The frame is designed with a double-layer and embedded structure, which not only ensures sufficient strength and rigidity, but also effectively avoids the risk of tipping over during the transport of workpieces. Moreover, the embedded structure of this application can reduce the overall height of the frame, thereby further reducing the overall height of the flatcar, which is beneficial for the flatcar to pass through some height-restricted areas.

[0046] The specific structure of this application includes:

[0047] The base frame 1 serves as a support and is the base frame of the flatcar. Rollers are subsequently installed to facilitate movement.
