The invention provides a hanging basket type moving platform for a rocket engine test. The hanging basket type moving platform is used for operating platforms of different heights, such as engine transportation and installation, and the butt-joint function of an engines and a test bed is achieved. The hanging basket type moving platform comprises a trolley with a three-layer steel structure, rotary single-arm booms, wheels and movable turning plates. Each rotary single-arm boom is composed of a single-arm beam, a manually-rotatable rocker arm, a sliding wheel and a rotary pull rod. The hanging basket type moving platform has the beneficial effects that the platform structure is in the form of the steel structure trolley, a total of three layers; the operating demands of the engine at different heights are met; the hanging basket type moving platform is hung on a track and can move in the direction of a guide rail, and the problem about engine transportation under the space limitation condition of a test pit is solved; and the rotary single-arm boom structure is developed for the moving platform, the vertical butt-joint problem of the engine and the test bed in the narrow space can be solved in cooperation with an overturning lifting tool, and the hanging basket type moving platform is easy to operate and high in practicability.
