring configurations, plus dumpers, paving screeds (Einbaubohlen), chip spreaders (Splittstreuer), silos up to 40,000 L, joint sealing and road marking cookers, self-propelled bitumen sheet laying machines, and an array of hand tools. All machines are individually engineered to customer specification - covering capacity, burner type, and mounting variant (truck, trailer, or base frame) - with no standard catalog SKUs. Approximately 40 employees work across consulting, engineering, production, spare parts, and emergency service operations, all housed under one roof at the Stadtoldendorf plant. The company is managed by Henning Stahl (Geschäftsführer) and is privately held following the 2022 ownership transition to Katharina Strümpell.

The business operates a sales-led, direct-to-customer model targeting enterprise road construction companies, bridge and tunnel contractors, and road maintenance/marking firms. Pricing is quotation-based per individual machine rather than tiered, with multi-year project contracts. Revenue derives from one-time custom machine sales, the largest dedicated spare parts warehouse in the mastic asphalt machinery segment (with same/next-day delivery for orders placed before 2 PM), repair and maintenance services for both own and third-party machines, and emergency on-site support. Distribution is primarily direct, with a regional service partner (Richard Rupprecht GmbH) covering southern Germany. Marketing relies on a multi-language website (DE/EN/RU/FR), Instagram, downloadable brochures, and personal consultation rather than broad digital campaigns.

Linnhoff & Henne self-describes as the worldwide market leader ("weltweiter Marktführer") in mastic asphalt machinery and traces its origins to the oldest continuous producer in the segment, dating to Richard Henne's 1878 coppersmith workshop. Its machines have been deployed on flagship infrastructure projects including the Hamburg Elbtunnel, the Øresund Bridge (Denmark-Sweden), and the Hong Kong-Zhuhai-Macao Bridge (~36 km). The company has no disclosed external funding, no public listing, and no disclosed revenue; it competes on engineering heritage, customization capability, parts availability, and a tightly integrated service network rather than on software or AI capabilities.
