  "abstract": "An automated trolley system for wind turbine tower segment tightening is presented. The system consists of a body with first and second portions at either end, with the first portion mounting close to bolts and driving on top of a flange while being guided by wheels, and the second portion pushing against the interior of the tower through wheels to move the body around a flange in order to automatically tighten the flange. The system includes at least one wrench socket with or without an internal pattern attached to a plate, and each wrench socket is designed to use electric or hydraulic torquing and/or tensioning to tighten each bolt that is placed on top rather than the bottom. The system comprises a winch with a balancer adapted to screwing the wrench socket with or without internal pattern.",
