Advanced Haul off Machine for HDPE and PE Pipe Production Line
Product Overview
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.
Structural Features
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.
Performance Characteristics
High Traction Force
Capable of handling large-diameter and thick-wall HDPE pipes
Peak traction can reach up to 60,000 N depending on model
Precision Speed Control
Frequency inverter ensures synchronized speed with extrusion line
Suitable for pipes from small (6 mm) to large (800+ mm diameter)
Stable and Uniform Pulling
Even distribution of pulling force reduces:
Pipe ovality
Surface defects
Internal stress
Adaptability
Adjustable clamping for:
Different pipe materials (HDPE, PE, PP, PERT, and more)
Various wall thicknesses and diameters
Automation & Control
Integrated PLC control system
Touchscreen HMI for parameter setting
Automatic synchronization with cutter
Smooth Operation
Low vibration and noise
Continuous, non-stop operation for high productivity
