摘要：
A load detector for an elevator having a cage moving up and down in a shaft for transporting passengers and a cable hanging the cage, including a relative position detector configured to detect a relative position of the cage against the shaft; and a calculator configured to calculate a change of the relative position between the position of the cage just after landing at a floor and the position of the cage just before leaving the floor, and a load of the cage on the basis of the change of the relative position caused by an expansion and contraction of the cable.
