摘要:
An elevator may include an elevator car, one or more hoisting ropes, a traction sheave, an overspeed governor, at least one safety gear, a locking mechanism, and guide rails. The car may be suspended by the one or more hoisting ropes. The traction sheave may move the car using the one or more hoisting ropes. The at least one safety gear and locking mechanism may be fitted in conjunction with the car. The overspeed governor may be configured to activate and release, via a linkage, the at least one safety gear during operation of the elevator. The locking mechanism may be configured to activate and release, by operatively acting on the linkage, the at least one safety gear during installation, maintenance, or installation and maintenance of the elevator. When activated, the at least one safety gear may engage one of the guide rails to lock the car in place.

Elevator, preferably an elevator without machine room, comprising at least an elevator car (101) moving along guide rails (1), a counterweight (102) moving along guide rails (2) and an elevator motor (106) driving them, wherein the guide rails are fixed in place by means of guide fixing brackets (112). The width of the guide fixing bracket (112) in the vicinity of the car guide rails (1) is substantially equal to the width of the car guide rail plus the thickness of the rail clips in the guide fixing bracket.

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.

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.

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.
摘要:
The object of the invention is a method for modernizing an elevator, and a traction sheave elevator, which elevator comprises at least an elevator car and a traction sheave that moves the elevator car by means of elevator ropes, the rim of which traction sheave comprises one or more rope grooves. In connection with modernization a traction sheave is installed as the traction sheave of the elevator, the rope grooves of which traction sheave comprise a material, the frictive traction achieved by which is greater than the frictive traction between the parent material of the metallic traction sheave and the elevator ropes.

The object of the invention is a traction sheave elevator and a rope (3) that contains metal as a load-bearing material, such as the suspension rope of an elevator, which rope comprises at least one or more strands (7) laid from metal wires (9) and which rope (3) is lubricated with a lubricant (8). Another object is the use of the aforementioned lubricant for lubricating the rope (3). The lubricant (8) comprises at least oil and thickener, which thickener in the lubricant (8) comprises at least 10% or more of the mass of the lubricant (8).

A transport system includes a motor for moving the transport appliance and a power supply circuit of the motor. The power supply circuit is connected between the motor and a power source that is limited (Plim) in its dimensioning. An energy storage that is limited (Elim) in its capacity is fitted in connection with the power supply circuit of the motor. The control arrangement includes a determination of the charging status (EQ) of the energy storage; a determination of the movement reference of the transport appliance; and a control of the movement of the transport appliance as a response to the determined movement reference of the transport appliance. The movement reference of the transport appliance is determined on the basis of the amount of energy that can be discharged from the energy storage and/or on the basis of the amount of energy that can be charged into the energy storage as well as on the basis of the travel distance of the transport appliance.
摘要:
A set of elevators includes a plurality of elevators without counterweight, a power supply, and a common control system. The plurality of elevators has a common connection to the power supply. The common control system includes one or more instructions to prevent or delay dispatch of an elevator car stopped at a floor if, at that instant, within a set period of time, or at that instant and within the set period of time, power consumed from an associated electrical network by the set of elevators or fed into the associated electrical network by the set of elevators together exceeds a set value. A method for controlling a set of elevators includes determining whether power consumed together exceeds a set value, and when the power consumed exceeds the set value, then departure of a next elevator car to be dispatched is prevented or delayed.
