PROBLEM TO BE SOLVED: To solve difference in detecting angles based on difference in boom turning directions (left/right) generated by structural characteristics of a turning angle detector and enable appropriate setting of a work range.SOLUTION: Booms for working in a work machine with a boom are respectively turned to a minimum turning angle position and a maximum turning angle position in respective left and right turning directions; actual turning angle values in the respective turning angle positions are set as adjustment values; the respective adjustment values are memorized by respective adjustment value memorizing means provided according to the turning directions in work range limiting means of the work machine; and the turning angle detection values individually detected in the left and right directions by using individual adjustment values according to the memorized turning directions so as to set a limit region of the work range.
【課題】旋回角検出器部分の構造上の特性から生じるブーム旋回方向(左/右)の相違に基づく検出角の相違を解消し、また適正な作業範囲の設定を可能とする。【解決手段】ブーム付き作業機における作業用ブームを左右各旋回方向の最小旋回角位置と最大旋回角位置にそれぞれ旋回させ、それら各旋回角位置における実際の旋回角値を調整値とし、それら各調整値を、当該作業機の作業範囲制限手段に旋回方向に応じて設けた各調整値記憶手段に記憶させ、また同記憶させた旋回方向に応じた個別の調整値を用いて左右個別に検出された旋回角検出値を補正し、作業範囲の制限領域を設定するようにした。【選択図】 図4
