Electric flat car, also known as electric plate car, electric level car, trolley, crossover car, electric track car, ground climber, etc., is a type of on-site rail vehicle

Electric transportation vehicles, first and foremost, are track-based vehicles that require the installation of tracks on the ground, typically with an I-beam profile.

Treadway rail; next, it is an electrically driven vehicle, operating automatically under the power of a motor and reducer; again, it is a flatbed truck, with a flat and even surface.

Hatch cover; in special cases, it can also be non-planar without a hatch cover, with the vehicle body lacking a steering wheel, only having forward and reverse directions (even when turning, it relies on the tracks).

This type of vehicle features a simple structure, ease of use, high load-bearing capacity, resistance to dirt and damage, ease of maintenance, and a long service life.

Long features, due to their convenience, robustness, affordability, practicality, and easy cleaning, have become popular for internal factory use and between factories.

Short-range transport vehicle for frequent, point-to-point heavy cargo transport.
