Embodiment Construction

[0036] In these figures, the same reference numerals are used for matching elements.

[0037] figure 1 Shown is eg a partial side view of a wind turbine tower 1 with an elevator system comprising a car 2 . The elevator system comprises a traveling cable 3 suspended at one end 31 from the elevator car 2 and at the other end 32 from a fixed point FP along the elevator shaft. The fixed point may be an attachment point to the wind turbine tower 1 or eg to a platform arranged inside the tower.

[0038] Between the elevator car 2 and the fixed point FP along the elevator shaft, the traveling cable 3 is passed around a pulley 4 (or pulley system) in order to add tension to the traveling cable. In this way, the traveling cables are always suspended during the movement of the elevator and when the elevator is still eg in the bottom parking position.

[0039] figure 2 An elevator system according to an embodiment is shown. The elevator system comprises an elevator car 2 configured...

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.

Description

technical field [0001] The present disclosure relates to elevator systems, and more particularly, to elevator systems having cables of travel. For example, configuring a service elevator system for a wind turbine tower. The present disclosure also relates to a wind turbine comprising such an elevator system. Background technique [0002] Modern wind turbines are commonly used to supply electricity to the grid. Wind turbines typically include a rotor with a rotor hub and a plurality of blades. The rotor is arranged to rotate under the influence of the wind acting on the blades. The rotation of the rotor shaft drives the generator rotor either directly ("direct drive") or through the use of a gearbox. The operation of the generator produces electricity that is fed into the grid. [0003] When maintenance work is required inside a wind turbine, hoists are often used in the form of elevator-like structures in which a lifting platform or car for the transport of personnel an...
