Abstract
Description
本発明は、台車に関し、より詳細には、建設廃材の運搬に適した台車に関する。 The present invention relates to a carriage, and more particularly to a carriage suitable for transporting construction waste.
従来、地下鉄駅構内をリニューアルするための解体工事において発生する大量のガラは、作業員が重いガラ袋（約２０キロ）を抱えて階段を何度も往復することで地上に運び出していた。しかしながら、多いときで１人当たり１トン近くのガラを搬出しなければならない日もあり、作業員にとって、このガラの搬出作業が大きな負担となっていた。 Conventionally, a large amount of galley generated in the demolition work for renewal of the subway station yard was carried to the ground by the operator repeatedly carrying stairs back and forth with heavy sack (about 20 km). However, there are days when it is necessary to carry out nearly 1 ton of galley per person, and this galley unloading work has been a heavy burden for workers.
この点につき、特開平８−７３１９９号公報（特許文献１）は、階段の傾斜面に沿って設置した仮設レール上に運搬台車を走行させて重量物を運搬する重量物運搬装置を開示する。しかしながら、特許文献１のような装置は、非常な大がかりなものになる上、仮設レールの組立・解体に多くの時間を要するため、終電から始発までの短い合間を縫って作業しなければならない地下鉄駅構内工事にこれを適用することは現実的ではない。 In this regard, Japanese Patent Application Laid-Open No. 8-73199 (Patent Document 1) discloses a heavy goods transporting apparatus that transports heavy goods by running a transport carriage on a temporary rail installed along an inclined surface of a staircase. However, the apparatus as disclosed in Patent Document 1 becomes very large and requires a lot of time to assemble and disassemble the temporary rail, so the subway must be sewn between the last train and the first train. It is not realistic to apply this to the construction of the station.
本発明は、上記従来技術における課題に鑑みてなされたものであり、本発明は、建設廃材の運搬に適した台車および当該台車を用いた建設廃材の運搬方法を提供することを目的とする。 This invention is made | formed in view of the subject in the said prior art, and this invention aims at providing the trolley | bogie suitable for conveyance of construction waste materials, and the conveyance method of construction waste materials using the said trolley | bogie.
本発明者は、建設廃材の運搬に適した台車および当該台車を用いた建設廃材の運搬方法につき鋭意検討した結果、以下の構成に想到し、本発明に至ったのである。 As a result of intensive studies on a cart suitable for transporting construction waste and a method for transporting construction waste using the cart, the present inventors have conceived the following configuration and have reached the present invention.
すなわち、本発明によれば、建設廃材の運搬に適した台車であって、略長方形の形状を有する台座と、前記台座の上面の前後に固定される前方荷枠および後方荷枠と、前記台座の底面に並設される複数のキャスター列であって、各キャスター列は複数のキャスターが前記台座の長手方向に沿って等間隔に配置されてなる、複数のキャスター列と、を含み、前記複数のキャスター列は、各前記キャスター列に属するキャスターの車輪の回転軸方向が他の前記キャスター列に属するキャスターの車輪の回転軸方向に重ならない態様で並設され、前記台座の長手方向において最も近接する２つの前記キャスターの車輪の軸間距離が該車輪の直径よりも小さいことを特徴とする、台車が提供される。 That is, according to the present invention, a trolley suitable for transporting construction waste, a pedestal having a substantially rectangular shape, a front cargo frame and a rear cargo frame fixed before and after the upper surface of the pedestal, and the pedestal A plurality of caster rows arranged in parallel on the bottom surface of each of the caster rows, wherein each caster row includes a plurality of caster rows in which a plurality of casters are arranged at equal intervals along a longitudinal direction of the base. The caster rows of the casters are arranged side by side in such a manner that the rotation axis directions of the caster wheels belonging to each of the caster rows do not overlap with the rotation axis directions of the caster wheels belonging to the other caster rows, and are closest to each other in the longitudinal direction of the pedestal A cart is provided in which the distance between the axes of the two wheels of the caster is smaller than the diameter of the wheels.
上述したように、本発明によれば、建設廃材の運搬に適した台車および当該台車を用いた建設廃材の運搬方法が提供される。 As described above, according to the present invention, a cart suitable for transporting construction waste and a method for transporting construction waste using the cart are provided.
以下、本発明を図面に示した実施の形態をもって説明するが、本発明は、図面に示した実施の形態に限定されるものではない。なお、以下に参照する各図においては、共通する要素について同じ符号を用い、適宜、その説明を省略するものとする。 Hereinafter, the present invention will be described with reference to embodiments shown in the drawings, but the present invention is not limited to the embodiments shown in the drawings. In the drawings referred to below, the same reference numerals are used for common elements, and the description thereof is omitted as appropriate.
図１は、本発明の実施形態である建設廃材運搬用台車１０（以下、単に、台車１０という）を示す。図１に示すように、本実施形態の台車１０は、台座１２と、前方荷枠１４と、後方荷枠１６とを含んで構成されている。ここで、台座１２は略長方形の形状を有しており、その上面の両端の短辺に沿って、台車１０の進行方向前後に、前方荷枠１４および後方荷枠１６が固設されている。その結果、台車１０は、略コの字状の側面形状を備えている。 FIG. 1 shows a construction waste material carriage 10 (hereinafter simply referred to as a carriage 10) according to an embodiment of the present invention. As shown in FIG. 1, the cart 10 of this embodiment includes a pedestal 12, a front cargo frame 14, and a rear cargo frame 16. Here, the pedestal 12 has a substantially rectangular shape, and a front cargo frame 14 and a rear cargo frame 16 are fixedly provided on the front and rear of the carriage 10 along the short sides of both ends of the upper surface thereof. . As a result, the carriage 10 has a substantially U-shaped side shape.
本実施形態では、作業者が後方荷枠１６を押して台車１０を走行させることを前提とするので、後方荷枠１６の高さＨ１は、作業者が立った状態で把持しやすい適切な高さとすることが好ましい。一方、前方荷枠１４の高さＨ２は、後方荷枠１６の高さＨ１よりも低い高さとすることができ、例えば、高さＨ１の半分程度の高さとすることができる。 In the present embodiment, since it is assumed that the operator pushes the rear cargo frame 16 and causes the carriage 10 to travel, the height H 1 of the rear cargo frame 16 is set to an appropriate height that is easy to grip while the operator is standing. Preferably. On the other hand, the height H 2 of the front loading frame 14 may be lower than the height H 1 of the rear luggage frame 16 height, for example, may be about half of the height of the height H 1.
さらに、前方荷枠１４の中央には、鉛直方向に延びる柱１４ａが前方荷枠１４に架け渡される形で固定されている。本実施形態においては、この柱１４ａに玉掛けワイヤーを巻きつけ、これにケーブルをフック掛けするなどして、台車１０と牽引装置（後述する）を連結する。 Further, a column 14 a extending in the vertical direction is fixed to the center of the front cargo frame 14 so as to be bridged over the front cargo frame 14. In the present embodiment, a dolly wire is wound around the pillar 14a, and a cable is hooked on this to connect the carriage 10 and a traction device (described later).
ここで、本実施形態では、建設廃材をフレコンバッグ（大型のガラ袋）に詰めた荷姿で運搬することを想定している。そのため、フレコンバッグの荷積み・荷下ろしの容易性に鑑みて、台車１０の台座１２の上面両端の長辺にはあえて荷枠を設けていない。また、その台座１２は、フレコンバッグを安定して支持するため必要な最低限のスペースだけを幅方向の両端に残し、その余の部分（中央部分）を開口部とすることで台車１０の軽量化を実現している。 Here, in the present embodiment, it is assumed that construction waste is transported in a packed form packed in a flexible container bag (large-sized glass bag). Therefore, in view of the ease of loading and unloading the flexible container bag, no load frame is provided on the long sides of both ends of the upper surface of the base 12 of the carriage 10. Further, the pedestal 12 leaves only the minimum space necessary for stably supporting the flexible container bag at both ends in the width direction, and the remaining portion (center portion) is used as an opening to reduce the weight of the carriage 10. Has been realized.
一方、台座１２の底面には、複数の固定式キャスター１８が台座１２の長手方向に沿って配設されている。図１に示す例では、台座１２の底面の幅方向両端部の各スペースに対し、複数（図１の場合、９個）のキャスター１８が直線状に等間隔に配置されてなる列（以下、キャスター列という）が３列平行する形で並設されており、全部で６列のキャスター列が台座１２の底面に固定されている。 On the other hand, a plurality of fixed casters 18 are disposed on the bottom surface of the pedestal 12 along the longitudinal direction of the pedestal 12. In the example shown in FIG. 1, a plurality of (9 in the case of FIG. 1) rows of casters 18 arranged in a straight line at equal intervals (hereinafter referred to as “near” in the case of FIG. 1) for each space at both ends in the width direction of the bottom surface of the base 12 The caster rows are arranged in parallel with each other in three rows, and a total of six caster rows are fixed to the bottom surface of the base 12.
ここで、本実施形態におけるキャスター１８の配列態様を図２に基づいて説明する。図２（ａ）は、台座１２の底面に固定される３列のキャスター列の拡大図であり、図２（ｂ）は、図２（ａ）に示した４つのキャスター（イ）、（ロ）、（ハ）、（ニ）につき、それぞれの車輪のみを側面から見た図を示す。 Here, the arrangement | positioning aspect of the caster 18 in this embodiment is demonstrated based on FIG. FIG. 2A is an enlarged view of three caster rows fixed to the bottom surface of the pedestal 12, and FIG. 2B shows the four casters (A) and (B) shown in FIG. ), (C), and (d) show only the wheels viewed from the side.
図２（ａ）に示すように、３列のキャスター列は、各キャスター列に属するキャスター１８の車輪の回転軸方向が他のキャスター列に属するキャスター１８の車輪の回転軸方向に重ならない態様で並設されている。ここで、図２（ａ）に示す４つのキャスター（イ）、（ロ）、（ハ）、（ニ）に着目してみると、４つのキャスター（イ）、（ロ）、（ハ）、（ニ）は、図２（ｂ）に示すように、台座１２の長手方向（すなわち、台車１０の進行方向）において最も近接する２つの車輪の軸間距離Ｐが当該車輪の半径ｒに略等しくなるように位置決めされている。ここで、“台座１２の長手方向において最も近接する２つの車輪”とは、図２（ａ）に示す例では、（イ）と（ロ）、（ロ）と（ハ）、（ハ）と（ニ）がこれに相当し、軸間距離Ｐとは、２つのキャスター１８において、各車輪の回転軸の延長線の離間距離を意味する。 As shown in FIG. 2 (a), the three caster rows are arranged in such a manner that the rotation axis directions of the wheels of the casters 18 belonging to each caster row do not overlap the rotation axis directions of the wheels of the casters 18 belonging to the other caster rows. It is installed side by side. Here, when attention is paid to the four casters (A), (B), (C), and (D) shown in FIG. 2A, the four casters (A), (B), (C), 2D, as shown in FIG. 2B, the inter-axis distance P between the two wheels closest to each other in the longitudinal direction of the base 12 (that is, the traveling direction of the carriage 10) is substantially equal to the radius r of the wheel. It is positioned so that Here, “two wheels closest to each other in the longitudinal direction of the pedestal 12” are (a) and (b), (b) and (c), and (c) in the example shown in FIG. (D) corresponds to this, and the inter-axis distance P means the separation distance between the extension lines of the rotating shafts of the wheels in the two casters 18.
なお、本発明は、軸間距離Ｐを車輪の半径ｒより小さくすることを排除するものではなく、台座１２の底面に並設するキャスター列の数を増すことによって軸間距離Ｐをより小さくすることができる。また、本発明は、軸間距離Ｐを車輪の半径ｒより大きくすることを排除するものではないが、その場合でも、軸間距離Ｐが車輪の直径２ｒを超えないようにすることが望ましい。本実施形態において、軸間距離Ｐは以下の意味を持つ。 The present invention does not exclude the reduction of the inter-axis distance P from the wheel radius r, but the reduction of the inter-axis distance P by increasing the number of caster rows arranged on the bottom surface of the base 12. be able to. Further, the present invention does not exclude that the inter-axis distance P is larger than the wheel radius r, but even in that case, it is desirable that the inter-axis distance P does not exceed the wheel diameter 2r. In the present embodiment, the inter-axis distance P has the following meaning.
台車１０の進路に段差が存在する場合、図３に時系列的に示すように、台座１２の底面に固定されたキャスター１８の車輪は、１列目→２列目→３列目→１列目→２列目→３列目→１列目…といった順番で段差の角に乗り上げる。このとき、台車１０の進行方向において最も近接する２つの車輪（すなわち、段差の角に連続して乗り上げる２つの車輪）の軸間距離Ｐが当該車輪の直径２ｒを超えていると、何かの拍子に２つのキャスター１８の間に段差の角が嵌り込んで身動きが取れなくなる虞がある。この点につき、軸間距離Ｐを車輪の半径ｒに略等しくしておけば、そのような事態が好適に回避され、台車１０をスムースに走行させることができる。さらに、軸間距離Ｐを車輪の半径ｒより小さくすればするほど、台車１０の走行はスムースになる。ただし、軸間距離Ｐを小さくするためには、その分、キャスターが必要となり、その場合、台車１０の製造コストならびに重量が増加する。したがって、軸間距離Ｐは、走行安定性やコスト等に係る要請を総合的に勘案して適切な値に設定することが好ましい。 When there is a step in the course of the carriage 10, the wheels of the casters 18 fixed to the bottom surface of the pedestal 12 are in the first row → second row → third row → one row as shown in FIG. Get on the corner of the step in the order of eyes → 2nd row → 3rd row → 1st row. At this time, if the inter-axis distance P between the two wheels that are closest to each other in the traveling direction of the carriage 10 (that is, the two wheels that continuously ride on the corner of the step) exceeds the diameter 2r of the wheel, There is a possibility that the corner of the step is fitted between the two casters 18 and the movement cannot be performed. In this regard, if the inter-axis distance P is made substantially equal to the radius r of the wheel, such a situation can be suitably avoided, and the carriage 10 can run smoothly. Furthermore, as the inter-axis distance P is made smaller than the wheel radius r, the traveling of the carriage 10 becomes smoother. However, in order to reduce the inter-axis distance P, a caster is required correspondingly, and in that case, the manufacturing cost and weight of the carriage 10 increase. Therefore, it is preferable to set the inter-axis distance P to an appropriate value by comprehensively considering requests related to running stability, cost, and the like.
上述したように、本実施形態の台車１０は、階段をスムースに上り下りすることができる。また、階段の上り下りの際に、各キャスター１８の車輪が点で階段の角に接するので、クローラー駆動の搬送装置に比較して階段を痛めることが少ない。加えて、本実施形態の台車１０は、市販の鉄鋼材とキャスターを溶接することで簡易・安価に作製することができるので、用途に応じて、その構造をカスタマイズすることも可能になる。 As described above, the cart 10 of this embodiment can smoothly go up and down stairs. In addition, when the stairs are going up and down, the wheels of each caster 18 are in contact with the corners of the stairs at points, so that the stairs are less likely to be damaged compared to a crawler-driven transport device. In addition, since the cart 10 of the present embodiment can be easily and inexpensively manufactured by welding a commercially available steel material and casters, the structure can be customized according to the application.
以上、本実施形態の台車１０の構造について説明してきたが、続いて、上述した台車１０を利用した建設廃材の運搬方法について説明する。 As mentioned above, although the structure of the trolley | bogie 10 of this embodiment was demonstrated, the conveyance method of the construction waste material using the trolley | bogie 10 mentioned above is demonstrated.
図４は、本実施形態の建設廃材の運搬方法を説明するための模式図である。本実施形態では、発生した建設廃材を階段を含む搬送経路を経て階上の搬出先まで運搬する。本実施形態では、まず、任意の牽引装置が台車１０を牽引するために用意され、階上に設置される。図４に示す例では、牽引装置として油圧駆動のウィンチ２２を搭載したスキッドステアローダー２０を示している。 FIG. 4 is a schematic diagram for explaining the construction waste transport method according to the present embodiment. In the present embodiment, the generated construction waste is transported to a transport destination on the floor via a transport path including stairs. In the present embodiment, first, an arbitrary towing device is prepared for towing the carriage 10 and installed on the floor. The example shown in FIG. 4 shows a skid steer loader 20 equipped with a hydraulically driven winch 22 as a traction device.
続いて、図４（ａ）に示すように、ウィンチ２２から繰り出されるケーブル２４を介して台車１０の前方荷枠１４（の柱１４ａ）とスキッドステアローダー２０を連結した状態で、後方荷枠１６を階下に向けて台車１０を階段３０の上に載置する。その後、ウィンチ２２からケーブル２４をゆっくりと繰り出しながら、台車１０に階段を下らせて、台車１０を階下にある建設廃材の置き場まで移動させる。 Subsequently, as shown in FIG. 4A, the rear cargo frame 16 is connected to the front cargo frame 14 (the pillar 14a) of the carriage 10 and the skid steer loader 20 via the cable 24 fed out from the winch 22. The carriage 10 is placed on the stairs 30 with the floor facing down. Thereafter, while slowly pulling out the cable 24 from the winch 22, the trolley 10 is moved down the stairs, and the trolley 10 is moved to the construction waste storage place downstairs.
台車１０が目的の置き場に到着すると、そこに集積されている建設廃材（例えば、ガラ）を台車１０の台座１２上においてフレコンバッグに詰める作業を行う。建設廃材の積み込みが完了した時点で、階下の作業員は、台車１０を手押しして階段３０の下まで移動させた後、階上の作業員（スキッドステアローダー２０の操縦者）に合図を送る。これを受けて、階上の作業員は、ウィンチ２２を駆動してケーブル２４をゆっくり巻き上げる。これを受けて、フレコンバッグ４０を積載した台車１０は、図４（ｂ）に示すように、階上方向に牽引されて階段３０を上る。 When the cart 10 arrives at the target storage site, the construction waste material (for example, glass) accumulated there is packed on the base 12 of the cart 10 in a flexible container bag. When the loading of construction waste is completed, the downstairs worker pushes the carriage 10 and moves it to the bottom of the stairs 30, and then sends a signal to the upstairs worker (operator of the skid steer loader 20). . In response to this, the worker on the floor drives the winch 22 to slowly wind up the cable 24. In response to this, the cart 10 loaded with the flexible container bag 40 is pulled up the stairs 30 as shown in FIG. 4B.
台車１０を階段３０の階上まで引き上げた後、スキッドステアローダー２０は、図４（ｃ）に示すように、台車１０を連結した状態で後退して、台車１０を完全に階上に乗り上げさせる。その後、台車１０に積載されたフレコンバッグ４０は、ユニック車などに積み直されて、所定の廃棄場所まで運搬される。 After the carriage 10 is lifted up to the floor of the stairs 30, the skid steer loader 20 moves backward with the carriage 10 connected, as shown in FIG. 4 (c), so that the carriage 10 is completely on the floor. . Thereafter, the flexible container bag 40 loaded on the cart 10 is reloaded on a UNIC vehicle or the like and transported to a predetermined disposal location.
以上、本実施形態の建設廃材の運搬方法について説明してきたが、上述した方法の好適な適用例として、地下鉄駅構内のリニューアル解体工事を挙げることができる。これまで、地下鉄駅構内のリニューアル解体工事に伴って発生する大量のガラは、専ら、人海戦術に頼って地上に運び出していたが、１日当たりの作業時間が３時間程度しか与えられない上に、作業員一人が１日に搬出しなければならないガラの量は１トン近くに及ぶこともあり、ガラの搬出作業は作業員にとって大きな負担となっていた。 As described above, the method for transporting construction waste according to the present embodiment has been described. As a suitable application example of the above-described method, renewal dismantling work in a subway station can be mentioned. Until now, the large amount of galley generated by the renewal dismantling work in the subway station has been carried out to the ground solely by relying on human tactics, but the working time per day is only given for about 3 hours. The amount of glass that one worker has to carry out per day can reach nearly 1 ton, and carrying out the glass is a heavy burden on the worker.
この点につき、本実施形態の方法を使用すれば、図５（ａ）、（ｂ）に示すような態様で、一度に大量のガラを地下から地上へ搬出することができるので、作業員自らが重いガラ袋を抱えて階段を往復する必要がなくなり、作業負担が大幅に軽減される。また、この作業は、台車１０を支える作業員と地上の牽引装置を操作する作業員の２人で行うことができるので、ガラ搬出にかかる工数を大幅に低減することが可能になる。 In this regard, if the method of the present embodiment is used, a large amount of glass can be carried out from the basement to the ground at a time as shown in FIGS. 5 (a) and 5 (b). It is no longer necessary to go up and down the stairs with a heavy glass bag, greatly reducing the work burden. In addition, since this work can be performed by two people, the worker who supports the carriage 10 and the worker who operates the traction device on the ground, the number of man-hours required for carrying out the glass can be greatly reduced.
なお、図５（ａ）、（ｂ）において、ケーブル２４に連結した玉掛けワイヤーが柱１４ａを上下していることに着目されたい。このように、本実施形態においては、状況に応じて、台車１０を牽引する支点が上下に移動して適時最適化されるので、台車１０の安定した牽引が担保される。 Note that in FIGS. 5A and 5B, the sling wires connected to the cable 24 move up and down the column 14a. Thus, in this embodiment, since the fulcrum which pulls the trolley | bogie 10 moves up and down according to a condition and is optimized timely, the stable traction of the trolley | bogie 10 is ensured.
最後に、本実施形態の台車１０の取り回しを容易にするための補助部材について説明する。本実施形態の台車１０の底面に固定されるキャスター１８は、車輪が回転しない固定式のキャスターであるため、重量物を積載している場合には、その取り回しが困難となる。この点につき、本実施形態においては、図６に示す補助部材５０を用いることができる。 Finally, an auxiliary member for facilitating the handling of the carriage 10 of the present embodiment will be described. Since the caster 18 fixed to the bottom surface of the cart 10 according to the present embodiment is a fixed caster in which the wheel does not rotate, handling is difficult when a heavy object is loaded. In this regard, the auxiliary member 50 shown in FIG. 6 can be used in the present embodiment.
図６に示すように、補助部材５０は、２本の足部５２ａ，５２ｂを含むコの字状部材５２と、コの字状部材５２のコの字の縦棒に相当する部分の中央に固定され、コの字に対して垂直方向に延びる棒状部材５４とを含んで構成されている。ここで、２本の足部５２ａ，５２ｂは、後方荷枠１６に形成された２つの嵌合孔１６ａ，１６ｂの位置と大きさに鑑みてこれに合致するように形成されている。 As shown in FIG. 6, the auxiliary member 50 has a U-shaped member 52 including two feet 52 a and 52 b, and a center of a portion corresponding to the U-shaped vertical bar of the U-shaped member 52. And a rod-shaped member 54 that is fixed and extends in a direction perpendicular to the U-shape. Here, the two legs 52a and 52b are formed so as to match with the positions and sizes of the two fitting holes 16a and 16b formed in the rear cargo frame 16.
本実施形態においては、補助部材５０の使用に際し、図７（ａ）に示すように、２本の足部５２ａ，５２ｂのそれぞれを嵌合孔１６ａ，１６ｂに挿嵌して補助部材５０と台車１０を合体する。 In the present embodiment, when the auxiliary member 50 is used, as shown in FIG. 7A, the two foot portions 52a and 52b are inserted into the fitting holes 16a and 16b, respectively, and the auxiliary member 50 and the cart are inserted. Combine 10 together.
次に、図７（ｂ）に示すように、作業員が棒状部材５４の端を持って体重を預けてこれを鉛直方向に押し下げると、テコの原理で台車１０の前方が地面から浮き上がる。このとき、作業員が棒状部材５４に体重を預けた状態で、すかさず、体を移動させると、台車１０が接地するキャスター１８を軸として回転する。その結果、図７（ｃ）に示すように、台車１０が所望の進行方向に向き直る。 Next, as shown in FIG. 7 (b), when the worker holds the end of the rod-shaped member 54 and deposits his / her weight and pushes it down in the vertical direction, the front of the carriage 10 is lifted from the ground by the lever principle. At this time, if the worker moves his / her body without leaving his / her weight in the rod-shaped member 54, the bogie 10 rotates about the caster 18 that contacts the ground. As a result, as shown in FIG. 7C, the carriage 10 turns in the desired traveling direction.
以上、本発明について実施形態をもって説明してきたが、本発明は上述した実施形態に限定されるものではない。例えば、上述した実施形態では、建設廃材をフレコンバッグで運搬するケースを想定していたため、台車１０の台座１２の長辺に荷枠を設けず、また、座部１２中央部分を開口部としていたが、他の実施形態では、台座１２の四辺を荷枠で囲むようにして良いし、台座１２に開口部を設けなくても良い。また、上述した運搬方法は、その原理上、運搬対象を建設廃材に限定するものではなく、任意の重量物の運搬に適用できることはいうまでもない。その他、当業者が推考しうる実施態様の範囲内において、本発明の作用・効果を奏する限り、本発明の範囲に含まれるものである。 Although the present invention has been described with the embodiment, the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, a case in which construction waste is transported with a flexible container bag is assumed. Therefore, no load frame is provided on the long side of the base 12 of the carriage 10, and the central portion of the seat 12 is an opening. However, in other embodiments, the four sides of the pedestal 12 may be surrounded by a cargo frame, and the opening may not be provided in the pedestal 12. Moreover, it cannot be overemphasized that the conveyance method mentioned above does not limit a conveyance object to construction waste material in the principle, but can be applied to conveyance of arbitrary heavy goods. In addition, it is included in the scope of the present invention as long as the effects and effects of the present invention are exhibited within the scope of embodiments that can be considered by those skilled in the art.
