Abstract
A system for repairing dents in a wind turbine tower section may generally include a dent repair tool having a tool hub and a plurality of arms configured to extend radially outwardly from the tool hub towards an inner surface of the tower section. The tool may also include a linear actuator configured to linearly actuate a plunger of the actuator arm relative to the tool hub such that the plunger applies a radially outward force against the inner surface of the tower section at or adjacent to a location of a dent formed in the tower section. In addition, the system may include a load sensor configured to provide an indication of a load associated with the radially outward force applied against the inner surface of the tower section by the plunger and a controller configured to monitor the load based on signals received from the load sensor.
