Abstract
An elevation apparatus is provided that initializes a calculated travel distance of a to-be-lifted object. The elevation apparatus includes a housing that has a side wall in a longitudinal direction and that has an opening in a lower face, a reel rotating to wind a reel wire, the reel wire wound on the reel to elevate the to-be-lifted object attached to a tip end of the reel wire and the to-be-lifted object is suspended from the lower side of the elevation apparatus, a controller for calculating a travel distance along which the to-be-lifted object is elevated, and a reset switch provided in the housing. The to-be-lifted object is lifted to depress the reset switch. The depression of the reset switch allows the controller to initialize the calculated travel distance.
