Gantry Crane Reeling Cable (Reeling Drum Cable for Overhead Cranes)
Engineered for the demanding motion and environmental conditions of crane and material handling systems, our gantry crane reeling cable delivers exceptional flexibility, mechanical toughness, and resistance to oils, chemicals, and extreme temperatures. Designed as a high-performance drum reeling cable, it reliably powers, controls, and communicates on gantry cranes, portal cranes, and heavy-duty mobile equipment operating at AC rated voltages up to 0.6/1 kV (standard stock model rated 300/500 V; higher voltage grades available on request).
Where installation spaces are tight, the cable’s optimized minimum bending radius ensures safe, long-lasting performance under constant reeling and flexing. With a rugged construction built to withstand crushing, abrasion, and accidental mechanical impacts, it significantly reduces downtime and maintenance in harsh industrial environments.
Key Applications for Gantry Crane Reeling Cables
- Garbage grab cranes and waste handling equipment
- Power station gantry cranes and EOT (Electric Overhead Traveling) cranes
- Shipyard and dock-side gantry cranes
- Hoisting systems, ship unloaders, and stacker-reclaimers
- Large container bridge cranes and RTG (Rubber-Tired Gantry) cranes
- Any cable reel, drum, or festoon system requiring continuous flex and torsion resistance

Construction & Performance Benefits
- Superior Flexibility & Torsion Resistance: The extra fine Class 6 copper stranding and specially formulated PVC insulation allow repeated bending and twisting on cable drums and pulleys without conductor breakage.
- Excellent Cold Resistance: The combination of insulation and PURJ jacket maintains flexibility even in sub-zero temperatures down to -40 °C (fixed) without cracking.
- Oil, Chemical & Hydrolysis Resistance: The polyurethane jacket provides a strong barrier against industrial oils, greases, hydraulic fluids, and moisture, making it ideal for steel mills, ports, and waste-to-energy plants.
- Electromagnetic Interference Protection: The high-density tinned copper braid shielding (≥80% coverage) safeguards signal and control circuits from EMI, ensuring stable data transmission for automation and safety systems.
- Mechanical Toughness: Robust outer sheath resists abrasion, cuts, and impacts, extending service life in harsh indoor and outdoor environments. The cable is also UV and weather resistant.
- Compliance & Traceability: Conductors meet VDE 0295 / IEC 60228 Class 6. The complete cable can be marked CE, and further certifications (e.g., RoHS, specific national standards) can be supplied as required by your project.

FAQ
What is a gantry crane reeling cable and how is it different from standard flexible cable?
A gantry crane reeling cable is designed specifically for continuous winding and unwinding on cable drums or reels under high mechanical stress. Unlike standard flexible cables, it features enhanced torsion resistance, a polyurethane jacket for superior abrasion and oil resistance, and extra fine conductor stranding to survive repeated bending and stretching cycles without early failure.
Can this cable be used outdoors in freezing conditions?
Yes. The cable’s jacket and insulation are rated for fixed installations down to -40 °C and dynamic (reeling) use down to -5 °C. It remains flexible and does not crack in cold storage yards, portside installations, or winter construction sites.
What voltage options are available?
Our standard stocked reeling cable is rated 300/500 V, which covers many control, signal, and moderate power applications. We also manufacture versions up to 0.6/1 kV for heavier power transmission on large gantry cranes. Simply specify your voltage requirement when requesting a quote.
Does this cable have shielding for control and communication signals?
Our standard gantry crane reeling cable is available with a tinned copper braid shield providing ≥80% coverage. This effectively protects against electromagnetic interference (EMI) and cross-talk, making it suitable for variable frequency drive (VFD) control, encoder feedback, and data transmission lines integrated into the cable.
How do I determine the correct cable length and drum capacity?
Measure the total horizontal and lifting travel distance of your crane, add allowance for dead wraps on the drum, and consider a safety factor for re-tensioning. If you provide the drum dimensions, number of permitted layers, and travel length, our application engineers can recommend the optimal cable length and outer diameter to match your reel system.
Can I get a sample before placing a bulk order?
Absolutely. We routinely provide free cable samples (typically 1–3 meters) for physical inspection, bending tests, and approval according to your project specifications. Just send us your shipping details and preferred courier account number.
