Qalabka laba-jibbaaran ee loo yaqaan 'double pitch conveyor' badanaa waa kuwo ku habboon in lagu keydiyo booska waxayna leeyihiin cimri dheer marka loo eego qalabka caadiga ah ee loo yaqaan 'sprocket'. Ku habboon silsiladda dheer ee loo yaqaan 'procket', qalabka laba-jibbaaran ee loo yaqaan 'double pitch sprocket' waxay leeyihiin ilko ka badan qalabka caadiga ah ee isku dhexroorka wareegga ah waxayna si siman ugu qaybiyaan ilkaha oo dhan. Haddii silsiladdaada gudbiyaha ay la jaanqaadi karto, qalabka laba-jibbaaran ee loo yaqaan 'double pitch sprockets' ayaa hubaal ah inay mudan yihiin in la tixgeliyo.
Biyo-xidheennada silsiladaha laba-laaban ee laba-laaban ayaa laga heli karaa naqshad hal ama laba-ilkood ah. Biyo-xidheennada hal-ilkood ah ee silsiladaha laba-laaban ee laba-laaban waxay leeyihiin hab-dhaqan la mid ah biyo-xidheennada caadiga ah ee silsiladaha duuban sida waafaqsan DIN 8187 (ISO 606). Iyada oo ay ugu wacan tahay silsiladda ballaaran ee silsiladaha duuban ee laba-laaban, waxaa suurtagal ah in la kordhiyo cimri dhererka iyadoo wax laga beddelayo ilkaha.
Noocyada caadiga ah ee duubista ayaa ah isku dhexroorka iyo ballaca dibadda oo la mid ah kan hal-godka ah oo keliya iyadoo leh qaab ilko oo kala duwan si loogu oggolaado in si habboon loogu fariisto silsiladda. Xataa marka la tiriyo ilkaha, daloolladani waxay la falgalaan oo keliya silsiladda ilig kasta oo kale sababtoo ah waxaa jira laba ilig halkii cod. Tirooyinka ilig ee aan caadiga ahayn, ilig kasta oo la bixiyo waxaa lagu sameeyaa oo keliya wareeg kasta oo kale taasoo dabcan kordhisa cimriga daloolka.
