Description
本発明は、超高層建物において、揚重能力の小さな廉価な汎用揚重機を使用して、エレベーター巻上機のような重量物を高高位置まで揚重する揚重方法に関する。 The present invention relates to a lifting method for lifting a heavy object such as an elevator hoist to a high position using an inexpensive general-purpose lifting machine having a small lifting capacity in a high-rise building.
近年建築物の超高層化に伴いエレベーターの超高速化・大型化が進んでおり、これに比例してエレベーターを駆動する巻上機も超大型化・超重量化してきている傾向がある。特に、国外では１００階建て以上の建物が数多く建設計画されこの傾向が顕著である。 In recent years, with the increase in the number of buildings, elevators have become faster and larger, and in proportion to this, hoisting machines that drive elevators tend to be larger and heavier. In particular, there are many plans to build more than 100 stories outside of Japan, and this tendency is remarkable.
このような超高層建築物に設置するエレベーターの巻上機は最上階の機械室に設置する必要があるため、超重量物の巻上機を如何にして最上階機械室まで揚重するかが大きな課題となっている。 Since the elevator hoist installed in such a high-rise building needs to be installed in the machine room on the top floor, how to lift the super heavy object hoist to the machine room on the top floor It has become a big issue.
もっとも、揚重能力の大きい建築用タワークレーンを使用することが可能であれば、このタワークレーンで、巻上機を揚重できるが、特に国外ではタワークレーンの能力が低い場合や、タワークレーン設置時期に工期が合致せずにタワークレーンを使用した巻上機の揚重ができない場合が多い。 However, if it is possible to use a tower crane for construction with a large lifting capacity, this tower crane can lift the hoisting machine, but especially when the capacity of the tower crane is low or a tower crane is installed overseas. In many cases, the hoisting machine using a tower crane cannot be lifted because the construction period does not match.
さらに国内でも、既設ビルの超高層エレベーターの入れ替え工事などでは、タワークレーンが設置できないため、タワークレーンによる揚重は不可能であった。 Furthermore, in Japan, tower cranes cannot be installed when replacing high-rise elevators in existing buildings, so it was impossible to lift the tower crane.
ここで、一般的なエレベーターの巻上機の揚重方法に関する従来技術としては、例えば特許文献１によれば、ウィンチからのウィンチロープを滑車を介して巻き回し、このウィンチロープを巻上機に装着した玉掛けワイヤに係合させ、ウィンチを駆動させることで、昇降路頂部の機械室へ向けて巻上機を揚重する方法が提案されている。 Here, as a conventional technique related to a lifting method of a general elevator hoisting machine, for example, according to Patent Document 1, a winch rope from a winch is wound through a pulley and the winch rope is used as a hoisting machine. There has been proposed a method of lifting a hoisting machine toward a machine room at the top of a hoistway by engaging a mounted sling wire and driving a winch.
また、重量物を揚重する従来技術として、例えば特許文献２によれば、揚重能力を増加させるため、一定位置に吊持される定滑車と、揚重すべき重量物と同期して昇降する動滑車とを設けて、２対１ローピングとして揚重する方法が従来から提案されている。 Further, as a conventional technique for lifting a heavy object, for example, according to Patent Document 2, in order to increase the lifting capacity, a fixed pulley suspended at a fixed position and a lifting / lowering synchronized with the heavy object to be lifted are performed. There has been proposed a method of providing a moving pulley that lifts up as 2 to 1 roping.
一般に市販されている汎用揚重機（ウィンチ）は、牽引ロープを巻き取る巻き取りドラムの大きさに限界があり、巻き取りドラムの径を大きくすれば巻き取れるロープの長さ（揚程）は大きくなるが、牽引力は減少する。この揚程と牽引力の双方を満たすためには、ウィンチ本体も大型になり重量も増してしまう。 Generally, general-purpose lifting machines (winches) that are commercially available have a limit in the size of the take-up drum that winds up the tow rope, and if the diameter of the take-up drum is increased, the length (lift) of the rope that can be taken up becomes larger. However, the traction force decreases. In order to satisfy both the lifting height and the traction force, the winch body is also increased in size and weight.
一般市販されている汎用ウィンチの能力は牽引力２〜５ｔｏｎ、ロープの巻き取り量（揚程）は２００ｍが限度である。この能力では、１：１ローピングで５ｔｏｎのエレベーター巻上機を揚程２００ｍ、又は２：１ローピングで１０ｔｏｎの巻上機を揚程１００ｍ（２５〜３０階程度の建物高さ）までしか揚重することができない。 General commercially available winches have a traction of 2 to 5 tons and a rope winding amount (lift) of 200 m. With this capability, a 5 ton elevator hoist can be lifted up to a height of 200 m by 1: 1 roping, or a 10 ton hoist can be lifted up to a height of 100 m (building height of about 25-30 floors) by 2: 1 roping. I can't.
従って、上記の汎用ウィンチを使用した場合、上記の特許文献ｌの揚重方法では、１０〜２０階建ての中・高層用エレベーターの巻上機を揚重可能であるが、５０〜１００階建て又はそれ以上の超高層用エレベータでは、ウィンチ能力（揚程と牽引力）が不足し、適用することができない。 Therefore, when the above-mentioned general purpose winch is used, the lifting method of the above-mentioned Patent Document 1 can lift 10 to 20-story middle / high-rise elevator hoisting machines. Or, an elevator for a super high-rise building having a higher height is not capable of being applied due to insufficient winch capacity (lift and traction).
さらに、上記の特許文献２に開示された２対１ローピングとする揚重方法でも、汎用ウインチでは揚重高さ（揚程）に対応できないという不都合が生じていた。 Furthermore, even the lifting method of 2 to 1 roping disclosed in Patent Document 2 described above has a disadvantage that the general-purpose winch cannot cope with the lifting height (lifting height).
本発明の目的は、上記不都合を鑑みてなされたものであり、５０〜１００階建て或いはそれ以上の超高層エレベーターにおいて、重量物であるエレベーター巻上機を、比較的能力の小さい汎用揚重機を使用して高高所の建物頂部の機械室へ揚重可能とする揚重方法を提供することにある。 The object of the present invention has been made in view of the above disadvantages. In a super high-rise elevator of 50 to 100 stories or more, an elevator hoisting machine which is a heavy object is replaced with a general-purpose lifting machine having a relatively small capacity. It is intended to provide a lifting method that can be used to lift into a machine room at the top of a high altitude building.
本発明は上記目的を達成するため、超高層用エレベーターに使用されるエレベーター巻上機をかご昇降路の最上階機械室に揚重する揚重方法において、超高層用建物の最上階乗場に揚重ウィンチを設置する工程と、前記揚重ウィンチから引き出され又は巻き取られる減速ロープを、前記かご昇降路内の側面に設置された方向転換金車を介して、揚重梁に吊り下げられた定滑車と前記エレベーター巻上機と連動して昇降する動滑車との間で巻き回して減速ローピングを形成する工程と、前記動滑車と揚重すべき前記エレベーター巻上機とを長さ方向に分割可能な懸垂ロープで連結する工程と、前記揚重ウィンチを駆動させて前記動滑車と前記懸垂ロープによって前記エレベーター巻上機をエレベーターホール１階から中間階まで揚重する工程と、前記中間階に支持機構部を設けて当該支持機構部上に前記エレベーター巻上機を仮置きする工程と、前記仮置きの状態で前記分割可能な懸垂ロープの内で下側の第１の懸垂ロープを取り外して前記第１の懸垂ロープよりも上側の第２の懸垂ロープを前記エレベーター巻上機に連結する工程と、再度前記揚重ウィンチを駆動させて前記エレベーター巻上機を前記機械室まで揚重する工程と、を備えたことを特徴とする。 In order to achieve the above object, the present invention provides a lifting method for lifting an elevator hoisting machine used for a super high rise elevator to the top floor machine room of a car hoistway. A step of installing a heavy winch, and a deceleration rope drawn out or wound up from the lifting winch was suspended by a lifting beam via a turn-turning gold wheel installed on a side surface in the car hoistway forming a wrapping by reduction roping between the movable pulley of the lift in conjunction with the fixed pulley and the elevator hoisting machine, and the elevator hoist the be movable pulley and Agekasane lengthwise a step of connecting at dividable suspension rope, the steps of the Agekasane the lifting winch and by driving the elevator hoisting machine by the movable pulley and the suspension rope from the elevator hall 1 floor to the intermediate floor The elevator and step of temporarily placing the hoisting machine, among the first suspension under side of the divisible suspension rope in a state of the temporary placement to the intermediate floor in providing the support mechanism the support mechanism on Removing the rope and connecting the second suspension rope above the first suspension rope to the elevator hoisting machine, and again driving the lifting winch to bring the elevator hoisting machine to the machine room characterized by comprising the steps of Agekasane, the.
本発明によれば、高価な大型揚重機（ウィンチ）を使用せず、また建物の特別な補強も要せず、廉価で比較的小能力の汎用揚重機によって、超高層建築物の高所まで重量物を揚重することができる。 According to the present invention, an expensive large-scale lifting machine (winch) is not used, and no special reinforcement of a building is required. Heavy objects can be lifted.
さらに、懸垂ロープの揚重段数を増やせば５００ｍ又は８００ｍの超超高層建物でも特殊揚重機を使用することなく、また建物の補強をすることなく、超重量物であるエレベーター巻上機を高高所の機械室まで揚重することが可能となる。 Furthermore, if the number of lifting stages of the suspension rope is increased, the elevator hoisting machine, which is a super heavy object, can be raised without using a special lifting machine or reinforcing the building even in a super high-rise building of 500 m or 800 m. It is possible to lift up to the machine room.

Here, the general purpose lifting winch 13 is installed in advance at the landing on the top floor 4. Further, the towing rope 18 and the deceleration rope 19 drawn from the lifting winch 13 are wound between the fixed pulley 16 and the moving pulley 17 to form a deceleration roping.
図１は本実施形態に係る巻上機揚重方法の概念構成を示すものであり、巻上機揚重方法の主たる基本的構成は、揚重梁１０（図２を参照）に吊り下げられた定滑車１６と、エレベーター巻上機２３と連動して昇降する動滑車１７と、定滑車１６と動滑車１７とに巻き回された牽引ロープ１８及び減速ロープ１９と、牽引ロープ１８及び減速ロープ１９を牽引する揚重用巻上機（揚重ウィンチ）１３と、動滑車１７に吊り下げられたエレベーター巻上機２３と、を備えている。 FIG. 1 shows a conceptual configuration of a hoisting machine lifting method according to the present embodiment, and the main basic configuration of the hoisting machine lifting method is suspended from a lifting beam 10 (see FIG. 2). The fixed pulley 16, the moving pulley 17 that moves up and down in conjunction with the elevator hoisting machine 23, the traction rope 18 and the reduction rope 19 wound around the fixed pulley 16 and the movement pulley 17, the traction rope 18 and the reduction rope A hoisting machine for lifting 19 (lifting winch) 13 and an elevator hoisting machine 23 suspended from a movable pulley 17 are provided.
本実施形態では、汎用の揚重ウィンチ１３を用いて、重量物であるエレベーター巻上機２３を長大な揚程５の高高位置まで揚重する超高層用エレベーターの巻上機揚重方法を提供するものであって、動滑車１７とエレベーター巻上機２３とを連結する懸垂ロープ２０，２１（図２を参照）を分割可能にすることを主たる特徴とするものである。本発明の上記特徴に関する揚重方法について、経時的に順を追って以下説明する。 In the present embodiment, there is provided an elevator hoisting method for an elevator for a super high rise that uses a general-purpose lifting winch 13 to lift an elevator hoisting machine 23, which is a heavy object, to a high position of a long lift 5. The main feature is that the suspension ropes 20 and 21 (see FIG. 2) for connecting the movable pulley 17 and the elevator hoisting machine 23 can be divided. The lifting method related to the above features of the present invention will be described below in order.
図２に示すエレベータシャフト（塔内）７の全体断面図において、本実施形態は、重量物である揚重貨物（エレベーター巻上機）２３を、最上階エレベーターホール４に設置した汎用の揚重用巻上機（揚重ウィンチ）１３を用いて、エレベーターホール１階１からエレベーター塔内７を経由して建物頂部にあるエレベーター機械室９まで揚重するものである。 In the overall cross-sectional view of the elevator shaft (inside the tower) 7 shown in FIG. 2, the present embodiment is for general-purpose lifting where a heavy cargo (elevator hoisting machine) 23 is installed in the uppermost elevator hall 4. A hoisting machine (lifting winch) 13 is used to lift the elevator hall from the first floor 1 to the elevator machine room 9 at the top of the building via the elevator tower 7.
揚重に際して、例えば１ローピングで牽引力が５ｔｏｎ、ロープ巻き取り量が２００ｍの汎用の揚重ウィンチ１３を用いて、１５ｔｏｎ未満の貨物を２００ｍの高高所の機械室９に揚重しようとする場合に、ウィンチ１３の牽引力が不足するため、図２に示すローピング１９を滑車を使って３：１に減速（揚重力は増大）しなければ必要揚重力（１５ｔｏｎ）が得られない。しかし、ローピング１９を３：１に減速すると揚程が１／３（６７ｍ）に減少してしまい、２００ｍの高さまで揚重出来ない。 When lifting, for example, using a general-purpose lifting winch 13 with a pulling force of 5 tons and a rope take-up amount of 200 tons, a cargo of less than 15 tons is to be lifted into a machine room 9 at a high altitude of 200 meters. In addition, since the traction force of the winch 13 is insufficient, the necessary lifting gravity (15 ton) cannot be obtained unless the roping 19 shown in FIG. 2 is decelerated to 3: 1 (lifting gravity increases) using a pulley. However, if the roping 19 is decelerated to 3: 1, the lift is reduced to 1/3 (67 m), and the lift cannot be made to a height of 200 m.
そこで、本実施形態では、揚重の高さを補うために、図２の動滑車１７に対して、長さが揚重ウィンチ１３の巻き取り量２００ｍの１／３（６７ｍ）の懸垂ロープ２０，２１を２本直列接続し、これらの懸垂ロープ２０，２１の下端を貨物（エレベーター巻上機２３）に接続している。 Therefore, in the present embodiment, to compensate for the height of lifting, the suspended rope 20 having a length 1/3 (67 m) of the winding amount of the lifting winch 13 of 200 m with respect to the moving pulley 17 of FIG. , 21 are connected in series, and the lower ends of these suspension ropes 20, 21 are connected to the cargo (elevator hoisting machine 23).
このとき、懸垂ロープ２０，２１は、４０φの太い（破断係数９７ｔｏｎ、安全係数６）を使用しても良いが、１本の重量が非常に重くなり、取り扱いが非常に困難になるので同じ破断力になるような２０φ程度の中太のものを複数本並列にして垂下すると作業が容易になる。 At this time, the suspension ropes 20 and 21 may be 40φ thick (breaking factor 97 ton, safety factor 6), but one piece becomes very heavy and handling becomes very difficult. Work is facilitated by hanging a plurality of medium-thick ones with a diameter of about 20φ in parallel.
次に、本発明の実施形態に係る巻上機揚重方法によって、エレベーター巻上機２３をエレベーターホール中間階１である下層階２まで揚重する工程について、図３〜図５を参照しながら以下説明する。図３は本実施形態に係る巻上機揚重方法に関する揚程の１／３揚重時の下層階２における重量貨物とその仮置き構台との関連構成を示す図であり、図４は本実施形態に係る巻上機揚重方法に関する揚程の１／３揚重時の下層階２における重量貨物の仮置き構台の設置構成を示す図であり、図５は本実施形態に係る巻上機揚重方法に関する揚程の２／３揚重時の開始における懸垂ロープ２１の掛け方の構成を示す図である。 Next, the process of lifting the elevator hoisting machine 23 to the lower floor 2 which is the elevator hall intermediate floor 1 by the hoisting machine lifting method according to the embodiment of the present invention will be described with reference to FIGS. This will be described below. FIG. 3 is a diagram showing a related configuration of the heavy cargo on the lower floor 2 at the time of 1/3 lifting of the lifting distance related to the hoisting machine lifting method according to the present embodiment and its temporary gantry, and FIG. It is a figure which shows the installation structure of the temporary placing stand of the heavy cargo in the lower floor 2 at the time of 1/3 lifting of the lift regarding the lifting machine lifting method which concerns on a form, FIG. 5: FIG. 5 shows the lifting machine lifting which concerns on this embodiment It is a figure which shows the structure of how to hang suspension rope 21 in the start at the time of 2/3 lifting of the lift regarding a heavy method.
まず、揚重ウィンチ１３を起動し、牽引ロープ１８を揚重ウィンチ１３のウィンチドラムにて２００ｍ全量を巻き取れば揚重貨物（エレベーター巻上機２３）は６７ｍ引き上げられ（３：１の減速によって）、エレベーターホール中間階１（下層階）２まで揚重することができる。 First, when the lifting winch 13 is started and the tow rope 18 is wound up by the winch drum of the lifting winch 13 to 200 m in total, the lifting cargo (elevator hoisting machine 23) is lifted 67m (by 3: 1 deceleration) ), It can be lifted up to elevator hall middle floor 1 (lower floor) 2.
揚重貨物（エレベーター巻上機２３）は、エレベーター中間階１の下層階２のレベルよりも１〜２ｍ上まで揚重したところで、吊持状態で静止させる（図３を参照）。その後、下層階２の床上に貨物仮受け用受け材（中間階仮置き構台：Ｈ鋼）２４を配置し、この中間階仮置き構台２４を塔内７へ順次送り込み、アンカーボルト固定Ｌ型鋼からなる支持材１２に固定する。 The lifted cargo (elevator hoisting machine 23) is suspended in a suspended state when it is lifted 1 to 2 m above the level of the lower floor 2 of the elevator intermediate floor 1 (see FIG. 3). Thereafter, a receiving material for temporary cargo reception (intermediate floor temporary gantry: H steel) 24 is arranged on the floor of the lower floor 2, and the intermediate floor temporary gantry 24 is sequentially fed into the tower 7 to fix the anchor bolt fixing L-shaped steel. It fixes to the support material 12 which becomes.
中間階仮置き構台２４を支持材１２に固定できた後で、揚重機ウィンチ１３を巻き下げ、中間階仮置き構台２４上に揚重貨物（エレベーター巻上機２３）を仮置きする（図４を参照）。ここで、エレベーター巻上機２３を仮置きする仮置き構台２４と支持材１２とを支持機構部とも称する。 After the intermediate floor temporary gantry 24 can be fixed to the support member 12, the lifting machine winch 13 is lowered, and the lifted cargo (elevator hoist 23) is temporarily placed on the intermediate floor temporary gantry 24 (FIG. 4). See). Here, the temporary placement gantry 24 for temporarily placing the elevator hoisting machine 23 and the support member 12 are also referred to as a support mechanism section.
上述した仮置き後、揚重機ウィンチ１３を下段の懸垂ロープ２０の長さ分（全揚程５の１／３）だけ巻き下げるように稼働し、下段の懸垂ロープ２０を取り外して回収し、より上段の懸垂ロープ２１を玉掛けロープ２２に直接接続する（図５を参照）。 After the temporary placement described above, the hoist winch 13 is operated so as to be wound down by the length of the lower suspension rope 20 (1/3 of the total lifting height 5), and the lower suspension rope 20 is removed and collected, and the upper The suspension rope 21 is directly connected to the sling rope 22 (see FIG. 5).
次に、本発明の実施形態に係る巻上機揚重方法によって、再度、エレベーター巻上機２３をエレベーターホール中間階２である上層階３まで揚重する工程について、図６〜図８を参照しながら以下説明する。図６は本実施形態に係る巻上機揚重方法に関する揚程の２／３揚重時の中間階２である上層階３における重量貨物の配置構成を示す図であり、図７は本実施形態に係る巻上機揚重方法に関する揚程の２／３揚重時の上層階３における重量貨物の仮置きの構成を示す図であり、図８は本実施形態に係る巻上機揚重方法に関する揚程の２／３揚重時の揚重終了における懸垂ロープの掛け方の構成を示す図である。 Next, referring to FIGS. 6 to 8 for the process of lifting the elevator hoisting machine 23 to the upper floor 3 which is the elevator hall middle floor 2 again by the hoisting machine lifting method according to the embodiment of the present invention. However, it will be described below. FIG. 6 is a diagram showing an arrangement configuration of heavy cargo on the upper floor 3, which is the intermediate floor 2 at the time of 2/3 lifting of the lifting distance related to the hoisting machine lifting method according to the present embodiment, and FIG. It is a figure which shows the structure of the temporary placement of the heavy cargo in the upper floor 3 at the time of 2/3 lifting of the lift regarding the hoisting machine lifting method which concerns on FIG. 8, FIG. 8 is related with the hoisting machine lifting method which concerns on this embodiment It is a figure which shows the structure of how to hang a suspension rope in the completion | finish of lifting at the time of 2/3 lifting of a lift.
図６に示すように、揚重機ウィンチ１３によって再度、牽引ロープ１８を２００ｍ巻き上げれば揚重貨物（エレベーター巻上機２３）は、エレベーターホール中間階２である上層階３まで揚重される。このとき、揚重貨物（エレベーター巻上機２３）は、エレベーター中間階２の上層階３のレベルよりも１〜２ｍ上まで揚重したところで、吊持状態で静止させる（図６を参照）。 As shown in FIG. 6, when the towing rope 18 is again wound up by 200 m by the lifting machine winch 13, the lifting cargo (elevator hoisting machine 23) is lifted to the upper floor 3 that is the elevator hall middle floor 2. At this time, the lifted cargo (elevator hoisting machine 23) is suspended in a suspended state when it is lifted up to 1 to 2 m above the level of the upper floor 3 of the elevator intermediate floor 2 (see FIG. 6).
その後、上層階３の床上に貨物仮受け用受け材（中間階仮置き構台：Ｈ鋼）２４を配置し、この中間階仮置き構台２４を塔内７へ順次送り込み、アンカーボルト固定Ｌ型鋼からなる支持材１２に固定する。これで、中間階仮置き構台２４を支持材１２に固定できたので、揚重ウィンチ１３を巻き下げ、中間階仮置き構台２４上に揚重貨物（エレベーター巻上機２３）を仮置きする（図７を参照）。 After that, a temporary freight receiving receiving material (intermediate floor temporary gantry: H steel) 24 is arranged on the floor of the upper floor 3, and the intermediate floor temporary gantry 24 is sequentially fed into the tower 7 to fix the anchor bolt fixing L-shaped steel. It fixes to the support material 12 which becomes. Now that the intermediate floor temporary gantry 24 has been fixed to the support material 12, the lifting winch 13 is lowered, and the lifted cargo (elevator hoisting machine 23) is temporarily placed on the intermediate floor temporary gantry 24 ( (See FIG. 7).
上述した仮置き後、揚重機ウィンチ１３を上段の懸垂ロープ２１の長さ分（全揚程５の１／３）だけ巻き下げるように稼働し、上段の懸垂ロープ２１を取り外して回収し、動滑車１７の下部を玉掛けロープ２２に直接接続する（図８を参照）。 After the temporary placement described above, the hoisting machine winch 13 is operated so as to be lowered by the length of the upper suspension rope 21 (1/3 of the total lifting height 5), the upper suspension rope 21 is removed and recovered, and the moving pulley The lower part of 17 is directly connected to the sling rope 22 (see FIG. 8).
最後に、本発明の実施形態に係る巻上機揚重方法によって、エレベーター巻上機２３を塔内頂部の機械室９まで揚重する工程について、図９を参照しながら以下説明する。図９は本実施形態に係る巻上機揚重方法に関する重量貨物（エレベーター巻上機）の最上階機械室９への設置完了を示す構成図である。 Finally, the process of lifting the elevator hoisting machine 23 to the machine room 9 at the top of the tower by the hoisting machine lifting method according to the embodiment of the present invention will be described below with reference to FIG. FIG. 9 is a block diagram showing the completion of installation of heavy cargo (elevator hoisting machine) in the uppermost machine room 9 related to the hoisting machine lifting method according to the present embodiment.
図９に示すように、揚重機ウィンチ１３によって再度、牽引ロープ１８を２００ｍ巻き上げれば揚重貨物（エレベーター巻上機２３）は、機械室９まで揚重される。 As shown in FIG. 9, the lifted cargo (elevator hoisting machine 23) is lifted up to the machine room 9 when the towing rope 18 is again wound up by 200 m by the lifting machine winch 13.
以上のように、本発明の実施形態に係る巻上機揚重方法によれば、複数に分割可能な懸垂ロープを分割使用してエレベーター巻上機２３を揚重するとともに、中間階１と中間階２とでエレベーター巻上機２３を仮置きして、その際に、分割可能な懸垂ロープの一部である下部の懸垂ロープ２０を取り外して、より上部の懸垂口−プ２１をエレベーター巻上機２３に連結し、再度揚重する巻上機の揚重方法としたため、超重量物であるエレベーター巻上機２３を、比較的能力の小さい汎用の揚重ウィンチ１３を使用しても、高高所の建物頂部へエレベーター巻上機２３を揚重可能である。 As described above, according to the hoisting machine lifting method according to the embodiment of the present invention, the elevator hoisting machine 23 is lifted using the suspension rope that can be divided into a plurality of parts, and the intermediate floor 1 and the intermediate floor 1 The elevator hoisting machine 23 is temporarily placed at the second floor, and at that time, the lower suspension rope 20 which is a part of the detachable suspension rope is removed, and the upper suspension gate 21 is lifted up by the elevator. Since the lifting method of the hoisting machine connected to the machine 23 and lifting again is used, the elevator hoisting machine 23, which is a super heavy object, can be used even if the general-purpose lifting winch 13 having a relatively small capacity is used. The elevator hoisting machine 23 can be lifted to the top of a high building.
さらに、揚重に際して、懸垂ロープの分割段数を増やせば５００ｍ又は８００ｍの超超高層建物でも特殊能力の揚重ウィンチを使用することなく、また建築物の補強をすることなく、超重量物であるエレベーターの巻上機を高高所の機械室まで揚重することが可能となる。 Furthermore, when lifting, if the number of divisions of the suspension rope is increased, even a 500m or 800m super high-rise building is a super heavy object without using a special capacity lifting winch and without reinforcing the building. The elevator hoisting machine can be lifted up to a high altitude machine room.
