The 5 Ton Interbay Low Voltage Rail Driven Coil Transfer Trolley is a safe, efficient, and energy-saving rail-guided transport vehicle specially designed for transferring steel coils, aluminum rolls, or other cylindrical materials between production bays (interbay transport).
Powered directly by low-voltage rail electricity, this trolley eliminates the need for cables or batteries, offering continuous operation, smooth movement, and high reliability for industrial environments.

It is widely applied in steel plants, rolling mills, aluminum factories, and metal processing workshops, where precise and frequent coil handling is required.

Working Principle

The trolley operates using a low-voltage power supply system (36V / 48V / 72V) integrated into the rails.
A special power pickup device (carbon brush or conductive shoe) collects the current from the rails and feeds it to the onboard control system and traction motors.
The motors then drive the wheels to move the trolley smoothly along the rails — achieving safe, stable, and automatic power delivery without cables or external connections.

This KPD series low-voltage rail system is ideal for medium-to-long distance operations (typically ≤200 meters).
