Abstract
Bei dieser Lastmesseinrichtung ist ein kleinflächiger Lastsensor (11) zwischen einer Konsole (6) und einem ersten Dämpfungskörper (12) zur Schwingungsdämpfung einer Antriebsmaschine gegenüber der Konsole (6) angeordnet. Eine von einem Maschinenfuss (5) der Antriebsmaschine ausgehende Kraft (F) setzt sich zusammen aus Kabinengewicht, Kabinenlast, Gewicht des Gegengewichtes, Gewicht der Tragmittel und Gewicht der Antriebseinheit, wobei die Gesamtkraft hälftig als Kraft (F) auf das eine Auflager (10) und hälftig auf das andere Auflager der Antriebsmaschine einwirkt. Aus dem Verhältnis der Fläche des ersten Dämpfungskörpers (12) und des Lastsensors (11) im Messbereich ergibt sich ein Kraftverhältnis der auf den Dämpfungskörper (12) einwirkenden Kraft (F) zu der auf den Lastsensor (11) einwirkenden Kraft. In this load measuring device, a small-area load sensor (11) between a console (6) and a first damping body (12) for vibration damping of a drive machine relative to the console (6) is arranged. A force (F) emanating from a machine foot (5) of the drive machine is composed of cabin weight, cabin load, weight of the counterweight, weight of the suspension means and weight of the drive unit, the total force being applied in half as force (F) to the one support (10). and acting in half on the other support of the prime mover. From the ratio of the area of the first damping body (12) and the load sensor (11) in the measuring range results in a force ratio of the force acting on the damping body (12) force (F) to the force acting on the load sensor (11).
