KPJ Electric Flat Car with Cable Reel Power Supply
Product Introduction
The KPJ series cable reel powered electric flat car (also known as cable reel rail transfer cart) has a rated load capacity of 1 to 150 tons and a travel speed of 20m/min. It is a rail-mounted transport vehicle designed for heavy-duty material transfer in applications such as cross-workshop transport, paint booths, and heat treatment facilities. Powered by a spring-type cable reel, the cart draws power through a cable that is automatically paid out and retracted by the reel assembly mounted on the cart, enabling a travel distance of up to 200 meters. It features a compact structure, simple operation, and stable cornering.

Working Principle
The KPJ series cable reel powered electric flat car receives 380V power through a cable that is paid out and retracted by the reel assembly mounted on the cart. The reel assembly is positioned beneath the flat car, and the AC control system governs the motor's start, stop, forward, reverse, and speed control functions. The operating system uses a safe low voltage of 36V for control. The table surface can be fitted with hydraulic or mechanical lifting systems as required, enabling automated remote control.

Application Scenarios
KPJ cable reel-powered electric flat cars are widely used in paint booths, sandblasting rooms, paint baking rooms, heat treatment facilities, and various harsh environments involving high temperatures, high humidity, or explosion-proof requirements. They can serve as electric rail transfer cars or electric rail tractors, enabling automatic coupling between the tractor and unpowered cars. These cars are ideal for cross-bay material handling and heavy-duty load transfer within workshops.

FAQ
Q: What standards does the KPJ cable reel-powered electric flat car comply with?
A: The design & manufacturing of the KPJ cable reel-powered electric flat car follows the JB/T 6127-92 "Electric Flat Car" machinery industry standard, and electrical safety complies with GB 5226.1 "Electrical Safety of Machinery."
Q: What is the difference between KPJ cable reel power supply and KPX battery power supply?
A: The KPJ model draws power from an external source via the cable reel, with no operating time limit, making it suitable for long-distance, high-frequency operations (up to 200 meters). The KPX model uses battery power, requires no cable, and offers greater flexibility for applications involving frequent movement across different areas, but is limited by battery life.
Q: What is the price range for KPJ cable reel-powered electric flat cars by load capacity?
A: Prices vary significantly by load capacity: small models (1–10t) range from RMB 30,000–80,000; medium models (16–30t) from RMB 80,000–150,000; large models (40–150t) from RMB 150,000–500,000. Custom non-standard manufacturing is quoted separately. Tax-inclusive and freight-inclusive pricing to be confirmed.
