  • Patent number: 9580277
    Abstract: An elevator in which hoisting ropes pass under first and second diverting pulleys, in which a suspension device crosses a line between guide rails. The first and second diverting pulleys may be mounted on the suspension device such that the first and second diverting pulleys may be on a first side and a second side, respectively, in which the sides being opposite, of the line between the guide rails. A frame of the elevator car may be mounted on the suspension device which is supported by a first suspension point and a second suspension point. The first suspension point and the second suspension point may be at a horizontal distance from each other and on opposite sides of each other, and that the first and second suspension points may be on a line between the guide rails or on a line parallel with the guide rails.

  • Patent number: 8783437
    Abstract: A control arrangement is provided for controlling a people mover. The people mover includes a movable conveyor track for transporting people and a control unit. The conveyor track is arranged to move at a first speed when transporting passengers. The control unit is arranged to detect passengers of the people mover with a passenger detection device and to measure the time passed since the last detection of a passenger. After the measured time has reached a set value of a delay time, the control unit operates to decrease the speed of the conveyor track of the people mover either to a lower second speed or to completely stop the movement. The set value of the delay time can be changed by an action of the control unit.

  • Publication number: 20130248295
    Abstract: Elevator in which hoisting roping pass under first and second diverting pulleys; and which suspension means crosses the line between the guide rails; and which first and second diverting pulley are mounted on the suspension means such that they are disposed on a first side and a second side, said sides being opposite, of the line between the guide rails. The frame of the elevator car is mounted on a suspension means for being supported by the first suspension point and the second suspension point comprised in the suspension means, which first suspension point and second suspension point are at a horizontal distance from each other and on opposite sides to each other of a line between the first and second diverting pulley; and that said first and second suspension point are on a line between the guide rails or on a line parallel with it.

  • Patent number: 8235179
    Abstract: An elevator includes hoisting ropes and a compensating device. The hoisting ropes include first rope portions under a first rope tension that go upward from an elevator car and second rope portions under a different, second rope tension that go downward from the elevator car. The compensating device acts in substantially opposite directions on the first and second rope portions in order to do one or more of the following: equalize the first, second, or first and second rope tensions; compensate the rope tensions between the first and second rope tensions; equalize rope elongation in the first, second, or first and second rope portions; compensate the rope elongations between the first and second rope portions; and render a ratio of the first rope tension to the second rope tension substantially constant. The compensating device produces an auxiliary force acting substantially in a same direction as the first rope tension.

  • Patent number: 8141684
    Abstract: An elevator, preferably an elevator without counterweight, comprising a number of diverting pulleys in the upper part of an elevator shaft or equivalent, a number of diverting pulleys in the lower part of the elevator shaft and a number of diverting pulleys on an elevator car, is installed in such manner that at least some of the diverting pulleys for the upper part are rigged in the lower part of the elevator shaft and at least some of the diverting pulleys from which the passage of the ropes is directed upwards are rigged at the same time. The diverting pulleys for the upper part thus rigged are raised in the rigged state to the upper part of the elevator shaft or equivalent and mounted in place.

  • Patent number: 8118138
    Abstract: A method for installing an elevator may include stopping an elevator car or partially completed elevator car in the upper part of an elevator shaft; rigging first portions of hoisting ropes between the car and diverting pulleys in the upper part of the shaft so that the first portions pass via the diverting pulleys in the upper part of the shaft and first diverting pulleys on the car; moving the car to the lower part of the shaft, while supplying ropes from rope reels to the first portions between the car and the diverting pulleys in the upper part of the shaft; and rigging second portions of the hoisting ropes between the car and diverting pulleys in the lower part of the shaft so that the second portions pass via the diverting pulleys in the lower part of the shaft and second diverting pulleys on the car.

  • Patent number: 7537090
    Abstract: A method for tripping safety gear of an elevator, at a speed lower than a gripping speed of the elevator may include: slowing a rope sheave of an overspeed governor of the elevator using a device adapted to slow the rope sheave; disconnecting an actuator connected to the overspeed governor from movement of the rope sheave when the device slows the rope sheave; and tripping the safety gear in an overspeed situation using a rope driving the overspeed governor via the rope sheave. An appliance for tripping safety gear of an elevator may include: an overspeed governor; a rope sheave of the overspeed governor; a device adapted to slow the rope sheave; and an actuator connected to the overspeed governor that is arranged to disconnect from movement of the rope sheave when the device adapted to slow the rope sheave acts to slow the movement of the rope sheave.
