## Working on now

- Industrial gearboxes and complete drive solutions for demanding applications, with emphasis on reliability, durability, customization and lifecycle service.
- European industrial-market development: Hansen/ Sumitomo exhibited at SEPEM Douai in France in January 2026 and is building channel coverage in Poland through BIBUS MENOS.
- Broader application markets include extraction/material handling, energy, environmental technology, water treatment, processing, conveyors, mixers, pumps and specialist industrial applications.
- Ongoing group collaboration and manufacturing-network development: Hansen representatives and Sumitomo Heavy Industries visited Riverside Spline & Gear in the US in July 2026 to discuss future cooperation and growth.
- The company’s current public positioning is as a Sumitomo Drive Technologies industrial-gearbox business, rather than the former standalone wind-gearbox company.

## Summary

Hansen Transmissions International nv no longer operates as an independent entity. Originally founded in 1923 as La Mécanique Générale in Antwerp, the company evolved into a leading designer and manufacturer of wind turbine and industrial gearboxes [1][2][3]. In 2011, ZF Friedrichshafen AG acquired the company, subsequently merging its wind gearbox activities into the unit now known as ZF Wind Power Antwerpen [4][3]. Separately, its industrial gearbox division was acquired by Sumitomo Drive Technologies in 2011 and operates today as Hansen Industrial Transmissions NV [2].
