FIELD: transportation.
SUBSTANCE: vehicle is connected to draft devices with a possibility of measurement of draft force and the tangent forces applied to rims of driving wheels, at least three dynamometers are used one of which is arranged on the horizontal line of the tractor gravity center trace. The device has a stopper with the draft dynamometer, and the base has depressions with the tangent force dynamometers linked with the movable carriages on bearing rollers. The movable carriages consist of idling rollers and retractable hooks, and the niches bottom has inclined guiding planes.
EFFECT: possibility of determination of draft force on the driving wheel rim.
