技術分野  Technical field
[0001] この発明は、駆動装置を搭載したかごが昇降路内を昇降される自走式のエレべ一 タ装置に関するものである。  TECHNICAL FIELD [0001] The present invention relates to a self-propelled elevator apparatus in which a car equipped with a drive device is moved up and down in a hoistway.
背景技術  Background art
[0002] 従来、昇降路の省スペース化を図るために、力ごの下部に駆動装置を搭載した自 走式のエレベータ装置が提案されている。このような従来のエレベータ装置では、互 いに平行な回転軸を有する第 1のシーブ及び第 2のシーブがかごの下部に設けられ ている。各シーブの回転軸は、それぞれ水平に配置されている。かごは、各シーブに それぞれ連続的に巻き掛けられた第 1のロープ及び第 2のロープにより吊り下げられ ている。各シーブの一方は、駆動装置の駆動力により回転される。かごは、駆動装置 の駆動力によってシーブが回転されることにより、昇降路内を昇降される（特許文献 1 参照)。  Conventionally, in order to save the space of the hoistway, a self-propelled elevator apparatus in which a driving device is mounted on the lower part of the force cage has been proposed. In such a conventional elevator apparatus, a first sheave and a second sheave having rotating shafts parallel to each other are provided at the lower part of the car. The rotation shaft of each sheave is arranged horizontally. The car is suspended by a first rope and a second rope that are continuously wound around each sheave. One of the sheaves is rotated by the driving force of the driving device. The car is moved up and down in the hoistway by rotating the sheave by the driving force of the driving device (see Patent Document 1).

I'll end up. This makes it difficult to save space in the hoistway, resulting in a large elevator device.

The drive sheave 10 is wound with the first and second main ropes 5 and 6 from the respective pulleys 11 and 12 for hanging the car. Further, the first and second main ropes 5 and 6 from the drive sheave 10 are respectively led to the lower side of the car 2 by the winding pulleys 13 and 14.
[0012] 即ち、各第 1の主索 5は、上端部 5aから、一方のかご吊り用プーリ 11、駆動シーブ 1 0及び一方の巻き付け用プーリ 13の順に巻き掛けられ、下端部 5bに至っている。ま た、各第 2の主索 6は、上端部 6aから、他方のかご吊り用プーリ 12、駆動シーブ 10及 び他方の巻き付け用プーリ 14の順に巻き掛けられ、下端部 6bに至っている。  That is, each first main rope 5 is wound from the upper end portion 5a in order of one car suspension pulley 11, the drive sheave 10 and one winding pulley 13 to the lower end portion 5b. .

Each of the car suspension pulleys 11 and 12 is arranged symmetrically with respect to the rotation axis of the drive sheave 10. Further, the winding pulleys 13 and 14 are also arranged symmetrically with respect to the rotational axis of the drive sheave 10 (FIG. 2). As a result, the load that the rotating shaft of the drive sheave 10 receives from each first main rope 5 and the load that the rotating shaft of the drive sheave 10 receives from each second main rope 6 cancel each other. The small size is designed.
[0014] また、昇降路 1の垂直投影面内において、一方のかご吊り用プーリ 11の中心及び 一方の巻き付け用プーリ 13の中心のそれぞれと駆動シーブ 10の回転軸とを結ぶ 2 本の直線がなす角度は、鋭角になっている。さらに、昇降路 1の垂直投影面内にお いて、他方のかご吊り用プーリ 12の中心及び他方の巻き付け用プーリ 14の中心のそ れぞれと駆動シーブ 10の回転軸とを結ぶ 2本の直線がなす角度も、鋭角になってい る（図 2)。これにより、第 1及び第 2の主索 5, 6のそれぞれの駆動シーブ 10に対する 巻き付け角が確保される。  Further, in the vertical projection plane of the hoistway 1, two straight lines connecting the center of one car suspension pulley 11 and the center of one winding pulley 13 and the rotation shaft of the drive sheave 10 are formed. The angle formed is an acute angle. Further, in the vertical projection plane of the hoistway 1, the two centers connecting the center of the other car suspension pulley 12 and the center of the other winding pulley 14 and the rotation shaft of the drive sheave 10 are connected. The angle formed by the straight line is also acute (Figure 2). As a result, the wrapping angles of the first and second main ropes 5 and 6 with respect to the drive sheave 10 are secured.
[0015] 第 1の主索 5には、第 1の主索 5に張力を与えるための張力手段である第 1のおもり 15が吊り下げられている。第 1のおもり 15は、第 1の主索 5の下端部 5bに設けられて いる。また、第 2の主索 6には、第 2の主索 6に張力を与えるための張力手段である第 2のおもり 16が吊り下げられている。第 2のおもり 16は、第 2の主索 6の下端部 6bに 設けられている。この例では、第 1及び第 2のおもり 15, 16は、第 1及び第 2の主索 5 , 6のそれぞれに独立して設けられている。 [0015] The first main rope 5 has a first weight which is a tension means for applying tension to the first main rope 5. 15 is suspended.

[0016] 図 3は、図 1のエレベータ装置を示す側面図である。また、図 4は、図 3のかご 4の下 部を示す拡大図である。図に示すように、一方のかご吊り用プーリ 11及び一方の卷 き付け用プーリ 13のかご 4に対する上下方向の位置は、第 1の主索 5の駆動シーブ 1 0に巻き掛けられた部分が水平になるように調整されている。即ち、かご吊り用プーリ 11及び巻き付け用プーリ 13は、かご吊り用プーリ 11の下部の高さと巻き付け用ブー リ 13の上部の高さとがー致するように配置されて 、る。  FIG. 3 is a side view showing the elevator apparatus of FIG. FIG. 4 is an enlarged view showing the lower part of the car 4 in FIG. As shown in the figure, the vertical position of one car suspension pulley 11 and one brazing pulley 13 with respect to the car 4 is such that the portion wrapped around the drive sheave 10 of the first main rope 5 is 10 It is adjusted to be horizontal. That is, the car suspension pulley 11 and the winding pulley 13 are arranged so that the height of the lower part of the car suspension pulley 11 and the height of the upper part of the winding pulley 13 coincide.
[0017] また、他方のかご吊り用プーリ 12及び他方の巻き付け用プーリ 14のかご 4に対する 上下方向の位置は、第 2の主索 6の駆動シーブ 10に巻き掛けられた部分が水平にな るように調整されている。即ち、力ご吊り用プーリ 12及び巻き付け用プーリ 14は、力ご 吊り用プーリ 12の下部の高さと巻き付け用プーリ 14の上部の高さとがー致するように 配置されている。  [0017] The vertical position of the other car suspension pulley 12 and the other winding pulley 14 with respect to the car 4 is such that the portion of the second main rope 6 wound around the drive sheave 10 is horizontal. Have been adjusted so that. That is, the force suspension pulley 12 and the winding pulley 14 are arranged such that the height of the lower portion of the force suspension pulley 12 matches the height of the upper portion of the winding pulley 14.
[0018] なお、駆動吊り下げ装置 17は、主索体 7、卷上機 8、一対のかご吊り用プーリ 11, 1 2及び一対の巻き付け用プーリ 13, 14を有している。  [0018] The drive suspension device 17 includes a main rope body 7, a lifting machine 8, a pair of car suspension pulleys 11, 12 and a pair of winding pulleys 13, 14.
[0019] 次に、動作について説明する。かご 4を上昇させる場合には、図 2に示すように、駆 動シーブ 10を反時計回り（各かご吊り用プーリ 11, 12から駆動シーブ 10側へ第 1及 び第 2の主索 5, 6を引く方向、 A方向）に回転させる。これにより、第 1及び第 2の主 索 5, 6は、各かご吊り用プーリ 11, 12から駆動シーブ 10へそれぞれ移動され (即ち 、 B方向へ移動され)、駆動シーブ 10から各巻き付け用プーリ 13, 14へそれぞれ移 動される（即ち、 C方向へ移動される）。これにより、力ご 4が上昇する。  Next, the operation will be described. When raising the car 4, as shown in Fig. 2, turn the drive sheave 10 counterclockwise (from each car suspension pulley 11, 12 to the drive sheave 10 side, the first and second main ropes 5, Rotate in the direction to pull 6 (direction A). As a result, the first and second main ropes 5 and 6 are moved from the respective car suspension pulleys 11 and 12 to the drive sheave 10 (that is, moved in the direction B), and each winding pulley is driven from the drive sheave 10. Moved to 13 and 14, respectively (ie moved in direction C). As a result, the force 4 increases.
[0020] かご 4を下降させる場合には、上記と反対方向へ駆動シーブ 10を回転させる。これ により、上記と逆の動作を行い、かご 4が下降する。  [0020] When the car 4 is lowered, the drive sheave 10 is rotated in the opposite direction. As a result, the operation reverse to the above is performed, and the car 4 is lowered.
[0021] ここで、かご 4を移動させるために卷上機 8が発生する駆動トルク Tqは、以下の式（ 1)により表される。 [0022] Tq= (Wc + CAP) 'D〜（l) Here, the driving torque Tq generated by the lifting machine 8 to move the car 4 is expressed by the following equation (1). [0022] Tq = (Wc + CAP) 'D ~ (l)
[0023] なお、 Wcはかご 4の質量、 CAPはかご 4の積載質量、 Dは駆動シーブ 10の直径で ある。  [0023] Wc is the mass of the car 4, CAP is the loading mass of the car 4, and D is the diameter of the drive sheave 10.
[0024] 式（1)から分力るように、力ご 4の質量 Wcと積載質量 CAPとが大きくなると、駆動ト ルク Tqが大きくなる。また、ガイドレール 2, 3には、駆動シーブ 10の回転により、水平 方向の押圧力がかご 4から与えられるので、駆動トルク Tqが大きくなると、かご 4とガイ ドレール 2, 3との接触抵抗が大きくなり、カゝご 4の走行抵抗が大きくなる。このようなこ とから、この実施の形態 1では、かご 4の積載量が比較的小さいエレベータ装置とす るのが望ましい。  [0024] As shown in the equation (1), when the mass Wc of the force 4 and the loading mass CAP are increased, the driving torque Tq is increased. Further, since the guide rails 2 and 3 are given horizontal pressing force from the car 4 due to the rotation of the drive sheave 10, the contact resistance between the car 4 and the guide rails 2 and 3 increases as the driving torque Tq increases. Increased, the running resistance of the basket 4 increases. For this reason, in the first embodiment, it is desirable to use an elevator apparatus in which the load capacity of the car 4 is relatively small.
[0025] このようなエレベータ装置では、鉛直方向に沿って配置された回転軸を中心に回転 される駆動シーブ 10を有する卷上機 8と、各上端部 5a, 6aからの第 1及び第 2の主 索 5, 6を水平方向へ導く一対のかご吊り用プーリ 11, 12と、各かご吊り用プーリ 11, 12から駆動シーブ 10に巻き掛けられた第 1及び第 2の主索 5, 6をかご 4の下方へ導 く一対の巻き付け用プーリ 13, 14とがかご 4にそれぞれ設けられているので、昇降路 1の水平方向についての寸法を維持したまま、駆動シーブ 10をかご 4に対して水平 に配置することができ、かご 4全体の高さ方向についての寸法も小さくすることができ る。これにより、昇降路 1の省スペース化を図ることができる。  [0025] In such an elevator apparatus, the hoisting machine 8 having the drive sheave 10 rotated around the rotation shaft arranged along the vertical direction, and the first and second from the upper end portions 5a and 6a, respectively. A pair of car suspension pulleys 11 and 12 for guiding the main ropes 5 and 6 in the horizontal direction, and the first and second main ropes 5 and 6 wound around the drive sheave 10 from the respective pulleys 11 and 12 for car suspension. Since a pair of winding pulleys 13 and 14 and a cage 4 for guiding the car 4 to the lower side of the car 4 are respectively provided on the car 4, the drive sheave 10 is moved relative to the car 4 while maintaining the horizontal dimension of the hoistway 1. Can be arranged horizontally, and the overall height of the car 4 can be reduced. Thereby, space saving of the hoistway 1 can be achieved.
[0026] また、各かご吊り用プーリ 11, 12は、駆動シーブ 10の回転軸に関して対称に配置 され、各巻き付け用プーリ 13, 14も、駆動シーブ 10の回転軸に関して対称に配置さ れているので、駆動シーブ 10の回転軸が第 1及び第 2の主索 5, 6のそれぞれから受 ける荷重を相殺することができる。これにより、駆動シーブ 10の回転軸にかかる負荷 を軽減することができ、卷上機 8の小形ィ匕を図ることができる。  [0026] Each of the car suspension pulleys 11 and 12 is arranged symmetrically with respect to the rotation axis of the drive sheave 10, and each of the winding pulleys 13 and 14 is also arranged symmetrically with respect to the rotation axis of the drive sheave 10. Therefore, the load received by the rotating shaft of the drive sheave 10 from each of the first and second main ropes 5 and 6 can be offset. Thereby, the load applied to the rotating shaft of the drive sheave 10 can be reduced, and the small size of the lifting machine 8 can be achieved.
[0027] また、第 1及び第 2の主索 5, 6には、第 1及び第 2のおもり 15, 16により張力が与え られているので、駆動シーブ 10、各かご吊り用プーリ 11, 12及び各巻き付け用ブー リ 13, 14のそれぞれからの第 1及び第 2の主索 5, 6の外れを防止することができる。 また、第 1及び第 2の主索 5, 6に対する駆動シーブ 10の滑りの防止を図ることができ 、卷上機 8の駆動力を第 1及び第 2の主索 5, 6に効率良く伝達することができる。  [0027] Since the first and second main ropes 5 and 6 are tensioned by the first and second weights 15 and 16, the driving sheave 10 and the pulleys 11 and 12 for suspending the car are used. In addition, it is possible to prevent the first and second main ropes 5 and 6 from coming off from the winding wraps 13 and 14, respectively. In addition, it is possible to prevent the drive sheave 10 from slipping with respect to the first and second main ropes 5 and 6, and to efficiently transmit the driving force of the lifting machine 8 to the first and second main ropes 5 and 6. can do.
[0028] また、第 1及び第 2のおもり 15, 16が第 1及び第 2の主索 5, 6に吊り下げられている ので、簡単な構成で第 1及び第 2の主索 5, 6に張力を与えることができる。 [0028] The first and second weights 15, 16 are suspended from the first and second main ropes 5, 6. Therefore, tension can be applied to the first and second main ropes 5 and 6 with a simple configuration.
[0029] また、第 1及び第 2のおもり 15, 16は、第 1及び第 2の主索 5, 6の各下端部 5b, 6b に独立して設けられているので、例えば各主索 5, 6の伸びに差が生じた場合であつ ても、各主索 5, 6のそれぞれに独立して張力を与えることができ、第 1及び第 2の主 索 5, 6の各張力に偏りが生じることを防止することができる。  [0029] Since the first and second weights 15, 16 are provided independently at the lower ends 5b, 6b of the first and second main ropes 5, 6, for example, each main rope 5 Even if there is a difference in the elongation between the main ropes 5 and 6, tension can be applied to each of the main ropes 5 and 6 independently. Can be prevented.
[0030] また、卷上機 8がかご 4の下部に設けられているので、昇降路 1のオーバヘッド寸法 を/ J、さくすることができる。  [0030] Further, since the hoisting machine 8 is provided at the lower part of the car 4, the overhead dimension of the hoistway 1 can be reduced by / J.
[0031] なお、上記の例では、互いに独立した第 1及び第 2のおもり 15, 16により、第 1及び 第 2の主索 5, 6のそれぞれに張力が与えられるようになつている力 第 1及び第 2の 主索 5, 6が接続された共通のおもり（張力手段）により、第 1及び第 2の主索 5, 6のそ れぞれに張力を与えるようにしてもよい。また、昇降路 1内に設けた例えばばね等の 弾性体 (張力手段)で各主索 5, 6を引くことにより、第 1及び第 2の主索 5, 6のそれぞ れに張力を与えるようにしてもょ 、。  [0031] In the above example, the first and second weights 15, 16 independent of each other are the forces that apply tension to the first and second main ropes 5, 6 respectively. Tension may be applied to each of the first and second main ropes 5 and 6 by a common weight (tensioning means) to which the first and second main ropes 5 and 6 are connected. Also, tension is applied to each of the first and second main ropes 5, 6 by pulling the main ropes 5, 6 with an elastic body (tensioning means) such as a spring provided in the hoistway 1. Even so,

Further, the car suspension pulley 12 and the winding pulley 14 are arranged between the other car suspension pulley 12 'and the other winding pulley 14' in the vertical projection plane of the hoistway 1. The
[0041] 第 1の主索 5'の下端部 5' bには、第 1の主索 5'に張力を与えるための第 1のおもり  [0041] The lower end 5 'b of the first main rope 5' has a first weight for applying tension to the first main rope 5 '.
(張力手段） 15 'が吊り下げられている。第 2の主索 6'の下端部 6' bには、第 2の主索 6'に張力を与えるための第 2のおもり（張力手段） 16'が吊り下げられている。  (Tensioning means) 15 'is suspended. A second weight (tensioning means) 16 'for applying tension to the second main rope 6' is suspended from the lower end 6'b of the second main rope 6 '.
[0042] なお、他方の駆動吊り下げ装置 21においても、第 1の主索 5'の駆動シーブ 10'に 巻き掛けられた部分が水平になるように、一方のかご吊り用プーリ 11 '及び一方の卷 き付け用プーリ 13'のかご 4に対する上下方向の位置が調整され、第 2の主索 6'の 駆動シーブ 10'に巻き掛けられた部分が水平になるように、他方のかご吊り用プーリ 12'及び他方の巻き付け用プーリ 14'のかご 4に対する上下方向の位置が調整され ている（図 6)。  [0042] It should be noted that also in the other drive suspension device 21, one of the car suspension pulleys 11 'and one of the ones so that the portion wound around the drive sheave 10' of the first main rope 5 'is horizontal. For lifting the other car, the vertical position of the pulley 13 'for the car 13' with respect to the car 4 is adjusted and the part of the second main rope 6 'wrapped around the drive sheave 10' is horizontal. The vertical position of the pulley 12 'and the other winding pulley 14' with respect to the car 4 is adjusted (Fig. 6).
[0043] 次に、動作について説明する。かご 4を上昇させる場合には、図 5に示すように、一 方の駆動吊り下げ装置 17の駆動シーブ 10を反時計回り (A方向）に回転させるととも に、他方の駆動吊り下げ装置 21の駆動シーブ 10'を時計回り（即ち、駆動シーブ 10 の回転方向と逆方向、 A'方向）に回転させる。  Next, the operation will be described. When raising the car 4, as shown in FIG. 5, the drive sheave 10 of one drive suspension device 17 is rotated counterclockwise (direction A), and the other drive suspension device 21 is rotated. The drive sheave 10 ′ is rotated clockwise (ie, in the direction opposite to the rotation direction of the drive sheave 10 and in the A ′ direction).
[0044] 駆動シーブ 10の回転により、第 1及び第 2の主索 5, 6は、各かご吊り用プーリ 11, 12から駆動シーブ 10へそれぞれ移動され (即ち、 B方向へ移動され)、駆動シーブ 1 0から各巻き付け用プーリ 13, 14へそれぞれ移動される（即ち、 C方向へ移動される )。また、駆動シーブ 10'の回転により、第 1及び第 2の主索 5' , 6'は、各かご吊り用 プーリ 11 ' , 12'から駆動シーブ 10'へそれぞれ移動され (即ち、 B'方向へ移動され )、駆動シーブ 10'から各巻き付け用プーリ 13' , 14'へそれぞれ移動される (即ち、 C'方向へ移動される）。これにより、力ご 4が上昇する。  [0044] As the drive sheave 10 rotates, the first and second main ropes 5, 6 are moved from the car suspension pulleys 11, 12 to the drive sheave 10, respectively (that is, moved in the B direction), and driven. The sheave 10 is moved to each of the winding pulleys 13 and 14 (that is, moved in the C direction). Further, by the rotation of the drive sheave 10 ′, the first and second main ropes 5 ′ and 6 ′ are moved from the respective car suspension pulleys 11 ′ and 12 ′ to the drive sheave 10 ′ (that is, in the B ′ direction). And moved from the drive sheave 10 'to the winding pulleys 13' and 14 '(ie, moved in the C' direction). As a result, the force 4 increases.
[0045] かご 4を下降させる場合には、上記と反対方向へ駆動シーブ 10, 10'をそれぞれ 回転させる。これにより、上記と逆の動作を行い、かご 4が下降する。  [0045] When the car 4 is lowered, the drive sheaves 10, 10 'are rotated in the opposite direction to the above. As a result, the operation reverse to the above is performed, and the car 4 is lowered.
[0046] ここで、卷上機 8, 8'のそれぞれが発生する駆動トルク Tq'は、 2つの卷上機 8, 8， の駆動力によりかご 4が移動されるので、以下の式（2)により表される。 [0047] Tq' =Tq/2- -- (2) [0046] Here, the driving torque Tq 'generated by each of the lifting machines 8, 8' is that the car 4 is moved by the driving force of the two lifting machines 8, 8, and ). [0047] Tq '= Tq / 2--(2)
[0048] また、駆動シーブ 10, 10'が互いに逆方向へ回転するので、各卷上機 8, 8'の駆 動トルク Tq'が互いに打ち消し合う。これにより、かご 4の走行抵抗の低減ィ匕が図られ る。なお、かご 4の高さ方向についての卷上機 8, 8'間の間隔が大きくなるに従って、 かご 4に生じるねじれが大きくなるので、卷上機 8, 8'間の間隔を小さくするのが望ま しい。  [0048] Further, since the drive sheaves 10, 10 'rotate in opposite directions, the driving torques Tq' of the hoisting machines 8, 8 'cancel each other. As a result, the running resistance of the car 4 can be reduced. As the distance between the hoisting machines 8 and 8 'in the height direction of the car 4 increases, the twist generated in the car 4 increases, so the distance between the hoisting machines 8 and 8' should be reduced. Desirable.
[0049] このようなエレベータ装置では、一対の駆動吊り下げ装置 17, 21が昇降路 1内に 設けられ、一方の駆動吊り下げ装置 17の駆動シーブ 10の回転方向と、他方の駆動 吊り下げ装置 21の駆動シーブ 10 'の回転方向とが互いに逆方向になつているので、 各卷上機 8, 8'の駆動トルク Tq'を互いに打ち消し合わせることができる。これにより 、かご 4の走行抵抗の低減ィ匕を図ることができる。また、卷上機 8, 8'の駆動トルクが 半減するので、卷上機 8, 8'の小形化もさらに図ることができ、昇降路 1の省スペース 化をさらに図ることができる。  [0049] In such an elevator apparatus, a pair of drive suspension devices 17, 21 are provided in the hoistway 1, the rotational direction of the drive sheave 10 of one drive suspension device 17, and the other drive suspension device Since the rotational directions of the 21 drive sheaves 10 ′ are opposite to each other, the drive torques Tq ′ of the upper and lower machines 8, 8 ′ can cancel each other. As a result, the running resistance of the car 4 can be reduced. Further, since the driving torque of the hoisting machines 8, 8 'is halved, the hoisting machines 8, 8' can be further downsized, and the hoistway 1 can be further saved in space.
[0050] なお、上記の例では、卷上機 8がかご 4の下部に設けられ、卷上機 8'がかご 4の上 部に設けられている力 力ご 4の上部及び下部のいずれか一方に卷上機 8, 8'をまと めて設けてもよい。この場合、各かご吊り用プーリ 11, 12, 11 ' , 12'及び各巻き付け 用プーリ 13, 14, 13' , 14'も、かご 4の上部及び下部のいずれか一方にまとめて設 けられる。  [0050] In the above example, the lifting machine 8 is provided at the lower part of the car 4, and the lifting machine 8 'is provided at either the upper part or the lower part of the power car 4 provided at the upper part of the car 4. On the other hand, the elevators 8 and 8 'may be provided together. In this case, the car suspension pulleys 11, 12, 11 ′, 12 ′ and the wrapping pulleys 13, 14, 13 ′, 14 ′ are also installed together in either the upper part or the lower part of the car 4.
[0051] また、上記の例では、互いに独立した第 1及び第 2のおもり 15，， 16，により、第 1及 び第 2の主索 5' , 6'のそれぞれに張力が与えられるようになつている力 第 1及び第 2の主索 5' , 6'が接続された共通のおもり（張力手段）により、第 1及び第 2の主索 5' , 6'のそれぞれに張力を与えるようにしてもよい。また、昇降路 1内に設けた例えばば ね等の弾性体 (張力手段)で各主索 5' , 6'を引くことにより、第 1及び第 2の主索 5' , 6，のそれぞれに張力を与えるようにしてもよ!/、。  [0051] In the above example, the first and second main ropes 5 'and 6' are tensioned by the first and second weights 15 and 16, which are independent from each other. The connecting force The tension is applied to each of the first and second main ropes 5 'and 6' by a common weight (tensioning means) to which the first and second main ropes 5 'and 6' are connected. It may be. In addition, by pulling each main rope 5 ', 6' with an elastic body (tensioning means) such as a spring provided in the hoistway 1, each of the first and second main ropes 5 ', 6 is provided. You can give it a tension!
