The hammer is intended for testing shock absorption of aircraft landing gears in conditions similar to those of landing and taxiing, testing “shimmy” vibrations of landing gears, as well as testing brakes, wheels and tires. The stand allows to apply dynamic loads in the form of driving over an obstacle.
