The escape device (2) has a shaft (213) which rotates in a stand (22), a rod (24) fastened securely to the stand and located above the shaft, and a winch (25) which is mounted securely on the shaft and turns with it. The descending speed of the escape carrier and a user in the escape carrier is reduced by the frictional engagement between the brake shoe and the brake drum.
