Drum pulleys akhala akugwiritsidwa ntchito kwa zaka mazana ambiri ndipo akupitirizabe kugwiritsidwa ntchito muzinthu zambiri zamasiku ano.M'makampani akuluakulu, ntchito zawo zimakhala zazikulu kwambiri.Mainjiniya amapanga makina a pulley poganizira kwambiri chilengedwe.Mwachitsanzo, mafakitale okhala ndi fumbi ndi zinyalala pafupipafupi angafunike chopukutira chodzitchinjiriza kapena ma bere apadera ndi zisindikizo kuti atetezedwe ku zinthu zakunja.Malo okhala ndi mvula komanso owuma amafunikira ma liner enieni, ndipo kugwiritsa ntchito zinthu zowononga kwambiri kumafunikira zida zolimba kuti zithandizire ntchitoyi.

Mu ntchito zotumizira lamba, gawo la pulley ndi katatu.

1) kuthandizira lamba pakusintha kwamayendedwe ndi kapangidwe ka conveyor.

2) kutumiza mphamvu zoyendetsa ku lamba, ndi

3) kutsogolera kapena kuphunzitsa lamba.

Pulley yoyendetsa imatumiza mphamvu yoyendetsera lamba ndipo imatha kupezeka pamutu kapena kumapeto kwa chotengera, mu unyolo wobwerera, kapena kumapeto kwa chotengera.

Pulley ya khushoni ili pafupi ndi pulley yoyendetsa galimoto kuti apereke ma arcs okhudzana kwambiri pakati pa lamba ndi pulley kuti azitha kuyendetsa bwino pamene mukuyendetsa lamba.

Pulley yamutu ili kumapeto kwa chotengeracho ndipo muzotengera zosavuta nthawi zambiri ndi pulley yoyendetsa.

Pulley ya mchira ili pamapeto otseguliraidler conveyorndipo m'zotengera zosavuta nthawi zambiri mumakhala pulley yokhotakhota.

Kufotokozera

Ming'oma yolemera kwambiri yopangidwa ndi ogulitsa a GCS Conveyor amakwaniritsa kapena kupitilira miyezo ya Conveyor Equipment Manufacturers Association (CEMA).Zida zotumizira mphamvuzi zimakhala ndi mapangidwe osinthika a pulley.Ma ng'oma athu amatipatsa moyo wautali, wosasokonezeka.
