The Cable Powered Die Rail Cart for Steel Mill is a heavy-duty electric transfer vehicle designed for safe and efficient die or mold transportation within steel production and heavy manufacturing environments.
Powered by a retractable cable reel system, the cart ensures a continuous and stable AC power supply, providing reliable performance for long-duration and high-load operations.

With a rugged steel frame, precision control, and strong drive system, this rail cart is ideal for moving steel dies, casting molds, or large tools between workshops, presses, and assembly areas in steel mills and metalworking plants.

Working Principle

The cable-powered rail cart operates via a cable reel (drum) power system:

• The cart receives 380V AC power through an industrial-grade cable reel, which automatically winds or unwinds as the cart moves.

• The supplied current drives the electric traction motor through the control cabinet, ensuring stable torque and smooth acceleration.

• This design enables continuous operation without downtime, making it highly efficient for production lines that require frequent die handling.

Key Features

Reliable Cable Power Supply

• Continuous and efficient AC power via automatic cable reel.

• No need for batteries, ensuring uninterrupted operation.

• Perfect for fixed-route transfer tasks within steel mill environments.

Strong Load Capacity

• Engineered to handle heavy molds, dies, or steel components up to 300 tons.

• Reinforced welded steel frame prevents deformation and ensures long lifespan.

• Stable rail guidance system supports heavy-duty workshop operation.

Smooth Drive and Control System

• Equipped with AC drive motor and variable frequency drive (VFD) for smooth speed control.

• Soft start and stop reduce mechanical shock and protect die integrity.

• Multiple control options — wired pendant, wireless remote, or PLC automation.

Safety and Reliability

• Emergency stop switches, warning alarms, and limit sensors included.

• Cable tension protection prevents cable wear or accidental disconnection.

• Optional infrared anti-collision sensors enhance operational safety in busy areas.
