Abstract (en)
An elevator system wherein a hoisting machine (11) is mounted on an elevator car (4) or a counterweight (10), comprises a first brake-releasing mechanism (30) and a second brake-releasing mechanism (40) for mechanically releasing brake of a braking device (20) of the hoisting machine (11), in case of malfunction of the elevator. The releasing of brake of the braking device (20) is performed by actuating each of the brake-releasing levers (31,41) by operating operation ropes (33,43) provided in each of the brake-releasing mechanisms from the ground. Furthermore, because the elevator system comprises two sets of brake-releasing mechanisms, it is possible to perform more stable releasing of the braking device (20) with facility and without fail by selecting the brake-releasing mechanism suitable for the situation of the boarding of passengers, regardless of the number of passengers inside the elevator car (4). <IMAGE>
