Abstract (en)

An emergency stop apparatus includes a braking mechanism, a pull-up member, a driving mechanism, and an actuating mechanism. The pull-up member is connected to a brake element of the braking mechanism. The driving mechanism includes a connecting part connected to the pull-up member, and causes the braking mechanism to operate. The actuating mechanism is connected to the driving mechanism and actuates the driving mechanism. The connecting part allows only force to an upper side in an ascending-and-descending direction to be transmitted to the pull-up member.
