Rubber spreader basket cables are specialist heavy-duty flexible power and control cables engineered for the extreme demands of container crane spreaders, reach stackers, and rubber-tyred gantry crane basket assemblies. These cables endure millions of flexing cycles in free-hanging basket configurations, exposure to sea air, rain, oil, and heavy mechanical impacts — while maintaining reliable power and signal transmission to spreader motor drives and sensors.
Constructed with extra-fine-wire stranded copper conductors, EPDM rubber insulation, integrated power and control cores, and a robust neoprene outer sheath. Available in combined power (up to 6 mm²) and control (0.5–1.5 mm²) configurations, with optional shielded signal cores and earth monitoring conductors.
| Parameter | Value |

| Control Core Voltage | 300/500V AC |
| Insulation | EPDM rubber |
| Sheath | Neoprene / chloroprene rubber |

| Control Cross-sections | 0.5–1.5 mm² |
| Temp. Range | ‑40°C to +90°C |
Spreader basket cables operate in free-hanging mode — unlike festoon cables on hangers. The cable must support its own weight while flexing, making conductor class and lay length critical parameters. Always specify the free-hanging length and number of daily cycles when requesting a custom design.
