To provide a safety confirmation method of an arm movement capable of preventing close encounter, contact, and electric shock with the charging part of an arm with a simple and inexpensive configuration.SOLUTION: A safety confirmation method of arm movement is to attach one end 102a of a string-shaped member 102 with a predetermined length to a predetermined position of an arm 101 of a crane vehicle 100, and determines a range in which the arm 101 can safely operate on the basis of the situation where the string member 102 is in contact with the ground 108, when the arm 101 is moved under the state where the string-shaped member 102 hangs down in a vertical direction from the arm 101. A length of the string-shaped member 102 is set to a length at which the other end 102b of the string-shaped member 102 is separated from a ground 108 when the arm 101 enters an inhibition area 106. The safety confirmation method of the arm movement determines that the arm 101 can safely operate when the other end 102b of the string-shaped member 102 is not separated from the ground 108, and gives the instruction to stop the movement of an arm 101 when the other end 102b of the string-shaped member 102 is separated from the ground 108.SELECTED DRAWING: Figure 1B

    【課題】簡易・安価な構成で、アームの充電部に対する接近、接触、感電の防止をすること。【解決手段】クレーン車両100のアーム101の所定の位置に、所定の長さの紐状部材102の一端102aを取り付け、紐状部材102がアーム101から略鉛直方向に垂れ下がった状態で、アーム101を動かす際に、紐状部材102が地上108に接する状況に基づいて、アーム101が安全に動作できる範囲を判断する。紐状部材102の長さが、アーム101が進入禁止領域106に入った場合に、紐状部材102の他端102bが地上108から離れる長さに設定され、紐状部材102の他端102bが地上108から離れていない場合に、アーム101が安全に動作できていると判断し、紐状部材102の他端102bが地上108から離れた場合に、アーム101の動作を中止する指示を出す。【選択図】図1B
