Service & Spare Parts for Lohmann + Stolterfoht gearboxes
History of Lohmann + Stolterfoht
Founded in 1884 by Max Lohmann and Max Stolterfoht in Berlin. Around 1925 they started manufacturing reversing gearboxes for marine applications followed by industrial applications in 1930. During the second world war the company was almost completely destroyed, but they were able to rebuild and resume their work after the war had finished.
In 1955 they were taken over by Mannesmann AG and in 1962 the famous SPIROFLEX coupling was introduced.
The company was very succesfull, but from the year 2000 they faced a lot of takeovers and this caused the L+S legacy to be split up between a few companies. Nowadays this makes it very hard to find the right spare parts.
