Disclosed are tower erection systems and tower climbing systems and associated methods of operation. A tower erection system, in accordance with various embodiments, includes a ground-installed lifting structure, and a lifting frame configured to latch onto individual tower sections and traveling vertically inside the ground-installed lifting structure, lifted by a winch-and-cable or other lifting mechanism. Using this system, a tower may be assembled from multiple sections from the top down. A tower climbing system, in accordance with various embodiments, includes upper and lower climbers that can latch onto the lateral surface of a tower and a lifting mechanism that can move the climbers vertically relative to each other. The system can be used to carry a crane or other heavy equipment up and down along the tower. A climbing crane may be used, for example, during tower construction, or to reach the top of the tower for maintenance or repair.
