Abstract: The wheel loading balance has a platform (1), of which one side (13) is, by a first pair of tibs (2), supported for horizontal movement on a first lever member (4) while the opposite side (14) is supported for horizontal movement on a second lever member (5) by a second pair of ribs (3). The two lever members (4, 5) are connected to each other pivotally and in such a way as to be secured against mutual displacement by a spring steel plate (33), being rotatably and horizontally movably mounted in a base (6) (38 to 41) at their remote ends (36, 37). One of the two facing ends of the lever members is rigidly connected to a pressure transmitting member (7) while the other is rotatably supported thereon (31,32). The pressure transmitting member (7) loaded by the lever members lies freely on a diaphragm (23) of a pressure force measuring cell (8) which together with a weight indicating pressure gauge and a connecting line (25) forms a component assembly which is exchangeably mounted in the base (6).
