Working Principle
The working principle of the KPW trackless electric flat car is as follows: the battery pack outputs DC power, which is converted by the brushless electrical control assembly to drive the dual AC motors on the rear axle. The motors transmit power through the gearbox to the rubber drive wheels, enabling the flat car to move forward and reverse. For steering, the PLC applies differential speed control to the left and right drive wheels, working in conjunction with the hydraulic slewing support steering mechanism to complete turns. The vehicle employs dual braking methods — dynamic braking and power-off brake application — to ensure safe stopping. Control signals are issued from the handheld wired pendant or wireless remote control, processed by the S7-200 PLC, which then governs the drive motors and steering mechanism.

The KPW trackless electric flat car consists of the following core components:
Frame: Box-beam welded structure with a 6 mm steel plate load-bearing platform.
Steering Wheel Blocks: 4–8 polyurethane solid tires with suspension system.

A: Design & Manufacturing complies with JB/T 6127-92 "Electric Flat Car" and GB 5226.1 "Electrical Safety of Machinery" standards, and safety devices meet relevant industry Specification requirements.
Q: What is the difference between the KPW trackless Electric Flat Car and a rail-mounted Electric Flat Car?
A: The KPW trackless Electric Flat Car requires no Crane Rail installation and travels on rubber wheels on the floor, offering flexible steering and the ability to change routes at any time. A rail-mounted Electric Flat Car requires steel rails to be laid on the floor and runs along a fixed track. Trackless Flat Cars are suitable for handling scenarios with variable routes, while rail-mounted Flat Cars are suitable for heavy-load, fixed-route shuttle transport.
Q: How much does the KPW trackless Electric Flat Car cost?
A: The price of the KPW trackless Electric Flat Car varies by Load Capacity and Table Dimensions. Small 6-ton models are approximately 50,000~100,000 RMB, medium 10~20-ton models are approximately 100,000~200,000 RMB, and large 25~40-ton models are approximately 200,000~500,000 RMB. The exact price depends on non-standard customization requirements. Please contact customer service for a detailed Quotation.
