At least when greater delays are to be expected, these braking, catching or braking devices 9 are operated synchronously, so that between each of the total of at least four guide rails and the elevator car the same resulting braking forces occur - at least substantially.
  • the guide rails 8 are not positioned in the region of the center of the side facing the car. Instead, the guide rails are aligned so that the at least two guide rails, which are arranged on one side of the car, each run directly in the area of the vertical corners of the car, such as the FIG. 2b with the reference numerals 8 shows.

  • the suspension element strand 4 of which in FIG. 2 only representative a single rope-like structure is shown extending from its upper shaft head hinge point A down to a guide roller 10 on the car side wall. This deflects the suspension element strand 4 in the horizontal direction and leads him to a second, also secured to the car side wall guide roller 10. From there, the suspension element strand 4 runs up again, where he in the shaft head via at least one, usually two upper, shaft fixed pulleys 11 in the area above the other Car side wall is guided.
  • These deflection rollers 11 are preferably held on one of preferably two cross members Q, which are each attached to two guide rails, ideally so that they rest on the upper end side of the guide rails. If a second cross member Q is present, this will preferably be designed without pulleys.

  • the forces originating from the suspension element strand 4 are also distributed; they become on each of the two opposite sides of the cage at two different locations in the car 1 or its self-supporting ground platform 5 initiated.
  • This helps to reduce the bending moment acting on the ground platform when catching or sharply braking.
  • this can thereby be made less massive, which usually allows a reduction in the dimensions of the pit or their total savings and at the same time allows a reduction in the mass of the car to be moved and thus also the counterweight - which again reduces the manhole dimensions allowed.
  • the 4: 1 suspension of the car also has the advantage that a relatively small, comparatively fast-running traction sheave drive can be used. This reduces the space required for the drive in the shaft, since the installation space required by the traction sheave drive, including the corresponding safety clearances, is smaller.
  • each provided at each of the two guided car sides at least two guide rails between them limit a space that is used for the cable guide of the car.
  • the at least two pulleys provided on each cabin side are mounted between the two guide rails, there is no need for the suspension beam to intersect the guide rails, in the sense that they somehow extend beyond the guide rails from one side to the other Side, which would cost space. Rather, it is such that at least part of the support means of the suspension element strand lies in the same plane as the guide rails.
  • the suspension element strand can thus be completely accommodated in the narrow space between the car side wall and the shaft wall, just that free space, which is enforced anyway by the guide rails.

  • the ropes may be steel ropes or textile ropes, or combinations of these. Such are particularly preferred because they allow a much larger radius of curvature than pure steel cables, thus allowing smaller pulleys and pulley diameter than steel cables and therefore make the space saving efforts feed.
  • steel cables preference is given to steel ones with a small one Outer diameter between (in each case inclusive) 4 mm and 6.5 mm are used. Such cables also have only a low bending resistance and can therefore also be guided over pulleys with a relatively small outer diameter.
  • the steel cables used are preferably sheathed, usually with a plastic.
  • a non-steel material is preferably used with which a friction coefficient ⁇ ⁇ 2 can be achieved on the surface of the traction sheave. This also supports the pursuit of a car that is as compact and lightweight as possible.

  • the engine forces occurring, for example, in the upward acceleration load the car or the ground platform according to the invention more uniformly, which also allows a more compact and thus space-saving design.
  • Fig. 8 shows an alternative embodiment. This differs from the previously described embodiment by its different type of guide rail assembly. Otherwise, what has been said for the previously described embodiment applies correspondingly, so that the corresponding technical versions for this exemplary embodiment do not have to be repeated again.
  • the classic rail arrangement is realized - on two diametrically opposite car sides each having a guide rail is provided, usually in the region of the center of the respective car side.
  • This construction is material-saving, especially in elevators in high-rise buildings, because it requires only two instead of four guide rail strands for the car.

This contact seal prevents, when the seat rings 56, as explained in more detail below, are pressed against each other, grease reaches into the region of the surfaces (for example, the half-round grooves 52), with which the loose seat rings deflect their associated support means.
  • This clamping body 58 preferably has through holes through which clamping screws 59 are inserted, which can be screwed into the Umlenkrollenbasis Eigen 50. By tightening these screws causes the clamping body 58 exerts a pressure in the direction of the longitudinal axis L of the guide roller and thereby compresses the loose bearing seat rings 56 and clamped together against the integral seat ring 51.

This is especially true when a suspension element strand is used, the individual suspension means are not pure steel cables, but support means, the higher friction against the surface of the Deflection pulley deploy as the mating steel to steel. This is always the case when either jacketed or coated steel cables are used or textile ropes or belts or belts covered with polyurethane or similar materials are used.

  • the second and each further support means can be pulled unhindered over the pulleys, because that seat ring 56 which receives this further support means, is free to move, so that despite rotation of the block Pulley as a whole can take place a rotation of the respective loose seat ring 56, so that the support means can be pulled comfortably in succession over all pulleys 10,11 and 13 and again almost free suspension means can be tightened over the pulleys, the farther the installation of the currently handled Carrying means progresses.
  • This effect can be further improved if one introduces deep groove ball bearings between the base body 50 and the seat rings. For some applications, the use of needle bearings is even cheaper.
  • the individual support means that form the suspension element strand must be stretched evenly so that they wear uniformly.
