PILE DRIVER COPING WITH SLOPE
Document Type and Number:
Japanese Patent JP2023033270
Kind Code:
A
Abstract:
To provide a pile driver capable of suppressing rollover accidents to the minimum and improved in work efficiency, when used on a rough terrain or a steep slope of unfavorable conditions which is used as a site for wind power generation or solar power generation, due to shortage of a flat site.SOLUTION: In a pile driver 17 having a pile driving work part 14, a revolving body 15 and a traveling body 16, a power pack 4 fixed to the upper part of a linear shaft 6 of the revolving body 15 moves following telescopic movement of the linear shaft to change a gravity center position. A hydraulic mechanism swings a swing arm 8 fixed to the underside of a turn table 7 of the revolving body 15 around a traveling body link 12, to keep a horizontal state of the revolving body 15 on a slope. The gage of a crawler 10 provided to the traveling body 16 is telescopically formed, the crawler 10 is extended to a valley side by a telescopic cylinder 11, the position of the gravity center of the pile driver 17 is lowered, the pile driver 17 is fixed by an outrigger 9 with a spike, and stabilized on a slope.SELECTED DRAWING: Figure 1
