The rail flat car is an electric rail transport vehicle to solve the product transportation between the spans。 Also known as cross flat cars, trolley, electric flat cars。 The utility model has the advantages of simple structure, convenient use, easy maintenance, large carrying capacity and less pollution。 Widely used in machinery manufacturing and metallurgical plants, as the workshop with cranes to transport heavy objects across the use of different power supply methods can be divided into towline power supply rail flat car, cable drum power supply rail flat car, battery power supply rail flat car。
Towed cable power supply rail flat car
One end of the cable is connected to the ground power supply, and the control box is introduced through the cable pulley and the traction wire rope, then the YZ motor on the flat car is provided with power to drive the flat car. But the running distance can not be too long, generally can not exceed 50m, too long is easy to wind the cable. Because the starting current flowing through the track is very large (up to 1000A), there is a great voltage drop at the end of the track, which makes it difficult to start the single-phase capacitor motor. So the flat car load tonnage is 50 tons, and the load is more than 50 tons when the three-phase 36V low-voltage rail power supply, lifting metallurgical motor.
Cable drum, power supply rail flat car
Receive and discharge cable in the form of reel, 380V AC power supply, cable reel for hysteresis coupling, to ensure that the cable force uniform and not easy to pull out. AC 380V to flat cars, AC motor provides power, motor drives flat cars to run. When the flat car runs, the cable drum automatically rolls up or releases the cable, which is affected by the power supply length of the coil drum, and the general operating distance is less than 200 m.
