Capstan Manufacturers in India
Sai Extrumech is a leading capstan manufacturer in India, building the driven capstan units that pull conductor and cable through wire & cable lines at constant speed and tension. A capstan wraps the cable around one or more powered wheels to draw it forward smoothly — essential for stable drawing, extrusion and take-up. With 25+ years of engineering, we build capstans for our own lines and to match any existing line.
What Is a Capstan?
A capstan is a powered pulling device that draws wire or cable through the production line at a precise, constant speed. The cable wraps around a driven wheel (or belt-wrap arrangement), and the wheel’s rotation pulls it forward under controlled tension. Steady capstan speed keeps the whole line stable — if it fluctuates, insulation diameter and conductor tension drift.
Our Capstan Range
- Single-wheel capstans for standard conductor pulling
- Dual-wheel capstans for higher tension and better grip without slip
- Belt-wrap capstans where extra wrap contact is needed
- Motorised drive with precise, constant-speed control
- Sized to your conductor range, line speed and tension
- Synchronised with pay-off, extruder and take-up

Applications
Our capstans are used across power cable, building wire, submersible, solar and specialty cable lines, working with our caterpillar haul-offs, pay-off stands and take-up units. See the full extrusion line range from established cable extrusion machine manufacturers.
Frequently Asked Questions
What is a capstan in a cable line?
A capstan is a powered wheel or belt-wrap unit that pulls conductor or cable through the line at a controlled, constant speed and tension, so the process stays stable from pay-off to take-up.
What is the difference between a capstan and a caterpillar haul-off?
A caterpillar uses two belts to grip the cable over a flat length; a capstan wraps the cable around one or more driven wheels. Capstans suit round conductors and higher tensions; caterpillars suit flat or delicate profiles.
Do you make single and dual wheel capstans?
Yes. We build single-wheel, dual-wheel and belt-wrap capstans, sized to your conductor range, line speed and tension.
Can a capstan be matched to my existing line?
Yes. We size the capstan drive and wheel diameter to your conductor and synchronise it with your pay-off, extruder and take-up.
