Semi-gantry Cranes: a "space disruptor" for factories and a smart lifting solution for semi-dependent buildings
When factory expansion encounters a "space bottleneck" - there is no place to put new equipment, the old factory building needs to be expanded, and the full-gantry crane is too expensive and takes up too much space... Semi-gantry cranes (semi-gantry cranes) emerge like "industrial geckos": one side clings to the building's load-bearing structure, and the other side stands alone, turning the "gap between the building and the open space" into an efficient lifting area, redefining the rules of industrial space utilization.

Technical Parameters:
| Lifting Capacity | 1~50 tons (regular), customizable up to 80 tons |
| Span | Building side: 5~20 meters; Column side: 6~30 meters |
| Lifting Height | Building side: ≤ net height of factory building - 1 meter (e.g., if the factory building is 9 meters high, the lifting height is 8 meters); Column side: 8-25 meters |
| Work Duty | A3 (light grade, such as machining) ~ A6 (heavy grade, such as steel mills) |
Breakthrough Scenario: Specially Designed to Address "Awkward Space"
The core value of semi-gantry cranes lies in their ability to "leverage the building's inherent strength," precisely addressing three key pain points:
Old Factory Renovation: When expanding an old factory building, existing columns/corbels can be utilized for support, eliminating the need for a new full-gantry crane track foundation and saving 30% in civil engineering costs.
Cross-Zone Operation: At the interface between a workshop and an open-air storage yard, a semi-gantry crane can be positioned "half inside the workshop, half outside," enabling seamless transfer of goods between indoor and outdoor spaces (e.g., transporting steel components directly from the workshop to the storage yard).
Height Utilization: The lifting height on the building side can exceed the factory building's limitations (e.g., 8 meters inside the building, 12 meters on the column side), making it suitable for lifting multi-story racks or extra-high equipment.
