LIFTING DEVICE OF APPARATUS IN REACTOR

摘要

PROBLEM TO BE SOLVED: To provide a lifting device of an apparatus in a reactor capable of lifting and moving safely an apparatus such as a steam drier and a steam separator even in the state where a reactor well is filled with water. SOLUTION: In this lifting device of the apparatus in the reactor having a ceiling crane, a crane hook 5 hung down from the ceiling, and a winding machine suspended from the crane hook 5, the winding machine has an upper block 8 suspended from the crane hook 5; a lower block 26 suspended from the upper block 8; a plurality of winding motors 22 provided on the upper block 8; a winding drum 21 driven by the plurality of winding motors 22; a plurality of upper pulleys provided on the upper block 8; a plurality of lower pulleys provided on the lower block 26; a suspension rope hooked over the lower pulleys and the upper pulleys, whose end side is wound on the winding drum 21; an encoder 23 for detecting rotation of the plurality of winding motors 22; and a control means of the winding machine by measuring a detection value of the encoder 23.
