翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Power shovel ： ウィキペディア英語版 Power shovel A power shovel (also stripping shovel or front shovel or electric mining shovel) is a bucket-equipped machine, usually electrically powered, used for digging and loading earth or fragmented rock and for mineral extraction.〔(US Department of the Treasury, IRS: Appendix I - Glossary of Mining Terms )〕 ==Design== Shovels normally consist of a revolving deck with a power plant, driving and controlling mechanisms, usually a counterweight, and a front attachment, such as a crane ("boom") which supports a handle ("dipper" or "dipper stick") with a digger ("bucket") at the end. "Dipper" is also sometimes used to refer to the handle and digger combined. The machinery is mounted on a base platform with tracks or wheels.〔(Encyclopædia Britannica, Power Shovel )〕 Modern bucket capacities range from 8 m3 to nearly 80 m3. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Power shovel」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
