To estimate the state related to a hoist without constructing a physical model.SOLUTION: A hoist comprises a motor and winds up/down a suspended load by controlling the motor. The hoist has an operation information acquisition part to acquire motor operation information and a state estimation part to estimate the state related to the hoist based on operation information acquired by the operation information acquisition part and on a state estimation formula which has been learned to be able to estimate the state related to the hoist. The state estimation formula consists of a common estimation part independent of a hoist model, and of a model-specific estimation part differentiated for each model of the hoist.SELECTED DRAWING: Figure 5

    【課題】 物理モデルの構築なしに、巻上機に係る状態を推定する。【解決手段】 モータを備え、モータを制御して吊荷の巻上げおよび巻下げを行う巻上機であって、モータの運転情報を取得する運転情報取得部と、運転情報取得部により取得された運転情報と、巻上機に係る状態を推定可能に学習されている状態推定式とに基づいて、巻上機に係る状態を推定する状態推定部とを有し、状態推定式は、巻上機の機種によらない共通推定部と、巻上機の機種ごとに異なる機種固有推定部とから構成される巻上機。【選択図】図5
