Suspended Single-girder Bridge Crane: "high-altitude breakthrough" in low-rise factory buildings
When factory floor height becomes a "tightening curse," traditional cranes are daunted. Suspended single-girder cranes use "inverted magic" to transform low spaces into efficient handling areas.
An installation philosophy that slims down factories
No corbels or floor rails, simply "hang" beneath building beams!
Space Snatcher: Attached to concrete beams/steel purlins for installation, it saves over 30% of floor space (e.g., even in 3.5-meter-high floors), eliminating the need to demolish walls when renovating old factories.
Lightning Deployment: Modular main beams + prefabricated track allow assembly in half a day, cutting construction time in half, enabling early production and profitability.
Technical Parameters:
| Lifting Capacity | 1~16 tons (customizable up to 20 tons) |
| Span Range | 6~22.5 meters (standard gauge, non-standard customization supported) |
| Lifting Height | 6~18 meters (limited by the net height of the factory building, the minimum clearance must be ≥7 meters) |
| Work Duty | A3 (light load) ~ A5 (medium load, 8 hours continuous operation) |
| Control Method | Wired handle + wireless remote control (100 meters), support PLC networking |
Core advantages:
1. Space Adaptability: Breaking Through Factory Building Constraints
No Infrastructure Installation: Directly hang building beams/steel structures, eliminating brackets and floor rails. This reduces installation costs by 40% for retrofitting old factories and allows deployment with a clear height of 3.5 meters.
Maximum Clearance Utilization: The hook is ≤300mm from the wall (European model), freeing up 20% of vertical space and adapting to densely packed racks and production lines.
2. Structural Performance: Lightweight and Efficient
30% Reduced Weight: Utilizing Q345B high-strength steel and modular design (such as the KBK system), the 10-ton system is one-third lighter than traditional designs, reducing load-bearing pressure on the factory floor.
Modular Expansion: Tracks and main beams can be freely connected, allowing for rapid conversion to double beams or telescopic beams. Sharing track with multiple main beams increases efficiency by 50%. 3. Precise Operation: Stable and Convenient
Frequency Control for Stable Lifting: Dual frequency conversion speed regulation ensures sway of ≤5cm when lifting a 15-ton steel coil, with millimeter-level alignment.
Wireless Remote Control: 100-meter remote control with smart display doubles single-operator efficiency in complex workshops.
4. Safety Protection: Multiple Safeguards
Dual Brakes + Dual Limits: Electromagnetic magnetic brake (0.3-second locking) + mechanical brake, with electronic limits for lifting and travel, prevent falls and overshoots.
Intelligent Warning: Real-time alarms for overload (±5% accuracy), overheating, and phase sequence protection, and fault self-diagnosis connected to your phone.
5. Cost Control: Full-Life Cycle Cost Savings
Procurement Savings: 30% less than a double-beam crane, modular pre-assembly reduces installation time to 3 days.
Maintenance Savings: IP54 motor + wear-resistant wheels, ≤2 maintenance per year, variable frequency drive saves 25% energy, and reduces hoist costs over three years.
