A double girder semi-gantry crane combines features of an overhead crane and a gantry crane. One side travels on an elevated runway supported by the building or a dedicated structure, while the opposite side travels on an independent leg and ground-level runway. The arrangement can reduce structural constraints in selected facilities.
ACG double girder semi-gantry cranes combine a building-supported runway on one side with an independent gantry leg on the other for industrial lifting projects.
Final dimensions, component selection and operating parameters are defined from project data, duty requirements, site conditions and the agreed engineering scope.
| Capacity | Defined by project load and duty requirements |
|---|---|
| Span | Defined from runway and leg geometry |
| Lift height | Defined by process requirements |
| Hoisting system | Hoist or open winch according to project scope |
| Duty class | Selected from operating cycles and load spectrum |
| Runway interface | Coordinated with building and ground-side structure |
