Safety of Transfer Carts Powered by Low-Voltage Rails

Ensuring proper insulation for transfer carts powered by rails is crucial for operational safety and stability.

1. Rail Material Selection

The choice of rail material is critical. Special alloys with excellent insulation properties or specially treated steel should be used to reduce the risk of electrical conduction from the foundation.

2. Track Laying and Insulation

When laying the track, high-quality insulating rubber pads should be placed between the track and the ground foundation to prevent potential current conduction between the track and the earth. The thickness and insulation parameters of the rubber pads should be carefully selected to match the voltage and power specifications of the transfer cart.

3. Collector Insulation

The collector, which directly contacts the track to draw power, is a key component. It is essential to use high-strength, well-insulated engineering plastics to encase the collector, with only the conductive brushes exposed to the track. This ensures that the current does not leak. The connection between the body and the collector should also be covered with an insulating rubber tube to provide full protection and prevent damage or leakage.

4. Wheel Insulation

The wheels of rail transfer carts are typically made of insulating rubber. This not only ensures smooth operation but also prevents the wheels from becoming electrified. In harsh environments, such as areas with high humidity or dust, it is important to regularly clean and inspect the insulating parts. The insulation performance should also be checked using a professional insulation resistance tester. If the insulation resistance drops, damaged parts should be replaced immediately to ensure the transfer cart remains in a safe, insulated state and operates smoothly and efficiently.
