Transportation

  1. Bulk cargo, without dismantling any components, shipped as a whole. Advantage: Moderate price, complete shipment, but the product is susceptible to seawater erosion.
  2. Container transportation is cheap and can effectively protect machinery during transportation. But to disassemble the machinery,you need to assemble it yourself after receiving the goods.
  3. Frame container transportation is similar to container transportation, but frame containers can transport ultra-high machinery.
  4. Ro-ro transportation. The product is in the cargo hold and has strong protection, but the price is expensive.

FAQ

A:

A curtain side semi trailer, also known as a tarpaulin or curtain-sided trailer, is designed for transporting palletized goods, packaged cargo, consumer products, and light industrial materials. It combines the flexibility of a flatbed trailer with the protection of an enclosed box, allowing fast side loading while keeping cargo protected from weather conditions.

A:

Compared to a fully enclosed box trailer, a curtain side trailer offers significantly faster loading and unloading because cargo can be accessed from both sides using sliding curtains. It also provides more flexibility for oversized or irregularly shaped goods, while still offering protection from rain, wind, and dust during transportation.

A:

Curtain side semi trailers are widely used for logistics distribution, FMCG products, electronics, beverages, building materials, and general freight. They are especially suitable for warehouse-to-warehouse transport where efficiency and quick turnaround time are critical.

A:

Yes. Curtain side semi trailers can be customized based on operational needs. Options include axle configuration, trailer length, roof design (fixed or sliding), curtain material thickness, load-bearing capacity, suspension type, and rear door structure. Custom branding and color printing on curtains are also available for fleet identity.

A:

Cargo security in a curtain side trailer is ensured through reinforced side posts, tensioned curtain systems, and optional locking mechanisms. While it allows easy side access, the curtain system is designed to remain tightly secured during transit, preventing movement, dust exposure, and light weather impact.
