< Topic >By the fact that judgment mistake of the pilot is alert warned in advance the accident which is made to collide to the drivers cage of the based with the judgment mistake with the visualization of the operator in the work of using guratsupuru of the lumber, machine, with simple configuration, the alarm device of lumber guratsupuru which prevents the generation and huge repair cost of accident is offered.SolutionsIn upper fixed part opposing 7 of lumber guratsupuru device 6 and lower part rotary section 8, it provided perception component 10A. Perception component 10A upper fixed part 7 and lower part rotary section 8 to provide detection target component 11 on the one hand, on the other hand, the log and the like contacting the edge strip section of the operational handling room and with the angle which becomes the dangerous position which has the possibility of breaking the operational handling room, approaching it provided perception component 10A in position the left and right which opposes with detection target component 11.< Choice figure >Drawing 3【課題】木材のグラップルを使った作業において、運転者の目視による判断ミスによりベースマシンの運転室に衝突させる事故を、簡易な構成によって、操縦者の判断ミスを事前に警告することで、事故の発生や多額の修繕費を防止する木材グラップルの警報装置を提供する。【解決手段】木材グラップル装置6の上部固定部7と下部回転部8に対向して感知部材10Aを設けた。感知部材10Aは、上部固定部7と下部回転部8の一方に検出対象部材11を設け、他方に、丸太等が運転操作室の側面部に接触して運転操作室を破損する可能性のある危険位置となる角度で、近接して検出対象部材11と対向する左右の位置に感知部材10Aを設けた。【選択図】図3
