Single-girder Semi-gantry Crane: a "space-breaker" for workshop production lines
Next to the shot blasting equipment in the workshop, a bright yellow single-girder semi-gantry crane is quietly solving the problem of "equipment-intensive + limited lifting" - the single-sided support leg fits the factory column, and the digital load display screen jumps clearly. A "vertical transportation express line" is set up between the shot blasting, welding and other production lines, allowing the workshop space utilization and lifting accuracy to be simultaneously broken through.
Technical Parameters:
| Lifting Capacity | 5~20 tons (mainstream 10 tons) |
| Span | 7.5~25m (12~20m recommended) |
| Cantilever Length | 5~15m (customized ≤18m) |
| Lifting Height | Lifting height: 4~12m (clearance ≥3m) |
Single-sided Configuration: Creates a lifting channel in the workshop.
✅ Revolutionary Space: One side runs along the track, attached to the factory building columns, while the other side cantilevers out 5-12 meters. This transforms the "slots" near the shot blasting machine and welding area into a work area, saving 30% in track infrastructure costs during renovations.
✅ Structural Resilience: The Q355B manganese steel single beam is welded and inspected, with a mid-span static load deformation of ≤ 1/1000 of the span. Even when lifting workpieces weighing 5-20 tons (such as steel before shot blasting or heavy components after welding), it remains stable.
✅ Scenario Adaptability: Adapts to workshops with height restrictions (main beam clearance as low as 3 meters) and densely populated column areas, perfectly fitting next to shot blasting and painting lines, becoming a "handling hub between equipment."
Production Line Collaboration: A "Transport Hub" for Interconnected Equipment
🔹 Seamless Shot Blasting Line Integration: Precisely lift workpieces into the shot blasting chamber, and with the roller conveyor, achieve "automatic loading, shot blasting, and unloading," increasing flow efficiency by 50%;
🔹 Aerial Assembly in the Welding Area: Lifting heavy welds, coupled with robotic arms, allows for "air assembly," eliminating the tedious process of turning parts on the ground;
🔹 Customization: Explosion-proof models are suitable for paint shops, while high-temperature-resistant models are compatible with heat treatment lines, becoming the "moving joint" of the production line.
