Abstract
To prevent toppling of a construction machine where a plurality of operating tools are provided on a single mobile platform, a control section detects the cylinder axial forces, joint angles and relative angle of rotation for a plurality of operating tools provided rotatably on a single mobile platform, and a moment calculator calculates a composite moment for the plurality of operating tools on the basis of these detection results and further calculates a stability value relating to toppling, from this composite moment and a reference moment. If the calculated stability value is less than a reference value, an anti-toppling controller issues an alarm from the alarm via an output controller and halts the operation of the plurality of operating tools, or alternatively, if the operation of the operating lever input via the lever gain calculator will cause the stability to fall below a set value, it controls a hydraulic control section such that the action of the operating tool corresponding to this operation is prohibited. By allowing the operating tool located on the base where the control section and hydraulic control section are installed to be detected by electrical signals, but …
