The authors study a novel type of elevator emergency stop device which enables to soften impact force at an emergency halt. A new structure of emergency stop device which is composed of a conventional emergency stop, springs and a specific damper has been already proposed by our laboratory and also its characteristics has been shown by digital simulations [1]. In order to confirm the actual effects of our proposed emergency stop device, various experiments hereafter must be carried out. This time, as a simulator having the same characteristics as the conventional emergency stop device has been made up in order to accomplished the experiments from now on, it is introduced in this paper.
