Abstract
A marine crane having an upper works rotatably mounted on a pedestal adapter, includes a retainer for limiting the extent to which the upper works can be tilted, such retainer having an arcuate member secured to the upper works that extends partially around the pedestal adapter and presents a lip beneath and out of contact with a stationary circumferential member forming a part of the pedestal adapter. The arcuate member has a series of vertical, plate-like buttresses spaced along its circumferential length that have outer ends facing a machinery deck of the upper works to brace the arcuate member, so as to retain the arcuate member in place in the event of abnormal forces being applied thereto.
