Kapangidwe Koyambira
Kireni ya pillar jib, yomwe imadziwikanso kuti jib crane yokhala ndi mipiringidzo, ndi chipangizo chonyamulira zinthu chomwe chimagwiritsidwa ntchito m'mafakitale osiyanasiyana pokonza zinthu. Zigawo zake zazikulu ndi izi:
1. Chipilala (Kolamu): Kapangidwe kochirikiza koyima komwe kamamangirira kreni pansi. Nthawi zambiri imapangidwa ndi chitsulo ndipo imapangidwa kuti inyamule katundu wonse wa kreni ndi zinthu zonyamulidwa.
2. Dzanja la Jib: Mtanda wopingasa womwe umachokera ku mzati. Umatha kuzungulira mzati, kupereka malo ogwirira ntchito ambiri. Dzanja nthawi zambiri limakhala ndi trolley kapena chokwezera chomwe chimayenda m'litali mwake kuti chiyike katundu molondola.
3. Trolley/Hoist: Yoyikidwa pa mkono wa jib, trolley imayenda molunjika motsatira mkono, pomwe choyimitsa, cholumikizidwa ku trolley, chimakweza ndikuchepetsa katundu. Choyimitsacho chingakhale chamagetsi kapena chamanja, kutengera momwe chikugwiritsidwira ntchito.
4. Njira Yozungulira: Imalola mkono wa jib kuzungulira chipilala. Izi zitha kuchitika ndi manja kapena motengera, ndipo kuchuluka kwa kuzungulira kumasiyana kuyambira madigiri ochepa mpaka 360° yonse, kutengera kapangidwe kake.
5. Maziko: Maziko a crane, omwe amatsimikizira kukhazikika. Amamangiriridwa bwino pansi, nthawi zambiri pogwiritsa ntchito maziko a konkriti.
Mfundo Yogwirira Ntchito
Ntchito yakireni ya pillar jibZimaphatikizapo mayendedwe angapo ogwirizana kuti anyamule, kunyamula, ndi kuyika zinthu bwino. Njirayi ingagawidwe m'magawo otsatirawa:
1. Kukweza: Chokweza chimakweza katundu. Woyendetsa amalamulira chokweza, chomwe chingachitike pogwiritsa ntchito chowongolera, chowongolera kutali, kapena kugwiritsa ntchito pamanja. Njira yokwezera chokweza nthawi zambiri imakhala ndi mota, gearbox, ng'oma, ndi chingwe cha waya kapena unyolo.
2. Kuyenda Molunjika: Trolley, yomwe imanyamula chokweza, imayenda motsatira mkono wa jib. Kuyenda kumeneku kumalola kuti katunduyo aikidwe kulikonse motsatira kutalika kwa mkono. Trolley nthawi zambiri imayendetsedwa ndi mota kapena kukankhidwa ndi manja.
3. Kuzungulira: Dzanja la jib limazungulira chipilala, zomwe zimathandiza kuti crane iphimbe malo ozungulira. Kuzungulirako kungakhale kwamanja kapena koyendetsedwa ndi mota yamagetsi. Mlingo wa kuzungulira kumadalira kapangidwe ka crane ndi malo oikira.
4. Kutsitsa: Katundu akafika pamalo omwe mukufuna, chokwezera chimachitsitsa pansi kapena pamwamba. Woyendetsayo amawongolera mosamala kutsika kuti atsimikizire malo ake komanso chitetezo.
Ma pillar jib cranes amayamikiridwa kwambiri chifukwa cha kusinthasintha kwawo, kugwiritsa ntchito mosavuta, komanso kugwira bwino ntchito zipangizo m'malo obisika. Amagwiritsidwa ntchito kwambiri m'ma workshop, m'nyumba zosungiramo katundu, ndi m'mizere yopangira zinthu komwe malo ndi kuyenda ndizofunikira kwambiri.
