Caterpillar Haul-Off Manufacturers in India
Sai Extrumech is a leading caterpillar haul-off manufacturer in India, building belt (caterpillar) haul-off units that pull cable through the extrusion line at a precise, constant speed. Stable haul-off tension is essential for uniform insulation thickness and consistent line output — which is why cable producers across India and our export markets rely on Sai Extrumech haul-offs.
What Is a Caterpillar Haul-Off?
A caterpillar haul-off (belt haul-off) uses two opposing belts that grip the cable and pull it through the line at a controlled speed. The haul-off speed, together with the extruder output, sets the insulation wall thickness — if the haul-off surges or slips, the insulation thickness varies along the cable. A well-built caterpillar haul-off holds constant tension and speed for a uniform, in-spec product.

Frequently Asked Questions
Who makes the best caterpillar haul-off in India?
Sai Extrumech is among the leading caterpillar haul-off manufacturers in India, supplying constant-tension belt haul-offs engineered for stable line speed and uniform insulation.
Why is constant tension important in a haul-off?
Haul-off speed sets insulation wall thickness. Constant tension keeps the wall uniform along the cable and prevents thickness variation and rejects.
Can a haul-off be supplied separately?
Yes — we build haul-offs as standalone units or integrated into a complete extrusion line.
Key Features of a Quality Caterpillar Haul-Off
Because haul-off speed directly sets insulation wall thickness, the most important quality in a caterpillar haul-off is stable, repeatable speed and tension control. A good unit holds a constant pull even as line conditions change, uses belts sized correctly for your cable diameter range, and stays synchronised with the pay-off and take-up so the cable moves smoothly through the whole line. Build quality matters too: an industrial haul-off runs continuously for years, so durable construction and easy maintenance protect your uptime.
Sai Extrumech builds caterpillar haul-offs for exactly this — constant-tension control for uniform insulation, belt configurations across a wide diameter range, and rugged construction for continuous production. We supply them as standalone units or fully integrated into a complete extrusion line, matched to your extruder and take-up. With 25+ years of auxiliary-machinery engineering, our haul-offs keep your line speed and wall thickness in spec.
What size cable can your caterpillar haul-offs handle?
We build haul-offs with belt configurations for a wide range of cable diameters; the unit is matched to your specific cable range and line speed.
Can a haul-off be retrofitted to an existing line?
In many cases yes — share your line details and our engineers will advise on a haul-off that integrates with your existing pay-off, extruder and take-up.
