图1是表示本发明第1实施例的电梯设备中的吊索5的卷绕方法的图，图2是第1实施例的电梯设备的升降通道的俯视截面图。本实施例的电梯设备被构成为，电梯轿厢1在升降通道内沿着电梯轿厢用导轨16a、16b上下行驶，平衡重2在升降通道内沿着平衡重用导轨17a、17b上下行驶。此外，电梯轿厢1和平衡重2由吊索5悬吊，并且由卷扬机11驱动。在此，作为卷扬机11，使用了轴向长度大于驱动绳轮10直径的扁长形卷扬机。Fig. 1 is a diagram showing a winding method of a rope 5 in an elevator apparatus according to a first embodiment of the present invention, and Fig. 2 is a plan sectional view of a hoistway of the elevator apparatus according to the first embodiment. The elevator system of this embodiment is configured such that the elevator car 1 travels up and down along the elevator car guide rails 16a, 16b in the hoistway, and the counterweight 2 travels up and down along the counterweight guide rails 17a, 17b in the hoistway. Furthermore, the elevator car 1 and the counterweight 2 are suspended by the sling 5 and driven by the hoist 11 . Here, as the hoist 11 , a prolate hoist whose axial length is larger than the diameter of the drive sheave 10 is used.

并且，在电梯轿厢1的上部设置有悬吊滑轮8，在电梯轿厢1的下部设置有吊索固定件3，在电梯轿厢1下部的侧面设置有悬吊滑轮4。另一方面，在平衡重2的上部设置有悬吊滑轮13以及吊索固定件15。Also, a suspension pulley 8 is provided on the top of the elevator car 1 , a sling fixture 3 is provided on the bottom of the elevator car 1 , and a suspension pulley 4 is provided on the side of the elevator car 1 bottom. On the other hand, a suspension pulley 13 and a wire anchor 15 are provided on the upper portion of the counterweight 2 .

此外，在升降通道的上部设置有第1驱动绳轮侧转向滑轮9、第2驱动绳轮侧转向滑轮12以及卷扬机11的驱动绳轮10。该等第1驱动绳轮侧转向滑轮9和第2驱动绳轮侧转向滑轮12以及驱动绳轮10位于大致相同的高度，并且如图2所示，互相的铅直投影大致平行。此外，在升降通道的上部设置有2个电梯轿厢侧转向滑轮6、7以及平衡重侧转向滑轮14。在此，电梯轿厢侧转向滑轮6、7和平衡重侧转向滑轮14以及悬吊滑轮8、13的铅直投影相互大致平行，并且其铅直投影相对上述第1驱动绳轮侧转向滑轮9以及第2驱动绳轮侧转向滑轮12和驱动绳轮10大致垂直。In addition, a first driving sheave side diverting pulley 9 , a second driving sheave side diverting pulley 12 , and a driving sheave 10 of a hoist 11 are provided on the upper portion of the hoistway. The first drive sheave side deflection pulley 9, the second drive sheave side deflection pulley 12, and the drive sheave 10 are located at substantially the same height, and as shown in FIG. 2, their vertical projections are substantially parallel to each other. In addition, two deflection pulleys 6 and 7 on the elevator car side and a deflection pulley 14 on the counterweight side are provided on the upper part of the hoistway. Here, the vertical projections of the diverting pulleys 6 and 7 on the elevator car side, the diverting pulley 14 on the counterweight side, and the suspension pulleys 8 and 13 are approximately parallel to each other, and their vertical projections are opposite to the diverting pulley 9 on the first drive sheave side. And the second drive sheave side diverting pulley 12 is substantially perpendicular to the drive sheave 10 .

而且，卷扬机11被设置成，其轴与电梯门厅门的开闭方向大致平行，并且位于电梯轿厢1的铅直投影内。另外，平衡重2设置在电梯轿厢1的背部。在此，电梯轿厢1的背部是指从电梯门厅侧看位于电梯轿厢1后方的部分。Furthermore, the hoist 11 is installed such that its axis is substantially parallel to the opening and closing direction of the elevator hall door and is positioned within the vertical projection of the elevator car 1 . In addition, a counterweight 2 is provided on the back of the elevator car 1 . Here, the back of the elevator car 1 refers to a portion located behind the elevator car 1 as viewed from the elevator hall side.

以下参照图1对本实施例的电梯设备中的吊索5的卷绕方法进行说明。本实施例的电梯设备基本上采用了利用吊索固定件3、15以及悬吊滑轮8、13来悬吊电梯轿厢1以及平衡重2的3∶1的卷绕方法。如图1所示，其具体的方法是：吊索5的一端由所述电梯轿厢1下方的吊索固定件3固定，而吊索5的另一端从该吊索固定件3向大致水平的方向延伸至悬吊滑轮4，经该悬吊滑轮4转向后朝上方延伸，之后，该吊索5的该另一端向上方延伸至电梯轿厢侧转向滑轮6，并在大致水平的方向上延伸至另一个电梯轿厢侧转向滑轮7，并经该电梯轿厢侧转向滑轮7转向后朝下方延伸。之后，该吊索5该另一端延伸至电梯轿厢1上部的悬吊滑轮8，并经悬吊滑轮8转向后朝上方延伸至第1驱动绳轮侧转向滑轮9，之后卷绕到驱动绳轮10的上方，并在该驱动绳轮10上卷绕大致360°。之后，该吊索5的该另一端延伸至第2驱动绳轮侧转向滑轮12，并经转向滑轮12转向后朝下方延伸。之后，该吊索5的该另一端延伸至平衡重2上部的悬吊滑轮13，并经悬吊滑轮13转向后朝上方延伸。之后，该吊索5的该另一端延伸至平衡重侧转向滑轮14，并经转向滑轮14转向后朝下方延伸，并到达平衡重2上部的吊索固定件15，之后该吊索5的该另一端被固定在该吊索固定件15上。Next, a method of winding the rope 5 in the elevator apparatus of the present embodiment will be described with reference to FIG. 1 . The elevator equipment of the present embodiment basically adopts a 3:1 winding method in which the elevator car 1 and the counterweight 2 are suspended by using the sling fixing members 3, 15 and the suspension pulleys 8, 13. As shown in Figure 1, its specific method is: one end of the sling 5 is fixed by the sling fixing part 3 below the elevator car 1, and the other end of the sling 5 is substantially horizontal from the sling fixing part 3. The direction extends to the suspension pulley 4, and after the suspension pulley 4 is turned, it extends upwards. After that, the other end of the sling 5 extends upwards to the elevator car side diverting pulley 6, and in a substantially horizontal direction Extend to another elevator car side diverting pulley 7, and extend downwards after turning the elevator car side diverting pulley 7. Afterwards, the other end of the sling 5 extends to the suspension pulley 8 on the upper part of the elevator car 1, and after being turned by the suspension pulley 8, it extends upward to the first drive sheave side deflection pulley 9, and then is wound to the drive rope The top of the pulley 10, and winds approximately 360° on the drive sheave 10. Thereafter, the other end of the sling 5 extends to the second drive sheave side deflection pulley 12, is deflected by the deflection pulley 12, and extends downward. Afterwards, the other end of the sling 5 extends to the suspension pulley 13 on the top of the balance weight 2, and extends upward after being turned by the suspension pulley 13. Afterwards, the other end of the sling 5 extends to the counterweight side turning pulley 14, and extends downward after being turned by the turning pulley 14, and reaches the sling fixing part 15 on the top of the counterweight 2, and then the sling 5 The other end is fixed on the sling fixing part 15 .

在此，本实施例中的吊索5在驱动绳轮10上卷绕方法如图9所示，3根吊索5在驱动绳轮面10a上螺旋状地卷绕大致360°后，卷绕初始位置和卷绕结束位置仍然朝着轴向偏差，因此，吊索5相互之间不会接触。此外，吊索5通过第1驱动绳轮侧转向滑轮9后卷绕到驱动绳轮10的上方，并在该驱动绳轮10上卷绕大致360°，之后通过第2驱动绳轮侧转向滑轮12朝下方转向。也就是说，吊索5在驱动绳轮10、第1驱动绳轮侧转向滑轮9以及第2驱动绳轮侧转向滑轮12上的卷绕方向为相同方向，也就是说，吊索5的卷绕方向为顺时针方向。Here, the method of winding the sling 5 around the driving sheave 10 in this embodiment is as shown in FIG. The initial position and the winding end position are still axially offset, so that the slings 5 do not come into contact with each other. In addition, the sling 5 passes through the first driving sheave side diverting pulley 9, is wound up above the driving sheave 10, is wound around the driving sheave 10 for approximately 360°, and then passes through the second driving sheave side diverting pulley. 12 turns downwards. That is to say, the winding direction of the sling 5 on the driving sheave 10, the first driving sheave side diverting pulley 9, and the second driving sheave side diverting pulley 12 is the same direction, that is, the winding direction of the sling 5 is the same. The winding direction is clockwise.

根据上述本实施例，由于驱动绳轮10上的吊索5卷绕角大致为360°，因此能够充分确保动力传递，并且能够缩小卷扬机11的驱动绳轮10的直径，其结果，可以使用小转矩的卷扬机11。此外，由于采用了3∶1卷绕方式，垂直负载分散为3部分，其结果，可以使用小转矩的卷扬机11。如此，在本实施例中，由于可以采用小转矩的卷扬机11，因此能够实现卷扬机11自身的小型化，能够节省升降通道的空间。According to the above-mentioned present embodiment, since the winding angle of the sling 5 on the driving sheave 10 is approximately 360°, power transmission can be sufficiently ensured, and the diameter of the driving sheave 10 of the hoisting machine 11 can be reduced. Torque winch 11. In addition, since the 3:1 winding method is adopted, the vertical load is distributed into three parts, and as a result, the hoist 11 with a small torque can be used. In this way, in this embodiment, since the winch 11 with small torque can be used, the size of the winch 11 itself can be realized, and the space of the lifting passage can be saved.

另外，由于驱动绳轮10上的吊索5卷绕角大致为360°，因此不需要为了得到充分的动力传递而提高驱动绳轮10的位置，也不需要在驱动绳轮10的下部附近另外设置转向滑轮。在此，由于不需要提高驱动绳轮10的位置，因此有助于降低升降通道的高度以及节省升降通道的空间。并且，由于不需要设置多余的滑轮，所以有助于节省升降通道的空间。In addition, since the winding angle of the sling 5 on the driving sheave 10 is approximately 360°, it is not necessary to raise the position of the driving sheave 10 in order to obtain sufficient power transmission, and it is not necessary to separate the driving sheave 10 near the lower portion of the driving sheave 10. Set the steering pulley. Here, since there is no need to raise the position of the driving sheave 10, it helps to reduce the height of the elevator passage and save the space of the elevator passage. And, since there is no need to set extra pulleys, it helps to save the space of the lifting passage.

此外，由于不需要设置多余的滑轮，所以减少了吊索5的弯曲次数，其结果，具有提高吊索5使用寿命的效果。而且，由于吊索5在驱动绳轮10、第1驱动绳轮侧转向滑轮9以及第2驱动绳轮侧转向滑轮12上的卷挂方向是顺时针方向，所以即使缩小绳轮的半径，也能够确保延长吊索5的使用寿命。In addition, since there is no need to provide extra pulleys, the number of times of bending of the sling 5 is reduced, and as a result, there is an effect of improving the service life of the sling 5 . Moreover, since the winding direction of the sling 5 on the driving sheave 10, the first driving sheave side diverting pulley 9, and the second driving sheave side diverting pulley 12 is clockwise, even if the radius of the sheave is reduced, the The service life of the sling 5 can be ensured to be extended.

图3是表示本发明第2实施例的电梯设备的吊索5的卷绕方法的图，图4是第2实施例的电梯设备中的升降通道的俯视截面图。在本实施例的电梯设备中，与第1实施例的不同之处在于，在电梯轿厢1的地板下方的侧面设置有一对悬吊滑轮8、8a，在升降通道的上部，在不会对电梯轿厢1以及平衡重2的行驶带来妨碍的场所设置有吊索固定件3、15。也就是说，在本实施例中采用的是2∶1的卷绕方法，由于与1∶1的卷绕方法相比，可以使用小转矩的卷扬机11，因此能够实现卷扬机11的小型化，其结果，能够节省升降通道的空间。Fig. 3 is a diagram showing a winding method of the rope 5 of the elevator equipment according to the second embodiment of the present invention, and Fig. 4 is a top sectional view of the hoistway in the elevator equipment according to the second embodiment. In the elevator equipment of this embodiment, the difference from the first embodiment is that a pair of suspension pulleys 8, 8a are arranged on the side under the floor of the elevator car 1, and on the upper part of the hoistway, there is no opposite Rope fixing members 3 and 15 are installed at places where the running of the elevator car 1 and the counterweight 2 are obstructed. That is to say, what adopt in the present embodiment is the winding method of 2: 1, because compared with the winding method of 1: 1, can use the hoisting machine 11 of small torque, therefore can realize the miniaturization of hoisting machine 11, As a result, the space of the hoistway can be saved.

此外，如图4所示，在本实施例中，与第1实施例的不同之处在于，第1驱动绳轮侧转向滑轮9、第2驱动绳轮侧转向滑轮12以及驱动绳轮10相对于电梯门厅门的开闭方向倾斜。通过如此设置，即使采用2∶1的卷绕方法，也能够将卷扬机11设置在电梯轿厢1的垂直投影内，并且能够将平衡重2设置在电梯轿厢1的背部。In addition, as shown in FIG. 4 , in this embodiment, the difference from the first embodiment is that the first drive sheave side deflection pulley 9, the second drive sheave side deflection pulley 12, and the drive sheave 10 are opposite to each other. It is inclined to the opening and closing direction of the elevator hall door. With this arrangement, even with a 2:1 winding method, the winch 11 can be arranged in the vertical projection of the elevator car 1 and the counterweight 2 can be arranged on the back of the elevator car 1 .

并且，在本实施例中，与第1实施例一样，第1驱动绳轮侧转向滑轮9和第2驱动绳轮侧转向滑轮12大致直线状设置，并且在两者之间设置了驱动绳轮10以及卷扬机11，因此，与第1实施例一样，垂直负载几乎不作用在驱动绳轮10上。此外，不需要进行将驱动绳轮10的位置朝上方移动以调节吊索5卷绕角的作业。因此，能够取得节省升降通道的空间的效果，即，能够取得即使在空间有限的升降通道内也能够设置卷扬机11的效果。In addition, in this embodiment, as in the first embodiment, the first drive sheave side diverting pulley 9 and the second driving sheave side diverting pulley 12 are arranged in a substantially straight line, and a drive sheave is provided between them. 10 and hoisting machine 11, therefore, like the first embodiment, the vertical load hardly acts on the drive sheave 10. In addition, it is not necessary to perform the work of moving the position of the drive sheave 10 upward to adjust the winding angle of the wire rope 5 . Therefore, it is possible to obtain the effect of saving the space of the hoistway, that is, to obtain the effect that the hoist 11 can be installed even in the hoistway with limited space.

此外，本实施例中的驱动绳轮面10a的形状如图10所示，驱动绳轮10的半径在轴向端部较小而在轴向中心则较大。并且，驱动绳轮面10a形成为曲面，具体来说大致为旋转的椭圆形状或者大致为旋转的圆弧状。通过使用上述的驱动绳轮10，使得绳轮5进入驱动绳轮面10a的一侧容易向卷扬机11相反侧滑动，而从驱动绳轮面10a出来的一侧容易向卷扬机11侧滑动。因此，吊索5彼此之间不易发生接触，从而能够获得防止吊索5发生异常磨耗的效果。In addition, the shape of the driving sheave surface 10a in this embodiment is as shown in FIG. 10, and the radius of the driving sheave 10 is smaller at the axial ends and larger at the axial center. Furthermore, the drive sheave surface 10a is formed into a curved surface, specifically, a substantially rotating ellipse or substantially rotating arc. By using the above-mentioned driving sheave 10, the side where the sheave 5 enters the driving sheave surface 10a is easy to slide to the opposite side of the hoisting machine 11, and the side coming out of the driving sheave surface 10a is easy to slide to the hoisting machine 11 side. Therefore, it is difficult for the slings 5 to come into contact with each other, and an effect of preventing abnormal wear of the slings 5 can be obtained.

图5是表示本发明第3实施例的电梯设备的吊索5的卷绕方法的图，图6是第3实施例的电梯设备的升降通道的俯视截面图。本实施例的电梯设备与第1实施例大致相同，也使用3∶1的卷绕方法，但是具体的吊索卷绕方法有所不同，以下参照图5进行说明。Fig. 5 is a diagram showing a winding method of the rope 5 of the elevator equipment according to the third embodiment of the present invention, and Fig. 6 is a top sectional view of the hoistway of the elevator equipment according to the third embodiment. The elevator equipment of this embodiment is substantially the same as that of the first embodiment, and also uses the winding method of 3:1, but the specific winding method of the sling is different, and will be described below with reference to FIG. 5 .

如图所示，吊索5的一端由电梯轿厢1下部的吊索固定件3固定，而吊索5的另一端从该吊索固定件3向大致水平的方向延伸，经过悬吊滑轮4转向后朝上方延伸。之后，吊索5的该另一端向上方延伸至电梯轿厢侧转向滑轮6，并且沿大致水平的方向延伸至另一个电梯轿厢侧转向滑轮7，经过该电梯轿厢侧转向滑轮7转向后朝下方延伸。进而，该吊索5的该另一端通过电梯轿厢1上部的悬吊滑轮8转向而朝上方延伸，通过驱动绳轮侧转向滑轮18后被卷挂到驱动绳轮10的上方，在该驱动绳轮10上大致卷绕450°后转向朝下方延伸。然后，吊索5的该另一端延伸至平衡重2上部的悬吊滑轮13，经转向后朝上方延伸。之后，该吊索5的该另一端经过平衡重侧转向滑轮14转向后朝下方延伸到达平衡重2上部的吊索固定件15，并被固定在该吊索固定件15上。As shown in the figure, one end of the sling 5 is fixed by the sling fixing part 3 at the lower part of the elevator car 1, and the other end of the sling 5 extends from the sling fixing part 3 to a substantially horizontal direction and passes through the suspension pulley 4. Turn and extend upwards. Afterwards, the other end of the sling 5 extends upwards to the diverting pulley 6 on the side of the elevator car, and extends to another diverting pulley 7 on the side of the elevator car in a substantially horizontal direction. extend downward. Furthermore, the other end of the sling 5 is turned upward by the suspension pulley 8 on the upper part of the elevator car 1, and extends upward, passes through the drive sheave side deflection pulley 18, and is wound to the top of the drive sheave 10. The sheave 10 turns and extends downward after being wound approximately 450°. Then, the other end of the sling 5 extends to the suspension pulley 13 on the top of the balance weight 2, and extends upward after turning. Afterwards, the other end of the sling 5 extends downwards to the sling fixing part 15 on the top of the counterweight 2 after being turned by the counterweight side turning pulley 14 , and is fixed on the sling fixing part 15 .

如此，驱动绳轮侧转向滑轮18位于电梯轿厢的悬吊滑轮8与驱动绳轮10之间，而驱动绳轮10兼具上述第1实施例中的第2驱动绳轮侧转向滑轮12的作用。由于转向滑轮数量减少，所以能够相应地节省悬架(overhead)所需的空间。此外，如果受物理性条件的限制，而不能如第1实施例那样在第1驱动绳轮侧转向滑轮9与第2驱动绳轮侧转向滑轮12之间设置驱动绳轮10时，则采用本实施例特别有效。并且，与上述第1实施例不同，在本实施例中，由于驱动绳轮10上的吊索5卷绕角大致为450°，所以能够进行更为有效的动力传递。此外，本实施例的卷扬机11被设置成其铅直投影与电梯轿厢1以及平衡重2均重叠。In this way, the driving sheave side diverting pulley 18 is located between the suspension pulley 8 and the driving sheave 10 of the elevator car, and the driving sheave 10 also has the functions of the second driving sheave side diverting pulley 12 in the above-mentioned first embodiment. effect. As the number of deflection pulleys is reduced, the space required for the overhead can be correspondingly saved. In addition, if limited by physical conditions, the driving sheave 10 cannot be set between the first driving sheave side diverting pulley 9 and the second driving sheave side diverting pulley 12 as in the first embodiment, then this method is adopted. Examples are particularly effective. In addition, unlike the above-mentioned first embodiment, in this embodiment, since the winding angle of the rope 5 on the drive sheave 10 is approximately 450°, more efficient power transmission can be performed. In addition, the hoist 11 of this embodiment is set so that its vertical projection overlaps with both the elevator car 1 and the counterweight 2 .

此外，本实施例的驱动绳轮10的半径在卷扬机11的主体侧较小而在主体侧的相反侧较大，具体来说如图11所示，具有大致为圆锥台形状的驱动绳轮面10a。因此，在相对于吊索5的驱动绳轮面10a的面压大致一定时，由于吊索5越接近卷扬机11的主体侧就越容易滑动，因此吊索5彼此之间不易发生接触，从而能够获得防止异常磨耗发生的效果。In addition, the radius of the driving sheave 10 of this embodiment is smaller on the side of the main body of the hoisting machine 11 and larger on the opposite side of the main body. Specifically, as shown in FIG. 10a. Therefore, when the surface pressure against the driving sheave surface 10a of the sling 5 is substantially constant, the sling 5 tends to slide as it gets closer to the main body side of the hoist 11, so the slings 5 are less likely to come into contact with each other. The effect of preventing abnormal wear from occurring is obtained.

图7是表示本发明第4实施例的电梯设备的吊索5的卷绕方法的图，图8是第4实施例的电梯设备中的升降通道的俯视截面图。本实施例的电梯设备与第2实施例相同，采用了2∶1的卷绕方法，而其与上述实施例的不同之处在于，其平衡重2设置在电梯轿厢1的左侧部分。在此，电梯轿厢1的左侧部分是指从电梯门厅看位于电梯轿厢1左边的部分。此外，驱动绳轮10兼具上述第1实施例中的第1驱动绳轮侧转向滑轮9的作用，其优点是能够将卷扬机11设置在便于维修保养的位置上。Fig. 7 is a diagram showing a winding method of the rope 5 of the elevator equipment according to the fourth embodiment of the present invention, and Fig. 8 is a top sectional view of the hoistway in the elevator equipment according to the fourth embodiment. The elevator equipment of the present embodiment is the same as the second embodiment, adopting the winding method of 2:1, and its difference from the above-mentioned embodiment is that its counterweight 2 is arranged on the left side part of the elevator car 1. Here, the left part of the elevator car 1 refers to the part located on the left side of the elevator car 1 as viewed from the elevator lobby. In addition, the driving sheave 10 also functions as the first driving sheave side diverting pulley 9 in the above-mentioned first embodiment, which has the advantage of being able to install the winch 11 at a position convenient for maintenance.

此外，本实施例中的驱动绳轮10的表面实施了喷丸处理或者滚花处理，或者实施了镀镍或者镀铬等的镀敷处理等。当然，也可以在实施了上述喷丸处理或者滚花处理后，进一步实施镀敷处理。In addition, the surface of the driving sheave 10 in this embodiment is subjected to shot blasting or knurling treatment, or plating treatment such as nickel plating or chrome plating. Of course, after performing the above-mentioned shot peening treatment or knurling treatment, plating treatment may be further performed.

在上述第1至第4实施例中，卷绕角被设置成大致360°的角度或者超过360°的角度，例如被设置成360°加大致90°的大致450°的角度，但只要至少在大致360°以上时，则即使采用小直径的驱动绳轮，也能够有效地进行动力传递。此外，在需要进一步提高动力传递的效率时，可以采用表面涂敷树脂的吊索5。In the above-mentioned first to fourth embodiments, the winding angle is set to an angle of approximately 360° or an angle exceeding 360°, for example, an angle of approximately 450° which is 360° plus approximately 90°, but as long as at least When the angle is approximately 360° or more, power transmission can be efficiently performed even if a small-diameter driving sheave is used. In addition, when the efficiency of power transmission needs to be further improved, the surface-coated sling 5 can be used.

此外，在上述第1～4实施例中均采用了通过电梯轿厢1上部或者下部的悬吊滑轮悬吊电梯轿厢1的方式。因此，与作为吊索固定件使用垂直方向的吊索固定杆(thimble rod)将吊索的端部固定在电梯轿厢上，并且采用1∶1卷绕方法的现有技术相比，在悬架方向的限制少。此外，在上述第1、3实施例中，在电梯轿厢1的下部设置有吊索固定件3，但由于该吊索固定件3被设置在水平方向上，因此能够抑制升降通道的高度方向的尺寸增加。In addition, in the first to fourth embodiments above, the elevator car 1 is suspended by the suspension pulleys on the upper or lower part of the elevator car 1 . Therefore, compared with the prior art that uses a vertical thimble rod as a sling fixing member to fix the end of the sling on the elevator car and adopts a 1:1 winding method, the thimble rod in the suspension There are few restrictions on the direction of the rack. In addition, in the above-mentioned first and third embodiments, the sling fixing part 3 is provided at the lower part of the elevator car 1, but since the sling fixing part 3 is arranged in the horizontal direction, it is possible to restrain the height direction of the hoistway. size increases.
