ABSTRACT:
Moisting apparatus for assembling and operating a nuclear reactor comprises two rope drums, two gear mechanisms, and two hoisting mechanisms each with one rope for a predetermined load, a change-speed gear mechanism or shiftable gear mechanism for the selectable adjustment of various hoisting speeds for the two hoisting mechanisms, a drive connection which is provided for at least one gear mechanism and permits different distances between the said gear mechanism and the change-speed gear mechanism, a common motor for the two hoisting mechanisms, a rigid connection for the two lifting mechanisms which permits different distances between the lifting mechanisms, and a rope compensating device selectively adjustable so as to be operative or inoperative.
