<p>An industrial vehicle such as a forklift truck includes a tiltable mast, a tilt cylinder for tilting the mast, a loading attachment mounted on the mast, a device for measuring a load weight moment in back- and- forth direction of the forklift truck. The measuring device comprises first and second pressure sensors for detecting pressures in the rod side chamber and a bottom side chamber of the tilt cylinder, respectively, and a controller for calculating axial force of the tilt cylinder by the detected pressures and for further calculating load weight moment based on the axial force calculated. The controller judges whether the forklift truck is stable based on the axial force or the moment. The measuring device further comprises a stroke end sensor for detecting a stroke end of the tilt cylinder, a load weight sensor and a height sensor for detecting load weight and height, respectively. When the stroke sensor detects that the tilt cylinder reaches its stroke end, the controller judges whether the forklift truck is stable based on the detected weight and height of the attachment. <IMAGE></p> |
