Abstract: Provided herein are wind turbine tower assembly and maintenance systems and schemes. In particular, wind tower maintenance platforms are provided in order to allow service personnel to perform assembly and maintenance tasks on wind turbine towers. Some platforms disclosed herein adjust to the outer diameter of the tower, which varies tuned to the general conical shape of the tower. Other platforms provide a platform shape that allows the platform to encircle both the tower and wholly or partially encircle the turbine blade to allow personnel easy access to the blade. Other variations disclosed herein provide powerful climbing mechanisms to allow the turbine service platform to externally climb the tower carrying service personnel, parts, or even turbine blades. Gripping or braking mechanisms are provided to secure the service platform to the tower. A system is provided for lowering or raising turbine blades to and from the hub without requiring a crane.
