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). The wheel loading balance is easily assembled, is rugged and accurate and its accuracy of measurement is not adversely affected by shocks or vibrations.
