Caterpillar Tractor
1.automatically conform to different specs of pipeline
2.keep good contact pressure with pipeline

                                                       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
