The invention belongs to the technical field of elevator safety design and provides a three-mechanism synchronous clamping system. The synchronous clamping system comprises a falling protection controller, a power source, an acceleration sensor, a wire harness and positive electromagnetic field emitting mechanisms. The falling protection controller, the power source, the acceleration sensor and a wireless signal alarm are sequentially arranged on the upper surface of the top of a lift car. The first positive electromagnetic field emitting mechanism and the second positive electromagnetic field emitting mechanism are both arranged on the lower bottom face of the lift car. The third positive electromagnetic field emitting mechanism and the fourth positive electromagnetic field emitting mechanism are arranged in the lift car. According to the synchronous clamping system, when the falling protection controller monitors that the lift car is falling through the acceleration sensor, the electromagnetic field emitting mechanisms are controlled to start, and an air cushion is formed between the first electromagnetic field emitting mechanism and the second electromagnetic field emitting mechanism to provide falling buffering force for trapped people. The synchronous clamping system is reasonable in design, simple in structure and suitable for optimization design of a vertical elevator falling loss reduction system.
