Electric flat car

Electric flat car, also known as electric flat car, level car, trolley, span car, floor crawler, etc., is a kind of rail-based electric transportation vehicle in the factory. First of all, it is a rail-type transportation vehicle. , it is necessary to lay tracks on the ground. The track is generally an I-shaped contact track. Secondly, it is an electric drive vehicle, which runs automatically under the drive of a motor reducer. Thirdly, it is a flatbed vehicle with a flat platform and no cover. Under special circumstances It can also be non-planar but without a car cover. The car body has no steering wheel and can only move forward and backward (even if it turns, it relies on the track to turn)
An electric flat car is an electric rail-based intra-factory transportation vehicle. Also known as trolley and crossover vehicle. It has the advantages of simple structure, convenient use, easy maintenance, large carrying capacity, and less pollution. It is widely used in machine manufacturing and metallurgical factories to cooperate with cranes to transport heavy objects across the span in the workshop. The series of electric flat cars have low height, reinforced table, easy modification and convenient maintenance.
The electric flat car powered by a reel is powered by AC power from a cable reel. The cable drum is a hysteresis coupling type, ensuring that the cable is evenly stressed and not easily damaged. The AC provides power to the metallurgical lifting motor on the flat car, and the motor drives the flat car to run. When the flat car is running, the cable reel automatically rolls up or pays out the cable. Affected by the power supply length of the reel, the maximum running distance is generally less than.
The low-voltage track-powered electric flat car is safe and reliable, not afraid of being hot or smashed, does not hinder cross-transportation, and is easy to realize remote control and automation, making transportation arrangements in the factory very convenient. However, the track construction requirements are relatively high, and the track insulation must be ensured. When the track exceeds a certain running distance, copper bar compensation lines should be added to the track. When the running distance is longer, the number of step-down transformers must be increased.
Battery electric flat car is powered by batteries. The battery provides power to the DC traction motor, and the DC motor drives the flat car to run. Compared with AC motors, DC motors have the advantages of being less prone to burnout, larger starting torque, and stronger overload capability. Running distance is unlimited. Compared with the two series of flat cars, it has greater safety performance and maneuverability flexibility, unlimited running distance, and no insulation requirements for the track, so the construction is convenient and low-cost.
