Suspended load vibration preventing apparatus
 A suspended load swaying and vibration preventing apparatus for simultaneously controlling prevention of swaying of a suspended load and suppression of vibration of a structural body is provided in a container crane or the like. A trolley position and a trolley velocity are detected by a trolley position detector and a trolley detector. A swaying shift and a swaying velocity of the suspended load is detected by an image sensor. Furthermore, a shift and a velocity of a structural body is detected by a structural body vibration detector. A controller receives the detection signals from these sections, calculates the optimum trolley velocity based upon a control theory and outputs a trolley velocity command. Then, a trolley drive device is driven in accordance with the trolley velocity command from the controller. The suspended load is delivered to a desired position in a stable manner under the condition that swaying of the suspended load and the vibration of the structural body are suppressed.
