In high-volume power cable manufacturing, handling large-diameter, heavy reels efficiently is one of the biggest challenges. The RLB Gantry Type Take up and Pay off Stand Unit is specifically engineered for heavy-duty cable production lines — including extruders, rewinding stations, taping machines, and armouring lines — where drum diameters reach up to 5000 mm and load capacities exceed 55 tons.
With its robust gantry structure, precision track-moving system, and intelligent MMI+PLC control, this unit ensures straight cable feeding and take-up, minimal tension variation, and seamless non-stop operation when configured with double pay-off and double take-up systems.
Advanced Design & Operational Benefits
- Track Moving Device: Keeps the cable path perfectly straight during pay-off and take-up, eliminating side pull and reducing cable damage.
- Double Pay-off / Double Take-up Capability: The front machine can shift from the center position, allowing rear cables to pass through without stopping the line — maximizing uptime in continuous production.
- Intelligent Control System: MMI+PLC interface for preset traversing pitch, speed synchronization, and torque/speed drive mode. Ensures precise, repeatable performance across the entire drum range.
- High Load Capacity & Versatility: Supports drum diameters from 1250 mm to 5000 mm and cable outer diameters up to 180 mm, with traversing precision of 1–2 %.
- Smooth & Reliable Operation: Heavy-duty construction with low-maintenance components delivers stable performance even at high line speeds (up to 80 m/min on smaller models).
These features translate into higher throughput, lower scrap rates, reduced labor, and consistent cable quality across extrusion, stranding, taping, and armouring processes
Working Principle – Reliable Technology You Can Trust
Our gantry type pay-off and take-up employs a rigid gantry frame with walking beams and precision cable trays. AC variable-frequency drives deliver uniform, high-precision winding and unwinding speeds while maintaining stable tension. The integrated PLC system enables seamless linkage with upstream extruders, stranding machines or armouring lines, achieving true automation and Industry 4.0-ready connectivity.
Structural advantages include adjustable drum support fixtures, heavy-duty drive systems with precise torque control, and user-friendly electrical cabinets with single/joint control options — designed for 24/7 operation in demanding cable factories worldwide.
