The frame container is a special type of container without a roof and on both sides. It is loaded and unloaded through the sides, effectively solving the transportation problems of extremely long, wide and heavy goods. Its bottom plate is designed with thickened steel, with a load capacity of up to 60 tons, capable of carrying heavy goods such as construction machinery, coil steel, and raw steel. Compared to the platform container, it has a vertical plug structure and supports the operation of standard container lifting equipment, combining the standardized advantages of container transportation with the flexibility of bulk cargo transportation.
