Document Type and Number:
Japanese Patent JP7501176
Kind Code:
B2
Abstract:
To provide a mobile crane capable of transporting a load to a target position by an easy operation while understanding the situation of a work site in real time.SOLUTION: A control device 27 of a crane 1 acquires an image P including the crane 1 and the surroundings of the crane 1 photographed by a photographing device 20, and causes a display device 24 to display the image P. The control device 27 calculates turning center coordinates C which are coordinates of the turning center of a boom 9 in a coordinate system of the image P and tip coordinates B which are coordinates of the tip of the boom 9 in the coordinate system of the image P on the basis of the image P and attitude information about the boom 9. Further, the control device 27 calculates passage point coordinates T(n) which are coordinates of a passage point set on the image P and passed through by the tip of the boom 9 in the coordinate system of the image P. Then, the control device 27 controls an actuator of the crane 1 so that the tip of the boom 9 can pass through the passage point coordinates T(n) at a prescribed speed.SELECTED DRAWING: Figure 2
