The invention provides a novel elevator capable of preventing falling. The novel elevator capable of preventing falling is characterized by comprising a storing hydraulic cylinder (1), a hydraulic cylinder (2), a piston (3), a guide rod (4), a solenoid valve (5), a pressure sensor (6), an one-way throttling valve (7), a safety valve (8) and a ball valve (9); the hydraulic cylinder (2) is divided into a left chamber 2-I and a right chamber 2-II through the piston (3), wherein the left chamber 2-1 is communicated with the storing hydraulic cylinder (1), and while the right chamber 2-II is connected with the solenoid valve (5), the pressure sensor (6) and the one-way throttling valve (7); the other end of the solenoid valve (5) is connected with the safety valve (8) and the ball valve (9); the other one of the ends of the safety valve (8), the ball valve (9) and the one-way throttling valve (7) are connected with the storing hydraulic cylinder (1). The novel elevator capable of preventing falling is mainly applied to elevating devices applied to automobile, tractors, harvester and other assembly production lines; the elevator can be independently used or combined with a conveying line to use to prevent matters from falling down during elevating.
