A transport cart (3) and a transmission device thereof (32). The transmission device comprises: a crawling assembly (320), a rotary drive assembly and a crawling drive assembly. The crawling assembly comprises: a wheel frame (321), comprising a first end and a second end opposite to the first end, the wheel frame extending from the first end to the second end; a driving wheel (322), mounted at the second end and having an axis perpendicular to the extending direction of the wheel frame; and a guide wheel (323), mounted at the second end and having an axis parallel to the extending direction of the wheel frame. The present transport cart provided with the described transmission device may move along both a horizontal rail and a vertical rail and may quickly switch between the horizontal rail and the vertical rail, thus improving the moving efficiency.
