Zvikamu uye Kushanda Nheyo yeRimwe Girder Pamusoro peCrane:
Working Principle:
Nheyo yekushanda yegirder pamusoro pecrane inosanganisira matanho anotevera:
Izvo zvakakosha kuti uzive kuti iyo chaiyo zvikamu uye misimboti yekushanda inogona kusiyana zvichienderana nekugadzira uye mugadziri weiyo imwe girder pamusoro pecrane.
Mushure mekutenga imwe girder pamusoro pecrane, zvakakosha kufunga mushure mekutengesa sevhisi uye kugadzirisa kuti ive nechokwadi chekuita kwayo kwakakwana, hupenyu hurefu, uye chengetedzo. Heano mamwe akakosha ezve mushure mekutengesa sevhisi uye kugadzirisa:
