13 located in the upper part of the shaft above the path of
         a counterweight 2 moving along counterweight guide rails
         11. From the anchorage, the ropes run downward and are
         passed around diverting pulleys 9 suspending the counter-
         weight, which diverting pulleys 9 are rotatably mounted on
         the counterweight 2 and from which the ropes 3 run further
         upward to the traction sheave 7 of the drive machine 6, pass-
         ing  around  the  traction  sheave  along  rope  grooves  on  the
         sheave. From the traction sheave 7, the ropes 3 run further
         downward to the elevator car 1 moving along car guide rails
         10, passing under the car via diverting pulleys 4 used to sus-
         pend the elevator car on the ropes, and going then upward
         again from the elevator car to an anchorage 14 in the upper
         part of the elevator shaft, to which anchorage the second end
         of the ropes 3 is fixed.
           Anchorage 13 in the upper part of the shaft, the traction
         sheave 7 and the diverting pulley 9 suspending the coun-
         terweight on the ropes are preferably so disposed in rela-
         tion to each other that both the rope portion going from the
         anchorage 13 to the counterweight 2 and the rope portion
         going from the counterweight 2 to the traction sheave 7 are
         substantially  parallel  to  the  path of  the  counterweight  2.
         Similarly, a solution is preferred in which anchorage 14 in
         the upper part of the shaft, the traction sheave 7 and the
         diverting pulleys 4 suspending the elevator car on the ropes
         are so disposed in relation to each other that the rope por-
         tion going from the anchorage 14 to the elevator car 1 and
         the rope portion going from the elevator car 1 to the trac-
         tion sheave 7 are substantially parallel to the path of the
         elevator car 1. With this arrangement, no additional divert-
         ing pulleys are needed to define the passage of the ropes in
         the shaft. The rope suspension acts in a substantially centric
         manner on the elevator car 1, provided that the rope pul-
         leys 4 supporting the elevator car are mounted substantially
         symmetrically relative to the vertical center line passing via
         the center of gravity of the elevator car 1.
           The drive machine 6 placed in the elevator shaft is pref-
         erably  of  a  flat  construction,  in  other  words,  the  machine   has a small depth as compared with its width and/or height,
                                                              or at least the machine is slim enough to be accommodated
                                                              between the elevator car and a wall of the elevator shaft.
                                                              The machine may also be placed differently, e.g. by dispos-
                                                              ing the slim machine partly or completely between an as-
                                                              sumed extension of the elevator car and a shaft wall. The
                                                              elevator shaft can be provided with equipment required for
                                                              the supply of power to the motor driving the traction sheave
                                                              7 as well as equipment for elevator control, both of which
                                                              can be placed in a common instrument panel 8 or mounted
                                                              separately  from each other or integrated  partly  or wholly
                                                              with the drive machine 6.
                                                               The drive machine may be of a geared or gearless type. A
                                                              preferable solution is a gearless machine comprising a per-
                                                              manent magnet motor. The drive machine may be fixed to
                                                              a wall of the elevator shaft, to the ceiling, to a guide rail
                                                              or guide rails or to some other structure, such as a beam
                                                              or frame. In the case of an elevator with machine below, a
                                                              further possibility is to mount the machine on the bottom of
                                                              the elevator shaft. Figure 24 illustrates the economical 2:1
                                                              suspension, but the invention can also be implemented in an
                                                              elevator using a 1:1 suspension ratio, in other words, in an
                                                              elevator in which the hoisting ropes are connected directly
                                                              to the counterweight and elevator car without diverting pul-
                                                              leys. Other suspension  arrangements are also possible in
                                                              an implementation of the invention. The elevator presented
                                                              in the figure has automatic telescoping doors 18, but other
                                                              types of automatic doors or turning doors can also be used in
