Heavy‑Duty Cable Reel for Crane & Electric Flat Trolley | Power & Lighting Extension Cable

In industrial environments, cable management isn’t just about tidiness—it’s about safety and operational continuity. Loose cables on a crane or electric flat trolley are a trip hazard and a maintenance nightmare waiting to happen.

The Ruosheng Heavy-Duty Cable Reel is engineered to solve these specific challenges. Unlike standard commercial reels, we build ours to withstand the repetitive winding and unwinding cycles of automated machinery. Backed by Shanghai Ruosheng Wire and Cable Co., Ltd.’s expertise in manufacturing high-flexibility drag chain cables, this system ensures your power supply remains consistent, even under constant motion.

Why Choose Ruosheng Cable Reels?

We don’t just assemble reels; we understand the cable inside them. With over 100 varieties of special cables developed in-house, we pair the right mechanical reel structure with the perfect cable type to prevent internal wire breakage—the #1 cause of reel failure.

1. Built for Constant Motion

Standard cables stiffen and crack when wound repeatedly. We utilize our proprietary High-Flexibility Drag Chain Cable technology within the reel. This ensures the copper conductors and insulation withstand thousands of retraction cycles without fatigue, making it ideal for gantry cranes and mobile transfer carts.

2. Rugged Industrial Construction

The reel body is constructed from heavy-gauge steel with a corrosion-resistant powder coating. Whether it’s installed on an outdoor port crane exposed to the elements or a factory floor transfer trolley, the casing protects the internal slip rings and springs from impact, dust, and moisture.

3. Consistent Tension Control

For electric flat trolleys and hoists, maintaining the right tension is critical. Too loose, and the cable gets run over; too tight, and the connector snaps. Our spring-driven (or motorized, depending on length) mechanism provides smooth, constant tension that adapts to the speed of your equipment, ensuring the cable lays flat and retracts safely every time.

4. Versatile Application

While optimized for cranes and electric flat trolleys, this reel is equally effective as a heavy-duty power and lighting extension solution for large workshops. It supports long-distance power transmission for mobile lighting towers and maintenance tools.

Frequently Asked Questions (FAQ)

Q: Can this cable reel be used outdoors?
A: Yes. The unit features an industrial-grade housing with high IP ratings (typically IP55 or IP65) and corrosion-resistant coating, making it suitable for outdoor cranes and damp environments.

Q: What is the maximum cable length available?
A: We offer various drum sizes. Spring-driven models typically handle up to 30-50 meters, while our motorized versions can manage lengths exceeding 100 meters for long-distance electric trolleys. Contact us for your specific length needs.

Q: My current reels keep failing because the internal cable breaks. How is yours different?
A: This is our specialty. Shanghai Ruosheng is a cable manufacturer first. We use specialized “high-flex” cables designed specifically for dynamic motion, rather than standard static cables. This significantly extends the lifespan of the unit.

Q: Do you offer customization for specific plugs or connectors?
A: Absolutely. As a direct manufacturer, we can terminate the cables with the specific industrial connectors (e.g., CEE, aviation plugs) required for your machinery setup.

Q: What is the lead time for an order?
A: For standard models, we often have stock ready for immediate dispatch. Custom voltage or length configurations typically require 7-14 days for production and testing.
