ELEVATOR PULLEY ARRANGEMENT |
摘要 |
An elevator having an elevator car with a car frame on which are mounted a first set of diverting pulleys from which the hoisting ropes go downwards and a second set of diverting pulleys from which the hoisting ropes go upwards. The rope tension in the rope portions going from the diverting pulleys of the first set is smaller than the rope tension in the rope portions going from the diverting pulleys of the second set by a specified ratio. According to the invention, the diverting pulleys of the first set are at a larger average distance from the car frame than the diverting pulleys of the second set. In a possible inventive arrangement, the distance of an up-direction diverting pulley from the car frame is smaller by a specified ratio than the distance a corresponding down-direction diverting pulley. |
