Loose lock tam sim no: Ua ntej muab cov lus txib xoob xoob, lub inverter yuav tsum xub tsim lub xauv xoob tam sim no. Tam sim no feem ntau yog teem rau ntawm 70% ~ 120% ntawm cov ntsuas lub cev muaj zog tam sim no. Nyob rau hauv dav dav, tam sim no dynamic teb ceev zaus converter, qhov tam sim no tuaj yeem raug teeb tsa qis dua; Tam sim no dynamic teb qeeb zaus converter, qhov tam sim no yuav tsum tau teem siab dua. Lifting mechanism thiab sab nraum zoov crane txhais mechanism, rotary mechanism no tam sim no yuav tsum tau teem siab dua; Sab hauv crane txhais lus mechanism thiab rotary mechanism no tam sim no tuaj yeem teeb tsa qis dua. Tus nqi tam sim no tau teeb tsa qis, lub cev muaj zog torque tsis txaus thaum lub ntsuas phoo xoob, lub tshuab nqa nqa yuav plam qhov tshwm sim ntawm kev sib tsoo (tag nrho load), lub tshuab txhais lus yuav txav mus rau ntau qhov kev taw qhia (vim cua lossis nqes hav); Tus nqi tam sim no tau teeb tsa siab, lub nres nres tsis qhib thaum qhov thaiv tam sim no loj, tsis zoo rau lub cev muaj zog. Nws yuav tsum raug sau tseg tshwj xeeb tias qhov tam sim no tseem muaj kev taw qhia: rau kev nqa lub tshuab, cov kev taw qhia ntawm qhov tam sim no yog ib txwm zoo (lifting direction), rau kev txhais mechanism thiab kev sib hloov mechanism, cov kev taw qhia ntawm qhov tam sim no yuav tsum yog tib yam li. txoj kev taw qhia.
