CAISSON TYPE PILE EXCAVATOR
To suppress interference between a rope to be detected for slackness and a slackness detection device.SOLUTION: A caisson type pile excavator 1 includes a first lifting sheave 19 and a first opening/closing sheave 21 that move in the length direction of an arm 10, a second lifting sheave 23 and a second opening/closing sheave 30, a lifting rope 38 wound around the first lifting sheave 19 and the second lifting sheave 23, an opening/closing rope 39 wound around the first opening/closing sheave 21 and the second opening/closing sheave 30, and slackness detection device 47 (62) that detects the slackness of the detected rope among the lifting rope 38 and the opening/closing rope 39. The slackness detection device 47 (62) is arranged inside a lifting rope path 38C formed by the lifting rope 38 wound around the first lifting sheave 19 and the second lifting sheave 23, and/or it is arranged inside an opening/closing rope path 39C formed by the opening/closing rope 39 wound around the first opening/closing sheave 21 and the second opening/closing sheave 30.SELECTED DRAWING: Figure 6
【課題】緩みの検出対象となる被検出ロープと緩み検出装置との干渉を抑える。【解決手段】深礎掘削機１は、アーム１０の長さ方向に移動する第１昇降用シーブ１９および第１開閉用シーブ２１と、第２昇降用シーブ２３および第２開閉用シーブ３０と、第１昇降用シーブ１９と第２昇降用シーブ２３とに巻回された昇降ロープ３８と、第１開閉用シーブ２１と第２開閉用シーブ３０とに巻回された開閉ロープ３９と、昇降ロープ３８および開閉ロープ３９のうち被検出ロープの緩みを検出する緩み検出装置４７（６２）とを備える。緩み検出装置４７（６２）は、第１昇降用シーブ１９と第２昇降用シーブ２３とに巻回された昇降ロープ３８が形成する昇降ロープ経路３８Ｃの内側、およびまたは第１開閉用シーブ２１と第２開閉用シーブ３０とに巻回された開閉ロープ３９が形成する開閉ロープ経路３９Ｃの内側に配置される。【選択図】図６
