Semi-gantry Crane: a "boundary breaker" of workshop space
Between the steel columns of the workshop, a bright yellow semi-gantry crane breaks the shackles of the factory layout with its "single-sided legs clinging to the columns, and the main beam cantilevering across the obstacles" - turning the columns from "spatial barriers" into "hoisting fulcrums", and building an "air corridor" for efficient transportation in the gap between the equipment area and the material area.

Technical Parameters:
| Lifting Capacity | 5~20 tons (mainstream 10t) |
| Span | 7.5~25m (12~20m recommended) |
| Cantilever Length | 5~15m (customized ≤18m) |
| Lifting Height | 4~12m (clearance ≥3m) |
| Hoisting speed | 8~16m/min (dual-speed type 16/2m/min) |
Breaking the spatial barrier: Transforming columns into "hoisting springboards"
✅ Ingenious single-sided outrigger design: One side runs along the track against the column, while the other cantilevers out 5-15 meters. This transforms the "gray area" outside the column into a work area, saving 50% of track space and enabling renovations without disturbing the foundation.
✅ Flexible span adaptation: The 7.5-25m main beam span precisely matches the factory column spacing (with an error of ≤±50mm), creating a "custom track" for the workshop and adapting to diverse production lines from machining to new energy.
✅ Balanced lightweight and rigidity: The Q355B manganese steel box-type main beam is welded and inspected, resulting in a 25% reduction in deadweight compared to full-gantry cranes, yet capable of supporting loads of 5-20 tons. Static deflection at mid-span is ≤L/1000 (L = span), ensuring rock-solid stability for hoisting molds and steel.
All-purpose handling hub for the workshop
🔹 Equipment lifting: Lifting heavy machine tools and welding equipment, the boom lift reaches deep into the production line, replacing forklifts' roundabout lifting routes and increasing efficiency by 60%;
🔹 Material flow: Steel, molds, and semi-finished products shuttle between columns, and docking roller conveyors enable direct connection to the production line, eliminating ground-level congestion;
🔹 Customized breakthrough: Explosion-proof models tackle chemical workshops, while high-temperature-resistant models conquer heat treatment lines, becoming the workshop's "mobile joint" and adaptable to extreme scenarios.
