Precision slip-free cable pulling for extrusion and processing lines
The JP-AC Series Caterpillar Haul-off is an inline cable pulling unit designed for smooth, slip-free traction in wire and cable extrusion lines. Twin opposing belt tracks grip the cable uniformly along a contact length — unlike capstan-wheel designs — distributing the pulling load without concentrating stress on a single point. This prevents surface marking and conductor deformation even on soft-insulation cables.
Three models address the full spectrum of production requirements. The JP-AC 150 is a compact, single-drive unit suited for small-diameter cables and lower-speed lines. The JP-AC 300 delivers mid-range pulling capacity with a dual-drive arrangement for stable tension at variable line speeds. The JP-AC 500 is the heavy-duty production model with servo-controlled variable-frequency drives, independent belt pressure adjustment, and closed-loop speed synchronisation — designed for demanding high-throughput cable lines where tension stability directly affects dimensional consistency.

Inline haul-off for insulation and sheathing extrusion — maintains constant line speed and tension to ensure uniform wall thickness and concentricity across the full production run.
High-force pulling for large-diameter HV cable constructions where high line tension is required — servo-controlled traction prevents belt slip and surface marking on premium cables.
Precise low-tension pulling for fibre optic and data cable lines — adjustable grip pressure prevents excess compression force on sensitive optical fibre bundles.
Soft compound rubber cables require gentle, distributed grip to avoid surface marking — belt contact length distributes load without the point-loading of capstan wheels.
Downstream haul-off for plastic pipe and profile extrusion — constant speed pulling maintains consistent wall thickness and prevents accordion deformation through the calibration section.
