Abstract

The device (10) for determining a weight of a load in a working vehicle has a link device (12) including an upper link member (16), a lower link member (17) and a load holder (15) that moves the load up and down by means of a hydraulic cylinder (21) so that a height of the load is variable or adjustable, a pressure sensor for generating a pressure signal depending on the hydraulic pressure in the hydraulic cylinder (21) and a position sensor for generating a position signal depending on the position of the link device relative to the working vehicle. From the signals of both sensors and also, optionally, signals from a pitch sensor measuring the pitch angle of the working vehicle, a processor (26) determines the size of the suspended load (11) and its weight change, since it determines measured values sets for three unknown variables, weight (G) and center of gravity position (r.sub.SP, .alpha..sub.SP), advantageously in at least three different measurement configurations or positions of the link device (12). The weight (G) and its change may be determined in the traveling working vehicle.
