Tsav chains yog siv dav hauv cov cuab yeej siv tshuab vim lawv qhov kev sib kis tau zoo, cov qauv yooj yim, thiab kev ua haujlwm txhim khu kev qha. Tsis zoo li txoj siv sia siv, uas tso siab rau kev sib txhuam, tsav cov saw hlau xa hluav taws xob los ntawm kev sib txuas ntawm cov saw nrog sprockets; qhov no tshem tawm kev swb, ua kom muaj qhov sib kis tau zoo, thiab ua rau lawv haum rau cov ntawv thov kom muaj zog sib kis tau zoo thiab muaj peev xwm los tuav cov khoom hnyav. Tsis tas li ntawd, tsav chains muaj ntau yam zoo, raws li lawv tuaj yeem xa hluav taws xob hla qhov chaw loj heev.
Nrog rau lawv cov load siab -cov kabmob muaj peev xwm- muaj peev xwm tiv taus lub zog tensile tseem ceeb thiab kev cuam tshuam cov loads- tsav chains feem ntau yog siv rau hauv kev tsim kho thiab kev ua liaj ua teb machinery, conveying systems, maus taus, thiab tsheb kauj vab. Vim tias cov saw hlau yog tsim los ntawm ntau qhov sib txuas, nws muaj qhov hloov tau yooj yim uas tso cai rau nws hloov mus rau qhov chaw ua haujlwm nyuaj. Nrog rau lubrication kom raug thiab tensioning txij nkawm thaum lub sijhawm ua haujlwm ntev -, lub kaw lus tswj kev ua haujlwm zoo thiab muaj lub neej ua haujlwm ntev.
