Feem ntau cov saw hlau yog ib qho txuas hlau lossis lub nplhaib, uas feem ntau yog siv rau kev sib kis thiab kev rub. Cov khoom zoo li saw hlau siv los thaiv kev hla kev (xws li ntawm qhov nkag ntawm txoj kev, dej lossis chaw nres nkoj), cov saw hlau siv rau kev sib kis.

1. Cov saw hlau muaj plaub series: cov saw hlau kis tau tus mob; cov saw hlau conveyor; cov saw hlau rub; cov saw hlau tshwj xeeb.

2. Ib cov txuas lossis cov voj voog uas feem ntau ua los ntawm hlau: cov khoom zoo li saw hlau siv los thaiv kev hla kev (xws li ntawm qhov nkag ntawm txoj kev, dej lossis chaw nres nkoj); ib txoj saw hlau siv rau kev sib kis tshuab.

3. Cov saw hlau muaj peev xwm muab faib ua cov saw hlau luv luv; cov saw hlau luv luv; cov saw hlau nkhaus rau kev sib kis hnyav; cov saw hlau rau cov tshuab cement thiab cov saw hlau phaj; cov saw hlau muaj zog heev.

Cov qauv ntawm cov saw hlau kis tau yog tsim los ntawm cov txuas sab hauv thiab cov txuas sab nraud. Nws muaj tsib qhov me me: phaj saw hlau sab hauv, phaj saw hlau sab nraud, tus pin, tes tsho thiab lub log. Qhov zoo ntawm cov saw hlau nyob ntawm tus pin thiab tes tsho.

Hauv kev sib kis ntawm cov cuab yeej siv tshuab, cov khoom siv sib kis feem ntau suav nrog pulleys, iav, iav kab, racks thiab pinions, thiab cov ntsia hlau. Los ntawm cov khoom sib kis no, lub zog thiab lub actuator, lossis kev sib txuas ntawm ob lub actuators, hu ua kev sib txuas kis. Ib qho series ntawm cov khoom sib txuas sib law liag uas tsim kev sib txuas kis hu ua txoj saw hlau kis.

Cov saw hlau kis tau feem ntau muaj ob hom kev sib kis: ib hom yog lub tshuab kis tau nrog qhov sib piv sib kis thiab kev taw qhia kis, xws li qhov sib piv sib txawv ntawm cov iav sib txuas, cov kab mob turbine sib txuas, thiab lwm yam, hu ua lub tshuab kis tau sib piv sib txawv; lwm hom yog raws li cov kev xav tau ua tiav. Lub tshuab kis tau uas tuaj yeem hloov qhov sib piv sib kis thiab kev taw qhia kis, xws li lub tshuab hloov iav kis, lub tshuab kis tau sib tsoo, thiab lwm yam, hu ua lub tshuab hloov pauv.
