Abstract:
An elevator, preferably 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 the elevator car, is installed by a method in which at least some of the diverting pulleys are pre-rigged. The rigged diverting pulleys are brought into the elevator shaft together with the car, and the hoisting ropes are stretched to their proper length when the diverting pulleys in the upper and lower parts of the shaft are mounted in place.
Abstract:
An elevator, preferably an elevator without counterweight, wherein the elevator car is suspended by hoisting ropes consisting of a single rope or a plurality of parallel ropes. The elevator has a traction sheave which moves the elevator car by means of the hoisting ropes. The elevator has rope portions of the hoisting ropes going upwards and downwards from the elevator car, and the elevator is provided with a safety gear fitted in conjunction with the elevator car and engaging a guide rail. The elevator is provided with a locking mechanism fitted in conjunction with the elevator car for locking the elevator car in place, said mechanism comprising means for activating and releasing the safety gear fitted on the elevator car.
Abstract:
An elevator, which preferably is an elevator without counterweight and in which an elevator car is suspended by means of a set of hoisting ropes comprising one rope or a number of parallel ropes. The elevator has a traction sheave that moves the elevator car by means of the hoisting ropes. The elevator comprises rope portions of hoisting ropes going upwards and downwards from the elevator car, and the elevator has a compensating device acting on the hoisting ropes to equalize and/or compensate rope tension and/or rope elongation. The compensating device acting on the hoisting ropes of the elevator comprises at least one slack rope prevention means for preventing uncontrolled slackening of the hoisting ropes and/or uncontrolled motion of the compensating device.
Abstract:
An elevator, preferably an elevator with-out 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.
Abstract:
An elevator, preferably an elevator without machine room, in which the hoisting machine (10) engages the hoisting ropes (3) by means of a traction sheave (11), the elevator car (1) being at least partially supported by the hoisting ropes serving as a means of moving the elevator car (1). The elevator car is suspended on the hoisting ropes (3) by means of at least one diverting pulley (13,14) from whose rim the hoisting ropes go upwards from both sides and at least one diverting pulley (7,5) from whose rim the hoisting ropes go downwards from both sides of the diverting pulley. The traction sheave (11) engages the rope portion between these diverting pulleys (13,5).
Abstract:
The invention relates to a method for transporting passengers on a travelator, and to a travelator. The comprises: a plurality of successive conveyors arranged to form (a) an acceleration section, which includes successive conveyors having constant speeds stepwise increasing in the transport direction for accelerating a passenger transport speed from a substantially slow initial speed to an increased transport speed, (b) a constant-speed section containing at least one conveyor having a constant passenger transport speed, and (c) a deceleration section containing successive conveyors having constant speeds stepwise decreasing in the transport direction for decelerating the passenger transport speed from the constant transport speed to a decelerated final speed. The speeds of the conveyors in the acceleration section and the deceleration section are adapted so that the average acceleration experienced by the passenger over the entire length of the acceleration and deceleration sections is constant. Adjacent successive conveyors in the acceleration and deceleration sections include a common diverting element having a speed change point at which the speeds of the adjacent successive conveyors are different in the transport direction.
Abstract:
An elevator in which the elevator car is suspended by means of hoisting ropes consisting of a single rope or several parallel ropes, said elevator having a traction sheave which moves the elevator car by means of the hoisting ropes. The elevator has rope portions of the hoisting ropes going upwards and downwards from the elevator car, and the rope portions going upwards from the elevator car are under a first rope tension (T1) which is greater than a second rope tension (T2), which is the rope tension of the rope portions going downwards from the elevator car, and that the elevator comprises a compensating system for keeping the ratio (T1/T2) between the first and the second rope tensions substantially constant.
Abstract:
An elevator built in place of an earlier elevator in an elevator shaft or equivalent. In the elevator, the elevator car is suspendended by means of hoisting ropes consisting of a single rope or several parallel ropes. The elevator has a traction sheave which moves the elevator car by means of the hoisting ropes. The elevator has rope portions of the hoisting ropes going upwards and downwards from the elevator car, and the rope portions going upwards from the elevator car are under a first rope tension (T1) which is greater than a second rope tension (T2), which is the rope tension of the rope portions going downwards from the elevator car, and the elevator has been built in place of an earlier elevator mounted in the elevator shaft or equivalent or by making modifications in the earlier elevator.
Abstract:
The invention relates to an elevator provided with a coated hoisting rope (9), in which elevator a hoisting machine engages a set of hoisting ropes by means of a traction sheave (5), said set of hoisting ropes comprising coated hoisting ropes (9) of substantially circular cross-section which have a load-bearing part twisted from strong steel wires (16). The cross-sectional area of the steel wires (16) of each hoisting rope is larger than about 0.015 mm2 and smaller than about 0.2 mm2, and the strength of the steel wires (16) is greater than about 2000 N/mm2. Moreover, the core of each hoisting rope (9) consisting of steel wires (16) is coated with a substantially thin sheath (17) softer than the core, forming the surface of the hoisting rope.
