Semi-gantry Crane: Unilaterally tearing away the constraints of space, making "safe production" ingrained in the bones and blood
Next to the factory building's outer wall, a bright yellow semi-gantry crane stands quietly - its single-sided outrigger supports the heavy beam like a steel arm. The slogan "Safe Production, Quality First" on the main beam is not only a warning, but also a safety gene engraved into the design, customizing the dual solution of "spatial breakthrough + intrinsic safety" for lifting operations in the factory's extended area and semi-open-air cargo yard.
Technical Parameters:
| Lifting Capacity | 5~32 tons (main hook), auxiliary hook 3.2~10 tons |
| Span | 12~35 meters (outrigger distance) |
| Cantilever Length | 5~15 meters (main beam single-side overhang) |
| Lifting Height | 6~18 meters (hook to ground) |
| Work Duty | A 3-A 5 |
Unilateral Structure: Turns Factory Columns into "Natural Teammates"
✅ Spatial Magic: One leg runs along the track, while the other "hangs" on the factory column/wall, eliminating the cost of half the track and allowing renovations of old factories without disturbing the building's structure.
✅ Cantilever Breakthrough: The main beam cantilevers 5-15 meters, extending like an arm across the factory wall, transforming the "blind spot" outside the column into an operational area, resolving the pain point of "excessively wide equipment that can't be lifted."
✅ Lightweight and Sturdy: The Q355B manganese steel box-type main beam and truss legs are 25% lighter than full-gantry cranes, yet can withstand loads of 5-32 tons. Mid-span deformation is ≤ 1/1000 of the span, ensuring rock-solid stability when lifting steel and molds.
Suitable for all scenarios:
Outside the workshop: Connecting to production lines, lifting heavy equipment, and using the boom to reach the material storage area outside the columns;
Semi-open yard: Outriggers operate outside the canopy, while the boom extends inside for loading and unloading, ensuring continuous operation in windy or rainy weather;
Specialized customization: Metallurgical versions withstand temperatures up to 600°C, explosion-proof versions for advanced work areas, and corrosion-resistant versions for marine salt spray.
