Abstract (en)
[origin: EP1500621A1] An elevating mechanism for an elevator system includes two sets of hoisting machines (22, 24) for moving an elevator car (8) and a balance weight (10) up and down; control units (26, 28) for independently controlling the rotation of each of the two sets of hoisting machines (22, 24); and a loop-shaped rope (30) wound around each of the two sets of hoisting machines (22, 24). Of opposed two places held between the two sets of hoisting machines (22, 24), at one place, the rope (30) is wound around a pulley (14) for the car (8) so that the car (8) is hung, and at the other place, the rope (30) is wound around a pulley (16) for the balance weight (10) so that the balance weight (10) is hung. <IMAGE>
