The invention relates to a tower crane lift truck. A right side rack groove (1) and a left side rack groove (2) are mounted on a tower crane steel frame; the mounting heights of the rack grooves are equal to a lifting height; a gasoline engine (3) is mounted at the upper part of a lifting cabin (8); a left side gear (4) and a right side gear (5) are respectively clamped in the left side rack groove (2) and the right side rack groove (1); if the gears and racks are tightly bonded, the gasoline engine (3) is connected with the left side gear (4) and the right side gear (5) through a triangular belt (6); in ascending, the gasoline engine drives the left side gear (4) to rotate through the triangular belt (6), so that the tower crane lift truck is ascended, and the right side gear (5) has an auxiliary function; in descending, the gasoline engine drives the right side gear (5) to rotate through the triangular belt (6), so that the tower crane lift truck is descended, and the left side gear (4) has an auxiliary function; the function conversion of the two gears is controlled by a control box (9); a support steel frame (7) is connected to the lifting cabin (8); and the control box (9) is mounted in the lifting cabin (8).
