Abstract: Provided are examples of transportation systems, elevator systems, and kits for use in towers, as well as tower sections and methods for performing assembly or maintenance operations in towers, particularly wind turbine towers, guides mounted in tower sections for transporting an operator or robot along an inside of a tower and an elevator carrying parts of such guides.

Abstract: Provided is a stretching tensioner for tensioning a guide wire comprising: a tensioner base attachable to a lift platform, a housing located on a bottom side of the tensioner base for housing the guide wire, and a wire lock clamped on the guide wire underneath the housing and fixing the guide wire with respect to a base of the housing, wherein the housing comprises a hollow threaded shaft, an activation nut, a bearing between the hollow threaded shaft and the bottom side of the tensioner base, a tensioning nut, a resilient element arranged between the tensioning nut and the base of the housing such that upon rotation of the activation nut the tensioning nut moves axially to compress the resilient element and tensioning the guide wire, as well as wire guided lifts and wind turbines comprising such tensioners.

Abstract: Elevator systems are disclosed which comprise an elevator cabin configured to perform an up and down movement along an elevator path, and a traction wire rope for driving the elevator cabin in the up and down movement and/or a safety wire rope and may further comprises a wire guiding system including a transverse element provided above the elevator cabin in the elevator path where, the transverse element is adapted to be guided along the traction wire rope and/or safety wire rope and the wire guiding system may further comprises a pulley cable system operationally coupled to the elevator cabin and to the transverse element such that along at least a portion of the elevator path, the transverse element moves in the same direction as the elevator cabin.
