IFAE designed the undercarriage system of the LST, which allows the telescope to rotate in azimuth. It consists of a circular rail and six wheel bogies running on top of it. It is also designed to tolerate strong vertical forces both in the downward and upward directions.

The production of the six bogies took place at different institutes belonging to the LST subconsortium (IFAE, CIEMAT, INFN Padova, MPI Munich and University of Hamburg) under IFAE’s supervision and they were later transported to IFAE for assembly. The full system is currently operative at La Palma for the LST1.
