Description

200840791 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a lifting apparatus in a building having at least one conversion floor. The invention is defined in the preamble of the separate item of the patent application. [Prior Art] A modern elevator for a building having 30 floors and more than 30 floors has a plurality of conversion floors served by a lifting device. Such lifting equipment includes a group of at least two lifts. The first elevator serves the conversion floor directly from the entrance hall, i.e., the passengers are coarsely distributed from the entrance hall to the different conversion floors by a high speed elevator. The second lift performs a fine distribution of passengers from the transition floors to their target floors. The elevator typically includes a lift car that can be moved vertically in a hoistway and receives passengers for transporting them to a desired floor in the building. In order to cope with this work, the elevator usually has at least the following elevator components: a drive having a motor and a drive pulley, a plurality of steering rollers, a plurality of tension members, a counterweight, and a pair for guiding the lift Rails for compartments and counterweights. In this case, the motor generates the power needed to transport passengers in the lift car. This item is usually performed with an electric motor. This directly or indirectly drives a drive pulley that is in contact with a force member. This tension member can be a belt or a cable. The tension member is used to suspend and transport the lift car and the counterweight, both of which are suspended such that their gravitational force acts in the opposite direction of the phase of the 200840791. Correspondingly, the combined gravity that must be overcome by the drive means is substantially reduced. Further, due to the large contact force of the tension member that drives the pulley, a large driving torque can be transmitted to the tension member via the drive pulley. This tension member is guided by a number of steering rollers. The importance of the optimum use of the hoistway volume in the construction of the elevator is increasing. Especially in high-rise buildings where construction space must be highly utilized, it will be necessary to efficiently manage the passengers carried in a given hoistway volume. This object can be achieved first by the optimal space saving configuration of the lifting assemblies (which would result in a larger lift car) and by the lift of a plurality of independent lift cars that can be moved vertically in a hoistway. EP 1 5 2 6 1 03 shows a lifting device having at least two elevators in a building that is divided into a plurality of sections. In this case, an interval includes a defined number of floors, which are serviced by a lift. Each elevator is assigned an interval. A transition floor is arranged to travel from one interval to another. At least one of the elevators has two lift cars that are movable independently of each other and vertically up and down on the two carriage rails. The configuration of the two shuttle cars is used to help avoid unnecessary waiting time at the transition floors. It is known from EP 1 48 9 033 to have at least two elevators arranged in the same hoistway from each other. Each lift car has its own drive unit and its own counterweight. The drive units are disposed adjacent the first and second hoistway walls, and the counterweights are also suspended separately from the associated drive unit by a plurality of drive or support cables located adjacent the first or second hoistway wall . The shafts of the drive pulleys of the drive units are configured to be perpendicular to the first and second hoistway walls of 200840791. These two independently movable elevators will ensure a high transport performance. Positioning the drive means in the hoistway adjacent the first or second wall such that a separate engine compartment becomes redundant' and such that the drive elements are in the hoistway top can have a space-saving compact configuration. SUMMARY OF THE INVENTION It is an object of the present invention to further increase the transport performance of a lifting device under a given hoistway surface in a building having a zone separation and at least one conversion floor. The above objects are achieved by the invention as defined in the independent claim of the patent application. The lifting apparatus according to the present invention is located in a building having at least two elevators, wherein the building is divided into a plurality of building sections, and each of the elevators has at least one lifting compartment. Each of the elevator cars can be independently moved in an associated compartment section by its own drive. In addition, each compartment section has at least one transition floor. The first elevator has at least three lift cars vertically disposed one above the other in a hoistway, and includes an intermediate car and two adjacent cars, wherein the intermediate car is independently movable in an intermediate compartment section, and The two adjacent cars can be independently moved in two adjacent car sections. In this case, the intermediate compartment section and an adjacent compartment section serve at least one common floor. In addition, at least one of the compartment sections is assigned to two building sections. Since the at least three ascending and descending compartments of the elevator that can be moved up and down independently of each other, the lifting apparatus has a significantly higher transport performance. The waiting time at the transition floors in 200840791 is then further reduced, and the generation of waiting cycles can be largely avoided. In addition to this, the lifting device has greater flexibility in the dispatching process because in a typical lifting mode it will be possible to switch from one building interval to the next by switching floors. Here, it is possible to reach the areas of adjacent building sections without switching by the conversion floor. Another advantage of a lifting apparatus having a plurality of overlapping compartment sections is that a passenger can transition from an intermediate compartment section to an adjacent compartment section at any desired floor in the overlapping sections of the compartments. This will guide the passengers more flexibly. In addition, a plurality of floors located in the overlapping areas of the compartments can be serviced by two elevator cars, thereby improving the transport performance of the lifting equipment. Advantageously, the at least one elevator car of the second elevator is a duplex car having at least two cars vertically arranged one above the other. Because the two cars are substantially connected and therefore can only be moved together, they are associated with the same car compartment. The advantage of this double-car lift is the doubling of the available car volume of the lift car. As a result, up to twice as many passengers can be carried in one trip. Advantageously, the duplex car serves at least two transition floors that are arranged one above the other. The advantage of this lifting device is that in the case where the conversion floor is doubled, the waiting time on each conversion floor can be further reduced. The transition floors have a transition or waiting space for conversion. In the case where the number of conversion spaces is doubled, the conversion will be carried out substantially without conflict, 200840791 and if the waiting time still occurs despite the improved transportation performance, then the passenger will have twice as much waiting Space volume. Thus, 'in any case, it will make it more comfortable to stay in the transition floors or in the transition or waiting space. Advantageously, at least three compartment sections can be assigned to at least two adjacent building sections. Advantageously, the intermediate compartment section is assigned to an architectural zone, and the two adjacent compartment sections are each assigned to the same building section and an adjacent upper or lower building section. The advantage of this lifting device is the flexible passenger guidance. In the embodiment of the embodiment described herein, it is possible to change from one floor of a building section to one floor of an adjacent building section, and this is achieved without the need for a possible transition of the converted floor that must be considered. Advantageously, the elevator cars are movable through at least three drives associated with the elevator cars. This lifting device has the advantage that the drives can be arranged in the hoistway in a space-saving and flexible manner without colliding with the elevator cars. Advantageously, at least three of the drive units associated with the elevator cars are disposed at the first hoistway wall or the second opposing hoistway wall. The advantage of this lifting device is the placement of the drive means between the elevator car and the first and second hoistway walls. The space at the top of the hoistway or the pit of the hoistway equipped with such drives can therefore be saved. Advantageously, the drive of the intermediate lift car is positioned at the first hoistway wall and the two drive units of the adjacent lift cars are positioned opposite the second hoistway wall of -10- 200840791. The advantage of this lifting device is that it is resilient and simple to position a number of drives and associated lift cars in the same hoistway. In the conventional configuration of the drives in the top of the hoistway, the number of drives that can be installed is limited by the available space within the top of the hoistway. Likewise, the collision-free guidance of the tensioning elements carried out in the conventional configuration of such a drive unit located in the top of the hoistway will be tightly constrained. The invention will be further elucidated and described in detail below by means of a number of embodiments and drawings. [Embodiment] A hoistway is a space defined by six boundary surfaces, wherein one or more elevator cars are moved along a running channel. Typically, four hoistway walls, a ceiling, and a floor form the six boundary faces. The definition of the hoistway can be extended to also provide a plurality of operational passages in a hoistway that are horizontally adjacent to each other, and one or more lift carriages are movable along each of the operational passages. Fig. 1 shows an elevator having at least three elevator cars 7a, 7b, 7c, each of which has its own drive means A1, A2, A3, and is movable independently of each other in the vertical direction. In this case, an intermediate lift car 7a is disposed between two adjacent lift cars 7b, 7c located below and above the intermediate lift car 7a, respectively. The associated drives A1, A2, A3 are laterally disposed at the first and second hoistway walls. The first and second well walls are those that have no well doors and are opposite each other. The drive unit of the intermediate lift car 7a 200840791 A1 is placed at the first hoistway wall, and the two drive units A2, A3 of the adjacent lift cars 7b, 7c are placed opposite the second hoistway wall. In this case, the drive units A 1 , A 2, A 3 are alternately placed on the opposite hoistway walls. Additional drive means (not shown) of the other lift cars are alternately disposed at the first and second hoistway walls in a manner corresponding to the alternating sequence of drive means. In Fig. 1, the drive units A1, A2, A3 are placed at three different hoistway heights, wherein the drive units A2, A3 of the adjacent lift cars 7b, 7c are placed in the drive unit A1 of the intermediate lift car 7a. Above or below. Typically, the vertical distance between the intermediate drive unit A 1 and the adjacent drive units A2, A3 is at least one cabin height. However, it is also possible to position the two drive units at the same hoistway height. For example, the drive unit A 1 of the intermediate lift car 7a can be disposed on the first hoistway wall, and the drive unit A3 of the adjacent upper hoistway 7c can be disposed at the opposite second hoistway wall at the same hoistway height. The advantage of this configuration is that the two drives A 1 , A3 can be easily maintained. In particular, the maintenance of the drives can be performed by a common platform. The drive units A1, A2, A3 have respective motors M1, M2, M3 and respective drive pulleys 1 a, 1 b, 1 c. The motor Μ 1, Μ 2 ' Μ 3 is configured to be in operative contact with the drive pulleys 1 a , 1 b , 1 c and to drive the tension member Z 1 by driving the pulleys 1 a , 1 b , 1 c, Z 2, Z 3. The drive pulleys 1 a, 1 b, 1 c are designed to receive one or more tension members Z 1 , Z 2, Z 3 . The tension members Z1, Z2, Z3 are preferably belts, such as wedge-shaped rib belts having ribs on one side that engage one or more -12-200840791 in the recess at the side of the drive pulley . It is equally possible to use different variants of the belt, such as a smoothing belt corresponding to the drive pulleys 1 a, 1 b, 1 C and a belt having a tooth profile on one or both sides. In addition, different types of cables can be used, such as single cable, double cable, or multiple cables. The tension members Z 1 , Z2, Z3 comprise a plurality of strands of steel wire or a mixture of aromatic polyamide fibers or Vectran fibers. At least three elevator cars 7a, 7b, 7c and three counterweights 12a, 12b, 1 2 c are suspended in tension sets Z 1 , Z 2 , Z 3 in a pulley block manner. In this case, the elevator cars 7a, 7b, 7c have at least one first and at least one second steering roller 2a, 2b, 2c, 3a, 3b, 3c fastened to the elevator cars 7a, 7b, In the area below 7c. These steering rollers 2a, 2b, 2c, 3a, 3b, 3c have one or more recesses at their outer circumference which can receive one or more tension members Z1, Z2, Z3. The steering rollers 2a, 2b, 2c, 3a, 3b, 3c are thus adapted to guide and contact the tension members Z1, Z2, Z3. Therefore, it is preferred that a lift car 7a, 7b, 7c is suspended as a lower block. In a freely selectable embodiment, the steering rollers 2a, 2b, 2c, 3a, 3b, 3c are disposed in the upper region of the elevator car 7a, 7b, 7c. In response to the above description, the elevator car 7 a, 7 b, 7 c is then suspended as an upper pulley block. The third steering wheel 4 a, 4 b, 4 c ' is disposed in the upper region of the weights 12a, 12b, 12c. It is similar to the steering rollers 2 a, 2 b, 2 c, 3 a, 3 b 3c is also suitable for receiving one or more tension members Z1, Z2, Z3. Correspondingly, the counterweights 12a, 12b, 12c are preferably suspended from the third -13-200840791 steering rollers 4a, 4b, 4c as an upper pulley block located below the associated drive means A1, A2, A3. From the first hoistway wall to the second hoistway wall, the tension members Z1, Z2, Z3 are guided by the first fixed points 5a, 5b, 5c through the first, second and second steering rollers 2a, 2b, 2c, 3a 3b, 3c, 4a, 4b, 4c and drive pulleys la, lb, lc reach the second fixed points 6a, 6b, 6c. In this case, the first fixed points 5a, 5b, 5c are arranged to oppose the associated drive means A1, A2, A3 at approximately the same hoistway height near the first or second hoistway wall. The second fixed points 6a, 6b, 6c are disposed adjacent the associated drive means A1, A2, A3 on the opposite second or first hoistway wall. The tension members Z1, Z2, Z3 extend downward from the first fixed point 5a, 5b, 5c along the first or second hoistway wall to the second turning roller 3a, 3b, 3c, and from the outside to the inside An angle of about 90° surrounds the second steering roller and is reintroduced to the first steering roller 2a, 2b, 2c. The tension members Z1, Z2, Z3 are again surrounded by the first deflection rollers 2a, 2b, 2c at an angle of about 90° from the inside to the outside, and are then introduced upwardly to the drive along the lift cars 7a, 7b, 7c. The pulleys 1 a, 1 b, 1 c are wrapped around the drive pulley at an angle of approximately 150° from the inside to the outside. Depending on the setting of the freely selectable pulleys 1 3 a, 1 3 b, 1 3 c, the surround angle can be set in the range of 90° to 180°. The tension members Z1, Z2, Z3 are then introduced down the second or first hoistway wall to the third deflection rollers 4a, 4b, 4c and are surrounded by an angle of about 180° from the outside to the inside. Around the third turning roller, and again along the second or first hoistway wall is introduced to the second fixed point 6a, 6b, 6c towards -14-200840791. As described above, the pulleys 1 3 a, 1 3 b, and 1 3 c are set as freely selectable components of one of the driving devices A2 and A3. With this setting pulley 1 13b, 13c, the circumferential angles of the tension members Z1, Z2, Z3 at the driving pulleys la, lb can be set, or increased or decreased, so that the traction force can be pulled from the driving pulley 1a, 1 b, 1 c are transmitted to the tension member Z; 1, Z 3 . Depending on the spacing between the set pulleys 1 3 a, 1 3 b, 1 3 c and the drive pulleys 1 a, 1 c , the tension members Z 1 , Z2 , Z3 and the drive units A2 , A3 and the counterweights 12a, 12b The interval between 12c or between the lift cars 7b, 7c can be additionally set. The collision-free guidance between the tension members Z1, Z2 in the hoistway between the drive pulleys 1a, 1b, 1c and the first deflection rollers 2b, 2c can thus be ensured. · A lift car 7a, 7b, 7c and associated drives A 1 , A 2 , A 3 , drive pulleys 1 a, 1 b, 1 c, steering rollers 2 b, 2 c, 3a, 3b, 3c, 4a 4b, 4c, freely selectable wheels 13a, 13b, 13c, weights 12a, 12b, 12c, tensions Z1, Z2, Z3, and fixed points 5a, 5b, 5c, 6a, 6b, 6c A lifting unit. Thus, Figure 1 shows an elevator having three liters which in turn forms a three-part group 14 . Starting from the intermediate lifting unit having the lifting compartment 7a, the adjacent lower lifting unit having the lifting compartment 7b and the driving unit A1 having the lifting unit 7c and the intermediate lifting unit respectively mirroring the lifting unit with respect to the intermediate lifting unit A2, A3 are thus located on the first or second hoistway wall which are in phase with each other, and the elevator cars 7a, 7b, 7c A1, 3a, 1c are required to be Z2, lb, A1, 7a >, Z3 2a, device 2a, the fixed-sliding members are jointly lowered, the lowering of the car is adjacent to the opposites of the 200840791. The relevant driving pulleys 1 a, 1 b, 1 c, the steering rollers 2 a, 2 b, 2 c, 3 a, 3b, 3c, 4a, 4b, 4c, setting pulleys 13a, 13b, 13c, weights 12a, 12b, 12c, tension members Z1, Z2, Z3, and fixing points 5a, 5b, 5c, 6a, 6b, 6c are also arranged in a mirror image. This mirroring configuration rule for the intermediate and adjacent lifting units applies to any desired number of lifting units that are installed in a hoistway. Another feature of the arrangement of the lifting units is that the associated drive units A1, A2, A3 and the first fixed points 5a, 5b, 5c are placed on opposite first and second hoist walls at substantially the same height . The predetermined hoistway height by means of the fixed points 5a, 5b, 5c and the drive means A1, A2, A3 is also at the same time the highest point reachable by the associated lift car 7a, 7b, 7c, as described herein The tension member in the example type cannot lift the suspension point of one of the lift cars 7a, 7b, 7c above the height of the drive pulleys la, lb, lc. The drives Al, A2, A3 and the first fixed points 5a, 5b, 5c of the intermediate and adjacent elevator cars 7a, 7b, 7c are typically placed at different hoistway heights. The elevator cars 7a, 7b, 7c can thus reach different maximum hoist heights. Correspondingly, the intermediate and adjacent elevator cars 7a, 7b, 7c are assigned to a number of different compartment sections, and the ascending and descending compartments 7a, 7b, 7c are movable in the compartment sections. The compartments ΚΙ, K2, K3 assigned to the elevator cars 7a, 7b, 7c are apparent in Fig. 1. It is apparent from this that the height of the hoistway of the drive unit in the aforementioned structure will predetermine the maximum hoistway height of the one compartment section ΚΙ, Κ2, Κ3. On the contrary, the minimum hoistway height of the compartment sections ΚΙ, Κ2, Κ3 is defined by the drive assembly -16-200840791 of the next lower lifting unit disposed below it, A1, A2, A3. In the embodiment shown here, the mirror structure of the adjacent elevation unit is such that the counterweight 12c of the adjacent upper rise 7c and the drive A2 of the next adjacent descending carriage 7b disposed below it It is placed on the same first or second wall. The deepest hoistway height reachable by the counterweight 12c is therefore limited by the drive unit A2 that is configured below and at the same level. Since the lift car 7c and the counterweight 1 2c are suspended in the same ratio of 2:1, the operating range between the drive unit A 2 and the drive unit A 3 will limit the compartment K3 of the car 7c. If the three component group 14 uses this teaching, then some of the heavy compartment sections K1, K2, K3 will be generated, with only the middle and adjacent intervals ΚΙ, K2, K3 overlapping. In a towering building having a plurality of component groups 14 arranged one above the other, all of the floors disposed in the intermediate compartment K 1 are thus served by two elevator cars. According to Fig. 2, the elevator cars 7a, 7b, 7c are composed of two rails 10 .  1, 1 0. 2 guided. The two carriage rails 1 〇 1 , 1 〇 · 2 structure connect the surface V, which in each case extends substantially through the center of gravity S of the lifts 7 a, 7 b, 7 c. In the embodiment shown here, the cars 7 a, 7 b, 7 c are eccentrically suspended. Only the arrangement of two lifting units arranged directly above and below each other is shown in this figure. However, it is clear that a configuration similar to that described above can also be constructed by a plurality of additional pairs of lifting units directly on each other. The tension members Z1, Z2, Z3 and related components in the suspension configuration (for example, the steering rollers 2 a, 2 b, 2 c ' 3 a, 3 b, 3 c, 4 a, in the middle descending machine hoistway At the same time, the two compartments of the compartments that are stacked with the counterweight are guided into a carriage lift. The expert guides the lower row 4b, 200840791 4 c and the drive pulleys 1 a, 1 b, 1 c ) are all located on the connecting surface V. On one side, wherein for the sake of clarity, the steering rollers 4a, 4b, 4c are not shown in Figure 2, ie all of the aforementioned components associated with the lift cars 7a, 7b, 7c are located Between the wall of the hoistway and the connecting plane V, or between the wall of the fourth hoistway and the connecting plane V. The third or fourth hoistway wall represents a hoistway wall having at least one hoistway door 9 and an opposing hoistway wall. The spacing y between the tension members Z1, Z2, Z3 and the connecting plane V is advantageously substantially the same. The tension members Z1, Z2, Z3 of the elevator car 7a, 7b, 7c are alternately placed on one side or the other side of the connection plane V. Therefore, the moment generated by the eccentric suspension of the elevator cars 7a, 7b, 7c has the opposite effect. In the case where the elevator cars 7a, 7b, 7c have the same level of load, and in the case where the number of the elevator cars 7a, 7b, 7c is even, the moment acting on the guide rails 1 0 · 1 , 1 0 · 2 Will increase significantly. The weights 12a, 12b, 12c are composed of two weight guide rails 11a.  l, lla. 2, lib. 1, llb. 2 guided. The weights 12a, 12b, 12c are placed at the opposite hoistway walls between the guide rails 10. 1,10. 2 is between the first or second hoistway wall. Advantageously, the weights 1 2a, 1 2b, 1 2c are suspended at their center of gravity by tension members Z1, Z2, Z3. Since the elevator cars 7a, 7b, 7c are eccentrically suspended, the weights 1 2a, 1 2b, 1 2c are laterally offset near the third and fourth hoistway walls. The drive pulleys la, lb, lc and the steering rollers 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c are parallel to the first or second hoistway wall. In the embodiment shown here, the aforementioned components are shaped such that they can receive and guide four parallel extending tension members 21, 22, 13, or at -18-200840791 drive pulleys 1a, 1b, In the case of 1 c, the tension members can be driven more. In order to be able to receive the tension members Z1, Z2, Z3, the deflection rollers 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c and the drive pulleys la, lb, 1 c have four special configurations Contact surface, in the case of a cable, such contact surfaces are designed, for example, as a plurality of grooves, or in the case of a belt, such contact surfaces are designed, for example, to be concave or toothed, or in a flat contact surface structure In this case, the contact surfaces are provided with a number of guiding shoulders. The four contact surfaces can be formed on a common roller-like base body or on four respective rollers having a common axis of rotation. Based on an understanding of the type of this embodiment, the experts will be able to think about the various variations that can be achieved according to each purpose. Thus, it would be possible to configure one to four or more individual rollers with or without spacing relative to each other on a rotating shaft. In this case, the rollers can accommodate one to four, or even receive more tension members Z1, Z2, Z3, if necessary, in the different designs, during the normal operation of the elevator, the elevator cars 7a, 7b, 7c It is placed at a landing point flush with the floor, and the car doors 8 are opened together with the hoistway doors 9 so that passengers can be transferred from the floor to the elevator cars 7a, 7b, 7c, and vice versa Car to floor. Figure 3 shows an alternative suspension configuration with a plurality of lift cars 7a, 7b, 7c suspended centrally. In this figure, only the configuration consisting of two lifting units that are directly arranged one above the other is shown. However, the expert can clearly understand that a configuration similar to the above can also be constructed by a plurality of lifting units that are directly arranged one above the other. -19- 200840791 In this case, the tension members Z 1 , Z 2, Z 3 are guided from the steering rollers and the drive pulleys ia, lb, lc located on both sides of the connection plane V. Advantageously, the suspension is symmetrically arranged relative to this connection plane V. Since the center of gravity of the suspension substantially coincides with the center of gravity S of the elevator cars 7 a, 7 b, 7 c in this case, no additional torque acts on the carriage rails 10·1, 10·2. In this central suspension of the elevator cars 7a, 7b, 7c, the associated steering rollers 2a. l, 2a. 2, 2b. l, 2b. 2, 3a. l, 3a. 2, 3b. l, 3 b · 2 and drive pulley 1 a .  1, 1 a.  2, 1 b · 1, 1 b.  The 2 series is composed of at least two rollers arranged on the left and right sides of the connection plane V. Similarly, the steering rollers 4 a, 4 b, 4 c of the weights 1 2 a, 1 2 b, and 1 2 c are also composed of two rollers disposed on the left and right sides of the connecting plane V, However, it is not shown in Figure 3 for the sake of clarity. In this example, the steering rollers 2a associated with the intermediate lift car 7a. ;l, 2a. 2, 3a. :l, 3a. 2 and drive pulleys la.  1, la. 2 is located at the first interval X from the connecting plane V, and the steering rollers 2b associated with the adjacent lower lifting carriage 7b. l, 2b. 2, 3b. l, 3b. 2 and the drive pulley lb is located at a second interval X from the connection plane V, wherein the first interval X is smaller than the second interval X. Thereby, it is possible to ensure that the tension members Z1, Z2, Z3 are guided without collision when the lift cars 7a, 7b, 7c are in the center suspension mode. In this case, the weights 12a, 12b, 12c are suspended by the center of gravity S at the tension members Zb Z2, Z3 and located in the car guide rails 10. 2, 10. 2 Between the first or second hoistway wall. Since the elevator cars 7a, 7b, 7c are now centrally suspended, the weights 12a, 12b, 12c are also located in the central region of the first and -20-200840791 second hoistway walls. Due to the central positioning of the weights 12a, 12b, 12c, the free spaces between the lateral ends of the weights 1 2 a, 1 2 b, and 1 2 c and the third and fourth well walls are increased. Big. The design freedom of the weights 1 2 a, 1 2 b, and 1 2 c is thereby increased. Thus, for example, to make better use of space, a narrower and wider counterweight 12a, 12b, 12c can be used. For a given hoistway section, the elevator car 7a, 7b, 7c is increased in width, or for a given car size, the hoistway section can be reduced.

The present invention is not limited to the embodiments disclosed above. With the understanding of the present invention, it is clear that the experts can optimize the number of specific building types. In place of the double-deck car, it may be multiple or single for the second hoistway. A single car in 2 or a duplex car with more than two cars being joined together. In addition, the number of layers assigned to the building section is freely selectable. There is no need for a number of floors in this building interval G, but this number can vary with each building interval. It is always necessary to assign only three component groups 14 to the construction interval G. The division, the five-part, or the six-component group, etc., may also be allocated to the building section G-cabin section, for example, in a three-part group, which is not necessarily symmetrically constructed. The positions of the drive units and the transition floors are adapted to the particular building conditions. Finally, the transition floors U are freely arranged for the number and position of G between the car compartment K or the number of cars in the duplex car. The following simple calculations show that a significant increase in performance is achieved due to the present invention. For U7·1 with a building association of, for example, twelve floors, it has an associated increase to , and its singular car is based on the same connection with the different ginseng. Depending on the prior art, the two lift cars each serve eleven floors, ie each lift has one 1/11 per floor. The transport factor, which is estimated by the number of floors to be serviced, and this factor represents the unit of measurement of the transport performance of the lift car in a particular floor. This will give each of the two boundary floors served by one lift car a transport factor of 1/11 and a transport factor of 2/11 in the central area consisting of ten floors (where the two compartments overlap) . According to the example of Fig. 6, the following calculation produces an intermediate building section G3: each of the elevator cars moving in the building section G3 has an associated compartment section containing eight floors. Since each floor of the building section G3 is served by two lift cars, a continuous transport coefficient of 2/8 or 1/4 is produced. This transport factor is therefore significantly higher than that of the equivalent lifting equipment of the prior art. In the second configuration of the lifting apparatus as shown in Fig. 8, the transportation coefficients of the floors of the intermediate building section G4 are calculated based on the similar considerations as described above. Each of the elevator cars moving in the building section G4 has an associated compartment section containing twelve floors. In this case, each floor of G4 in this building area is also served by two lift cars. As a result, each floor of the building section G4 has a transport factor of 2/12. In the case where the intermediate floors are served at substantially the same frequency, the boundary floor layers in this example can be significantly serviced more frequently than in the prior art lifting equipment situation.
