Semi-gantry Cranes: breaking through on one side and activating new potential in factory space
Within the confines of numerous factory columns, the semi-gantry crane, with its unique configuration of "single-sided outrigger + main beam overhang," opens up a new path for "spatial breakthrough" in lifting operations.
Technical Parameters:
| Lifting Capacity | 5~32 tons (mainstream 10/20 tons) |
| Main Beam Span | ( Outrigger spacing ): 7.5~28.5 m |
| Cantilever Length | 5~15m (customized ≤18m) |
| Lifting Speed | 8~16m/min (single speed/dual speed optional) |
Structural Code: The Spatial Magic of a Half-Gate Design
✅ Single-Sided Support: One side runs along the track, while the other is secured to the factory building columns/walls, saving 30% on track-laying costs and enabling renovations of existing plants without disturbing the building structure.
✅ Cantilever Extension: The main beam cantilevers up to 5-15 meters, flexibly covering the area outside the columns and resolving the problem of "excessively wide equipment that cannot be hoisted."
✅ Lightweight Configuration: Box-type outriggers + truss main beam (Q355B manganese steel) reduce deadweight by 25% compared to full-gate cranes while maintaining a lifting capacity of 10-32 tons.
Scenario Coverage: "Space Patching" from Workshops to Semi-Open-Air Areas
✅ In-Workshop: For hoisting molds and heavy parts in machining workshops, the cantilever arm covers the stacking area outside the columns, replacing forklift "blind lifts" at high altitudes.
✅ Semi-Open-Air Cargo Yard: For operations near warehouse awnings, the outriggers follow the tracks outside the awning, and the cantilever arm extends deep into the awning for loading and unloading, ensuring continuous operation in rainy and windy weather.
✅ Special Adaptation: The metallurgical version features a 600°C-resistant insulation layer, and the chemical version has an upgraded explosion-proof motor, enabling "plug-and-play" operation in extreme environments.
