PROBLEM TO BE SOLVED: To provide a re-hanging method of an auxiliary hoist rope capable of re-hanging the auxiliary hoist rope for an earth drill from single-rope winding to twin-rope winding safely without causing a boom to fall.SOLUTION: There is provided a re-hanging method of an auxiliary hoist rope for re-hanging an auxiliary hoist rope 35 of an earth drill 11 from the state of single-rope winding of connecting an auxiliary hoist hook 36 to the tail of the auxiliary hoist rope 35, to a twin rope winding of winding the auxiliary hoist rope 35 around a sheave 38 of an auxiliary hoist hook 37 with a sheave. Here, in the earth drill 11, a main winding sheave 27 wound with a main hoist rope 31 with a swivel 32 attached to the tip and an auxiliary winding sheave 28 wound with the auxiliary hoist rope 35 whose tip is connected to the auxiliary hoist hook 36, are rotatably attached to a sheave shaft 26 arranged on the tip part of a boom 15 disposed on a base machine 14. Therein, the main hoist rope 31 and the auxiliary hoist rope 35 are wound down to the ground, the main wound rope 31 and the auxiliary hoist rope 35 are wound down to the ground, the auxiliary hoist rope 35 is detached from the auxiliary hoist hook 36, the auxiliary hoist rope 35 is wound around the sheave 38 of the auxiliary hoist hook 37 with sheave and the hipping of the auxiliary hoist rope 35 is connected to the swivel 32.

    【課題】ブームを倒すことなく、安全に、アースドリルの補巻ロープを1本掛けから2本掛けに掛け替えることができる補巻ロープ掛け替え方法を提供する。【解決手段】 ベースマシン14に設けられたブーム15の先端部に配置されたシーブ軸26に、先端にスイベル32を取り付けた主巻ロープ31が巻掛けられる主巻シーブ27と先端に補巻フック36を連結した補巻ロープ35が巻掛けられる補巻シーブ28とを回転可能に取り付けたアースドリル11の補巻ロープ35を尻手に補巻フック36を連結した1本掛けの状態からシーブ付き補巻フック37のシーブ38に巻掛けた2本掛けに掛け替える補巻ロープ掛け替え方法であって、主巻ロープ31及び補巻ロープ35を地上まで巻下げ、補巻フック36から補巻ロープ35を取り外し、補巻ロープ35をシーブ付き補巻フック37のシーブ38に巻掛け、補巻ロープ35の尻手をスイベル32に連結させる。【選択図】図4
