  • Publication number: 20110140060
    Abstract: A system and method are disclosed for locating a maintenance device approximate an area of interest of a wind turbine. The system generally includes a carriage configured to support the maintenance device and a cable having first and second ends attached to the carriage. Additionally, the system includes first and second anchor points, with the first anchor point being disposed adjacent to a component of the wind turbine. The second anchor point is spaced apart from the first anchor point such that the area of interest is generally disposed between the first and second anchor points. The cable may be coupled along its length between the first and second anchor points such that, as the cable is displaced, the carriage is moved to a position at which the area of interest is accessible to the maintenance device.
