Chain lub zog yog ib qho tseem ceeb ntawm cov saw hlau tshwj xeeb, vim nws txiav txim siab qhov siab tshaj plaws ntawm cov saw hlau tuaj yeem tiv taus. Chain lub zog yog feem ntau txiav txim siab los ntawm kev ntsuas tensile thiab qhia txog kev tawg. Thaum xaiv cov saw hlau, nws yog ib qho tseem ceeb los txiav txim siab qhov tsim nyog lub zog raws li lub elevator qhov ntsuas load thiab qhov chaw ua haujlwm kom muaj kev nyab xeeb thiab txhim khu kev qha.
Ob peb lwm yam tsis hais txog lub thoob of elevator chains kuj yuav tsum tau xav txog, xws li saw pitch, sprocket hniav suav, thiab saw pre- nro. Cov saw pitch- txhais tau tias qhov kev ncua deb ntawm cov kab nruab nrab ntawm ob tus pins uas nyob ib sab- tswj hwm kev sib koom ua ke ntawm cov saw hlau thiab sprocket. Tus naj npawb ntawm cov hniav sprocket, lub sijhawm no, cuam tshuam cov saw hlau ua haujlwm ceev thiab ruaj khov. Chain pre- nro yog siv los xyuas kom meej tias cov saw hlau tswj kom muaj qhov sib npaug ntawm qhov nro thaum ua haujlwm, yog li tiv thaiv cov teeb meem xws li slackening lossis hniav hla.
Thaum xaiv cov chains rau thoob elevator, nws yog ib qho tsim nyog yuav tsum ua raws li cov qauv kev lag luam uas cuam tshuam, suav nrog lub teb chaws thiab kev lag luam - cov kev cai tshwj xeeb. Tsis tas li ntawd, cov txheej txheem xaiv yuav tsum tau ua raws li cov kev ua haujlwm tshwj xeeb thiab cov kev xav tau ntawm of the elevator- xws li nqa qhov siab, nqa ceev, thiab cov yam ntxwv ntawm cov khoom siv. Thaum xaiv cov txheej txheem, nws raug nquahu kom sab laj nrog cov kws tshaj lij saw hlau lossis cov neeg muag khoom kom tau txais cov lus pom zoo thiab kev txhawb nqa.
