Ground Rail Coil Transfer Car (No Foundation Pit Required)

Ground Rail Coil Transfer Car for ERW Tube Mill

The Ground Rail Coil Transfer Car is an efficient coil handling solution designed for steel coil transportation in ERW tube mills, roll forming lines, slitting lines, and other coil processing systems. Unlike traditional underground coil cars that require deep foundation pits and civil construction work, this model operates on surface-mounted rails, eliminating the need for excavation while maintaining reliable coil transfer performance.

This design is especially suitable for existing factories, rental workshops, or facilities where foundation excavation is difficult, expensive, or impossible. The transfer car moves steel coils from the storage area to the decoiler position quickly, safely, and efficiently, reducing installation costs and shortening project lead times.

Key Features

No Foundation Pit Required

Traditional coil cars typically travel in an underground pit between the coil storage area and the uncoiler. This requires extensive excavation, concrete work, drainage systems, and extended installation time.

The Ground Rail Coil Transfer Car operates entirely above ground on steel rails, eliminating the need for pit construction and significantly reducing civil engineering costs.

Easy Installation

The rail system can be installed directly on the workshop floor with minimal site preparation. This allows faster commissioning and reduced production downtime.

Suitable for Existing Plants

Many existing production facilities do not have sufficient floor depth or structural conditions for pit excavation. The ground rail design provides an ideal retrofit solution.

Safe Coil Handling

The car is designed to securely support and transport steel coils from the loading area to the decoiler, reducing manual handling and improving workplace safety.

Flexible Integration

Compatible with:

• ERW Tube Mills

• Steel Pipe Production Lines

• Roll Forming Machines

• Slitting Lines

• Cut-to-Length Lines

• Steel Coil Processing Systems

Working Principle

The steel coil is loaded onto the transfer car using an overhead crane, forklift, or coil lifting device.

After loading, the transfer car travels along the ground-mounted rails toward the decoiler or uncoiler station. Once positioned, the coil can be transferred onto the mandrel of the uncoiler through coordinated lifting or positioning mechanisms, depending on the production line configuration.

The entire process improves coil loading efficiency and reduces equipment downtime.

Frequently Asked Questions

Does this coil car require a foundation pit?

No. The transfer car operates on above-ground rails and does not require underground excavation.

Can it replace a traditional pit-type coil car?

In many applications, yes. It provides the same basic coil transportation function while reducing installation complexity and construction costs.

What coil weight can it handle?

The capacity depends on customer requirements. Typical designs range from 5 tons to 30 tons or more.

Is it suitable for existing factories?

Yes. This design is particularly suitable for existing workshops where excavation is not feasible.

Can the rail length be customized?

Yes. Rail length can be designed according to the customer's plant layout and production line configuration.

Can the system be integrated with automatic loading equipment?

Yes. The transfer car can be integrated with decoilers, coil loading arms, hydraulic lifting systems, and automated material handling systems.
