XINNUO XN-2D7T Full Automatic Hydraulic Double Head Decoiler with Shared Loading Car
The XINNUO XN-2D7T is a high-performance material handling system designed for high-capacity industrial production lines. Featuring dual 7-ton hydraulic heads, this system allows for alternate uncoiling and preparation, effectively eliminating machine idle time during coil changes. Both stations share a precision-aligned rail track and a heavy-duty hydraulic loading car, optimizing floor space while ensuring safe and efficient handling of coils up to 1200mm in width. This integrated "Twin-Head" solution is the industry standard for manufacturers seeking to maximize the OEE (Overall Equipment Effectiveness) of their roll forming or stamping operations.
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.
