ABSTRACT:
A balance with a weighing system protected against overloading includes a load receiving member and a weighing dish placed on the load receiving member. The weighing dish rests on dampening elements which are mounted at ends of two U-shaped levers which are supported in a central yoke. The yoke includes abutments which hold the two levers in a horizontal position in an articulated manner. When a load which is within the weighing range is applied to the weighing dish, the two levers and the yoke form a rigid unit. If an excess load is placed on the weighing dish, either dynamically or statically, the two levers are pivoted and tension a stack of springs mounted in the abutments. In addition to dampening by the pivoting of the two levers and tensioning of the stack of springs, additional dampening is effected by dampening elements between the lever ends and the weighing dish. The levers each have a cross member and stop pedestals mounted underneath the cross member conduct any excess load directly into the housing bottom or legs attached to the housing bottom.
