The lower leader is rotatably mounted, and the lower leader undulating cylinder and the upper leader undulating cylinder are connected to the lower leader and upper leader, respectively, to form a four-bar link, so when storing and installing the leader,
From the storage position of the leader to the intermediate position, the leader can be raised and lowered using only the lower leader hoisting cylinder, and between the intermediate position and the installation position of the leader, only the upper leader hoisting cylinder is used, Since the leader can be raised and lowered, the movement of the leader is simplified, and the storage and installation of the leader can be carried out safely and easily, and the hydraulic circuits of the upper and lower leader raising and lowering cylinders can be significantly reduced. It can be simplified and lowered in price, and since the upper leader undulating cylinder can substitute for the backstay, the backstay that was previously required is no longer necessary, and the work of inserting and removing the backstay pin, which required manual labor, can be eliminated. It is possible to achieve various excellent effects such as being able to save labor in storage and installation work.
