Analogue simulation test rack for performance test of suspension bridge stiff girder hoisting cable-striding crane

The present utility model relates to a test device of suspension bridge construction, especially to an analogue simulation test rack for a performance test of a suspension bridge stiff girder hoisting cable-striding crane. The test rack at least comprises two test racks which are respectively connected with a first simulation main cable and a second simulation main cable, and is characterized in that the first simulation main cable is connected with a fixing test rack, and the second simulation main cable is connected with a mobile test rack. The test rack can be used for simulating main cable torsion and main cable interval changing caused by working of a cable-striding crane on a main cable, and reflecting working conditions and environments of the cable-striding crane practically, thus a testing result of the performance of the cable-striding crane is reliable and credible, the performance requirement of a hoisting stiff girder is satisfied by the cable-striding crane, and safety of hoisting equipment of h
