China Haul-off Machine for Pipe Extrusion Line - Reliable Suppliers & Factory Solutions
Our Advantages
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
- 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 haul-off machinery is highly versatile, supporting pipe diameters ranging from small sizes up to 125 mm (ideal for composite, micro duct, and drip irrigation), standard sizes from 16 to 800 mm, and large-scale applications from 800 mm upwards.
How is synchronization accuracy maintained during the extrusion process?
We achieve high synchronization accuracy through coordinated drive motors. For start-up aids, synchronization is managed dynamically via a pilot frequency connected directly to the haul-off system.
What options are available for driving the caterpillars and belts?
The belts and caterpillars are driven individually by high-performance 3-phase motors. For applications requiring precise speed and positioning control, servo drives are available as an option.
How does the system handle thin-walled pipes?
To prevent deformation or damage to thin-walled pipes during haul-off, our systems feature integrated back pressure control alongside pneumatic contact pressure on the upper caterpillars.
What features optimize high-speed extrusion for small pipe diameters?
For small diameters up to 125 mm, the system supports extrusion speeds up to 300 m/min. It utilizes Poly-V belts for smooth running, lateral pipe guides for stability, and a pivotable top support to compensate for pipe twisting.
