2.1 ▣ Single-Deck and Double-Deck Designs
To meet the needs of transporting a wide range of cargo, sluice gate semi-trailers have evolved from a single door design to a variety of models, including single- and double-deck sluice gates, and long and short locking bar sluice gates. Single- and double-deck sluice gate semi-trailers are the most common and long-standing sluice gate structures. Single-deck sluice gate semi-trailers offer easy disassembly, while double-deck sluice gate semi-trailers are more suitable for long-distance transport due to their height advantage. The clearance from the floor to the top of a single-deck sluice gate semi-trailer typically does not exceed 1.8 meters, making sluice gate removal easier.
The design of double-decker slat semi-trailers is characterized by the height from the floor to the top of the slat, which is usually over 1.8 meters. This design not only improves the strength of the slat, but also provides more spacious storage space for cargo. These two types of slat semi-trailers play an important role in long-distance transportation, especially for the transportation of agricultural and sideline products, steel, and bulky light and bulky cargo.
