50 Tons Electric Rail Cart for Safe High-Temperature Molten Iron Handling

Production Challenges

The steel plant's steelmaking workshop originally used forklifts to transport molten iron ladles and ingot molds at high temperatures. Each trip had a load capacity of only 30 tons, requiring multiple trips. Furthermore, internal combustion forklifts had a high failure rate in temperatures above 50℃, short range, and emissions that did not meet environmental standards. This resulted in several instances of delayed transport leading to the cooling and scrapping of molten steel.

Solution

Based on the client's specific needs, Newld customized this 50 ton low voltage railway powered rail transfer cart. It uses a two-phase low-voltage rail power supply, coupled with a step-up transformer and forced-fan cooling system, making it suitable for the high-temperature working environment of the workshop.

The cart body uses a box-girder frame with a rated load capacity of 50 tons, capable of transporting an entire set of ingot molds in one go.

Equipped with a ground control cabinet, wireless remote control, and wired handle dual control modes, supplemented by an emergency stop button and audible and visual warning lights, it creates a comprehensive safety barrier.

Advantages

• High Efficiency and Seamless Operation: Direct rail power supply eliminates the need for frequent charging or battery replacements, enabling seamless 24-hour continuous operation.
• Heavy-Duty And Durable: The box girder structure boasts high rigidity and impact resistance, easily supporting components weighing over 50 tons without deformation even after prolonged use.
• Safe And Environmentally Friendly: Zero exhaust emissions and low operating noise; multiple insulation and explosion proof designs significantly reduce safety risks in high-temperature environments.

Applications

In actual production, the rail transfer cart primarily shuttles between the smelting and casting areas, specifically responsible for the smooth, long distance transfer of high temperature molten iron and heavy ingot molds.

The continuous cooling of the fan system ensures the stability of electrical components. Continuous power supply via low voltage railways allows the transfer cart to move back and forth according to the production rhythm, reducing frequent intervention by manual labor and other lifting equipment. The combination of wireless remote control allows workers to precisely operate the cart from a distance, away from high-temperature radiation areas.
