ABSTRACT:
A method for determining the weight of a load upon a load support of a hydraulic lifting device, in which the pressure of hydraulic fluid within a lifting cylinder is measured and a stored reference curve representing the relationship between the weight of the load and the hydraulic fluid pressure is determined by multiple measurements of the pressure resulting from loads of known weight and the reference curve. According to the method, the load support is lifted and lowered during a short period upon operator request or automatically to sense the load before and during load lifting and lowering operations and a plurality of pressure measuring values are obtained. A pair of average values of the pressure measuring values for respectively lifting and lowering is generated, as well as a third average value of the pair of average values. The third average value is then applied to the reference curve for determining the weight of the load.
