Description

本発明は、第1の場所に設けられた対となる第1の架台に支持されている長尺の重量物を第2の場所に設けられた対となる第2の架台に載せ換える重量物の載置方法及びそのシステムに関する。
ここで、重量物とは、例えば、橋桁、大型プラントの一部、建築物の一部を指す。
The present invention relates to a heavy article in which a long heavy article supported by a pair of first bases provided at a first place is replaced with a pair of second bases provided at a second place. It is related with the mounting method and its system.
Here, a heavy article refers to a bridge girder, a part of a large plant, and a part of a building, for example.

道路通行止めを伴う橋梁架設工事等では、限られた時間と限られたエリア内で作業を完結することが求められている。このため、架設場所とは離れた場所で組み立てられた橋梁を架設場所まで輸送して、橋脚上等の高所位置に据えつけることが行われていた。
従って、橋梁の据付には、重量物を運搬する輸送設備と、重量物を高所まで持ち上げて据えつける昇降設備の双方が必要不可欠の設備になっていた。しかし、工事の特性、作業コスト、作業効率等を考えると、輸送設備と昇降設備の運用を常に最適条件で行うことは不可能であった。
そこで、重量物を輸送する自走式トランスポーターにジャッキ又はリフター等の重量物専用の昇降設備を積載して、自走式トランスポーターに昇降機能を付加して使用することが提案されている(例えば、特許文献1参照)。
In bridge construction work with road closures, it is required to complete work within a limited time and in a limited area. For this reason, it has been practiced to transport a bridge assembled at a location distant from the installation location to the installation location and install it at a high position on the pier.
Therefore, for installation of bridges, both transportation equipment for transporting heavy objects and lifting equipment for lifting heavy objects up to high places have become indispensable facilities. However, considering the construction characteristics, work costs, work efficiency, etc., it was impossible to always operate the transport equipment and the lifting equipment under the optimum conditions.
Therefore, it has been proposed to use a self-propelled transporter that transports heavy objects with a lifting device dedicated to heavy objects such as a jack or a lifter, and to use the self-propelled transporter with a lifting function ( For example, see Patent Document 1).

特開2001−98512号公報JP 2001-98512 A

しかしながら、特許文献1に記載された昇降機能が付加された自走式トランスポーターでは、昇降設備の昇降範囲(ストローク)が短い(例えば、最大で2100mm)ため、重量物を高所まで持ち上げることができないという問題があった。そこで、橋梁のように架設場所が高所に位置する工事では昇降距離が大きくなるため、重量物を持ち上げるために別途大型のクレーン等の機材を併用する必要があった。
このため、工事コスト、作業時間、作業エリアが大幅に増大するという問題が生じていた。
However, in the self-propelled transporter to which the lifting function described in Patent Document 1 is added, the lifting range (stroke) of the lifting equipment is short (for example, 2100 mm at the maximum), so that a heavy object can be lifted to a high place. There was a problem that I could not. Therefore, in construction where the construction site is located at a high place such as a bridge, the lifting distance becomes large, so it is necessary to use a large crane or other equipment together to lift heavy objects.
For this reason, the problem that construction cost, work time, and work area increase significantly has arisen.

本発明はかかる事情に鑑みてなされたもので、高所に載置された重量物を高所で受け取りその高さを保持した状態で安定を確保しながら運搬し高所に載置することが可能な重量物の載置方法及びそのシステムを提供することを目的とする。 The present invention has been made in view of such circumstances, and can receive a heavy article placed at a high place at a high place, transport it while maintaining its height, and place it at a high place. It is an object of the present invention to provide a method and system for placing possible heavy objects.
