Reeling Cable for Spreader & Crane Cable Baskets
Our reeling cable for spreader/basket systems is a heavy-duty power and control cable engineered specifically for vertical reeling applications in harsh environments. Designed to power crane spreaders, hoist trolleys, and other suspended equipment, this cable ensures uninterrupted power and signal transmission where standard cables fail.
Key Benefits & Construction Features
This reeling cable combines mechanical durability with electrical reliability. The core differentiator is its integrated stabilization and reinforcement system, which prevents damage and downtime in high-wind and high-cycle applications:
- Vertical Stability (Anti-Pendulum Design): An optional integrated 铅珠链 (lead-weighted chain) runs through the cable core. This adds mass to prevent the cable from swinging, twisting, or snagging in strong winds, a critical safety feature for outdoor cranes on construction sites, shipyards, and port terminals.
- Central Strain Relief Element: High-tensile steel wire rope or Kevlar aramid fiber strength members absorb the dynamic stress of constant reeling and vertical weight, protecting the copper conductors from elongation and fatigue failure.
- Full Environmental Protection: The robust PUR (polyurethane) outer jacket provides exceptional resistance to abrasion, mineral oils, hydraulic fluids, UV radiation, ozone, and salt spray corrosion. This makes the cable ideal for marine and coastal applications in shipyards and port cranes.
- Flame Retardance (Optional): Flame-retardant jacket compounds are available to meet site-specific fire safety requirements.
Target Applications
This cable is purpose-built for vertical cable basket (蓄缆筐) storage systems that re-spool the cable under tension. Specifiers and end-users typically deploy this cable in:
- Container & Bulk-Handling Cranes (STS, RTG, Gantry)
- Shipyard Cranes & Transporter Carts
- Construction Site Tower Cranes & Hoists
- Mining Material Handling & Vertical Shaft Cages
- Waste Processing & Incineration Plant Grabs
- Railway Platform Heavy-Duty Equipment
- Medium-to-Large Industrial Equipment Reeling Systems

FAQ
What is the purpose of the铅珠链 inside a reeling cable? The integrated铅珠链 acts as a ballast weight. In vertical cable basket systems, it increases the cable’s self-weight to prevent it from being blown by high winds, which could cause twisting, cage-hooking, or erratic winding onto the drum. This is a standard requirement for outdoor cranes like ship-to-shore or gantry systems operating in exposed areas.
Is a Kevlar strength member or a steel wire rope core better for my application? Both provide tensile strength to prevent conductor breakage, but the choice depends on the application. Steel wire ropes offer extremely high strength and are standard for heavy vertical lifts. Kevlar (aramid fiber) is lighter and non-metallic, which might be preferred if total basket weight is a critical factor. Our engineers can specify the correct tensile load rating based on your total suspended cable length and basket capacity.
Can you supply a composite cable with fiber optic and power cores in the same jacket? Yes. We frequently manufacture composite reeling cables that combine power conductors with fiber optic elements or Cat6a control pairs within a single, flexible PUR jacket. This simplifies installation inside the cable basket and improves reliability. Contact us with your I/O list for a flat cable or round cable design proposal.
What are the key differences between a PVC and a PUR jacket for reeling applications? While PVC is a cost-effective option for indoor use, PUR (polyurethane) is the industry standard for crane reelers. PUR offers far superior abrasion resistance, notch resistance, and chemical stability against hydraulic fluids. More critically, PUR maintains flexibility down to -45°C and resists thermal aging up to +70°C, preventing the jacket from cracking under the constant flexing and outdoor exposure typical of crane duty cycles.
