The invention discloses an overhead contact line system operating vehicle. The overhead contact line system operating vehicle comprises a power flatcar and an overhead operating platform. The overheadoperating platform comprises a crank arm and a hanging basket. The crank arm comprises a pedestal, a rotating table, a base arm, a two-section arm, telescoping cylinder assemblies, a telescopic arm and a levelling mechanism. The pedestal is fixedly installed on the power flatcar and the rotating table is installed on the pedestal. One end of the base arm is installed on the rotating table. The end, far away from the rotating table, of the base arm is hinged with one end of the two-section arm, and the other end of the two-section arm is hinged with one end of the telescopic arm. The levellingmechanism is installed at the end, far away from the telescopic arm, of the telescopic arm. The hanging basket is installed on the levelling mechanism so that the hanging basket can be kept horizontal all the time. Each set of the telescoping cylinder assembly comprises a telescoping cylinder, a first connecting rod and a second connecting rod. According to the overhead contact line system operating vehicle, the combined scheme of the base arm, the two-section arm, the telescopic arm and the two telescoping cylinder assemblies is adopted, the hanging basket can move towards the lower side ofthe vehicle and is arranged on the lower side, and the structure is stable and reliable.
