In high-volume power cable manufacturing — particularly for extra-high-voltage (EHV) and high-voltage (HV) lines used in infrastructure, renewables, and data-center projects — handling large-diameter, heavy reels efficiently remains one of the most critical bottlenecks. The Gantry Type Take-up and Pay-off Stand Unit is purpose-built for these demanding environments. It integrates seamlessly with extruders, rewinding stations, taping machines, steel-tape/wire armoring lines, and heavy stranding equipment.
Designed for drum diameters from 1250 mm to 5000 mm and load capacities exceeding 55 tons, this robust gantry system ensures straight cable feeding, minimal tension variation, and true non-stop operation when configured in double pay-off or double take-up mode. The result: higher throughput, lower scrap rates, reduced labor intervention, and consistent cable quality that meets stringent international standards (IEC, ASTM, and customer-specific requirements).
Conception avancée et avantages opérationnels
- Precision Track-Moving Device — Maintains perfectly straight cable path during pay-off and take-up. Eliminates side pull, reduces mechanical stress on insulation and sheathing, and minimizes cable damage or ovality — critical for EHV performance and long-term reliability.
- Capacité de double remboursement / double absorption — Front unit shifts laterally from center position, allowing the rear cable to pass through without line stoppage. This configuration maximizes uptime on continuous high-output wire extrusion lines and armoring processes, directly improving overall equipment effectiveness (OEE).
- Intelligent MMI + PLC Control System — User-friendly interface for preset traversing pitch, line-speed synchronization, and selectable torque or speed drive modes. Delivers repeatable, high-precision performance across the full drum range with closed-loop feedback for stable tension.
- Capacité de charge élevée et polyvalence — Handles drum diameters 1250–5000 mm, cable outer diameters up to 180 mm, and traversing precision of 1–2 %. Suitable for a wide range of power cables, from medium-voltage distribution to extra-high-voltage transmission.
- Smooth, Reliable High-Speed Operation — Heavy-duty structural components, premium bearings, and low-maintenance design deliver stable performance at line speeds up to 80 m/min (smaller models) while synchronized with upstream equipment. Built for 24/7 operation in demanding factory environments worldwide, including high-ambient-temperature and dusty conditions common in Middle East projects.
These engineering features translate into measurable gains: increased production throughput, significantly reduced scrap from tension or alignment issues, lower manual handling requirements, and superior finished cable quality.
Principe de fonctionnement – Une technologie fiable à laquelle vous pouvez faire confiance
The RLB gantry system employs a rigid gantry frame with walking beams and precision cable trays that support the drum securely. AC variable-frequency drives (VFD) provide uniform, high-precision winding and unwinding while maintaining stable tension through torque or speed control modes with closed-loop feedback.
The integrated PLC system enables seamless synchronization with upstream extruders, stranding machines, or armoring lines — achieving true automation and Industry 4.0-ready connectivity (optional remote diagnostics, data logging, and OPC-UA interface). Adjustable drum support fixtures (pintles/clamps), heavy-duty drive systems with precise torque control, and user-friendly electrical cabinets (single or joint control) are all engineered for continuous, trouble-free service.
Safety interlocks, overload protection, and emergency systems are standard. The design prioritizes operator safety and ease of maintenance while delivering the long-term reliability expected from a trusted cable machinery supplier.
