Systems are provided for a blade installation tool. The blade installation tool may include a vertical guide having a vertical ram path. A ram may be disposed along the vertical guide. The ram can move along the vertical ram path between a lower position and an upper position at a height above the lower position. Gravity may drive the ram from the upper position toward the lower position to provide an impact force of the ram against a blade segment of a turbine or a compressor. The height of the upper position is variable so as to control the impact force.
