を特徴とするクレーンのモーメントリミッタ。It has an actual load calculation circuit that outputs a load signal based on the force acting on the working arm consisting of a boom and jib combination that lifts and lowers a predetermined load, and sets a limit load corresponding to the type of boom and jib combination. , a limit load setting circuit that outputs a limit load signal, and a changeover switch that is electrically connected to the limit load setting circuit and that specifies a limit load corresponding to the combination of the boom length and jib length. The moment limiter for the crane is configured to set the boom length and jib length in the limit load setting circuit and output a boom length signal and shell length signal, as well as the limit load setting circuit and actual load calculation circuit. are connected to their respective output terminals to transmit the limit load signal and the load signal, or the boom length signal and the jib length signal, respectively.
Each of the selection switches is provided with a selection switch that selectively conducts conduction, and a display device connected to the selection switch and having a first display section and a second display section, and by appropriately switching the changeover switch and the selection switch. The limit load shall be displayed on one of the first display section and the second display section, the load on the other, or the boom length on one and the jib length on the other.
