A safety braking device comprises a base, a sliding piece, a first pushing piece, a winder and a first emergency stop structure. The sliding piece, the first pushing piece, the winder and the first emergency stop structure are arranged on the base. The winder is used for winding or releasing a rope body; the first pushing piece provides a first pushing force to act on the sliding piece; when the end, connected with a load, of the rope body is subjected to instant downward force greater than the first pushing force of the first pushing piece, the emergency stop structure acts to enable the winder to stop releasing the rope body, which can generate a stop action in time when a person or an object falls down.
一种安全掣动装置包括有基座、滑动件、第一顶推件、卷线器及第一急停结构,滑动件、第一顶推件、卷线器及第一急停结构设置于基座上,卷线器用以卷收或是释出一绳体,该第一顶推件提供一第一顶推力作用于该滑动件,当绳体连结负载的一端受到瞬间向下的力大于该第一顶推件的第一顶推力时,该急停结构作动使该卷线器停止释出该绳体,其可在人或物的坠落当下及时产生中止的动作。
