Abstract

Technical activation of newly installed 3.6m optical telescope in March 20l6 paved the way for the routine operation of mechanical systems of telescope and its enclosure at Devasthal. Maintaining and upgrading complex mechanical systems for meeting upcoming technical requirements of telescope, instruments and its enclosure has been an exciting task. Few mechanical systems such as cable anti-twister, telescope cover structure, mechanical locks etc. have been indigenously designed, developed and executed while others are in the pipeline for implementation at site. Telescope’s major mechanical assemblies such as ARISS-octagon, primary mirror cell and secondary mirror cell assembly etc. were disassembled and integrated back in telescope few times for aluminizing missions and for sorting out various problems encountered in the telescope systems. It has served as an important means for training mechanical manpower in various sophisticated assemblies of telescope.
