Cov log tsheb hloov pauv hauv kev ua lag luam tau muab faib ua ob hom fais fab loj: pneumatic thiab hydraulic, nrog rau qhov sib txawv ntawm cov tub ntxhais sib txawv los ntawm lub zog xa mus nruab nrab Pneumatic qauv cia siab rau compressed cua los tsav lub tog raj kheej. Txij li thaum huab cua yog compressible, cov lus teb yog ceev thiab lub teeb, lub cev yog yooj yim thiab yooj yim los tswj, thiab nws yog rau lub teeb log tsheb xws li cov neeg nrog caij tsheb thiab maus taus. Nws yog qhov kev xaiv tseem ceeb rau cov khw muag khoom me me thiab nruab nrab ntawm kev kho sai vim nws cov nqi qis dua thiab hloov tau yooj yim pib ua haujlwm.

Hydraulic qauv xa hluav taws xob siv hydraulic roj. Txij li cov kua yog incompressible, cov zis torque yog ruaj khov nrog lub zog tawg. Lub log tsheb nias thiab tev lub zog yog uniform rebounding. Nws yog qhov nyuaj dua thaum cuam tshuam nrog cov tsheb thauj khoom hnyav, cov log tsheb tuab-walled engineering, thiab cov log tsheb nyuaj. Nws tuav lub zog sib xws thaum lub sijhawm ua haujlwm tsis tu ncua thiab tsis tshua muaj peev xwm khawb cov rims.

Kev sib txawv yooj yim: Xaiv pneumatic rau kev kho tsheb me me txhua hnub; xaiv hydraulic rau cov tsheb loj, hloov cov log tsheb tuab, thiab cov khoom siv hnyav hnyav. Kev nkag siab txog cov yam ntxwv ntawm ob lub tshuab hluav taws xob no tso cai rau koj xaiv txoj cai "tus neeg muaj zog" raws li koj lub khw kev lag luam, txhim kho lub log tsheb hloov kev ua haujlwm thiab txo cov log tsheb.
