CONTROL DEVICE OF GRIPPING-TYPE HOLE DIGGING AND POLE ERECTING VEHICLE

OKAYASU YOSHIKIMI

To provide a control device of a gripping-type hole digging and pole erecting vehicle capable of expanding applications of a gripping device.SOLUTION: A gripping-type hole digging and pole erecting vehicle comprises: a boom provided on a vehicle body; a gripping portion having a pair of gripping claws that can be opened and closed for gripping a columnar object; a support mechanism that changes a posture of the gripping portion with respect to a tip of the boom; a column extractor that pulls out the columnar object placed on the ground according to expansion and contraction operations of a column extractor cylinder 41; and an operation control portion 102 that controls operations of the boom, the gripping portion, the support mechanism, and the column extractor according to operations of an operation device 31. The operation control portion 102 can pull out the columnar object placed on the ground using the column extractor by extending the column extractor cylinder 41 in a state where the gripping of the columnar object by the gripping portion is relaxed.SELECTED DRAWING: Figure 11

【課題】把持装置の用途を拡大することのできる把持式穴掘建柱車の制御装置を提供する。【解決手段】把持式穴掘建柱車は、車体上に設けられたブームと、柱状物を把持するための開閉可能な一対の把持爪を有する把持部と、ブームの先端部に対する把持部の姿勢を変化させる支持機構と、抜柱機シリンダ４１の伸縮作動に応じて地面に設置された柱状物を引き抜く抜柱機と、操作装置３１の操作に応じて、ブーム、把持部、支持機構および抜柱機の作動を制御する作動制御部１０２とを備え、作動制御部１０２は、把持部による柱状物の把持を緩和させた状態で抜柱機シリンダ４１を伸長作動させることで、地面に設置された柱状物を抜柱機により引き抜き可能に構成される。【選択図】図１１
