Abstract

A wheel load indicator comprises a rectangular flat plate (1) of a light material having measuring properties. A series of recesses (4) forming webs (5) are provided along two lateral edges (6) of the plate (1). Strain gauges (12) are adhesively bonded to walls of bores (10) in the area of the webs (5) to determine the shearing stress under the load of a wheel (100) which has driven on the bending portion (3).
