XINNUO XN-2D7T Full Automatic Hydraulic Double Head Decoiler with Shared Loading Car

The XN-2D7T dual-head uncoiling system is engineered for continuous feeding in high-demand industrial environments. By integrating two independent hydraulic expansion mandrels with a centralized coil loading trolley on a shared track, the system enables seamless material transitions. While one station feeds the line, the operator can use the shared loading car to mount the next 7-ton coil onto the standby mandrel, ensuring a truly non-stop production cycle.

Main Features

• Dual 7-Ton Mandrels: Two heavy-duty uncoiling stations allow for zero-downtime coil replacement, ideal for high-speed automated lines.
• Shared Track Logistics: A single motorized hydraulic loading car services both mandrels on a shared rail system, reducing equipment cost and footprint.
• Precision Hydraulic Expansion: Centralized hydraulic expansion ensures a secure grip on the inner diameter of the coil, preventing slippage during high-speed uncoiling.
• 1200mm Width Capacity: Specifically calibrated to handle standard and narrow steel coils up to 1200mm, providing versatility for various product profiles.
• VFD Speed Control: Integrated with Variable Frequency Drives to ensure smooth startup and synchronized material feeding with the downstream forming machine.

Production Process

Coil Storage → Loading Car Pickup → Horizontal Transport along Shared Track → Lift & Load to Mandrel 1/2 → Hydraulic Expansion → Continuous Uncoiling → Standby Prep on Alternate Head.

Why Choose XN-2D7T

The XINNUO XN-2D7T offers the perfect balance of heavy-duty capacity and logistical efficiency. By sharing a single track and car for two decoilers, it provides the most cost-effective path to non-stop production. It is the ultimate choice for factories looking to upgrade from manual, single-head setups to a professional, automated material handling workflow.

FAQ

Q: Can I load a new coil while the other head is uncoiling? A: Yes, that is the primary advantage. The two heads operate independently, allowing for "Zero-Downtime" preparation.

Q: Does the loading car move automatically? A: The car features motorized movement along the shared track and hydraulic lifting, controlled via the operator console for precise positioning.

Q: What is the maximum width the XN-2D7T can handle? A: This specific model is optimized for a maximum coil width of 1200mm.

Q: Can the mandrel expansion be customized for different inner diameters? A: Our standard range is 480-520mm. For larger IDs, we can provide customized expansion leaves or specialized mandrels.
