China Haul-off Machine for Pipe Extrusion Line - Suppliers & Factory Custom Solutions
Our Advantages
Robust design built for durability and long-term industrial operations.
Belts and caterpillars driven individually by 3-phase motors, optionally as servo drives.
High haul-off forces achieved due to high motor torque and pressure cylinders.
High synchronization accuracy with coordinated drive motors.
Back pressure control specifically developed for thin-walled pipes.
Electric adjustment of all caterpillars to match precise pipe diameter.
Upper caterpillars with pendulum support and pneumatic contact pressure.
Integrated control system managed via an intuitive touch screen interface.
Our Offer
For pipes from 16 to 800 mm
- Starting from the double track extension, the design is tightened in the opposite direction, which can firmly lock the pipe and achieve different sizes from 16-800mm.
- Bottom caterpillars manually/electrically adjustable.
- Start-up aid mounted on haul-off for saving space and synchronizing via pilot frequency.
For pipes from 800 mm upwards
- Multiple caterpillar haul-offs (6-14) with V-shaped rubber studs.
- Electrically adjustable caterpillars at top and bottom.
- Start-up aids up to 180 kN tractive force, synchronized with haul-off via pilot frequency.
- Deflection rollers and rope guides of start-up aids on tilting frame at the outlet end.
For small diameters up to 125 mm
- Belt haul-offs with Poly-V belts for smooth running (especially composite, micro duct and drip irrigation).
- Extrusion speeds up to 300 m/min.
- Extrusion height adjustable via hand wheel and fixed stop electrically adjustable.
- Easy access for belt change due to quick belt change system.
- Lateral pipe guides for high-speed extrusion.
- Pivotable top support to compensate for twisting of the pipe during extrusion.
Frequently Asked Questions
What range of pipe diameters do your haul-off systems support?
Our range covers pipe diameters starting from small sizes up to 125 mm (specifically for composite, micro duct, and drip irrigation), medium ranges from 16 to 800 mm, and large-scale applications from 800 mm upwards.
How is synchronization accuracy maintained in your haul-off machines?
We achieve high synchronization accuracy using coordinated drive motors. The belts and caterpillars are driven individually by 3-phase motors, which can optionally be configured as servo drives.
Do you offer solutions for processing thin-walled pipes?
Yes, our systems include integrated back pressure control specifically designed to handle and protect thin-walled pipes during the haul-off process.
What is the maximum extrusion speed for small diameter pipes?
For small diameters up to 125 mm, our belt haul-offs equipped with Poly-V belts can support high-speed extrusion lines operating at speeds up to 300 m/min.
How are the caterpillars adjusted for different pipe diameters?
Our haul-offs feature electric adjustment of all caterpillars to match the exact pipe diameter. For larger pipes, this includes electrically adjustable caterpillars at both the top and bottom.
