The invention relates to an overhead working truck which is used for high-altitude maintenance and rescue operation. The overhead working truck is formed by a bearing vehicle which is used for bearingand installing an operation mechanism and achieving the walking maneuvering function of the overhead working truck, the operation mechanism which is used for achieving the lifting and folding functions of an operation platform, and a hydraulic control system which is used for achieving lifting and folding control over the operation mechanism. The operation mechanism is fixed to a frame through the bottom of a supporting base and a base plate, and an operation hanging basket is hinged and fixed to the rear end of the operation mechanism. According to the overhead working truck provided by theinvention, the operation mechanism is fixed to the bearing vehicle; under the operation working condition, the operation mechanism is unfolded, and the operation hanging basket is lifted for high-altitude operation; and under the non-operation working condition, the operation mechanism is folded and falls back to the frame so as to be stably supported, so that maneuvering walking and warehousing are facilitated. The overhead working truck provided by the invention is flexible, easy to operate, safe, reliable and capable of being widely applied to high-altitude maintenance and rescue operationoccasions.
