Abstract

The present invention concerns a process and a device for carrying out the process for weight determination of the contents of containers (5), for example for garbage. Two swivel arms (2) that are lifted by hydraulic devices (3) are mounted on a garbage collecting vehicle (1). The container (5) is carried by a fork (4). Integrated into the swivel arm (2) is a force measuring apparatus that comprises two flexural members (7) supporting the main load, two spring tongues (8), and a force transducer (11) that is installed between two stilts (12) between the spring tongues (8). The flexural members (7) and the spring tongues together form an elastic stepdown; the force transducer (11) thus only measures that part of the total load flowing through it as given by the stepdown. Further, a gradient meter (16) is mounted on the swivel arm (2), that has the same action line W as the force measurement device integrated in the swivel arm (2). In this manner, the measurement of the weight of the container (5) is very extensively independent of the gradient. The weight of container (5) is calculated in known manner by two 'total weight-tare=net' weighings. In order to exclude the influences of elastic prestresses, the angle range over which it is measured is limited to a preset degree. The container (5) is inserted in the fork (4) in the position L, position M is the measuring position, and the container (5) is emptied in position E (FIG. 1).
