摘要
The present invention has: a correction means for correcting an error in the mechanical positions of a first hoisting machine and a second hoisting machine in the up-down direction; and a positioning means for positioning the first hoisting machine and the second hoisting machine relative to each other. The correction means corrects the mechanical position error before positioning is performed using the positioning means.
