Abstract
An indicating method and apparatus of cargo load condition of a forklift truck. In this method and apparatus weight and centroid position of the loaded cargo are calculated by a calculation control circuit based on loads applied to a lift mechanism and a tilt mechanism of the truck. The calculated weight and centroid position are displayed on two-dimensional coordinates illustrated on a displaying device in contrast with an overturn danger line which is determined forecasting the forward overturn of the truck. The load condition may be displayed in three-dimensional coordinates in relation to lift height of the cargo as well as the weight and the centroid position thereof.
