Abstract: A treadmill for horses includes a basic structure with a frame. The frame includes two parallel longitudinal beams which are spaced from each other by more than the width of the animal and comprise supports for an at least three-ply, continuous support covering. The support covering includes from top to bottom a sheet steel plate, a damping plate and a sliding plate. The upper strand of an endless belt runs on the latter. Its service life is extended to a considerable extent if at least one lubricant line each opens above the lower strand of the belt on either side of the longitudinal central line of the belt, so that the upper side of the lower strand is supplied with lubricant, thus forming a lubricating film between the lower side of the upper strand and the sliding plate.
