Introduction of Caterpillar Tractor:

1.Caterpillar drive is controlled by direct-connection frequency variation
2.Upper caterpillar adopts cylindar soft compression which can automatically conform to different specs of pipeline and keep good contact pressure with pipeline; lower caterpillar can be adjusted by electricity vertically conforming to specs of pipeline.
3.Adopt v type rubber block with high friction coefficient 



The haul-off machine successively and automatically haul-off the stiffen pipes from the extruder die head. It has a 3 KW alternative current frequency-changing motor to drive the gear box for reduction of speed. The gear box can drive the upper and downside caterpillars. The upper caterpillar, by the tight press of the cylinder, can move simultaneously with the extruder. This ensures the haul-off reliability and stability.
