Chokwezera trolley chimayenda motalika kwa girder ndikukweza katunduyo pogwiritsa ntchito mbedza yomwe imamangiriridwa kumtunda. Ma cranes a Double-girder semi-gantry ndi abwino kunyamula katundu wokulirapo ndipo amatha kusinthidwa ndi zina zowonjezera monga magetsi, zida zochenjeza ndi machitidwe odana ndi kugunda.
Kupanga:Ma cranes a Semi gantryangagwiritsidwe ntchito popanga. Amapereka njira yosinthika komanso yotsika mtengo yonyamula ndikunyamula makina akulu ndi zidain fakitale. Ndiwoyeneranso kusuntha magawo, zinthu zomalizidwa komanso zopangira panthawi yonse yopanga.
Malo osungiramo katundu: Ma crane a mwendo umodzi ndi chisankho chodziwika bwino m'malo osungiramo zinthu omwe amafunikira kutsitsa ndikutsitsa katundu. Amatha kugwira ntchito m'malo otsekedwa ndipo amatha kunyamula katundu wolemetsa. Ndizoyenera kusuntha ma pallets, ma crate ndi zotengera kuchokera pamagalimoto kupita kumalo osungira.
