Zovala zolimba za chrome zokhala ndi zitsulo zimapangidwa kuti zizigwiritsa ntchito pogwira ntchito molemetsa, komwe mphamvu ndi nthawi yaukali ndizofunikira. Zomera zam'munsi, zimasankhidwa kukhala chitsulo chapamwamba kwambiri, zimasankhidwa chifukwa cha mphamvu zake, kulimba mtima, komanso kuthekera kupirira kupsinjika kwambiri. Ndodo yachitsulo imapereka njira yopukutira yoponyera kuti ipange malo osalala, omwe amathiridwa ndi wosanjikiza wa chromium kudzera mu elmomiproptatuti. Chikwangwanichi chikuwonjezera mphamvu ya ndodo, kupangitsa kuti ikhale yolimbana ndi kuvuta komanso kung'amba, ndikutipatsa chopinga chabwino chotsutsana ndi kututa ndi dzimbiri. Kuphatikiza apo, mawonekedwe osalala ndi olimba a chiwonetsero amachepetsa kukangana, kukonza zida ndi kukonza moyo wa ndodo yonse ndi zisindikizo zake mu hydraulic ndi ma pneraulic. Zipangizozi zimagwiritsidwa ntchito kwambiri pakugwiritsa ntchito mafakitale osiyanasiyana, kuphatikizapo mawotchi a hydraulic, ma viniki opanga mapangidwe, ndi zida zina zamakina zomwe zimafunikira molondola komanso kukhazikika.
