Problems solved by technology
In the innovation of elevators, the space available in the elevator shaft often limits the scope of application of the elevator concept without machine room
Especially when a hydraulic elevator is to be retrofitted or replaced, it is impractical to apply an elevator solution without a machine room due to the lack of space in the elevator shaft, especially if the hydraulic elevator to be retrofitted or replaced has no counterweight under

Embodiment Construction
[0037] figure 1 It is a schematic structural diagram of an elevator in accordance with the present invention. The elevator is preferably an elevator without a machine room and the drive machine 4 is placed in the elevator shaft. The elevator shown in the figure is a traction sheave elevator with the machine above and without counterweight. The hoisting rope 3 of the elevator travels as follows: One end of the hoisting rope 3 is fastened to a fixed point 16 on a lever 15 immovably and firmly fitted on the elevator car 1, said point 16 being away from the connection of the lever to the elevator car. 1 pivot 17 a certain distance. Therefore, in figure 1 In the situation shown in , the lever 15 serving as compensating means pivots on the elevator car 1 at the fastening point 17 . From the fixed point 16, the hoisting ropes 3 go up and come to a diverting pulley 14 mounted above the elevator car 1 in the elevator shaft - preferably in the upper part of the elevator car 1, from ...

The invention provides an elevator and a method. The elevator is preferably an elevator without a machine room, and wherein the elevator car is supported by a set of hoisting ropes comprising one rope or a number 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 hoisting ropes going upwards and downwards from the elevator car, and the rope portions going from the traction sheave in the direction of the rope portion above the elevator car are under a first rope tension (T1) and the rope portions going from the traction sheave in the direction of the rope portion below the elevator car are under a second rope tension (T2). In addition, the elevator has a compensating device acting on the hoisting ropes to equalizeand / or compensate the rope tension and / or rope elongation and / or to render the ratio of the first and the second rope tensions (T1 / T2) substantially constant. The motion of the elevator is prevented and / or stopped by increasing the ratio of the first rope tension (T1) to the second rope tension (T2).
Description
technical field [0001] The invention relates to an elevator and a method for preventing / stopping the movement of an elevator and for preventing and / or stopping the movement of an elevator. Background technique [0002] One of the goals in the development of elevators is to achieve efficient and economical use of building space. In recent years, this development work has, among other things, resulted in various elevator solutions without machine room and without counterweight. Some good examples of elevators without machine room and without counterweight are disclosed in instructions FI 20021959 and FI 20030153. The elevators described in these specifications are quite efficient in terms of space utilization, since they make it possible to dispense with the space required for the elevator machine room in the building and the space required for the counterweight in the elevator shaft without enlarging the elevator shaft. [0003] In these basically good elevator solutions, t...
