Drop-type trailer product parameters mainly include the following aspects:
Basic Parameters
- External Dimensions: Drop-type semi-trailers are generally 10,000-13,000 mm long, 2,500-2,550 mm wide, and approximately 2,860 mm high. Different models of drop-type trailers have varying dimensions. For example, the SKW9381 drop-type semi-trailer has external dimensions of 13,000 mm × 2,500 mm × 2,860 mm.
- Number of Axles and Wheelbase: Drop-type trailers are commonly available with two or three axles. The wheelbase of a three-axle drop-type trailer may be 6,710 mm + 1,310 mm + 1,310 mm, or 6,560 mm + 1,310 mm + 1,310 mm.
- Gross Mass and Load Capacity: Gross mass is typically between 34,000 kg and 40,000 kg, and load capacity is generally between 31,000 kg and 34,000 kg. - **Curb Weight**: Generally between 5,600 and 6,500 kg.
- Tire Model: Common tire models include 11.00R20 12PR and 12R22.5 12PR.
- Frame: The frame typically utilizes a through-beam structure. Longitudinal beams can be straight or gooseneck. Longitudinal beams are constructed from high-quality steel and welded using automatic buried welding. The frame is shot-peened, and the crossbeams penetrate the longitudinal beams and are welded integrally.
- Sidebar: The sidebar is the primary structure of the cargo area, typically no more than 600 mm in height. It is typically made of high-strength steel, offering excellent durability and protection.
- Suspension: The suspension utilizes a non-independent steel stamped rigid suspension consisting of tandem leaf springs and suspension struts. It offers high rigidity and strength, effectively supporting loads and mitigating impacts.
Performance Parameters
- Brake System: Typically equipped with a pneumatic brake system, it offers reliable braking performance and ensures vehicle safety during driving.
- Steering System: A hydraulic power steering system is used for easy and flexible operation, enhancing driving comfort and safety.
- Speed: The maximum speed generally does not exceed 90 km/h. The specific speed limit is determined based on local traffic regulations and actual vehicle usage.
Other Parameters
- Application: Flatbed trailers have a wide range of uses, primarily for medium- and long-distance transport of medium- and heavy-duty cargo and bulk goods.
- Applicability: Due to their simple structure and high cargo capacity, they have become the preferred choice for medium- and long-distance freight transportation.
