Suspension type trolley mechanical hoisting device

The invention discloses a suspension type trolley mechanical hoisting device. The device comprises at least one horizontally arranged hanging rail, wherein supporting legs are arranged at one end of the hanging rails, a hanging and fixing assembly is arranged at the top of the other end of the hanging rails, an annular hanging ring used for hoisting a hydraulic spring mechanism is arranged at thebottom of one end, provided with the hanging and fixing assembly, of the hanging rails, and a position adjusting component is arranged between the annular hanging ring and the hanging rails. The hoisting device is simple in overall structure and can be suitable for a narrow operation space of a ZF8-550 type HGIS switch, and due to the simple structure, the whole weight is small, heavy preparationwork such as laying steel plates does not need before operation, and the device can be directly placed on a grassland or an overhaul hole cover, and meanwhile, the overall size is moderate, and the occurrence of collision dama
