摘要： The invention aims to provide an emergency braking device. The emergency braking device can work based on the moving acceleration of an elevator cabin when a sling is cut off without a special device. The emergency braking device is arranged on an elevator cabin (12) and works when a lifting rod (19a) is lifted. The emergency braking device is provided with a braking portion (52a, 52b) for braking the elevator cabin, a braking portion motion mechanism, and a restraining force supply mechanism (51). The lifting rod (19a) is configured to rotate around a fulcrum (58b), one end of the lifting rod (19a) is equipped with the rotating force that allows the lifting rod to rotate around the fulcrum (58b), and the lifting rod (19a) is usually held on a position (61). The braking portion (52a, 52b) works within a range that the lifting rod (19a) is lifted to be a horizontal position (62).
