Abstract

A load balance is adjusted to be appropriate even if shared loads of lifting jacks are fluctuated from an initial setting state caused by cumulative errors of suspending rods. It is a load balance adjusting method of the lifting jack when a lifting module is jacked up by the plural lifting jacks via the suspending rods. The shared loads of the lifting jacks jacking up the respective suspending rods coupled to the lifting module are detected. A height of the lifting jack is adjusted when a fluctuation relative to a setting shared load stored in advance exceeds a prescribed range, to thereby adjust to be the setting shared load.
