Abstract

A lop loaded balance with a load receiver (1, 2, 3) connected by at least one upper (11) and at least one lower guide rod in the form of a parallel guide to a system carrier (4) fixed to the housing, which load receiver, guide rods and system carrier are manufactured from one piece. The system carrier (4, 5, 6, 7) is designed as a frame. The frame-like system carrier is completely surrounded by a second frame (14, 15, 16, 17) supported on the balance feet and that both frames are constructed in a one-piece manner and are connected to one another in such a manner that twistings of the one frame are transferred as little as possible onto the other frame.
