A kireni yolimbana ndi mpweyandi chipangizo chogwiritsira ntchito mphamvu ya pneumatic chomwe chimagwiritsa ntchito mphamvu yokoka ya chinthu cholemera ndi kupanikizika mu silinda kuti chikhale cholinganiza bwino kukweza kapena kutsitsa chinthu cholemera. Kawirikawiri crane yolinganiza ya pneumatic imakhala ndi mfundo ziwiri zolinganiza, zomwe ndi kulinganiza katundu wolemera komanso kusalinganiza katundu. Kulinganiza katundu wolemera ndi mkhalidwe wolinganiza bwino pamene pali katundu wolemera pa crane yolinganiza bwino, ndipo kusalinganiza katundu ndi mkhalidwe wolinganiza bwino pamene palibe katundu pa crane yolinganiza bwino. Mosasamala kanthu za mkhalidwe wolinganiza bwino, gripper imakhala yopumula, pamene mphamvu yochepa kwambiri yakunja ikufunika kukweza kapena kuchepetsa kulemera kapena gripper. Pogwiritsa ntchito mfundo iyi ya crane yolinganiza ya pneumatic, imatha kukonza magwiridwe antchito ndikuchepetsa mphamvu ya antchito. Kuphatikiza apo, crane yolinganiza ya pneumatic ili ndi kapangidwe kosavuta, zigawo zochepa, mtengo wotsika ndipo ingagwiritsidwe ntchito m'mikhalidwe yovuta yogwirira ntchito.
Gawo lalikulu la pneumatickireni yolinganizandi valavu yothamanga kwambiri, mpweya woipa wambiri, valavu yochepetsera kuthamanga kwa mpweya yolondola kwambiri, valavu yochepetsera kuthamanga iyi ikugwirizana mwachindunji ndi kulondola kwa malo a kulemera, kukula kwa mphamvu yakunja yofunikira kuti isunthe kulemera, ndi liwiro losuntha kulemera.
Ma valve awiri ochepetsera kupanikizika kwa oyendetsa amatengedwa kuchokera ku mzere waukulu, womwe umagwiritsidwa ntchito ngati ma valve oyendetsera kuti katundu wolemera akhale bwino komanso kuti katundu asayende bwino. Mpweya woyendetsa umadutsa mu valavu yobwezera kumbuyo ya njira ziwiri, yomwe imagwiritsidwa ntchito kusinthana pakati pa kulemera kwa katundu ndi kusayenda bwino kwa katundu. Pambuyo pa valavu yobwezera kumbuyo, mpweya woyendetsa umadutsa mu valavu yochepetsera kupanikizika yolamulidwa ndi mpweya, ndipo kuthamanga kwa valavu yochepetsera kupanikizika yolamulidwa ndi mpweya kumakhala kofanana ndi kuthamanga kwa oyendetsa. Mpweya wochokera ku mzere waukulu umachepetsedwa ndi valavu yochepetsera kupanikizika yolamulidwa ndi mpweya kenako umadutsa ku silinda, yomwe imadzazidwa ndi mpweya ndipo pisitoni imakwera, motero imakoka kulemera.
Pamene kulemera kwakwezedwa ndi kupumula, zikutanthauza kuti kulemera kwa katundu wolemera kwafika, ndiye kuti mphamvu yochepa yakunja yokha ndiyo imafunika kuti iswe mphamvuyi, ndipo ikhoza kukwezedwa mosavuta kapena kuchepetsedwa. Tengani kukoka kulemera kuti muswe mphamvuyi mwachitsanzo, mukagwiritsa ntchito mphamvu yakunja kuti mukoke pansi, pisitoni yomwe ili mu silinda imatsika pansi, kenako kupanikizika mu silinda kumakwera ndikupitirira mphamvu yomwe yayikidwa (kupanikizika kumeneku ndi kupsinjika komwe kuli muyeso), kupanikizika kochulukirapo kudzatulutsidwa kuchokera ku doko lotulutsa la valavu yochepetsera kupanikizika yolamulidwa ndi mpweya. Zotsatira za njira yotereyi ndi izi: pisitoni (kulemera) imatsika pamalo enaake ndipo imakhala yosasuntha, ndipo kupanikizika mu silinda kumabwerera ku kuthamanga komwe kunalipo kale. Mosiyana ndi zimenezi, kukweza kulemera mmwamba kuti muswe mphamvu ya kupanikizika mu silinda ndi chinthu chomwecho, kupatula kuti mpweya umapita mozungulira (kuchokera ku silinda kupita ku doko lotulutsa utsi la valavu yochepetsera kupanikizika yolamulidwa ndi mpweya) ndipo inayo ili munjira yabwino (valavu yochepetsera kupanikizika yolamulidwa ndi mpweya imapita mu silinda).
