The sides and ends are constructed using a frame structure combined with side panels, while the base is made of skid wood. Framed wooden crates are large wooden crates; their maximum internal weight and maximum external dimensions are determined based on typical transportation conditions. Generally, the external length of a framed wooden crate is less than 12m, the external width is less than 3.5m, and the external height is less than 3.5m, with the internal weight ranging from 500-20000kg. These crates are primarily used for packaging large machinery products and can also be used to consolidate small items. Framed wooden crates consist of a base, sides, ends, and a top. The structural differences between them are: Framed wooden crates have upright panels; the panels are on the outside, while the entire frame is located inside the crate. When assembling a framed wooden crate, the two sides are first attached to the base and the other two sides, and finally the top is attached. Both rely on the base for load-bearing, but framed wooden crates have additional frame structures on the ends and sides compared to skid crates. It is precisely because of these frame structures that framed wooden crates can withstand much greater loads than skid crates.
Framed wooden crates can be classified into two types according to their structure: Type I (internal frame crates): the frame components are on the inside of the crate panels, suitable for general contents; and Type II (external frame crates): the frame structure is on the outside of the crate panels, suitable for contents that are integral along their length and have sufficient rigidity. Their basic design specifications consider commonly anticipated transportation, loading and unloading, and storage conditions.
