Generally, gas turbines are the basis of power generation facilities for producing electric energy. Recently, small gas turbines have been commercialized, and their application fields have been expanded to small power generation fields.

A micro gas turbine (MGT) power generation system is generally a power generation system using a small gas turbine of less than 300 kW, and is an engine that obtains power during compression and expansion of a gaseous working fluid.

Due to the characteristics of the gas turbine engine, the structure of the engine can be miniaturized and compacted, and utilization is increasing in all industries such as aviation, ship, and industrial.

On the other hand, heavy-weight products, such as gas turbines, must be horizontally aligned with respect to the ground during assembly of parts, and it is somewhat difficult to work with heavy weight products horizontally. There is a problem that the work time is delayed.
