Ntchito zomanga zimafunikira zida zosiyanasiyana kuti zitsimikizire kuti ntchito zofunikira zimaperekedwa moyenera komanso mwachangu.Mu positiyi, tikambirana kusiyana pakati pa hoist ndi lift pomanga.
Zida zonyamula ndi kukweza nthawi zambiri zimawonedwa ngati zofananira pomwe zimayendetsedwa m'njira zosiyanasiyana ndipo zitha kugwiritsidwa ntchito pazinthu zina.Momwemonso, mitundu ina ya zida zomangira imakwaniritsa zofunikira zinazake.
M'mawu osavuta, chokweza ndi chipangizo chomangira chomwe nthawi zambiri chimagwiritsa ntchito makina a pulley kukweza zinthu m'mwamba pomwe chokweza chomanga chimaphatikizapo nsanja yamlengalenga yomwe imasungidwa ndi mawonekedwe enaake owonjezera ndikuyika pagalimoto.
Zokweza ndi zokwezera zonse zimagwiritsidwa ntchito pofuna kunyamula katundu wolemetsa womwe umaphatikizapo ogwira ntchito ndi zipangizo kuchokera pansi kupita pansi pa nyumba iliyonse.Kuphatikiza apo, ma hoist amagwiritsidwa ntchito nthawi zambiri ngati mafakitale ndipo amaloledwa kupezeka ndi anthu pomwe zokweza zina zimayikidwa kwamuyaya mnyumba zansanjika zambiri.
Chokwezera chomangira chimaonedwa kuti ndichofunika kwambiri pomanga nyumba zapamwamba zomwe sizimangothamangitsa kuyenda kwa katundu pakati pa pansi ndi pansi komanso kumateteza chitetezo chamayendedwe.
Imamangidwa ndikukhazikitsidwa pamalowo mothandizidwa ndi crane tower.Ikhoza kuthetsedwa ndi kusamutsidwa mosavuta kuchokera kumalo amodzi kupita ku ena.
Ma hoists amagwiritsa ntchito zingwe zamawaya kapena maunyolo omangika mozungulira mbiya kapena ng'oma kuti agwiritse ntchito makina a pulley omwe amatha kuyendetsedwa pamanja kapena pamagetsi.Mitundu ina ya ma hoist imatha kuyendetsedwa kudzera mu ma hydraulics pomwe ina imayendetsedwa ndi pneumatic.
Kutengera ndi cholinga ndi kagwiritsidwe ntchito, ma hoists nthawi zambiri amagawidwa ngati zokweza zakuthupi ndi zokweza antchito.
Zokwezera zida zidapangidwa kuti zizitha kunyamula zida zomangira, zida, ndi zinthu zomwe zimakhala zolemetsa kwambiri kuti zitha kunyamulidwa pamanja kuchokera pansi ndi madesiki osiyanasiyana.Kumbali ina, zokwezera antchito zapangidwa kuti zinyamule ndikusintha antchito omanga m'nyumbamo.
Chokwezera ogwira ntchito kapena chokwera chokwera anthu nthawi zambiri chimayendetsedwa mkati mwa khola ndikugwiritsa ntchito zida zotetezera zomwe zimalepheretsa kugwa kwaulere kapena zovuta zilizonse zomwe zingawononge anthu omwe ali mkatimo.
Pogwiritsa ntchito zida zokwezera, ndikofunikira kuganizira cholinga choyambirira cha hoist.Zopangira zida zina zimangogwiritsidwa ntchito pomanga ndi zida pomwe zina zimatha kutengera zida ndi antchito.Komabe, njira zogwiritsira ntchito izi zimafuna kutsata mosamala malamulo achitetezo ndi malamulo omwe amawongolera magwiridwe antchito a hoist.
