The Low Voltage Rail Transfer Trolley is a high-efficiency, rail-guided electric transport vehicle designed for industrial material handling across production lines, workshops, and warehouses.
It operates using a low-voltage power supply system integrated into the rails, providing safe, continuous, and reliable power for long-term use without the need for batteries or cables.

This trolley is ideal for steel mills, machinery plants, automobile manufacturing, and assembly workshops, offering a clean, durable, and cost-effective material transport solution for heavy loads.

Working Principle

The Low Voltage Rail Transfer Trolley draws power directly from the rails, typically at 36V / 48V / 72V AC, using specialized conductive rails and pickup devices (carbon brushes or sliding shoes).
The collected current is converted through an onboard control system and delivered to AC traction motors that drive the trolley along the rails.
This design ensures safe, continuous power transmission with no cable drag or charging downtime, making it ideal for long-distance and high-frequency use.
