Our Multi-layer Spooling Drum is purpose-built for long-distance lifting applications where extended rope travel and high-capacity spooling are essential. Unlike single-layer drums, this design allows multiple layers of wire rope to be wound neatly and evenly, providing significantly longer rope length without increasing drum size. Ideal for deep-well cranes, large-span gantry cranes, and port handling equipment, this drum ensures reliable performance, stable tension, and smooth operation even at extreme lifting heights.
Multi-layer Spooling Capability – Accommodates long lengths of wire rope in a compact drum size, perfect for high-rise or deep-drop lifting.
Even Rope Layering – Precision-machined grooves and guided winding ensure each layer sits uniformly, preventing rope crossover, crushing, or uneven wear.
Reduced Rope Stress – Optimized flange and groove design minimize friction between layers, extending rope service life.
Heavy-Duty Construction – Manufactured from high-strength alloy steel with heat treatment for maximum durability under continuous operation.
Smooth Long-Distance Hoisting – Stable winding and unwinding performance ensures consistent load control over extreme heights.
Customizable Configurations – Available in various diameters, barrel lengths, flange types, and groove profiles to meet specific project requirements.
Material Options And Process Advantages
We offer three material solutions for drum manufacturing, each selected based on application requirements:
| Material | Grade | Features & Applications |
|---|---|---|
| Gray Cast Iron | HT20-40 (min. HT200) | Cost-effective; requires aging treatment to relieve internal stresses. Suitable for standard-duty applications. |
| Cast Steel | ZG25, ZG35 (equivalent to ZG270-500) | High strength and toughness; requires annealing. Ideal for heavier load conditions. |
| Welded Steel Plate | Q235B, Q345B | Excellent structural strength; designed for high-capacity cranes and demanding performance requirements. |
Compared to traditional cast drums, welded steel plate construction is increasingly preferred in global markets, especially for large-diameter drums where cast options present manufacturing challenges.
