The document describes a process for fitting and inspecting runner hydro Francis blades and fittings weighing 320 tons for the Belo Monte Project using a laser tracker. Key steps include: creating a 3D software model of the blade positions to mark on the crown; aligning the crown with the model to mark points ensuring proper blade positioning; identifying points to ease assembly; developing and executing a program concept with operators; and assembling while adjusting to ensure fast, easy, and reliable installation verified by a final report without need for templates or double checking before welding.
