PROBLEM TO BE SOLVED: To provide two excitation waves of different frequency characteristics for a test body by reconstructing an existing shaking table. SOLUTION: A main shaking table 1 capable of being excited by a hydraulic jack 2 is disposed. A sub shaking table fixture 3 is attached to the upside of the main shaking table 1. The sub shaking table 4 is attached to the fixture 3 via the hydraulic jack 5, and the shaking table test device is formed. When it is installed on the ground and a vibration test by an earthquake of a climbing crane of the form of being supported by a support structure at a required height level is performed, the lower end of a test body 6 of the climbing crane is attached to the upside of the main shake table 1. While the sub shaking table 4 is connected to the required height level of the test body 6, the main shaking table 1 is vibrated by a simulated seismic wave, the sub shaking table 4 is vibrated by a simulated response wave of the support structure by the seismic wave, and they are input as two different excitation waves to the test body 6.
