The hauler of pipe line is driven by coupling and controlled by inverter.It has two types these are for pipe and profiles.

The hauler of extrusion line is driven by coupling and controlled by inverter.

1)Upper caterpillar adopt cylinder flexible pinched to suit for different pipe

diameter and keep contract pressure in reason.

2)Lower caterpillar is adjustable electrical as per pipe diameter.

3)Adopt V-shaped rubber bad with high friction factor.
