用于常規(guī)皮帶輸送機(jī)：地下、索道支撐皮帶輸送機(jī)：輪船裝卸系統(tǒng)；堆垛/取料輸送機(jī)；傾斜和梭式輸送機(jī)；起重機(jī)、挖掘機(jī)，起重臂限位：裙邊給料機(jī)/輸送機(jī)：重型極限開(kāi)關(guān)檢測(cè)膠帶的跑偏量，是實(shí)現(xiàn)膠帶機(jī)控制的自動(dòng)報(bào)警和停機(jī)的保護(hù)裝置。廣泛用于冶金、煤炭、水泥建材、采礦、電力、港埠、冶金、化工等領(lǐng)域的各種帶式輸送設(shè)備。

跑偏開(kāi)關(guān)起帶式輸送現(xiàn)場(chǎng)的保護(hù)作用，因此必須達(dá)到的IP防護(hù)等級(jí)。
開(kāi)關(guān)分兩個(gè)位置檢測(cè)輸送機(jī)皮帶的跑偏程度和扭曲程度。根據(jù)皮帶的跑偏程度和扭曲程度，實(shí)現(xiàn)自動(dòng)報(bào)警和停機(jī)，避免昂貴的輸送皮帶受損壞及因皮帶扭曲造成的物料散落等事故。此開(kāi)關(guān)安裝方便，運(yùn)行可靠，是帶式輸送機(jī)*的保護(hù)裝置之一。
 基本原理　　輸送機(jī)在運(yùn)行中，當(dāng)皮帶跑偏且與開(kāi)關(guān)立輥接觸時(shí)，立輥?zhàn)赞D(zhuǎn)，若跑偏量繼續(xù)加大，則擠壓立輥發(fā)生偏移。一級(jí)開(kāi)關(guān)信號(hào)用于報(bào)警，如果將此信號(hào)與跑調(diào)整裝置相接，即可實(shí)現(xiàn)不停機(jī)狀態(tài)下的跑偏自動(dòng)調(diào)整。二級(jí)開(kāi)關(guān)信號(hào)用于停機(jī)，將此信號(hào)接至控制線路中，即可實(shí)現(xiàn)重度跑偏狀態(tài)下的自動(dòng)停機(jī)。當(dāng)故障排除后，膠帶離開(kāi)立輥正常運(yùn)轉(zhuǎn)時(shí)，立輥可自動(dòng)復(fù)位。
