PROBLEM TO BE SOLVED: To provide a slope work vehicle capable of drilling a lock bolt insertion hole orthogonal to a slope surface at right and left locations of a worked portion, without moving the work vehicle body right and left.SOLUTION: A slope work vehicle 1 includes: a work vehicle body 3; a tire fitting part 4 provided on right and left portions of the work vehicle body 3; a tire fitting part expansion/contraction mechanism 5 capable of expanding/contracting the tire fitting part 4 to suit a width of a slope frame; a tire 7 installed at front and rear portions of the right and left tire fitting parts 4, respectively through a cylinder 6 that may be expanded/contracted in a vertical direction; a winch 8 fitted on the work vehicle body 3; an arm 9 provided rotatably in right-left direction on the work vehicle body 3; a support platform 10 provided rotatably in the right-left direction at a tip part of the arm 9; a guide shell fitting part 11 provided rotatably in the vertical direction on the support platform 10; a guide shell 12 fixed on the guide shell fitting part 11; and a drilling device 13 provided movably in a front-rear direction on the guide shell 12.SELECTED DRAWING: Figure 1
【課題】作業車本体を左右に移動させなくても作業部位の左右の位置に、法面と直交するロックボルト挿入孔を削孔できる法面作業車を提供する。【解決手段】作業車本体3と、作業車本体3の左右部位に設けられたタイヤ取付部4と、タイヤ取付部4を法枠の幅に合わせて伸縮させることができるタイヤ取付部伸縮機構5と、左右のタイヤ取付部4の前後部位に、それぞれ上下方向に伸縮可能なシリンダー6を介して設けられたタイヤ7と、作業車本体3に取り付けられたウインチ8と、作業車本体3に左右方向に回動可能設けられたアーム9と、アーム9の先端部に左右方向に回動可能に設けられた支持台10と、支持台10に上下方向に回動可能に設けられたガイドシェル取付部11と、ガイドシェル取付部11に固定されたガイドシェル12と、ガイドシェル12に前後方向に移動可能に設けられた削孔装置13とで法面作業車1を構成している。【選択図】図1
