摘要
The invention relates to a method of removing a slewing ring (3) from a pedestal-mounted crane (2). A carriage (14) is positioned on a pair of elongate guide members (9) which lie substantially parallel, both to one another and to the plane of the slewing ring (3), and which extend alongside the pedestal (14). The crane (2) is raised relative to the pedestal (4) by means of jacks (7) and the carriage (14) is moved to a position beneath the crane (2). The slewing ring (3) is then positioned on the carriage and withdrawn on the carriage from beneath the crane.
