KPX Battery-Powered Electric Flat Car for Rail Transfer
Product Introduction
The KPX Battery-Powered Electric Flat Car (also known as the KPX battery-powered rail transfer cart) has a Rated Load Capacity of 6 to 160 tons. Powered by a battery bank that drives a DC traction motor, its travel distance is not limited. It can operate on S-shaped tracks, curved tracks, and in harsh environments such as explosive, flammable, or high-temperature areas. It requires no track insulation, making installation easy and cost-effective. Compared to the KPJ Cable Reel and KPT cable-powered flat cars, it offers greater safety and operational flexibility, making it the ideal solution for cross-workshop and long-distance transport.

Working Principle
The KPX Battery-Powered Electric Flat Car is powered by a battery bank installed inside the car. The Electrical Control System transmits power to the DC traction motor, which drives the wheels through a Gearbox / Reducer. Commands such as start, stop, forward, reverse, and Speed control are issued via the Remote Control or Operation Panel, and the Electrical Control System relays these commands to the DC motor. Compared to AC motors, the DC motor offers advantages such as resistance to burnout, high starting torque, strong overload capacity, and smooth start/stop without jerking.

Application Scenarios
The KPX series battery-powered electric flat cars are widely used in machinery manufacturing and metallurgical plants for transporting heavy loads across bays in conjunction with overhead cranes. They operate reliably on S-shaped tracks, curved tracks, and in harsh environments such as flammable, explosive, or high-temperature areas. These cars have minimal requirements for track installation, making them ideal for frequent start-stop operations and long-distance transport.

Operating Instructions
- Before operation, check the battery charge level, ensure cable connections are tight, and confirm the track is clear of obstructions.
- Select the travel direction (forward/reverse) via the Remote Control or Operation Panel, and verify the path is clear before starting.
- Lead-acid batteries require regular topping up with distilled water; check that the electrolyte level is above the lower limit.
- Apply Lubricating Oil to the wheels regularly and keep the track clean to ensure smooth operation.
- Maintenance-free batteries should also be kept away from high-temperature environments; if the car is idle for extended periods, recharge periodically to maintain battery health.

FAQ
Q: What is the difference between the KPX battery-powered flat car and the KPJ/KPT models?
A: The KPX uses battery power with a DC motor drive, offering unlimited travel distance and suitability for S-shaped/curved tracks and explosion-proof environments. It provides greater maneuverability and flexibility but requires periodic recharging and maintenance. The KPJ is powered via a Cable Reel, while the KPT uses a trailing cable — both have cable length limitations but do not require recharging.
Q: What is the battery life of the KPX battery-powered flat car?
A: It is equipped with tubular positive plate traction batteries, with capacities ranging from 180Ah to 500Ah+ depending on usage intensity. An optional automatic charger enables Unattended Operation charging, and maintenance-free, lithium, and explosion-proof battery options are available.
Q: What is the price range for different load capacities of the KPX battery-powered flat car?
A: Due to the higher cost of the battery pack: light-duty models (6–16t) range from 50,000–120,000 RMB, medium-duty models (25–60t) from 120,000–250,000 RMB, and heavy-duty models (100–160t+) from 250,000–600,000 RMB. Custom Non-Standard Manufacturing and special battery configurations are quoted separately; prices include tax and freight upon confirmation.
