To provide a vibration suppression device for a measurement device, which can direct the measurement device within a prescribed range based on a target attitude angle as a reference even when vibration is applied.SOLUTION: A vibration suppression device 30 of a suspended load camera 9b comprises: the suspended load camera 9b supported by a boom 9 so as to swing; a motor 33 for swinging the suspended load camera 9b; and a vibration control unit 36 that controls the motor 33. The vibration control unit 36 stores, in advance, information about vibration of the boom 9 when a crane device 6 is optionally operated with the weight of an optional load W and an optional attitude, estimates, upon acquisition of the attitude information of the crane device 6, the weight of the load W, and an operation signal of the crane device 6, the vibration of the boom 9 from the attitude information and the operation signal on the basis of the vibration information, calculates an estimated disturbance torque d applied to the suspended load camera 9b through the estimated vibration of the boom 9, and controls the motor 33 so as to cancel the calculated estimated disturbance torque d.SELECTED DRAWING: Figure 5

    【課題】振動が加わっても計測装置を、目標姿勢角を基準とする所定の範囲内に向けることができる計測装置の振動抑制装置を提供する。【解決手段】吊り荷カメラ9bの振動抑制装置30であって、ブーム9に揺動自在に支持される吊り荷カメラ9bと、吊り荷カメラ9bを揺動させるモータ33と、モータ33を制御する振動制御部36と、を備え、振動制御部36は、クレーン装置6が任意の荷物Wの重量および任意の姿勢において任意の操作がされた際のブーム9の振動に関する情報を予め保持し、クレーン装置6の姿勢情報、荷物Wの重量およびクレーン装置6の操作信号を取得すると、前記振動情報に基づいて、前記姿勢情報と前記操作信号とからブーム9の振動を推定し、推定した前記ブーム9の振動によって吊り荷カメラ9bに加わる推定外乱トルクdを算出し、算出した推定外乱トルクdを打ち消すようにモータ33を制御する。【選択図】図5
