專業整流控制設備頂桿式自動永磁起重器卸料狀態時：起重機吊鉤再次下降，吊攀隨著下降，吊攀下降到磁本體頂部后，再次向上提升吊環，吊攀帶動棘輪旋轉，便棘輪旋轉到凸起位置，并棘輪凸點將頂桿向下壓，在杠桿的作用下，整流控制設備生產廠家將頂(ding)桿式自動永磁起重器的(de)磁本(ben)體(ti)與被吸鋼板頂(ding)開，完成(cheng)卸料。

永(yong)磁(ci)(ci)吸吊器的(de)兩條轉(zhuan)動(dong)臂的(de)下端(duan)，各(ge)連(lian)著(zhu)一(yi)組(zu)棘(ji)(ji)(ji)爪(zhua)和(he)棘(ji)(ji)(ji)輪(lun)，分(fen)別帶動(dong)各(ge)自的(de)主軸。因此，在操作過(guo)程中應注意(yi)兩根(gen)主軸的(de)同(tong)(tong)(tong)步問題(ti)。每根(gen)主軸的(de)一(yi)端(duan)設有一(yi)塊三角(jiao)(jiao)(jiao)形(xing)指示(shi)板。三角(jiao)(jiao)(jiao)形(xing)指示(shi)板上(shang)各(ge)有一(yi)只角(jiao)(jiao)(jiao)涂成(cheng)綠(lv)(lv)(lv)色(se)。帶有綠(lv)(lv)(lv)色(se)的(de)角(jiao)(jiao)(jiao)方向必須一(yi)致(zhi)。當帶有綠(lv)(lv)(lv)色(se)的(de)角(jiao)(jiao)(jiao)同(tong)(tong)(tong)時朝上(shang)時，永(yong)磁(ci)(ci)起重(zhong)器處(chu)于生磁(ci)(ci)狀態，可以起吊物件。當帶有綠(lv)(lv)(lv)色(se)的(de)角(jiao)(jiao)(jiao)同(tong)(tong)(tong)時朝下時，永(yong)磁(ci)(ci)起重(zhong)器處(chu)于退磁(ci)(ci)狀態，已經(jing)卸料。如果三角(jiao)(jiao)(jiao)形(xing)指示(shi)板上(shang)帶有綠(lv)(lv)(lv)色(se)的(de)角(jiao)(jiao)(jiao)方向不一(yi)致(zhi)，則(ze)表明兩根(gen)主軸不同(tong)(tong)(tong)步。這時必須進行人工干預，用扳手扳動(dong)軸帶一(yi)端(duan)的(de)棘(ji)(ji)(ji)爪(zhua)轉(zhuan)動(dong)-次，讓兩根(gen)主軸同(tong)(tong)(tong)步后(hou)才能投入(ru)工作。同(tong)(tong)(tong)步標志沒有同(tong)(tong)(tong)步時，不能使用。吸盤不退磁(ci)(ci)、磁(ci)(ci)極不同(tong)(tong)(tong)步的(de)處(chu)理(li)方法。

選型(xing)時還(huan)應考慮使用(yong)現場行車的額定載重(zhong)量(liang)和高(gao)度(du)。被(bei)吸(xi)吊(diao)(diao)鋼(gang)板或工件重(zhong)量(liang)加上起重(zhong)永(yong)(yong)磁(ci)鐵(tie)的重(zhong)量(liang)，應在(zai)行車的額定載重(zhong)以內。行車高(gao)度(du)不夠(gou)，則有可能影響起重(zhong)永(yong)(yong)磁(ci)鐵(tie)組(zu)合聯吊(diao)(diao)的使用(yong)。高(gao)溫(wen)會造成起重(zhong)永(yong)(yong)磁(ci)鐵(tie)磁(ci)力(li)急劇衰減，且無(wu)法恢復。因此，被(bei)吸(xi)吊(diao)(diao)鋼(gang)板或工件溫(wen)度(du)應在(zai)-20℃~100C范圍(wei)內。如(ru)果(guo)需要吊(diao)(diao)運高(gao)溫(wen)工件，應定制高(gao)溫(wen)型(xing)起重(zhong)永(yong)(yong)磁(ci)鐵(tie)。

整流控制設備生產廠家起重永磁鐵可以分為以下幾類：手動卸料分為：永磁起重器（手柄垂直轉動式）、永磁吸吊器（手柄水平轉動式）、插銷式起重永磁鐵（手動插銷式）?； 整流控制設備生產廠家自(zi)動卸料分(fen)為：自(zi)卸式(shi)(shi)永(yong)(yong)磁(ci)(ci)(ci)吸吊(diao)器（頂桿(gan)式(shi)(shi)）、變換磁(ci)(ci)(ci)路(lu)(lu)式(shi)(shi)； 變換磁(ci)(ci)(ci)路(lu)(lu)式(shi)(shi)又(you)根據(ju)磁(ci)(ci)(ci)路(lu)(lu)旋轉機(ji)構的不同，分(fen)為自(zi)卸式(shi)(shi)起重(zhong)永(yong)(yong)磁(ci)(ci)(ci)鐵(tie)(tie)（機(ji)械(xie)自(zi)卸式(shi)(shi)）、搬鐵(tie)(tie)器（磁(ci)(ci)(ci)路(lu)(lu)水(shui)平自(zi)卸式(shi)(shi)）、電控(kong)式(shi)(shi)起重(zhong)永(yong)(yong)磁(ci)(ci)(ci)鐵(tie)(tie)、液壓控(kong)制式(shi)(shi)起重(zhong)永(yong)(yong)磁(ci)(ci)(ci)鐵(tie)(tie)、扇形齒(chi)輪傳動起重(zhong)永(yong)(yong)磁(ci)(ci)(ci)鐵(tie)(tie)；
