Abstract

A balance with a load changing device (14) that has a magazine table, mounted to be horizontally movable and having a plurality of vertical openings (26) arranged in groups. The balance (12) has a load cell (34) and a load receptor (42) with a carrier arrangement (44) corresponding to each of the groups of openings. The magazine table and the balance are height adjustable relative to each other. In a weighing position, a group of openings above the load receptor is penetrated by the carrier arrangement. In a changing position, the carrier arrangement is positioned lower than the openings in the magazine table. The magazine table is mounted at a fixed height relative to a base (16), and the balance is height adjustable relative to the base. The travel of the balance is upwardly limited by a stop (32), which is at a fixed height relative to the base.
