Abstract: A wind tower erection device and method for erecting wind turbine towers which avoid the need for using expensive cranes. The device and method employs a stacker unit for anchoring to the wind turbine foundation, a plurality of intermediate modules, and a mechanical actuator for raising the intermediate modules vertically. The stacker unit has a receptacle allowing for lateral sliding of intermediate modules inside of the stacker unit. In one embodiment, the stacker unit has a receptacle for lateral sliding of intermediate modules inside of the stacker unit. The stacker unit and the intermediate modules each have at least one open side to for positioning of tower sections within the stacker unit and stacked intermediate modules. A bridge crane section is initially placed on top of the stacked intermediate modules.
