The QDL Lightweight Overhead Crane with Double Hook is designed for efficient material handling in industrial settings where space optimization and dual-load management are critical. These cranes combine compact, lightweight construction with dual-hook functionality to enhance productivity in applications requiring simultaneous or independent lifting of loads.
Dual-Hook System: Equipped with two hooks (main and auxiliary or two equal-capacity hooks) for handling multiple loads or balancing bulky materials.
Lightweight Design: Constructed with high-strength steel or synthetic ropes to reduce dead weight while maintaining durability (e.g., NLH model uses synthetic ropes for improved efficiency).
Adaptability: Available in single or double girder configurations:
Single Girder: Compact, cost-effective, ideal for moderate.
Double Girder: Higher lifting capacity (up to 300 tons) and stability for heavy-duty tasks.
Automation & Safety: PLC controls, anti-sway systems, overload protection, and emergency stops ensure precision and safety.
| Parameter | Double Girder Crane |
|---|---|
| Lifting Capacity | 50–300 tons |
| Span | 10.5–40.5m |
| Lifting Height | 12–60m |
| Lifting Speed | 0.63–63 m/min |
| Work Duty | A3–A8 (heavy-duty) |
| Power Supply | 380V, 50Hz, 3-phase |
Example Models:
QDL Double Girder Crane (Double Hook):
Capacity: 25–800 tons
Span: 10.5–34m
Lifting Speed: 0.15–11.5 m/min (dual-speed options)
Manufacturing: Assembly lines requiring dual-load handling (e.g., machinery parts, automotive components)
Warehousin: Efficient stacking and retrieval of materials in confined spaces.
Logistics: Loading/unloading cargo in ports or distribution centers.
Space Efficiency: Lightweight single girder models maximize vertical workspace, ideal for low-clearance facilities.
Cost Savings: Reduced energy consumption and maintenance costs compared to traditional heavy cranes.
Versatility: Dual hooks enable tandem lifting (e.g., balancing long beams) or separate operations (e.g., handling mixed loads).
Safety: Overload sensors, anti-collision systems, and emergency braking.
Comparison: Single vs. Double Girder
| Feature | Double Girder |
|---|---|
| Weight | Heavier, robust structure |
| Capacity | Up to 300 tons |
| Cost | Higher upfront cost |
| Use Case | Steel mills, shipyards |
Top Recommendations
Lightweight Crane: Best for moderate loads (20–100 tons) and facilities prioritizing space savings.
QDL Double Girder Crane: Ideal for heavy industries requiring high capacities (25–800 tons) and dual-hook precision.
European-Style Double Hoist: Combines automation and dual-speed hoists for complex operations.
