ABSTRACT:
A device for measuring the stress of tangential friction of a shoe on a surfacing for the ground comprises a guiding device, a carriage displaceable over the length of said guiding device, a shoe on said carriage and being subjected to a vertical load dynamometric pick-up means suitable for measuring the tangential friction of the shoe on the surfacing in the course of the displacement of said carriage, a driving assembly for moving the carriage in translation and recorder means connected to the dynamometric pick-up means to record the variation of tangential friction of the shoe on the surfacing.
