Product Description

A curtain-sided semi-trailer, also known as a curtain-sider, is a versatile freight transport vehicle characterized by its flexible side curtains and reinforced aluminum framework. The primary structure features durable polyester or PVC-coated fabric curtains tensioned across an extruded aluminum roof bow system, providing weather-resistant protection while enabling full lateral access to cargo. 

Key components include:
1. Retractable curtain mechanisms with heavy-duty zippers and twist locks
2. Reinforced load-bearing chassis with ISO-standard corner castings
3. Anti-billowing safety systems with webbing straps and ratchet tensioners
4. Removable front bulkhead and rear roller shutter door configurations

This design combines the security of rigid walls with the operational flexibility of open-platform trailers, allowing rapid side-loading through complete curtain retraction. The lightweight aluminum superstructure (typically 6,500-7,500 kg tare weight) maximizes payload capacity while maintaining aerodynamic efficiency. 

Common applications include:
- Palletized freight distribution
- Temperature-controlled logistics (with insulated curtain variants)
- Cross-docking operations
- Oversized equipment transport

Safety features comply with ECE R73 regulations, including side-underrun protection and reflective conspicuity markings. Modern variants incorporate telematics-ready designs and LED lighting systems for enhanced operational visibility.
