gantry crane (A gantry crane is a crane built atop a gantry, which is a structure used to straddle an object or workspace. They can range from enormous "full" gantry cranes, capable of lifting some of the heaviest loads in the world, to small shop cranes, used for tasks such as lifting automobile engines out of vehicles. They are also called portal cranes, the "portal" being the empty space straddled by the gantry.: Козловы́е кра́ны — краны мостового типа, мост (пролётные строения) которых установлен на опоры, перемещающиеся по рельсам, установленным на бетонные фундаменты. Внешне похожи на козлы, отсюда и название.  wikipedia.org) |
