Abstract
A lifting spindle arrangement is disclosed for a retractable thruster unit of a marine vessel, the lifting spindle having a lower end and an upper end and being supported at its lower end to a lower support structure by a lower support assembly and at its upper end to an upper support structure by an upper support assembly. The lifting spindle is provided at its both ends with a locking member for such a connection to the support structures such that each end of the lifting spindle may freely move in an axial direction away from the opposite end of the lifting spindle.
