High Load Capacity & Robust Build: Engineered with a heavy-duty welded steel frame to safely support and unwind massive steel coils, making it ideal for demanding industrial roll forming and slitting lines.
Precise Hydraulic Tension Control: Features an advanced hydraulic braking system that applies consistent and adjustable back tension, preventing material sagging and eliminating surface scratches during unwinding.
Effortless Coil Loading & Expanding: Equipped with a hydraulic expanding mandrel and optional lifting dolly/support arms, allowing operators to load, center, and secure heavy coils quickly and safely.
Smooth & Adjustable Unwinding: Driven by an AC motor with a frequency converter, the decoiler provides highly stable rotational torque and allows precise speed adjustment to match the downstream roll forming line.
Intelligent Automation & Safety: Integrates seamlessly with PLC control systems and features motorized hold-down arms and safety brakes to prevent coil rollback, ensuring continuous, automated, and safe material feeding.
The Hydraulic Decoiler Machine is a critical auxiliary equipment designed to securely hold, support, and systematically unwind large, heavy coils of metal strip in continuous roll forming, slitting, and cut-to-length lines. Unlike simpler mechanical versions, this heavy-duty uncoiler utilizes a pressurized hydraulic system to perform its core functions, offering unparalleled control and power. The core operation involves loading the coil onto the decoiler's mandrel, which then expands hydraulically to grip the coil from the inside. A critical component, the hydraulic brake, applies consistent and adjustable back tension to the material. This tension prevents the coil from unraveling uncontrollably, ensures a tight and stable feed into the straightener or roll former, and protects delicate pre-painted surfaces from damage. Built with high-quality 45# steel shafts, forged rollers, and robust hydraulic cylinders, this machine guarantees long-term durability and minimal maintenance.
