Multiple caterpillar haul-offs for thin-walled pipes and big pipe dimensions
●  Diameter range:20-1200mm

Technical Note
●  V-type rubber block have been connected with chain direct；
●  Even if a low coefficient of friction between the tubes and the rubber blocks, the cylinder with large size can still guarantee a very high traction
●  Using the German Lenze company's controller and speed-down motors,  All tracks are parallel to be guided
●  The nether track can adjust to the diameter position through a mechanical or electrical method, but the upper one must be pressed onto the surface of the tube after a mechanical pre-setting.
●  Track drive: Each track drived by a separate induction motor, Through the digital controller to achieve synchronization control, Ensure that all tracks are precisely synchronized speed.
●  Efficiency
●  The best production reliability
