Abstract

PURPOSE:To intuitively grasp an actually operating attitude by displaying a picture, which shows an actual turn table direction and work radius displayed on a display, to be always directed toward the upper of the display. CONSTITUTION:A control circuit 11 inputs signals of a telescopic boom attitude detecting means 7, turn direction detecting means 8 and a load detecting means 9, and a rated work radius 12, turn table turn direction (direction of telescopic boom) and an actual work radius (full line) are obtained and displayed on a polar coordinate of a display 10. Here a picture 13, which shows the turn direction and the actual work radius, is displayed always to be faced to the upper of the display 10, and the rated work radius picture 12 is turned in a reverse direction to turning of a turn table. Thus by intuitively graspably displaying a relation between a picture on the display and the actual operational attitude of a crawler crane, misunderstanding or the like can be prevented.

In FIG. 3, the control circuit 11 performs calculations over a predetermined rotation range of the swivel platform 3 for the load actually being lifted by the self-propelled crane 1, and displays the calculation results on the display 10 in a pole position table. The rated working radius calculation section 11a, which outputs a signal for the operation, calculates the actual working radius based on the signal from the telescopic boom attitude detection means 7, and displays the calculation results on the pole position table displayed on the display 10. The actual working radius is displayed as the distance from the origin of the polar coordinates, and outputs a signal to display an image indicating the rotation direction of the swivel platform 3 (the direction in which the telescopic boom 2 is pointing) at a position above the origin. It is composed of a calculation section 11b and a display image rotation circuit 11c interposed in a signal transmission path for transmitting the output signal of the rated working radius calculation section +1a to the display 10. The display image rotation circuit 11c rotates the display 1 based on a signal from the rotation direction detection means 8.
