Paper Abstract

The main structure is defined as the telescope mechanical structure including the drives, the encoder system, the hydrostatic bearing system and all those subsystems which make the system self standing safe and testable as an electromechanical system, with the exclusion of the velocity and position control loops. The main structure is now almost completely assembled in Milan. The tests of the main mechanical performances (dynamic and static) have been carried out to gather information at the earliest possible stage of the assembling activities. The drives and the hydrostatic bearing system have been tested concerning their functionality. This paper aims to summarize concisely the results of the tests, to compare them to the design calculations and to show some possible design changes which could improve the performances of the telescope.
