The Curtain Side Semi Trailer (also known as a curtain trailer) is a versatile enclosed transport vehicle that combines the accessibility of a flatbed with the protection of a dry van. Widely used in logistics, retail, and manufacturing, it transports palletized goods, long items (e.g., steel bars), machinery, and oversized cargo. With a loading capacity of 30–50 tons (customizable), it features reinforced PVC curtains (retractable from front/rear) and van-style rear doors—ensuring weather protection, security, and fast loading/unloading.
• Flexible Access & Loading: The PVC curtains can be retracted from both sides and the rear, allowing side loading (via forklifts) and rear loading (via trucks)—reducing loading time by 30% compared to traditional dry vans. The flatbed design also accommodates oversized cargo (e.g., 18m steel bars) that won’t fit in enclosed trailers.
• Weather & Theft Protection: The reinforced PVC curtains (waterproof, UV-resistant) protect cargo from rain, snow, and dust, while the curtain locks (optional) and rear door latches prevent theft during transit—ideal for high-value goods (e.g., electronics, furniture).
• Durable Structure: The frame uses Q345B carbon steel (high tensile strength) to withstand heavy loads, while the tires (8/12/16/20 units) and axles (2/3/4/5 pcs) are selected for long-distance transport (up to 10,000 km per trip) on highways and rural roads.
• Retail Logistics Pallet Transport: For retail chains (e.g., supermarkets, furniture stores), the trailer transports palletized goods (e.g., food, furniture) from warehouses to stores. The retractable curtains allow forklifts to load/unload pallets quickly, while the PVC material protects goods from rain during last-mile delivery.
• Machinery & Long Item Transport: For manufacturers shipping machinery (e.g., small generators) or long items (e.g., aluminum profiles), the flatbed design fits oversized cargo, while the curtains protect machinery from dust and scratches—ensuring products arrive in perfect condition.
• Logistics Optimization: Our team calculates load distribution (e.g., 30 tons for 3-axle models) to ensure safe transport and provides guidance on curtain maintenance (e.g., cleaning, UV protection). We also offer compatibility checks for forklift loading (e.g., curtain retraction height).
• Customization & After-Sales: We customize axle quantity (2–5 pcs), tire size, and curtain material (e.g., flame-retardant PVC for hazardous goods). Post-purchase, we provide 1-year warranty for the frame and curtains, plus spare curtains (delivered within 72 hours) for urgent replacements.
