Description
本発明は、ワイヤ，ロープ，ベルト，鎖状などの各種牽引部材を案内し、かつ当該牽引部材に固定された吊下げ部がそれぞれの間を通過していく、一対の片持ち滑車を備えた運搬用吊り滑車機構に関する。 The present invention includes a pair of cantilever pulleys that guide various traction members such as wires, ropes, belts, chains, and the like, and a suspension portion fixed to the traction member passes between them. The present invention relates to a suspension pulley mechanism for transportation.
この吊下げ部には、荷物，人間，動物などの各種運搬対象物が保持され、さらには図１３で示すように、運搬対象物そのものではなく、別途運搬用の第二の牽引部材が移動可能な形で取り付けられる。 This hanging part holds various objects to be transported such as luggage, human beings, animals and the like, and as shown in FIG. 13, a second pulling member for transportation is movable instead of the object to be transported itself. It can be installed in any shape.
本発明は、このように運搬用吊り滑車機構に案内される第一牽引部材に固定された吊下げ部に運搬対象物移動用の第二牽引部材を取り付けて、第一牽引部材を駆動することによりその吊下げ部位置、すなわち第二牽引部材による運搬対象物の受け地点（または送り地点）を任意に変更できるようにした、吊り滑車機構使用の運搬方法にも関する。 The present invention attaches the second traction member for moving the object to be transported to the suspension portion fixed to the first traction member guided by the transportation suspension pulley mechanism and drives the first traction member. This also relates to a transportation method using a suspension pulley mechanism, in which the position of the suspended portion, that is, the receiving point (or feeding point) of the object to be transported by the second pulling member can be arbitrarily changed.
本発明の運搬用吊り滑車機構は、各種環境において使用可能であり、例えば山，畑，牧場，工場，屋内遊戯施設，屋外遊戯施設，舞台装置，住宅，ビルなどにおいて用いることができる。 The suspension pulley mechanism of the present invention can be used in various environments, and can be used in, for example, mountains, fields, ranches, factories, indoor play facilities, outdoor play facilities, stage equipment, houses, buildings, and the like.
従来、ワイヤなどの牽引部材を案内し、かつ、当該牽引部材に固定された吊下げ部がそれぞれの間を通過していく一対の片持ち滑車を持つ、運搬用吊り滑車機構自体は知られている（下記特許文献１参照）。 2. Description of the Related Art Conventionally, a suspension pulley mechanism for transporting itself has a pair of cantilever pulleys that guide a pulling member such as a wire, and a suspension portion fixed to the pulling member passes between them. (See Patent Document 1 below).
ここで牽引部材と一体の吊下げ部が通過することになる一対の片持ち滑車は、吊下げ部通過空間域を構成する滑車対向面同士が略平行状態に設定されている。 Here, the pair of cantilever pulleys through which the suspending portion integral with the pulling member passes is set so that the pulley facing surfaces constituting the suspending portion passage space area are substantially parallel to each other.
このように従来の、牽引部材に固定した吊下げ部が一対の片持ち滑車対向面間を通過していく運搬用吊り滑車機構では、この対向面同士が略平行状態に設定されているため、牽引部材の曲折などに基づく外力を受けた運搬用吊り滑車機構が鉛直状態から傾くときなど、片持ち滑車の対向面に吊下げ部がいわば引っ掛かった状態になって牽引部材のスムーズな移動を担保できないという問題点があった。 In this way, in the suspension pulley mechanism for transportation in which the suspension portion fixed to the pulling member passes between the pair of cantilever facing surfaces, the facing surfaces are set in a substantially parallel state. When the suspension pulley mechanism for transportation that receives external force due to bending of the pulling member is tilted from the vertical state, the suspension part is in a state of being caught on the opposite surface of the cantilever pulley, ensuring smooth movement of the pulling member. There was a problem that it was not possible.
そこで、本発明では、牽引部材を案内する一対の片持ち滑車における吊下げ部通過用の滑車対向面同士が「上方から連続して下広がりとなる間隔態様で」設定されるようにし、これにより運搬用吊り滑車機構の傾きにともなう吊下げ部の片持ち滑車へのいわば引っ掛かりを防止して、牽引部材の移動の安定化を図ることを目的とする。 Therefore, in the present invention, the pulley facing surfaces for passing through the hanging portion in the pair of cantilever pulleys that guide the traction member are set so as to be “in an interval mode in which they continuously spread downward from above”, thereby An object of the present invention is to stabilize the movement of the traction member by preventing the suspending portion from being caught on the cantilever pulley due to the inclination of the carrying pulley mechanism.
また、一対の片持ち滑車が取り付けられる側板の上側対向部分同士の間隔を狭く設定し、これにより一対の側板上側部分それぞれへのワイヤ（支持部材）取付け作業などの簡単化を図ることを目的とする。 Moreover, it aims at simplification of the attachment operation | work etc. of the wire (support member) to each of a pair of side board upper part part by setting narrowly the space | interval of the upper side opposing parts of the side board to which a pair of cantilever pulleys are attached. To do.
また、例えば移動中の牽引部材が、それを案内する一対の片持ち滑車の間から下方にすり抜けたときに当該牽引部材を受けて保持し、かつ、吊下げ部が通過するときには当該吊下げ部との当接作用で開状態に移行する開閉部材を設け、これにより運搬用吊り滑車機構のいわばフェイルセーフ化を図ることを目的とする。 In addition, for example, when the moving traction member slips downward from between a pair of cantilever pulleys that guide it, the traction member is received and held, and when the suspending portion passes, the suspending portion An opening / closing member that shifts to an open state by the abutting action is provided, and the purpose of this is to make the carrying suspension pulley mechanism so-called fail-safe.
また、運搬用吊り滑車機構が鉛直状態から傾くこと以外にも、吊下げた軽重量の運搬対象物がその進行方向の左右横側に揺れる場合や、図１３のように吊下げ部に第二の牽引部材を移動可能な形で取り付けることで横方向の力が加わる場合などに、鉛直状態から横方向に傾いたままの吊下げ部が通過用の滑車対向面同士の間から大きく外れた回動状態で運搬用吊り滑車機構に進入することがある。 In addition to the tilting mechanism of the transporting pulley being tilted from the vertical state, the suspended light weight transporting object swings to the left and right side in the traveling direction, When a lateral force is applied by attaching the traction member in a movable form, the suspension part that is tilted laterally from the vertical state is greatly disengaged from between the pulley facing surfaces for passing. It may enter the suspension pulley mechanism for transportation.
この進入状況では、吊り下げ部の運搬用吊り滑車機構へのいわば「入り」がむずかしい。なお、ここでの横方向への傾き（回動）は、運搬用吊り滑車機構と吊下げ部との間の相対的なものである。 In this approach situation, it is difficult to “enter” the suspension pulley mechanism for transportation of the suspension part. In addition, the inclination (rotation) to the horizontal direction here is a relative thing between the suspension pulley mechanism for conveyance and a suspension part.
そこで、運搬用吊り滑車機構に対するこの横方向への傾き（回動）ずれが生じた場合の吊下げ部を一対の片持ち滑車の間に相対的に誘導する案内部を設け、吊り下げ部の、運搬用吊り滑車機構への進入動作の確実化を図ることを目的とする。 Therefore, a guide portion is provided for relatively guiding the suspension portion between the pair of cantilever pulleys when the lateral tilt (rotation) deviation occurs with respect to the transportation suspension pulley mechanism. An object of the present invention is to ensure the operation of entering the suspension pulley mechanism for transportation.
さらには、一対の片持ち滑車を備えた吊り滑車機構に案内される第一牽引部材に固定された吊下げ部に運搬対象物移動用の第二牽引部材を取り付けた状態で、第一牽引部材を駆動してその吊下げ部位置、すなわち第二牽引部材による運搬対象物の受け地点（または送り地点）を任意に変更できるようにし、これにより一対の片持ち滑車を備えた吊り滑車機構の用途の豊富化を図ることを目的とする。 Further, the first traction member is attached with the second traction member for moving the object to be transported attached to the suspending portion fixed to the first traction member guided by the suspension pulley mechanism having a pair of cantilever pulleys. The suspension part position, that is, the receiving point (or feeding point) of the object to be transported by the second pulling member can be arbitrarily changed, and thereby the use of the suspension pulley mechanism provided with a pair of cantilever pulleys The purpose is to enrich.

図示の実施形態における運搬用吊り滑車機構の基本的特徴は、
(21)片持ち滑車１ｂそれぞれの円形状対向面１ｃが「ハの字状」の下広がり対向状態で設定され、
(22)片持ち滑車１ｂそれぞれが取り付けられる一対の平側板１ａも「ハの字状」の下広がり対向状態で設定されている、すなわち当該平側板同士の頂部分が狭い、
ことである。
The basic characteristics of the suspension pulley mechanism for transportation in the illustrated embodiment are as follows:
(21) The circular facing surface 1c of each of the cantilever pulleys 1b is set in a state of facing the bottom of the “C” shape,
(22) A pair of flat side plates 1a to which each of the cantilever pulleys 1b is attached is also set in a state of facing downwards in a “C” shape, that is, the top portions of the flat side plates are narrow.
That is.
上記(21)の基本的特徴により、
例えば牽引ワイヤ２の進行方向がそれまでの直進状態から変化して、運搬用吊り滑車機構１，１’がその鉛直状態から傾くような場合にも、鉛直状態を維持したままの吊下げ部３の平板状部３ａが当該運搬用吊り滑車機構の円形状対向面１ｃに引っ掛かるようなことは生じにくい。
Due to the basic characteristics of (21) above,
For example, even when the traveling direction of the pulling wire 2 is changed from the straight traveling state so far and the suspension pulley mechanism 1 or 1 'for transportation is inclined from the vertical state, the hanging portion 3 that maintains the vertical state. It is difficult for the flat plate-like portion 3a to be caught on the circular opposed surface 1c of the carrying suspension pulley mechanism.
上記(22)の基本的特徴により、
運搬用吊り滑車機構１，１’が、上端側直近の計二個の孔部１ｆで支持ワイヤ６に取り付けられることになってその取付け作業の簡単化を図れ、また、牽引ワイヤ２を折返し態様にした場合の上ワイヤ部分２ｂおよびそれを案内する滑車１ｇの配設スペースの効率化を図れる。
Due to the basic characteristics of (22) above,
The suspension pulley mechanism 1, 1 'for transportation is attached to the support wire 6 through a total of two holes 1f closest to the upper end side, so that the attachment work can be simplified, and the pulling wire 2 is folded back. In this case, the space for arranging the upper wire portion 2b and the pulley 1g for guiding the upper wire portion 2b can be improved.
図１および図２は、牽引ワイヤ２の下ワイヤ部分２ａに固定した吊下げ部３が、一対の片持ち滑車１ｂのテーパ状周回面１ｄのそれぞれに案内される状態を示している。 1 and 2 show a state in which the suspension portion 3 fixed to the lower wire portion 2a of the pulling wire 2 is guided to each of the tapered circumferential surfaces 1d of the pair of cantilever pulleys 1b.
図１は下ワイヤ部分２ａの進行方向側から見たときのいわば正面図に相当し、図２は図１に対応した側面図に相当する。 1 corresponds to a front view when viewed from the traveling direction side of the lower wire portion 2a, and FIG. 2 corresponds to a side view corresponding to FIG.
図１および図２において、
(31)一対の平側板１ａそれぞれの孔部１ｆを通した支持ワイヤ６が、立ち木，支柱，電柱，建造物の一部（ベランダ，柱など）や、ベランダなどに固定した金具４１，４２（図１５，図１６参照）に取り付けられ、

1 and 2,
(31) The support wire 6 that passes through the hole 1f of each of the pair of flat side plates 1a is a standing tree, a support column, a utility pole, a part of a building (a veranda, a column, etc.), or a metal fitting 41, 42 ( 15 and 16)),
(32) The lower wire portion 2a of the pulling wire 2 and the hanging portion 3 fixed to the pulling wire 2 are guided in contact with the tapered circumferential surface 1d of the pair of cantilever pulleys 1b.
(33) Guided with the upper wire portion 2b of the pulling wire 2 in contact with the pulley 1g,
(34) The hook 4a of the suspended receiving portion 4 is hung on the hole 3b of the hanging portion 3 that moves in the same direction as the lower wire portion 2a.
(35) A washer 1e is provided between each of the pair of cantilever pulleys 1b and the base 1a 'of the flat side plate 1a.
一対の片持ち滑車１ｂそれぞれの円形状対向面１ｃの間隔は、ワッシャー１ｅの厚みを変えることにより、牽引ワイヤ２の太さに応じて自由に調整できる。 The distance between the circular facing surfaces 1c of each of the pair of cantilever pulleys 1b can be freely adjusted according to the thickness of the pulling wire 2 by changing the thickness of the washer 1e.
また、片持ち滑車１ｂは、牽引ワイヤ２から外向きの力を受けるのでその軸を強く固定しなくても、外れることがない。片持ち滑車１ｂの軸を強く固定しないことによりその交換作業も容易になる。 Further, since the cantilever pulley 1b receives an outward force from the pulling wire 2, the cantilever pulley 1b does not come off even if its shaft is not firmly fixed. By not strongly fixing the shaft of the cantilever pulley 1b, the replacement work is facilitated.
図３は、一対の平側板１ａそれぞれの牽引ワイヤ移動方向の前後位置に片持ち滑車１ｂを設けた、計二組の当該片持ち滑車からなる運搬用吊り滑車機構１’を示している。 FIG. 3 shows a transportation suspension pulley mechanism 1 ′ composed of a total of two sets of cantilever pulleys provided with cantilever pulleys 1 b at the front and rear positions of the pair of flat side plates 1 a in the pulling wire movement direction.
図４は、荷物５を保持した吊下げ部３が、図３の二組の片持ち滑車１ｂを備えた運搬用吊り滑車機構１に接近したときの牽引ワイヤ２の屈曲状態を示している。 FIG. 4 shows a bent state of the pulling wire 2 when the hanging portion 3 holding the load 5 approaches the carrying suspension pulley mechanism 1 including the two sets of cantilever pulleys 1b shown in FIG.
図５は、荷物５を保持した吊下げ部３が、図１，図２の一組の片持ち滑車１ｂを備えた運搬用吊り滑車機構１に接近したときの牽引ワイヤ２の屈曲状態を示している。 FIG. 5 shows a bent state of the pulling wire 2 when the hanging portion 3 holding the load 5 approaches the carrying suspension pulley mechanism 1 having the pair of cantilever pulleys 1b of FIGS. ing.
図４および図５からも分かるように、二組の片持ち滑車１ｂを備えた図３の運搬用吊り滑車機構１’における牽引ワイヤ２の屈曲状態は、一組の片持ち滑車１ｂを備えた図２の運搬用吊り滑車機構１のそれに比べて、緩やかになっている。このため、二組の片持ち滑車１ｂを備えた運搬用吊り滑車機構１’の方が、一組の片持ち滑車１ｂを備えた運搬用吊り滑車機構１よりも吊下げ部３をスムーズに通過する。 As can be seen from FIGS. 4 and 5, the bent state of the pulling wire 2 in the transport suspension pulley mechanism 1 ′ of FIG. 3 having two sets of cantilever pulleys 1b includes a pair of cantilever pulleys 1b. Compared to that of the carrying suspension pulley mechanism 1 of FIG. For this reason, the suspension suspension pulley mechanism 1 ′ having two sets of cantilever pulleys 1b passes through the suspension portion 3 more smoothly than the suspension suspension pulley mechanism 1 having a pair of cantilever pulleys 1b. To do.
図６は、運搬用吊り滑車機構１，１’のところで、牽引ワイヤ２の配設状態がその進行直線方向から１０度ほど右側に変化する場合を示している。 FIG. 6 shows a case where the arrangement state of the traction wire 2 changes to the right side by about 10 degrees from the traveling linear direction at the transportation suspension pulley mechanism 1, 1 ′.
このとき、牽引ワイヤ２から右方向への力を受ける運搬用吊り滑車機構１，１’はその下端部分が右側に移動する。 At this time, the lower ends of the transport suspension pulley mechanisms 1 and 1 ′ that receive a rightward force from the pulling wire 2 move to the right.
そして、この運搬用吊り滑車機構１，１’の右側（図示反時計方向）への回動にともない、一対の片持ち滑車１ｂも図６の右方向へ回動する。 As the carrying suspension pulley mechanism 1, 1 'turns to the right (counterclockwise in the figure), the pair of cantilever pulleys 1b also turn to the right in FIG.
上述したように、この一対の片持ち滑車１ｂの円形状対向面１ｃは「ハの字状」の下広がり対向状態で設定されている。 As described above, the circular facing surfaces 1c of the pair of cantilever pulleys 1b are set in a state of facing downwardly in a “C” shape.
そのため、図６で示すように一対の片持ち滑車１ｂが右方向に回動しても、荷物５を吊るした吊下げ部３の平板状部３ａが当該片持ち滑車の円形状対向面１ｃに引っ掛かることは生じにくい。 Therefore, as shown in FIG. 6, even if the pair of cantilever pulleys 1 b rotate to the right, the flat plate-like portion 3 a of the hanging portion 3 that suspends the load 5 remains on the circular opposing surface 1 c of the cantilever pulley. It is hard to get caught.
図７および図８は、一対の片持ち滑車１ｂの隙間部分から牽引ワイヤ２が万が一にすり抜けてしまったときの牽引ワイヤ保持機能を示している。図７は正面図を示し、図８は側面図を示す。 FIG. 7 and FIG. 8 show the pulling wire holding function when the pulling wire 2 slips through the gap between the pair of cantilever pulleys 1b. FIG. 7 shows a front view and FIG. 8 shows a side view.
すなわち、仮に牽引ワイヤ２が片持ち滑車１ｂの隙間部分から下方にすり抜けたとしても、当該牽引ワイヤは、当該片持ち滑車の横側（進行方向前後側）に設けた一対の蝶番１ｋ（蝶番可動部１ｎ）にいわば引っかかって保持される。 That is, even if the pulling wire 2 slips downward from the gap portion of the cantilever pulley 1b, the pulling wire is connected to a pair of hinges 1k (movable hinges) provided on the side of the cantilever pulley. Part 1n) is caught and held.
そのため、運搬用吊り滑車機構１，１’の一対の片持ち滑車１ｂの隙間部分から牽引ワイヤ２が離脱して落下するようなことは生じない。 Therefore, it does not occur that the pulling wire 2 is detached and dropped from the gap portion between the pair of cantilever pulleys 1b of the carrying suspension pulley mechanism 1, 1 '.
一対の蝶番基部１ｍは、図８で示すように、それぞれ運搬用吊り滑車機構１’の平側板１ａの片持ち滑車間にボルト，ナットで固定され、蝶番可動部１ｎはその下面部分が台座１ｑに当接した状態に保持されている。 As shown in FIG. 8, the pair of hinge base parts 1m are fixed with bolts and nuts between the cantilever pulleys of the flat side plate 1a of the carrying suspension pulley mechanism 1 ', and the lower surface part of the hinge movable part 1n is a base 1q. Are held in contact with the
一対の台座１ｑは、蝶番可動部１ｎの下方への開き過ぎを阻止するため一対の平側板１ａにボルト，ナットで固定されている。 The pair of bases 1q are fixed to the pair of flat side plates 1a with bolts and nuts in order to prevent the hinge movable part 1n from opening too much downward.
なお、通常の、吊下げ部３が片持ち滑車１ｂの間を通過するときは、その平板状部３ａの先端部分で蝶番可動部１ｎが上方に持上げられる。吊下げ部３が片持ち滑車１ｂの間を通過し終えると、蝶番可動部１ｎは、その自重で図７の初期位置に復帰する。 In addition, when the normal suspension part 3 passes between the cantilever pulleys 1b, the hinge movable part 1n is lifted upward by the tip part of the flat plate-like part 3a. When the hanging part 3 finishes passing between the cantilever pulleys 1b, the hinge movable part 1n returns to the initial position in FIG. 7 by its own weight.
図８で明示されるように、蝶番可動部１ｎはその前後方向（図２，図３，図８の左右方向）の端側部分が円弧形状に設定されている。 As clearly shown in FIG. 8, the hinge movable portion 1n has an arc-shaped end portion in the front-rear direction (left-right direction in FIGS. 2, 3, and 8).
牽引ワイヤ２が移動するとき、この蝶番可動部１ｎの円弧形状部分１ｐに吊下げ部３の平板状部３ａの側端面（前端面）があたるので、当該蝶番可動部の上方への移動がスムーズにおこなわれる。 When the pulling wire 2 moves, the arc-shaped part 1p of the hinge movable part 1n hits the side end face (front end face) of the flat plate-like part 3a of the hanging part 3, so that the hinge movable part moves smoothly upward. To be done.
図９および図１０は、吊下げ部３の平板状部３ａを確実に円形状対向面１ｃ同士の間に進入させるための案内機構を示している。図９は底面視を示し、図１０は、吊下げ部３の平板状部３ａが運搬用吊り滑車機構１’に進入するときに、入口拡大用案内板１ｒと当該平板状部との当接作用でこの案内板側の運搬用吊り滑車機構１’が図示時計方向に回動する場合を示している。 9 and 10 show a guide mechanism for surely allowing the flat plate-like portion 3a of the hanging portion 3 to enter between the circular opposing surfaces 1c. FIG. 9 shows a bottom view, and FIG. 10 shows the contact between the entrance enlargement guide plate 1r and the flat plate portion when the flat plate portion 3a of the hanging portion 3 enters the carrying suspension pulley mechanism 1 ′. This shows a case where the suspension pulley mechanism 1 'on the guide plate side rotates in the clockwise direction in the figure.
図９の吊下げ部３が運搬用吊り滑車機構１’に進入するとき、端曲面１ｓが平板状部３ａを案内して円形状対向面１ｃの間に誘導する。このとき運搬用吊り滑車機構１’が下ワイヤ部分２ａを軸として回動することになる。 When the suspending portion 3 of FIG. 9 enters the carrying suspension pulley mechanism 1 ', the end curved surface 1s guides the flat plate portion 3a and guides it between the circular opposing surfaces 1c. At this time, the carrying suspension pulley mechanism 1 'rotates around the lower wire portion 2a.
図１０はこの運搬用吊り滑車機構１’の回動状態を示している。
すなわち、運搬用吊り滑車機構１’が二点鎖線の位置から図示左方向（図示時計方向）に回動している。なお、荷物５が軽く、牽引ワイヤ２の張力が強い場合には、運搬用吊り滑車機構１’が動かずに、平板状部３ａが図示右方向（図示反時計方向）に回動することになる。
FIG. 10 shows the rotation state of the carrying suspension pulley mechanism 1 ′.
That is, the transportation suspension pulley mechanism 1 'is rotated in the left direction (clockwise direction in the figure) from the position of the two-dot chain line. When the load 5 is light and the tension of the pulling wire 2 is strong, the plate-like portion 3a rotates in the right direction in the figure (counterclockwise in the figure) without moving the suspension pulley mechanism 1 'for transportation. Become.
また、運搬用吊り滑車機構１’を用いた場合において、同一の平側板１ａに取付けられた片持ち滑車１ｂ同士の間に、通過中の平板状部３ａが下ワイヤ部分２ａを軸として回動して嵌まり込むことを対向平面１ｔが阻止するので、平板状部３ａのスムーズな通過移動が担保される。 Further, in the case of using the carrying suspension pulley mechanism 1 ′, the passing flat plate portion 3a rotates around the lower wire portion 2a between the cantilever pulleys 1b attached to the same flat side plate 1a. Since the opposing flat surface 1t prevents the fitting, the smooth passage movement of the flat plate portion 3a is ensured.
図１１は、運搬用吊り滑車機構１，１’の基本的な使用概念を示している。
ここでは単なる説明の便宜上、建造物の天井７および壁８を、運搬用吊り滑車機構や牽引ワイヤの取付け対象としている。
FIG. 11 shows the basic concept of use of the suspension pulley mechanism 1, 1 ′ for transportation.
Here, for convenience of explanation, the ceiling 7 and the wall 8 of the building are the attachment targets of the suspension pulley mechanism for transportation and the pulling wire.
ここで、二個の運搬用吊り滑車機構１’がその孔部１ｆに通した支持ワイヤ６で天井７に懸架され、また、当該運搬用吊り滑車機構に案内される折返しループ状の牽引ワイヤ２が、一方の壁８に取り付けた滑車１０と他方の壁８に取り付けたワイヤ駆動部９の滑車１１との間に配設されている。 Here, two suspending pulley mechanisms 1 'for transportation are suspended on the ceiling 7 by a support wire 6 passed through the hole 1f, and the pulling loop-shaped pulling wire 2 is guided by the transportation suspension pulley mechanism. Is arranged between a pulley 10 attached to one wall 8 and a pulley 11 of a wire drive unit 9 attached to the other wall 8.
壁８に取り付けたワイヤ駆動部９および滑車１０，１１の作用で牽引ワイヤ２が図示左右方向に選択的に移動することにより、当該牽引ワイヤに固定した吊下げ部３の荷物５が左右の壁８の間で運搬される。 The pulling wire 2 is selectively moved in the horizontal direction in the figure by the action of the wire drive unit 9 and the pulleys 10 and 11 attached to the wall 8, so that the luggage 5 of the hanging unit 3 fixed to the pulling wire is moved to the left and right walls. Carried between 8.

図１２は、立ち木２２の高地側で右ワイヤ部分２ｃの吊下げ部３’に保持された伐採木材を、ウインチ３０，３１の駆動操作により、当該ウインチが設置された低地側に運搬している状態である。 In FIG. 12, the felled timber held by the hanging portion 3 ′ of the right wire portion 2 c on the high ground side of the standing tree 22 is conveyed to the low ground side where the winch is installed by driving the winches 30 and 31. State.
このときの左ワイヤ部分２ｄの吊下げ部３’はいわば空身状態になっているが、このような空身ではなく、ウインチ側から高地側の滑車１２への運搬物を当該吊下げ部に取り付けるといった使い方も勿論ありえる。 At this time, the suspending portion 3 ′ of the left wire portion 2d is in an empty state, but it is not such an empty portion, and a transported object from the winch side to the pulley 12 on the high ground side is attached to the suspending portion. Of course it can be used.
