Aircraft tractor running-in test-bed is an important tool for aircraft tractor performance research. Indoor testbed was used to simulate real road. Hydraulic loading pump was used as the power absorption device，to provide simulated driving resistance for aircraft tractor running-in test. Load device was specially designed to simulate aircraft landing gear，to test the aircraft tractor blessinglifting device. And the test method was introduced.The designed aircraft tractor runningin testbed can solve and avoid some disadvantages brought by outdoor aircraft tractor running-in test.
