The invention belongs to the technical field of elevator safety design and discloses a sudden falling alarm system for a vertical-lifting elevator. The sudden falling alarm system comprises a falling protection controller, a power source, a gravity acceleration sensor, a wireless signal alarm, a stress sensor and wire harnesses. The falling protection controller, the power source, the gravity acceleration sensor and the wireless signal alarm are all arranged on the upper surface of the top of an elevator cab in sequence. The stress sensor is arranged on the lower surface of the top of the elevator cab. According to the sudden falling alarm system, when the falling protection controller monitors elevator cab falling through the gravity acceleration sensor, the wireless signal alarm is controlled to be turned on, and rescue workers are informed to arrive at the elevator cab in time. The sudden falling alarm system is reasonable in design, simple in structure and applicable to optimal design of a vertical elevator falling damage reduction system.
