Abstract
A weighing pan carrier (47) for a balance with a weighing pan and with a weighing cell that includes a load-receiving portion (11) and a stationary portion (12) has an overload protection device against excessive vertically directed forces that is releasably engaged with the weighing pan carrier. The weighing pan carrier (47) is fastened to the load-receiving portion (11) of the weighing cell and has on the other hand a fixed connection to the weighing pan. The weighing pan carrier (47) has a torque safety feature, which is integrated in the overload protection device and provides protection against excessive forces acting tangentially on the weighing pan and/or on the weighing pan carrier (47) in a direction perpendicular to the direction of the weighing load.
