<p>Provided is an elevator apparatus having a function of identifying a driving force loss determined according to a car position and a driving force loss proportional to a payload. An elevator apparatus is provided with: a car (1) coupled to a weight (2) by a rope (3); a hoist (5) for hoisting the rope; a control device (12) for controlling the drive of the hoist; and an estimation device (13) for identifying a first driving force loss dependent on a payload or a second driving force loss dependent on a car position as a numerical value model, and estimating a driving force loss from the numerical value model.</p> |
