クレーンの吊荷の可動範囲表示装置。[Scope of Claim for Utility Model Registration] A movable range display device for a suspended load of a mobile crane, which is configured to lift a load at the tip of a telescopic boom attached to a vehicle so as to be able to swing and raise freely, Telescoping boom attitude detection means for detecting the raising angle and length of the boom, rotation position detection means for detecting the rotation position of the telescoping boom, load detection means for detecting the load acting on the telescoping boom, outrigger extension/grounding status, A working state input means for inputting states such as whether or not the jib is set or whether a counterweight is present, or a working state detecting means for detecting the above-mentioned states, a CRT or liquid crystal display, and information from each of the above-mentioned detecting means and input means. A control circuit calculates a calculation based on the signal and outputs a signal for displaying the calculation result on the display, and the control circuit moves based on the signal of the telescopic boom attitude detection means. The working radius of the crane is calculated, and the calculation result is displayed on the display in polar coordinates so that the rotation around the origin is linked to the rotation of the telescopic boom, and the distance from the origin is linked to the working radius. Displaying it as a working radius image, and determining each working radius in the current suspended load state based on the signals of the telescopic boom attitude detection means, the load detection means, and the swing position detection means, and the signal of the working state input means or detection means. Calculates the load factor of the mobile crane for each turning position,
A movable range display device for a suspended load of a mobile crane, characterized in that the calculation result is displayed on the display as a load factor contour line superimposed on the actual working radius image.
