Product Description

Double Cone Uncoiler | Heavy-Duty Coil Handling Equipment | Max Load 30 Tons

Our Double Cone Uncoiler is designed for stable and efficient coil loading, supporting up to 30 tons. Ideal for heavy-duty steel coil processing lines. Inquire now for custom solutions.

The Double Cone Uncoiler is an essential coil handling device designed for high-capacity steel coil processing lines. With a maximum load capacity of 15 tons, this uncoiler is ideal for heavy-duty applications requiring precise centering, secure coil support, and seamless feeding into the production line.

Key Features

Max Coil Weight: 30 Tons
Coil Inner Diameter Range: 508mm / 610mm
Coil Width: Up to 1600mm (customizable)
Hydraulic expansion & centering system
Motorized rotation for smooth decoiling
Stable base structure with anti-slip support

Why Choose a Double Cone Uncoiler?

Precise Centering: Automatically aligns coils for stable feeding.
Time-Saving: Compared to single-arm or double-head uncoilers, double cone design requires less coil changeover time.
High Stability: Prevents coil tilting or slipping during operation.
Compatible: Can be integrated with slitting lines, cut-to-length lines, and ERW tube mills.

Typical Applications

This equipment is widely used in:

Steel Tube Mill Lines
Cold Roll Forming Lines
Slitting and Cut-to-Length Lines
Heavy Coil Storage and Unwinding Systems

Customization Available

We offer tailored solutions based on coil size, loading system, automation level, and integration needs. Contact us to discuss your specific requirements.

3. Workflow Overview

The Double Cone Uncoiler plays a crucial role in the initial stage of coil processing. It ensures smooth and stable unwinding of heavy steel coils, feeding material into subsequent equipment such as straighteners, feeders, slitting machines, or tube mill formers. Below is a typical workflow:
1. Step 1: Coil Loading – The coil is loaded onto the double cone using a crane or coil car.
2. Step 2: Hydraulic Expansion – The cones expand inward to securely center and grip the coil core.
3. Step 3: Coil Rotation – Motorized rotation begins to slowly uncoil the strip under controlled tension.
4. Step 4: Material Guiding – The strip is guided into a pinch roll or straightening unit for alignment and leveling.
5. Step 5: Continuous Feeding – The strip enters the main processing unit (e.g., slitter, tube forming machine, etc.).
This workflow ensures continuous, stable material feeding with minimal operator intervention and high efficiency.

Double Cone Uncoiler FAQS

What is the maximum coil weight the Double Cone Uncoiler can handle?

The standard model supports a maximum load of 35 tons. Higher capacities can be customized upon request.

What coil inner diameters are supported?

The uncoiler typically supports 508mm and 610mm inner diameters. Other sizes are available upon customization.

Can the uncoiler be integrated into an automated production line?

Yes. The Double Cone Uncoiler can be seamlessly integrated with straighteners, feeders, slitting machines, and tube mills to form a fully automated production line. We also offer complete turnkey solutions.

What are the differences between a Double Cone Uncoiler and a Single Arm or Double Head Uncoiler?

Compared to conventional designs, the Double Cone Uncoiler provides superior centering, load stability, and faster coil changeovers, making it ideal for continuous operation and heavy-duty coil processing.

What are the power and hydraulic specifications?

The equipment is equipped with a motorized decoiling system and a hydraulic expansion mechanism. Power specifications can be adapted to local standards (e.g., 380V / 50Hz).
