PROBLEM TO BE SOLVED: To provide a safety device of a movable crane which is subject to preconditions of work preparation to improve the safety of the work preparation.SOLUTION: The invention relates to a safety device S of a movable crane. The safety device S includes: a remote control device 40 which is provided separately from a main operation device disposed in an operator cab, remotely operates an actuator, and is used for work preparation of the movable crane; and a control part 70 which receives instructions from the remote control device 40 and operates the actuator. The control part 70 is configured to allow the remote control operation of the actuator by the remote control device 40 only when preconditions of the work preparation of the movable crane are met.SELECTED DRAWING: Figure 2

    【課題】作業準備の前提条件を課すことで作業準備の安全性を高めた移動式クレーンの安全装置を提供する。【解決手段】移動式クレーンの安全装置Sである。そして、安全装置Sは、運転室内に配置される主操作装置とは別に設けられてアクチュエータを遠隔操作する遠隔操作装置40であって、移動式クレーンの作業準備に使用される、遠隔操作装置40と、遠隔操作装置40による指示を受けてアクチュエータを動作させる制御部70と、を備えており、制御部70は、移動式クレーンの作業準備の前提条件が満たされたときにのみ、遠隔操作装置40によるアクチュエータの遠隔操作を可能とするように構成される。【選択図】図2
