The invention discloses a suspension type elevator anti-falling device. The suspension type elevator anti-falling device comprises control devices and anti-falling mechanisms, all of which are arranged at the top of an elevator car. The two control devices and the two anti-falling mechanisms are arranged in a one-to-one correspondence mode. The control devices comprise weight loss switches and executing mechanisms. The weight loss switches control the anti-falling mechanisms through the executing mechanisms, so that hooks of the anti-falling mechanisms are hooked on stoppers to achieve the anti-falling function of the elevator car. A mechanical detection control device mode is adopted, the weight loss switches on the elevator car are turned on and off according to the weight loss state generated by over-speed descent of the elevator car, braking of the anti-falling device is achieved, the anti-falling device is high in detection speed and reliable in fault detection, the working performance of the anti-falling device can be remarkably improved, the anti-falling device can be automatically started and stopped, the anti-falling automation degree is high, and the anti-falling performance of the elevator is reliable.
