KPT Cable Reel Electric Flat Car for Rail Transport
Product Introduction
The KPT Series Trailing Cable Powered Electric Flat Car (also known as the KPT Series Electric Rail Transfer Cart) has a rated load capacity of 2 to 150 tons. It is powered via a trailing cable system: one end of the cable connects to the ground power supply, while the other end is routed into the cart through a cable clamp device. Its key features include a low table height (450–1200mm) for easy loading and unloading, and low manufacturing costs. It is ideal for heavy-duty material transfer in harsh environments such as high temperature, low temperature, and explosion-proof workshops, as well as for cross-bay transport. Compared to the KPJ Series (which uses a cable reel), the KPT Series offers a simpler structure and a lower overall height.

Working Principle
The KPT Series Cable-Reel Powered Electric Flat Car directly connects an AC 380V trailing cable to the onboard Electrical Control System, which controls the motor's start, stop, forward, reverse, and speed functions. As the cart moves, it pulls the cable along. One end of the cable is connected to the ground power supply, and the other end is routed into the cart's electrical cabinet via a cable clamp device. The cable can be laid on the floor or suspended overhead depending on site conditions. The operating system uses a low-voltage 36V safety control system, and the table surface can be fitted with optional hydraulic or mechanical lifting systems.
Product Structure
- Cart Frame System: Box-type beam structure, offering high load-bearing capacity and resistance to deformation, with low requirements for rail installation precision.
- Power Supply System: Trailing cable with cable clamp device, routing power from the ground supply to the cart's Electrical Control System.
- Drive System: Driven by an AC motor with a power range of 1.5–15 kW, achieving a Travel Speed of 18–25 m/min.

Operating Instructions
- Before operation, inspect the trailing cable for damage or wear, ensure the cable clamps are securely tightened, and confirm the crane rail is clear of obstructions.
- Connect to the 380V power supply, select the travel direction (forward/reverse) via the remote control or operation panel, and verify the travel path is clear.
- When the cable is laid on the floor, the travel distance should be ≤20m to prevent excessive cable friction; when the cable is suspended overhead, medium-to-long-distance transport is possible.
- For applications with slower travel speeds, a cable drag chain can be used to reduce cable wear. Take care to prevent cable entanglement.
- Periodically inspect the cable insulation, cable clamp contact points, motor heat dissipation, and wheel wear. Keep the crane rail clean.

FAQ
Q: What is the difference between the KPT cable-powered electric flat car and the KPJ cable reel-powered model?
A: The KPT model uses a trailing cable system where one end of the cable connects to the power supply and the other end is routed to the flat car via cable clamps. It offers a low table height and the lowest manufacturing cost, but the travel distance is limited (≤100m)—longer distances can cause cable entanglement. The KPJ model uses a cable reel that automatically pays out and retracts the cable, allowing travel distances of up to 200 meters, but with a more complex structure and higher cost.
Q: What environments is the KPT cable-powered electric flat car suitable for?
A: The KPT cable-powered electric flat car is designed for harsh environments, including high-temperature, low-temperature, and explosion-proof conditions. The cable can be laid on the floor or suspended overhead—floor installation supports travel distances of ≤20m, while overhead installation accommodates medium-to-long-distance transport.
Q: What is the price range for different load capacities of the KPT cable-powered electric flat car?
A: Since the manufacturing cost is lower than other power supply options, pricing is relatively economical: small models (2–10t) range from RMB 25,000–70,000, medium models (16–30t) from RMB 70,000–130,000, and large models (40–150t) from RMB 130,000–450,000. Custom non-standard manufacturing is quoted separately. Prices excluding tax and freight need to be confirmed.
