AI Technical Summary
【0008】 本発明によると、ブームおよびジブが地面上に倒伏された状態で、ウインチでロープが巻き取られることで、倒伏されたストラットが起立される。そして、ウインチでロープが巻き取られ、中間部材が接続部に向かって移動された状態で、第2ストラットガイラインの他端が接続部に接続される。中間部材を接続部に向かって移動させることで、第2ストラットガイラインの他端と接続部との間の距離を短くすることができる。よって、第2ストラットガイラインの他端を接続部に接続する作業を容易に行うことができる。また、接続作業を行う際に、中間部材から接続部まで延びた第2ストラットガイラインのみをハンドリングすればよいので、ストラットから接続部まで延びた1本のストラットガイラインをハンドリングする場合に比べて、接続作業を容易に行うことができる。よって、ストラットガイラインをブームの所定位置に接続する作業の作業性を向上させることができる。
