Herrenknecht AG is a German company that manufactures tunnel boring machines (TBMs). Headquartered in Allmannsweier, Schwanau, Baden-Württemberg, it is the worldwide market leader for heavy TBMs.
Established by Martin Herrenknecht in 1975, the company soon grew. Its first overseas subsidiary, Herrenknecht International Ltd, was created in 1984; a further 79 subsidiaries would be set up or purchased over the next 30 years to provide global coverage. Its products have often pushed technological boundaries; a Herrenknecht-built TBM in the late 1990s was the largest in the world at that time, while the world's longest and deepest railway tunnel (the Gotthard Base Tunnel) was bored using the company's apparatus. By 2015, the company had around 5,000 employees.
