Yiziphi izizathu zokukhala okungavamile komkhawulo womnyango?
1. Izinkinga zenqubo yokuklama nokukhiqiza, ingaphezulu lengalo yomkhawulo kanye nohlangothi lwe-roller esekela umsindo ongajwayelekile, i-hinge shaft yesicabha kanye ne-rotation shaft of the limit akuhambelani ngokujulile;
2. Vula noma uvale umnyango ngobudlova isikhathi eside, okuholela ekuguqulweni kwamandla, ukugoba nokulimala komkhawulo womnyango;
3. Ibangelwa ukuhlangana okungafanele;
4. Ukuguga komkhawulo womnyango noma ukuwisa umnyango ngesikhathi sokusetshenziswa;
5. Ubuso be-limiter ukuntuleka kokugcoba.
Inhloso yesinqamuli somnyango wukukhawulela izinga umnyango ongavulwa ngalo. Ngakolunye uhlangothi, ingakwazi ukukhawulela ukuvuleka okukhulu komnyango ukuze ivimbele ukuthi ingavuleki kakhulu, futhi ngakolunye uhlangothi, ingagcina umnyango uvulekile lapho kudingeka, njengalapho imoto ipakwe emgwaqeni noma lapho kunomoya ovamile, umnyango ngeke uvale ngokuzenzakalelayo.Kunezikhawulo ezimbili ezivamile zomnyango wezimoto, ziyi-torsion bar spring limiter kanye ne-pull bar limiter. Kusukela kuzindleko zokukhiqiza noma izindleko zokulungisa, i-pull bar limiter ingcono kune-torsion bar spring limiter, ngokwemvelo evamile kakhulu, kodwa umphumela womkhawulo we-pull bar limiter awuyona i-torsion bar spring limiter kalula nje, ukusebenza kuqondile kakhulu, ezinye izimoto zizwa ukuthi umkhawulo usobala futhi ezinye izimoto azibonakali.
