Since installation of telescope in 2016 several mechanical activities have been carried out for maintaining good health of the telescope systems. Disintegration and precise integration of heavy mechanical assemblies of telescope during primary mirror aluminization in 2018 has been a major mechanical task undertaken by mechanical team of ARIES. Indigenous design, in-house manufacturing and installation of cable anti-twister for instrument cables has been carried out successfully. Mechanical support has proved vital in identification and solving of various technical problems being faced with the telescope. Maintenance in telescope mechanical systems such as compressor unit, air dryer, hydraulic group and chillers has maintained operational viability of the telescope for astronomical observations with various back end instruments. Proposed future developments involve indigenisation of mechanical systems, interfacing of upcoming backend instruments with telescope, mounting of instruments on side ports and upgradation activities for telescope enclosure. |
