Document Type and Number:
Japanese Patent JP2017154845
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve attachment working property of a post side pendant member and a boom side pendant member.SOLUTION: A post driving device comprises: a link mechanism on which a link side coupling part is provided, the link side coupling part being detachably coupled to a boom side coupling part; and a stretchable actuator whose one end is connected to a rear post, and whose the other end is connected to the other end of the link mechanism. When the stretchable actuator is extended when the link side coupling part and the boom side coupling part are separated, namely in a separation state, the link mechanism rotates to the boom side to a position where the link side coupling part and the boom side coupling part can be coupled, and when the stretchable actuator is shrunk when the link side coupling part and the boom side coupling part are coupled, namely in a coupling state, the link mechanism rotates the rear post to the boom side to a position where one end of the boom side pendant member attached to the boom, and the other end of the post side pendant member attached to the tip end part of the rear post can be connected.SELECTED DRAWING: Figure 7
