Dhul-xumada farta (farta pneumatic ama farta pnewsatic ama claw) ayaa garan kara hawlo kala duwan oo kala duwan, waa qaybta ugu muhiimsan ee maacuunta casriga ah, oo badanaa lagu xalliyo shaqada shaqada ee warshadaha baakadaha, qalabka warshadaha cuntada.
I. Ujeedada dhululubada farta
Faraha faraha ee pneumatic, oo sidoo kale loo yaqaan cufnaanta pneumatic ama ciriiriga hawada, waxaa ku shaqeeya hawo isku buuqsan waxaana loo isticmaalaa in lagu qanco ama qabsado shaqada shaqada. Waxay asal ahaan ka soo jeedday Japan, waxaa si weyn u isticmaalay shirkadaha maxalliga ah.
Sida ku xusan qaabka sida caadiga ah waxaa loo qaybin karaa farta yar ee poshin iyo farta nooca nooca ah. Dhex-dhexaadimaha Dheeraadka ah ayaa loo qaybiyaa 16mm, 20mm, 25mm, 32mm iyo 40mm. Hawsha ugu weyn ayaa ah in la beddelo shaqada gacanta aadanaha, si wax ku ool ah u hagaajin kara waxtarka wax soo saarka iyo badbaadada shaqada. Taxanaha farta ee 'SMC' ee PNC waa mid ka mid ah aaladda ugu badan ee kululaata ee kululaata ee ku jirta dhulka warshadaha.

II. Waxyaabaha xulashada ah ee fardaha dhululubo fara badan (claw)
1) Xulo isbarbar dhig furan - noocee (MHz2 {{5 {5 {5-2D, MHCRUM-16D, MHC2-20d) Marka loo eego cabirka, qaabka iyo ujeeddada shaqada;
2) Xulo taxanaha dhululubo farta (ciriiriga hawada) iyadoo loo eegayo cabirka, qaabka, wacyigelinta, isticmaal jawiga iyo adeegsiga ujeeddada shaqada;
3) Xulo cabirka ciriiriga hawada iyadoo loo eegayo xoogga xajisiinta hawada, masaafada meesha lagu xirayo, qaddarka wacyigelinta iyo istaroogga;
4) Xulashooyin badan ayaa loo samayn karaa iyadoo loo eegayo shuruudaha.
III. Astaamaha dhululubada farta (ciriiriga hawada)
1) Qaab dhismeedka farta dhululubo waa labanlaab {{1} Fasniin ah, oo garan karta laba {{2-2} inuu si toos ah ula qabsado, si otomaatig ah, oo leh saxsanaanta ku celcelinta sare;
2) daqiiqad isdaba joog ah oo joogto ah;
3) Groogaroogga labada dhinac ee dhululubada ee wareejinta magnetic;
4) Rakibaadda kala duwan iyo habab xidhiidh ah
Iv. Mabda 'shaqo oo dhululubo farta ah (cluw cluw)
Jaantus mabdana'da shaqada ee dhululubada farta ayaa lagu muujiyey hoosta
Markaad dekedda iyo dekeda dekedda ku taal, dhul-daareed Jooji Block 6 si loo xaddido faafka faafinta farta, oo ku yaal meel ku yaal PIN 7 si loo hubiyo isugeynta wanaagsan ee tareenka toosan ee hagida toosan.
