PROBLEM TO BE SOLVED: To enable confirmation of whether or not a safety fence as a whole is properly installed and whether or not a safety weight is installed before an operator starts operation, so as to secure safety in maintenance operation.SOLUTION: The safety fence device comprises: first-third panels 1, 2 and 3 which can self-stand by being connected to be combined with one another; first and second weights 8a and 8b for fixing which are connected to any panels 1 and 3 of the panels 1, 2 and 3 to prevent the combined panels 1, 2 and 3 from collapsing; and first-seventh inside wiring 7a-7g which are formed as one closed circuit passing through all panels 1, 2 and 3 and inside of the fixing weights 8a and 8b, when the panels 1, 2 and 3 are formed in a self-standing specified shape by connecting all panels 1, 2 and 3 to the weights 8a and 8b for fixing, which determines whether or not a safety fence 20 is installed in a specified fashion by flowing fine electric currents to the closed circuit and finding presence/absence of conduction of the circuit.SELECTED DRAWING: Figure 1
【課題】安全柵全体が正しく設置されているか否か、作業者が作業前に安全錘を設置したか否の確認を可能とし、保守作業の安全性の確保を図る。【解決手段】連結して組み合わせることにより自立可能な第1ないし第3のパネル1,2,3と、当該パネル1,2,3の任意のパネル1,3の下部に連結され、組み合わされたパネル1,2,3の倒壊を防止する第1及び第2の固定用錘8a,8bと、全てのパネル1,2,3と固定用錘8a,8bを連結し、パネル1,2,3を自立させた規定の形にしたとき、全てのパネル1,2,3と固定用錘8a,8bの内部を通る1つの閉回路として形成される第1〜第7の内部配線7a〜7gと、を備え、前記閉回路に微小電流を流してその導通の有無により安全柵20が規定の形で設置されたか否かを判断する。【選択図】図1
