OPERATION LIMITING DEVICE OF CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To cope with interference with a cab of a work machine installed on the tip of an attachment and interference with the cab of a long side object grasped by the work machine, and to also easily install without causing processing such as that having influence on strength of the cab.SOLUTION: An operation limiting device comprises: a striker (4) provided on the indoor side of at least any one of front columns (AP) provided on the front end left-right of a cab (21) arranged in a front end part of a hydraulic excavator and detecting deformation of the front columns (AP); and a limit switch (6) for outputting an indication for stopping specific operation which has risk of further deforming at least the front columns (AP) among operation of the hydraulic excavator when the deformation of the front columns (AP) is detected by the striker (4).
【課題】アタッチメントの先端に取り付けられた作業機のキャブへの干渉や、作業機が掴んだ長尺物のキャブへの干渉に対応するとともに、キャブの強度に影響を与えるような加工を伴うことなく取付けを容易に行う。【解決手段】油圧ショベルの前端部に配置されたキャブ（２１）の前端左右に設けられた前支柱（ＡＰ）の少なくとも何れか一方の室内側に設けられ、前支柱（ＡＰ）の変形を検知するストライカー（４）と、ストライカー（４）により前支柱（ＡＰ）の変形が検知された場合に、油圧ショベルの動作のうち、少なくとも前支柱（ＡＰ）をさらに変形させる恐れのある特定の動作を停止させる指示を出力するリミットスイッチ（６）と、を備える。【選択図】図１
