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: 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.

Abstract: A fall-arrest device test system for testing a fall-arrest device configured to be mounted around a wire rope of an elevator. The test system further comprises a loading lever having a first end arranged to rotate around a pivot between a first operational position and a second operational position, and the loading lever being operatively coupled to the wire rope, such that when the loading lever is at the first operational position the lever stretches the wire rope and when the loading lever is at the second operational position the loading lever does not stretch the wire rope. Methods for testing such a fall-arrest device are also disclosed.

Abstract: An elevator system comprising an elevator cabin, and a traction wire rope for driving the elevator cabin and/or a safety wire rope, wherein the elevator system further comprises an upper transverse element provided above the elevator cabin and adapted to be guided along the traction wire rope and/or the safety wire rope, and a support structure which is adapted to support the upper transverse element and substantially impede its movement in a downwards direction and in a horizontal direction, and to allow movement of the upper transverse element in an upwards direction.

Abstract: An elevator system is disclosed that comprises an elevator cabin guided by or around one or more substantially rigid guiding elements, a travelling cable, a pulley mounted on a pulley frame, wherein the pulley with the pulley frame is movably suspended on the travelling cable, and one or more transverse elements. The transverse element extends from a first end attached to the pulley frame to a second end configured to be slidably arranged with respect to one or more of the rigid guiding elements. The elevator system further comprises an arresting system provided at or near the second end of the transverse elements. The arresting system is configured to apply friction on the rigid guiding elements to reduce sliding of the transverse elements with respect to the rigid guiding elements when the pulley with the pulley frame is not suspended by the travelling cable.
