摘要

A method of installing into a machinery hall a gas turbine unit comprising a gas generator unit and a power turbine unit and forming a portion of a large capacity, gas-turbine powered electrical generating apparatus. The method is particularly intended for electric generating equipment having a capacity of at least 60 megawatts. To install the gas generator of such a unit in the hall and to couple it to the already-installed power turbine unit, the gas generator is moved horizontally into the machinery hall on roller devices. When the gas generator has been moved horizontally to the assembly site, some of the roller devices are removed, and concurrently with their removal a portion of the load is then transferred to an overhead travelling crane in such manner that the remaining roller devices and the overhead crane provide force couples which together support the entire weight of the gas generator and also readily permit adjustments in position of the gas generator so as to bring the central shaft pivot of the gas generator into its desired position relative to a central bearing of the power turbine unit. The method makes it possible to conveniently assemble the gas turbine unit to the power turbine unit without damage to the central bearing and without any need to provide an overhead crane of a capacity adequate to support the entire weight of the gas turbine unit.
