Abstract

A movable independent crane system for moving or replacing components during maintenance operations and for mounting wind generators, including an auxiliary portal crane providing a portal structure designed to be movable around a pod about a rotation shaft. The mobile independent crane system includes raising devices being part of the crane system and designed to allow self-raising of the crane system because the mobile independent crane system is anchored to the pod through an anchoring unit and because the mobile independent crane system is designed to operate over the pod and outside the pod sides.
