ABSTRACT:
A measuring device including a substantially horizontal shaft having a longitudinal axis and a groove defined transverse thereto. The shaft is mounted with clearance in a substantially non-circular opening defined in the lateral supports of a supporting device, the clearance being provided at least in an area opposite the groove. A bearing pin is secured to the supporting device and partially engages the groove defined in the shaft, thereby axially and non-rotatably securing the shaft to the supporting device. A load measuring element is fixedly mounted to the supporting device and supports the end of the shaft longitudinally opposite the location of the groove. The load measuring element is preferably provided with wire strain gauges or microswitches, which permit simple measurement of the load. A pulley is rotatably supported by an annular pivot bearing for rotation about the shaft to transfer the load from the shaft to the bearing pin and load measuring element. Lateral support is provided to the supporting device by support plates which are attached by a spacer at their lower ends.
