Safe assembly and installation of a flywheel

A flywheel device, comprising:

• a rotor for storing energy, the rotor comprising a primary rotational mass having a top surface and a bottom surface;
• a shaft coupled to the rotor, the primary rotational mass of the rotor configured to rotate around a central axis of the shaft;
• a housing enclosing the rotor, the housing including a top plate, a bottom plate, and a side wall, the housing defining a hole aligned with the central axis of the shaft;
• a bearing housing substantially filling the hole aligned with the center axis of the rotor, the bearing housing including a bearing coupled to the shaft;
• a plurality of posts configured to physically contact the bottom surface of the primary rotational mass of the rotor during transport of the flywheel assembly to prevent motion of the rotor during transport of the flywheel assembly, the plurality of posts fixedly attached to the housing;
• and
• a lifting mechanism configured to lift the bearing housing during installation, from a transport position at which the rotor rests on the plurality of posts, such that the rotor is lifted off the plurality of posts enabling the primary rotational mass to rotate around the central axis.
