The disclosure discloses a steel formwork trolley for tunnel lining, including a steel structure system, a hydraulic system and an electrical system. The steel structure system comprises a frame body assembly, a formwork assembly, an aligning and translation assembly, a support assembly and a walking assembly. An aligning mechanism adjusts the left and right translation of the top formwork through the expansion and contraction of the aligning oil cylinder; a translation mechanism adjusts the movement of the platform beam through the expansion and contraction of the translation oil cylinder; and the hydraulic system uses a three-position four-way manual reversing valve for reversing. Each oil cylinder is provided with a hydraulic lock and controlled by using one reversing valve to expand and contract the oil cylinder, and the hydraulic lock locks the four lifting oil cylinders to ensure that the formwork does not slide down at the positioning elevation.
