Working Principle:
Two‑Phase Low‑Voltage Rail Power Supply
220V AC power is connected to a step‑down transformer and reduced to 36V safe voltage, which is then supplied to the rails. The collector shoes mounted under the cart pick up power by contacting the rails. The alternating current goes through a rectifier and is converted into direct current to drive the cart's motor and electrical cabinet, allowing the cart to operate.
Three‑Phase Low‑Voltage Rail Power Supply
380V high‑voltage power is connected to a step‑down transformer and reduced to 36V, then transmitted to the rails. Power is collected by the collector shoes on the cart. Since the cart uses an AC motor, the current does not need rectification ,through the step-up transformer, it is raised to 380 volts. directly powers the motor and electrical cabinet.
Difference Between Two Systems
Carts using two‑phase power are equipped with DC motors and require a rectifier to convert AC to DC.Carts using three‑phase power use AC motors and can run directly on low‑voltage AC without rectification.
Safety
Safety is always a major concern for customers. Many ask whether low‑voltage rail power supply is safe and whether electric shock may occur. In practice, such accidents have never happened. Modern rail laying and insulation technologies are highly mature with multiple layers of protection, so customers can use the system with confidence.
Rail Installation
Before installation, prepare rails, insulation pressure plates, insulation pads, insulation paint, and other accessories.A professional team can complete the installation according to the foundation construction drawing.
The most important step after installation is testing. Use a multimeter to measure the voltage and insulation performance of the rail system. The installation is completed only after all parameters are qualified.
Load Capacity, Dimensions and Gauge
The load capacity of the DDG Rail Powered Transfer Cart ranges from 1 ton to 1500 tons, all customizable.Platform dimensions are custom designed based on cargo size and load weight.
Rail gauge can be customized to match your existing track gauge.If there is no existing rail system at your site, we can provide a suitable gauge design and complete construction drawings.
Service Life and Maintenance
The service life of the Rail Powered Transfer Cart is no less than 15 years. Its long lifespan is guaranteed by heavy‑duty profiles and high‑strength structural design. Rail-mounted carts generally have an even longer service life, making them a worthwhile long-term investment.
Daily Maintenance
Keep the rail system clean and free of conductive debris.
Do not operate in accumulated rainwater.
The cart itself requires little extra maintenance.
Regularly lubricate the motor and gears with lubricating oil.
No dedicated maintenance personnel is required.
