Ingabe iketango eliphindwe kabili le-hand chain hoist lingashintshwa libe yiketango elilodwa?

I-hand chain hoistzisetshenziselwa ukuqedela imisebenzi yokuphakamisa ngokusebenza ngesandla. Zisetshenziswa kabanzi embonini, kwezokwakha, kwezokuthutha nakweminye imikhakha. Kodwa-ke, sizohlangabezana nezimo ezithile lapho sizisebenzisa, ngakho-ke iketango eliphindwe kabili lama-hand chain hoist lingashintshwa libe yiketango elilodwa. ? Ake sikwethule ngokuningiliziwe ngezansi:

Masiqale siqonde umehluko phakathi kwe-double chain kanye ne-single chain hand chain. Amaketango amabili okuphakamisa isandla akhiwe ngamaketango amabili okuphakamisa, angathuthukisa umthamo wokuthwala umthwalo nokuzinza. Idizayini ye-double chain yenza i-hoist yeketango iqine futhi ithembeke ngesikhathi sokusetshenziswa. I-single-chain hand chain hoist yenziwe iketango eliphakamisayo futhi inamandla aphansi okuthwala umthwalo, ngakho ifanelekela umsebenzi othile wokuphakamisa ukukhanya. Abanye abantu bangase babuze ukuthi i-double chain hand chain hoist ingashintshwa ibe i-hoist yeketango lesandla elilodwa? Ukukhuluma ngokuqinile, lokhu akuvunyelwe. Ukushintsha okokusebenza ngaphandle kwemvume kungase kudale izingozi.

Ngaphansi kwezimo ezijwayelekile, ama-hoists angama-3-ton hand chain kanye nama-5-ton hand chain hoist anamaketango aphindwe kabili. Amandla okuthwala ama-hand chain hoist amathoni ahlukene nawo ahlukile. Uma i-hoist yeketango lesandla ishintshiwe, iketango elilodwa lokuphakamisa liyancishiswa, ngakho-ke umthamo wokuthwala nawo Wehlile, futhi ukwakheka kwe-hoist yeketango lesandla elingunxantathu ukuthi ihhuku engaphezulu nehhuku engezansi zisemgqeni ofanayo. Ngemva kokuguqulwa okungalungile, imigqa emi-2 yokuphakamisa amaketanga e-hand chain hoist yashintshwa yaba umugqa ongu-1, futhi ihuku engenhla nehhuku engezansi kwakusemgqeni ofanayo. Izingwegwe azikho emgqeni. Kulokhu, ukuphakamisa izimpahla kuzoba yingozi futhi izingozi zingase zenzeke.

Ngakho-ke, i-doublechain hand chain hoist ayikwazi ukushintshwa ibe i-hoist yeketango lesandla elilodwa. Umkhiqizi ophakamisa i-hoist ukukhumbuza ukuthi uma ukhetha i-hand chain hoist, ungakhetha umkhiqizo ofanele we-hand chain hoist ngokusekelwe esidingweni sangempela nesisindo sempahla.
