Steel Bar Coil Decoiler

A Steel Bar Coil Decoiler (also known as a coil cradle) is an essential material-handling device designed for efficient storage and dispensing of coiled reinforcement bars (rebar). Widely used in construction sites, steel processing workshops, and fabrication plants, this equipment ensures smooth unwinding, reduces manual labor, and prevents coil tangling.

Key Components

1. Rotating Frame

Constructed with a steel-welded central shaft, support arms, and sturdy base.
Available in two main types:
- Vertical Type: Common and space-efficient.
- Horizontal Type: Ideal for limited space installations.
Features 360° free-spinning rotation with low-friction bearings or bushings.

2. Coil Support Platform

Load capacity ranges from 1 to 5 tons, adjustable to fit coils from Φ6mm to Φ16mm diameter rebar.
Equipped with rubber lining or rollers to prevent coil surface abrasion.

3. Braking System (Optional)

Manual brake or automatic damping options to control unwinding speed and prevent over-spinning.

4. Mobile Base (Optional)

Comes with locking casters for easy movement and secure positioning.

Design Considerations

Load & Stability: Proper alignment of coil’s center of gravity with rotational axis to prevent tipping; base reinforcement for heavy coils.
Smooth Rotation: Use of sealed bearings such as tapered roller bearings to minimize friction and avoid excessive free spinning that risks coil entanglement.
Safety Features: Includes guard shields over rotating parts complying with OSHA/CE standards and anti-springback bars to prevent recoil injuries.

Operational Guidelines

Loading the Coil: Utilize cranes or forklifts to center and secure the coil on the decoiler stand to prevent slippage.
Unwinding Process: Pull rebar evenly at a 5°–10° angle relative to coil tangent; wear protective gloves and maintain safe distance from rotating parts.
Maintenance: Regular lubrication of bearings (recommended monthly with grease) and periodic inspection for structural cracks or rust.

Applications & Benefits

Widely applied in construction projects, steel fabrication plants, and rebar processing workshops.
Improves efficiency by enabling continuous, smooth unwinding of rebar coils.
Minimizes manual labor and reduces risks of coil damage and tangling.
Designed for durability and safety to meet industrial standards.
