The invention discloses a reactive-force hydraulic control mechanism, and belongs to the technical field of elevator safety design. The reactive-force hydraulic control mechanism comprises a falling protecting controller, a power source, a gravity acceleration sensor, a wireless signal alarm device, a force sensor, a wire harness, a pedal and high pressure springs. The falling protecting controller, the power source, the gravity acceleration sensor and the wireless signal alarm device are sequentially arranged on the upper surface of the top of an elevator car. The force sensor is arranged on the lower surface of the top of the elevator car. The pedal is arranged at the bottom of the elevator car. The high pressure springs are arranged between the pedal and the lower bottom face of the elevator car. According to the reactive force hydraulic control mechanism, when the falling protecting controller monitors falling of the elevator car through the gravity acceleration sensor, the wireless signal alarm device is controlled to be started to inform ambulance men to arrive in time. The reactive-force hydraulic control mechanism is reasonable is design, simple in structure and suitable for the optimal design of a vertical elevator falling loss reducing system.
