Single-girder crane: The "air precision arm" of the pressure vessel workshop, heavy load without crushing the factory, millimeter-level breakthrough
In the pressure vessel workshop, lifting a hundred-ton tank is a millimeter-scale battle: a 1cm misalignment can ruin all weld alignment; traditional overhead cranes are overloaded, causing deformation and cracking in the factory building's steel beams; the lifting process swings like a pendulum, forcing workers to closely monitor and not leave their posts...
Single-girder overhead cranes, with their "lightweight" design and precise control, are rewriting the efficiency equation for heavy-duty lifting.
Technical Parameters:
| Lifting Capacity | 1~20 tons (mainly suitable for pressure vessel segmentation/tank lifting, larger tonnage can be customized) |
| Span | 7.5~22.5 meters (matching the width of the workshop and maximizing the use of working space) |
| Lifting Height | 6~30 meters (meet the vertical lifting requirements of multi-story factories or high-station tanks) |
| Work Duty | A 3~A 5 (corresponding to medium to heavy industrial conditions, suitable for continuous operation in pressure vessel workshops) |
1. Single-girder structural revolution: "Reducing the burden" on factories, even in older factories.
Using Q345B manganese steel single-girder bridge, the crane's deadweight is 30% lower than a double-girder crane, slashing the load-bearing requirements on the factory building by half—no steel beam reinforcement is required for renovations of older factories, saving 30% in capital construction costs.
Adaptable to spans of 5-20m (customizable), the large-scale pressure vessel workshop in the image perfectly demonstrates its "stress-free long-distance lifting" capabilities.
2. Millimeter-level precision: Lifting is like "surgery," with one-time docking.
Variable frequency speed regulation + anti-sway algorithm: Continuously control lifting/operating speeds, with a hoist swing of ≤5mm and a positioning accuracy of ±2mm for 100-ton tanks, reducing welding rework by 80%.
Equipped with an intelligent positioning system, the crane automatically returns to its preset lifting point, allowing workers to start and stop with a single button, increasing efficiency by 50%. 3. Heavy-Duty Design: Rated lifting capacity of 5-20 tons, ready to tackle tough challenges.
The main beam is shot-peened and spray-coated for corrosion protection, achieving a tensile strength of 450 MPa. Equipped with a G80-grade hook, it easily lifts pressure vessel segments (10-50 tons per segment).
The tank lifting scene in the picture demonstrates its rock-solid stability under heavy loads.
