Keep Your Machinery Moving Without Interruption
In heavy industrial environments, cable failure equals downtime. Whether it’s a gantry crane in a busy port or a hoist in a manufacturing plant, the cables powering your movement need to withstand constant bending, tension, and environmental stress.
Our 12-Core 0.5mm² Flat Travelling Cable is engineered specifically for dynamic festoon systems and elevators where space is tight and reliability is non-negotiable. Unlike round cables that twist and corkscrew under repetitive motion, our flat design stacks neatly, glides smoothly, and offers a significantly tighter bending radius.
Manufactured by Shanghai Ruosheng Wire and Cable Co., Ltd., this cable represents the intersection of durability and precision engineering, designed to meet the rigorous demands of the European and global markets.
Why Switch to Flat Travelling Cables?
1. Zero Twisting or “Corkscrewing”
The geometry of a flat cable naturally resists twisting. When used in festoon systems or cable tracks, the cable flexes in only one plane. This eliminates the internal torsional stress that typically causes round cables to deform and fail prematurely.
2. Space-Saving Stackability
When your crane trolley or elevator car moves, cables need to fold efficiently. The 12-core flat profile allows multiple cables to stack directly on top of one another within the cable track or trolley system. This reduces the width of the towing chain and prevents tangling during high-speed operation.
3. Extreme Flexibility & Flex-Life
Inside the jacket, we use finely stranded Class 5 or Class 6 oxygen-free copper conductors. This high-flex stranding ensures that the copper doesn’t work-harden or break after thousands of bending cycles. It delivers consistent power and signal transmission, even in 24/7 operations.
4. Built for Harsh Environments
The outer sheath is formulated for industrial resilience. It resists:
- Abrasion: Withstands dragging and friction in cable chains.
- Oil & Chemicals: Suitable for machine tool environments where coolants are present.
- Weather: UV-stabilized options available for outdoor overhead cranes.

Frequently Asked Questions (FAQ)
Q: Can this cable be used outdoors?
A: Yes, but please specify your environment when ordering. For outdoor applications exposed to direct sunlight and extreme cold, we use a specialized UV-resistant and weather-proof jacket compound to prevent cracking.
Q: What is the benefit of a 0.5mm² cross-section for this cable?
A: The 0.5mm² size is ideal for control signals and low-power transmission. It balances current-carrying capacity with physical size, keeping the cable lightweight and flexible, which reduces the mechanical load on your festoon trolleys.
Q: How do I determine the minimum bending radius?
A: For safe operation, the bending radius should be at least 10 times the thickness of the cable. For example, if the cable is 4mm thick, the bend radius should be no tighter than 40mm. Exceeding this limit can damage internal copper strands.
Q: Can you customize the length and core color?
A: Absolutely. As a direct manufacturer, Ruosheng offers full customization. We can cut to specific lengths, provide numbered or colored cores, and even reinforce the cable with steel wire for long vertical suspension heights (over 80m).
