翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Traveling block ： ウィキペディア英語版 Traveling block A traveling block is the freely moving section of a block and tackle that contains a set of pulleys or sheaves through which the drill line (wire rope) is threaded or (reeved ) and is opposite (and under) the crown block (the stationary section). The combination of the traveling block, crown block and wire rope drill line gives the ability to lift weights in the ''hundreds of thousands'' of pounds. On larger drilling rigs, when raising and lowering the derrick, line tensions over a million pounds are not unusual. ==See also== * List of components of oil drilling rigs 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「Traveling block」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.
