PROBLEM TO BE SOLVED: To provide a lifting device which can maintain a position of a disposal container even if a feed material is fed.SOLUTION: A lifting device includes: a first arm; a second arm; a shaft member which supports a midship part of the first arm and a midship part of the second arm so that the arms can be relatively rotated around a second axis orthogonal to a first axis; a lower frame which supports a lower end part of the first arm and a lower end part of the second arm so that the arms can be relatively moved in a direction parallel to a third axis orthogonal of the first axis and the second axis; a first actuator which applies a force onto an intermediate part of the first arm between an upper end part and the midship part of the first arm so that a distance between the upper end part and the lower end part of the first arm in a direction parallel to the first axis can be changed; an upper frame which is supported on the upper end part of the first arm and an upper end part of the second arm, and moves in a direction parallel to the first axis in the state such that a disposal container is supported by operation of the first actuator; and a second actuator which applies a force onto at least one of the lower end part of the first arm and the lower end part of the second arm in a direction parallel to the third axis.

    【課題】供給物が供給されても処分容器の位置を維持できる昇降装置を提供する。【解決手段】昇降装置は、第1アームと、第2アームと、第1アームの中央部と第2アームの中央部とを第1軸と直交する第2軸を中心に相対回転可能に支持する軸部材と、第1アームの下端部と第2アームの下端部とを第1軸及び第2軸と直交する第3軸と平行な方向に相対移動可能に支持する下部フレームと、第1軸と平行な方向に関する第1アームの上端部と下端部との距離が変化するように第1アームの上端部と中央部との間の第1アームの中間部分に力を加える第1アクチュエータと、第1アームの上端部及び第2アームの上端部に支持され、第1アクチュエータの作動により処分容器を支持した状態で第1軸と平行な方向に移動する上部フレームと、第1アームの下端部及び第2アームの下端部の少なくとも一方に、第3軸と平行な方向に力を加える第2アクチュエータと、を備える。【選択図】図1
