Cov tshuab hauv kev tsim cov thawv hlau plaub fab nrog lub kaum sab xis, yooj yim, raug, ceev, hom khoom hydraulic, pneumatic thiab pedal, kho mob, rooj tog hlau, rooj tog hauv chaw ua haujlwm hlau, chav ua noj, kho vajtse thiab lwm yam lag luam yog qhov siv tau zoo heev.

Cov khoom siv no feem ntau yog siv rau kev txiav cov hlau thiab cov khoom tsis yog hlau. Siv lub zog hydraulic ua lub zog, kev txav mus los du, lub zog, ua rau cov khoom siv tuab tuaj yeem ua tiav. Cov ntaub ntawv hniav nrog cov hlau alloy siab (Cr12MoV), qhov nyuaj quenching ntawm HRC 58/62, ua tiav qhov chaw, ua rau lub cuab yeej siv tau ntev thiab zoo ntawm kev ua tiav. Lub tshuab no muaj kev ceev ceev, zoo, kev tswj hwm txhim khu kev qha, kev ua haujlwm yooj yim, kev hloov kho, kev saib xyuas yooj yim, lub neej ua haujlwm ntev, thiab lwm yam. Cov khoom siv nyiam rau cov tuam txhab ua hlau ntawv.
