Abstract
PURPOSE: To strike in a body to be struck into the earth vertically and efficiently together with an earth by connecting the head of the earth auger directly to the tip of the boom of a crane so as to utilize the action of the boom.
CONSTITUTION: Booms 25 and 26 being extended, an earth auger 2 is made to stand vertical. By using a winch 27, a body 3 to be struck is hung up and a latch piece 21 positioned in the lower end thereof is hooked at a metal fitting 20 for hooking, while the upper end is set to the lateral part of the earth auger 2, being grasped system 12. Next, in case there is another body 3 already struck in, a turning system 8 is operated to decide the position where the auger 2 to be pushed in and the auger screw 6 is rotated in the propelling direction by a rotation driving system. At the same time, the sub-boom 26 is shortened in relation to the main boom 25, while the main boom 25 being rotted downward in relation to the main body 24 of a crane, thereby the downward force being given to the earth auger 2. When the auger reaches the fixed depth, the grasping system 12 is opened and the auger screw 6 is rotated reversely to make booms 25 and 26 operate reversely to the prior operation, therey the thestruck body 3 alone is left in the earth.
