Endesha Pulley
Muhtasari
Kapi ya kichwa iko mahali ambapo conveyor hupakia, inayojulikana kama mwisho wa upakuaji wa conveyor ya ukanda.Kwa sababu inaendesha mfumo mzima, kwa kawaida inahitaji kanzu mbaya inayofunika uso wa nje ili kuongeza traction ya ukanda wake.
Pulley ya kichwa kawaida ina kipenyo kikubwa zaidi cha pulleys zote.Wakati mwingine, mfumo unaweza kuwa na kapi zaidi ya moja kama kapi ya kuendesha.Pulley ya mwisho ya kutokwa, kwa kawaida kipenyo kikubwa zaidi cha roller ya kuendesha gari, inaitwa pulley ya kichwa.
Hii iko kwenye mwisho wa upakiaji wa conveyor ya ukanda.Wakati mwingine huja na sura ya mrengo kusafisha ukanda kwa kuruhusu nyenzo kuanguka kando kwa sehemu za usaidizi.
Katika usanidi rahisi wa kisafirishaji wa ukanda, kapi ya mkia itawekwa kwenye reli ya kawaida iliyofungwa ili kuruhusu mkazo wa mikanda.Katika mifumo mingine ya kusambaza mikanda kama tutakavyoona, mvutano wa ukanda huachwa kwa roller nyingine inayoitwa roller ya kuchukua.
