Abstract

In a counterweight (10) which rises and lowers in balance with a car rising and lowering in an elevator system (100), the counterweight (10) has an upper counterweight (30) and a lower counterweight (32), and the upper counterweight (30) and the lower counterweight (32) can be separated from each other. Also, when the counterweight (10) is separated, the upper counterweight (30) has an upper brake device (36) for stopping the upper counterweight (30), and the lower counterweight (32) has a lower brake device (38) for stopping the lower counterweight (32). <IMAGE>
