What HYDRO does

HYDRO Systems GmbH & Co. KG, founded in 1965 and headquartered in Biberach, Germany, manufactures and supplies ground support equipment (GSE), airframe and engine tooling, and engine transportation solutions for the global civil and military aerospace industries. The company offers more than 3,000 GSE products — including tripod-jacks, tow-bars, axle-jacks, landing gear change equipment, engine wash systems, service carts, hydraulic power units, and ground power units — together with over 25,000 specialised airframe and engine tools covering countless aircraft and engine types. Flagship products include the COBRA universal engine change system (16.3-ton nominal capacity), the Intelligent Lifting System (ILS) recovery jack, the FortEvo N-Series tripod-jacks, and a family of engine transportation stands (Basic, Split Engine Stands, All Purpose Stands, and a dedicated PW1500 stand for the A220/PW1500G platform). The company operates a global service network of 11 service centers across the Americas, Europe, the Middle East, and Asia Pacific, supporting customers in 120 countries, with a 24/5 AOG hotline for urgent tooling needs.

HYDRO monetises through two main channels: (1) hardware sales of GSE, airframe and engine tooling, and engine transportation stands — sold on a quote-based, direct B2B model targeting airlines, MROs, and aerospace OEMs; and (2) professional services including technical consulting, loan & lease of equipment, engine stand refurbishment (as an official Rolls-Royce Engine Stand Repair licensee), asset management, tool upgrade, and OEM service. The company is organised around three product divisions (Ground Support Equipment, Airframe & Engine Tooling, and Engine Transportation) plus an Engineered Solutions division that delivers custom full-lifecycle systems from concept through manufacturing. Distribution is direct via field sales and the company website, with no public pricing and no app or API surface; marketing is led by content marketing through the hydro.aero website (including a product finder tool), downloadable brochures, and newsletters.

The company is a privately held German limited partnership (HYDRO Systems GmbH & Co. KG, with general partner HYDRO Management GmbH and Managing Directors Michael Biegert and Martin Dürr) that was acquired by US-based Rhinestahl Corporation in April 2024 to strengthen Rhinestahl's aerospace tooling and support services platform. HYDRO self-describes as the world market leader in aerospace GSE and maintenance tooling, serving both civil and military customers under a "preferred supplier" positioning reinforced by decades of installed base, OEM certifications, and qualified tooling integration.
