The single arm uncoiler is an efficient, compact, and space-saving device designed for uncoiling steel coils in tube mills and other metalworking lines. Compared to double-head uncoilers, the single arm uncoiler offers a larger load capacity of up to 15 tons, making it ideal for handling heavier coils. This design ensures greater stability and efficiency when processing heavy steel coils.
-
Higher Load Capacity
Compared to double-head uncoilers, the single-arm uncoiler has a higher load capacity, capable of handling coils weighing up to 15 tons. It offers stable uncoiling support for both light and heavy coils, ideal for high-demand production environments.
-
Quick Coil Change System
The single-arm uncoiler supports a quick coil change system, allowing operators to switch to a new coil quickly when the current coil runs out, ensuring no downtime on the production line. Coil change time is typically within 2 minutes.
-
Hydraulic Expansion and Retraction
The hydraulic system allows the mandrel to quickly expand and contract, accommodating different coil sizes. This feature reduces manual operations and improves production efficiency.
-
Tension Control
An optional tension control system maintains constant tension during uncoiling. The system monitors the tension in real time and adjusts it automatically for stable production.
-
Multiple Control Options
Manual operation mode is available for small-batch production or simple applications. An optional PLC control system allows for automated control, data collection, and production line integration, improving automation and production efficiency.
-
High Adaptability
The single-arm uncoiler can handle coils of various thicknesses and widths, and is compatible with carbon steel, stainless steel, galvanized steel, and other materials, meeting a wide range

- 3. Workflow Overview
-
-
Mandrel
Designed with a single-arm structure, the mandrel uses a hydraulic expansion system to securely hold the coil. It can handle larger coil IDs and heavier coils, with a maximum load capacity of 15 tons, making it ideal for high-load production lines.
-
Hydraulic System
The hydraulic system is used for mandrel expansion and retraction, providing strong support to keep even heavy coils securely in place.
-
Motor
The motor drives the mandrel to rotate the coil, with adjustable motor power to accommodate different material uncoiling requirements.
-
Tension Control Device
The tension control system adjusts the tension of the steel strip, ensuring stable feeding into the production line without over-tightening or loosening.
-
Guide Device
Keeps the steel strip aligned with the production line during uncoiling, preventing the strip from deviating from the track.
-
Control System
Offers both manual and automatic operation modes. An optional PLC control system enables automatic coil change, tension adjustment, and production line linkage for improved automation.
-
Support Frame
The frame is made of steel structure to ensure stability and robustness during operation. Adjustable legs are provided for adaptability to different production environments.
