The invention discloses a hydraulic forklift. The forklift comprises a handle, a forklift frame and a hydraulic cylinder, and the forklift frame is composed of large wheels, fork wheels, forks and a lifting plate; the hydraulic cylinder is formed by an inner cylinder body and an outer cylinder body in a sleeving manner, and a piston rod in the inner cylinder body is connected with the lifting plate through a spherical ejecting head; the bottom of the inner cylinder body is connected with a supporting seat, and the lower end of the supporting seat is connected with the large wheels; and the two sides of the supporting seat are each connected with a connecting rod component, and the connecting rod component extends to be connected with the fork wheels. A stepping up mechanism is arranged on the supporting seat, and a ratchet head is arranged on the stepping up mechanism to be matched with a ratchet groove corresponding to the outer cylinder body of the hydraulic cylinder. Secondary ratchets are arranged on the hydraulic cylinder, and ratchet bars matched with the ratchets are arranged on the inner cylinder body. A throttling component is further arranged in the hydraulic cylinder. The hydraulic forklift can rapidly ascend, carry out reliable locking, and slowly descends.
