The tarpaulin (side curtain cloth) of the side curtain trailer is not just a "piece of cloth", but one of the core components of the vehicle's functional and safety system. Its role can be summarized as "six protections, two conveniences, and one added value":
1. Six protections
• Rain and dustproof: high-strength PVC coated cloth, seamless heat-sealed throughout, combined with bottom pressure strips and side curtain tensioners, to form a fully enclosed barrier, zero penetration of goods in rainstorm and dusty environments.
• Sun protection and heat insulation: dark or silver-gray coating reflects ultraviolet rays, and the temperature in the car can be 8-12 ℃ lower than that of the bare car, protecting cartons and plastic parts that are sensitive to temperature rise.
• Anti-theft and anti-destruction: stainless steel wire rope or aramid fiber is embedded in the inner side of the curtain, which cannot be cut by scissors within 30 seconds; a one-time RFID lead seal is attached to the outside, and an alarm will be sounded if it is opened illegally.
• Anti-lateral impact: the curtain and the hidden column form a "flexible + rigid" composite wall, which can reduce the displacement of goods by about 30% in the rollover test and reduce the risk of overturning.
2. Two conveniences
• Convenient loading and unloading: The entire curtain on one or both sides can be completely rolled up to the end within 30 seconds, and the forklift can operate on three sides at the same time, and the loading and unloading efficiency is 70% higher than that of a van.
• Convenient maintenance: The curtain has a modular slide rail design, and a single damaged curtain can be pulled out and replaced within 5 minutes without returning to the factory, and the vehicle can continue to operate.
3. One value-added
• Advertising value-added: The curtain area can reach more than 50 m², and the high-definition spray-painted corporate LOGO can become a mobile billboard on the highway, saving tens of thousands of yuan in offline promotion costs a year.
In a word: The side curtain tarpaulin is a "lightweight armor", which combines the protection of traditional vans, the convenience of warehouse trucks, and the communication functions of advertising trucks while maintaining the weight advantage of the whole vehicle.
