The Advanced Haul-Off Machine (also called a traction unit) is a critical downstream component in HDPE/PE pipe extrusion lines. It is designed to continuously pull the extruded pipe from the cooling system at a controlled and synchronized speed, ensuring dimensional accuracy and surface quality.

In a typical HDPE pipe production line, the haul-off machine operates after:

• Extruder
• Vacuum calibration tank
• Cooling tank

It ensures stable pipe movement before cutting and stacking.

• Multi-pillar / multi-claw design (2-12 belts or claws)
• Rubber belt or block traction system for non-slip grip
• Hydraulic or pneumatic clamping system
• Heavy-duty frame with adjustable alignment
• AC motor-driven with frequency control

The multi-claw system distributes traction force evenly across the pipe circumference, improving stability and preventing deformation.

• Capable of handling large-diameter and thick-wall HDPE pipes
• Peak traction can reach up to 60,000 N depending on model

• Frequency inverter ensures synchronized speed with extrusion line
• Stepless speed regulation maintains uniform wall thickness

• Suitable for pipes from small (6 mm) to large (800+ mm diameter)

• Even distribution of pulling force reduces:
  • Pipe ovality
  • Surface defects
  • Internal stress

• Adjustable clamping for:
  • Different pipe materials (HDPE, PE, PP, PERT, and more)
  • Various wall thicknesses and diameters

• Integrated PLC control system
• Touchscreen HMI for parameter setting
• Automatic synchronization with cutter

• Low vibration and noise
• Continuous, non-stop operation for high productivity
