Manual decoiler

Manual Decoiler – Reliable Metal Coil Handling Solution for Your Production Line

When you're looking for a cost-effective way to feed metal coils into your roll forming or stamping line, our Manual decoiler from Cangzhou Zhongtuo delivers enterprise-grade reliability without the complexity of motorized systems. Outlined with a stacking capacity of 5-10 tons and an flexible inward distance across run of 450-550mm, this passive-type uncoiler highlights a basic yet vigorous structure. It's prepared with a manual alteration wheel and exactness brake framework, permitting you to control fabric stream easily. Your coil remains safely mounted whereas downstream hardware pulls the fabric easily, anticipating surface harm and perilous coil collapse that torment floor-based loosening up methods.

What Makes Our Manual Decoiler Different?

You require hardware that works the minute it arrives. Our decoiler works on a mechanical drag-brake guideline that gives you moment pressure control.

No power required. No pressure-driven pumps. Fair immaculate mechanical reliability.

The contact brake framework lets you alter back-tension with a basic handwheel. This anticipates fabric coasting when your line stops abruptly. Your administrators will appreciate how rapidly they can dial in the culminate pressure for distinctive coil weights and materials.

The extended mandrel plan obliges standard process coils. A hand-crank instrument extends the portions to grasp your coil's inward distance across safely. Heavy-duty decreased roller orientation handle spiral loads without normal upkeep needs.

Technical Specifications

Where You'll Use This Equipment

On-Site Construction Projects

When you're running portable roof panel machines at job sites, reliable power isn't always available. This decoiler becomes your stable pay-off station for color-coated steel or aluminum coils. It handles uneven ground conditions better than motorized units that require level installation.

Metal Stamping Workshops

Your progressive dies need consistent strip tension. The adjustable brake keeps material taut as it feeds into punch presses. This eliminates the jerking motion that throws off pitch accuracy when producing brackets, hinges, or electrical components.

HVAC Ductwork Fabrication

Galvanized steel processing involves frequent stops and starts. The friction brake stops mandrel rotation instantly when your shear engages. You won't have loose loops of sheet metal piling up on your floor anymore.

Light Gauge Roll Forming

Whether you're making door frames, ceiling tracks, or shelving systems, smooth material entry is critical. This Manual decoiler provides the controlled rotation axis that prevents tangling and scratching during the forming process.

Why Choose Zhongtuo for Your Decoiling Needs?

Since 2014, we've specialized in cold roll forming machinery and auxiliary equipment. Our national-level high-tech enterprise status reflects our commitment to innovation and quality.

We hold ISO 9001, CE, and CAS certifications. These aren't just badges—they represent our rigorous manufacturing standards and global compliance.

Our partnership with Yanshan University's National Cold Rolled Strip Equipment Engineering Research Center brings cutting-edge research into every product we make. Graduate researchers work directly in our factory, optimizing designs through finite element analysis and AI-assisted simulation.

You'll benefit from over a decade of export experience to 150+ countries. We understand regional requirements and provide tailored solutions that match both international standards and local preferences.

Quality That Protects Your Investment

We inspect every critical component before it leaves our facility.

Mandrel concentricity stays within ±0.5mm runout tolerance. This precision prevents coil bouncing that creates material ripples in your finished product.

All welds undergo penetrant testing. The connection between the upright pillar and base must withstand the moment arm stress of a fully loaded coil without failure.

Brake torque gets tested from full release to full lock. You receive uniform resistance across the entire adjustment range—no sticking or slipping.

Static load testing uses 1.25x rated capacity for four hours. We measure spindle deflection to ensure zero permanent deformation under extreme conditions.

Frequently Asked Questions

How do I keep the coil from spinning out of control when the line stops?

The adjustable friction drag brake handles this perfectly. Tighten the tension bolt on the side until you feel resistance. You want enough friction to stop the coil's rotational inertia, but not so much that it strains your roll former's pulling motor. Start with moderate tension and adjust based on your coil weight.

Can this handle coils with different inner diameters?

Absolutely. The standard expansion range covers 450-550mm. If you're working with larger IDs up to 610mm, we offer A-frame extension plates that bolt onto the existing mandrel segments. The hand-crank system adjusts quickly between different coil sizes.

What's the maintenance schedule for this equipment?

The tapered roller bearings carry massive loads even though the machine is passive. Grease them every 3-6 months depending on your usage volume. This simple maintenance step prevents seizing, which causes most failures in older decoilers. Beyond that, periodically check brake pad wear and ensure all mounting bolts stay tight.

Will the decoiler tip over with heavy coils?

Stability depends on proper installation. Bolt the base to your floor using the mounting holes. If you're using it on job sites without bolting capability, the base footprint must be wide enough, or add counter-weights to the rear legs. Never exceed the 10-ton maximum capacity.

How does manual expansion compare to hydraulic systems?

You turn a hand-crank that pushes a tapered wedge inside the shaft. This mechanically expands the leaf segments to grip your coil. Hydraulic expansion uses a cylinder and requires a power pack. The manual system keeps the unit portable, eliminates maintenance on hydraulic components, and removes the risk of fluid leaks in your facility.

What materials can I process with this decoiler?

It handles all standard metal coils—cold-rolled steel, galvanized steel, color-coated steel (PPGI), aluminum, copper, and stainless steel. The brake system adjusts for different material weights and friction characteristics. Just ensure your coil weight stays within the 5-10 ton capacity range.
