Servo Six-Claw Pipe Haul-Off Machine (280–630 mm): Precision Traction for Large-Diameter Pipe Lines
— An industrial-grade servo-driven six-jaw haul-off engineered for stable traction, uniform clamping, and smart line synchronization in large-diameter PVC/PE/HDPE pipe extrusion.
Why Choose a Servo Six-Claw Haul-Off for 280–630 mm Pipes
High-Torque, Closed-Loop Traction
- Six independent 1.5 kW servo motors deliver precise, closed-loop control for each traction belt, ensuring consistent pulling force and steady line speed.
- With a maximum traction force of 36,000 N and a speed range of 0.1–3 m/min, the unit maintains stability during heavy-wall and large-diameter pipe production.
Large-Diameter, Gentle Handling
- 1-inch wear-resistant rubber blocks (traction pads) cover the full clamping range of 280–630 mm, providing high friction with minimal surface marking.
- Six-claw synchronized traction evenly distributes pressure, reducing ovality and wall-thickness variation on big-bore pipes.
Industrial-Grade Build for Longevity
- 12 mm thick steel plate for the haul-off frames and 20 mm thick wall plates deliver rigidity and vibration damping.
- Carbon steel chains and a rectangular tube welded frame ensure durable, low-maintenance operation in 24/7 extrusion environments.
Key Features of the 280–630 mm Servo Six-Jaw Haul-Off
Servo Drive and Intelligent Control
- Servo motors: Sine (正弦) brand, 1.5 kW each, paired with K-series gear reducers (Jansen or RedSun).
- Speed control: Sine servo controllers provide smooth, accurate speed ramping and torque response.
- Digital readout: Dongqi display shows real-time line speed for quick monitoring and process consistency.
Stable Clamping and Easy Adjustments
- Upper haul-off frame: pneumatic clamping for quick, repeatable engagement across pipe sizes.
- Lower haul-off frame: motor-driven lift/press mechanism for precise pressure control and diameter changeovers.
- Center height: configurable to buyer’s specification for seamless integration with existing extrusion lines.
Quality Electrical Components
- Contactors, indicators, and push-buttons from Schneider and Chint ensure reliable operation and easy servicing.
- Terminal blocks by Tend provide secure, organized wiring for long-term stability and safety.
Applications: Built for Big-Pipe Markets
Building & Infrastructure
- Water supply, drainage, and sewer pipelines (PVC/HDPE) where consistent traction and low ovality are critical.
- Cable protection ducts and conduit requiring uniform surface finish at slow line speeds.

How the Six-Claw Servo Haul-Off Elevates Your Extrusion Line
Consistent Pipe Geometry at Low Speeds
The 0.1–3 m/min range is optimized for large-diameter, heavy-wall pipes that require slow, controlled haul-off. Six synchronized servo-driven tracks minimize slippage, ensuring roundness and uniform wall thickness from calibration tank to cutter.
Faster Changeovers, Less Downtime
Pneumatic upper clamping and motorized lower lift simplify diameter transitions within 280–630 mm. Recipe-driven speed settings via the servo controller and real-time feedback via the Dongqi display cut setup time.
Robust Engineering for 24/7 Production
From the 20 mm wall plates to carbon steel chains, every component is specified for high load and long service life, reducing maintenance intervals and stabilizing production costs.
Customer Value: Reliability, Quality, and Control
Production Stability
Users report steady traction with reduced surface scuffing on 400–630 mm pipes, lowering rework and scrap rates in infrastructure-grade products.
Energy-Aware Performance
Servo control delivers torque on demand, improving efficiency at low speeds and during start/stop cycles commonly seen in large-pipe extrusion.
Maintenance-Friendly Design
Accessible frames, standardized components (Schneider/Chint), and durable traction pads simplify routine service and extend component life.
FAQs
Can this haul-off integrate with existing extrusion lines?
Yes. Center height is customized per buyer, and the servo controller accepts standard signals for line synchronization.
Which materials are supported?
Optimized for PVC and HDPE large-diameter pipes; traction pads and settings can be tailored for CPVC, PP, and composite pipes.
What ensures traction without surface damage?
1″ wear-resistant rubber pads with large contact area, combined with precise servo torque control and pneumatic/motorized clamping.
