Device for preventing falling of wheel traveling vehicle

Abstract

Abstract PURPOSE:To enable a driver to easily recognize the falling angle in accordance with the condition of a vehicle at all times by enabling the indication of the falling angle of the vehicle in line with the change in the bending angle of a vehicle body and the change in the position of a working device. CONSTITUTION:A bending angle detector 12 for detecting the bending angle alphaof a vehicle body is installed on the junction between the front frame 3 and rear frame 2 of a wheel traveling vehicle, and an inclination angle detector 13 for detecting the right/left inclination angle beta of the vehicle body is installed on a face perpendicular to the traveling direction of the front frame 3. Displacement angle detectors 14, 15 each for detecting the up/down lift displacement angle gamma and the right/left swing displacement angle theta of the bottom 7 of a working device 4 are installed on the revolving shaft portion of the boom 7. The inclination angle of the vehicle is calculated based on the signals from each detector, to indicate the falling angle of the vehicle.
