1. Overview

The 3-axle curtain side semi-trailer combines the weather protection of a box van with the loading flexibility of a flatbed. The sliding tarpaulin curtains provide full side access, allowing forklifts to load/unload pallets directly from the sides. This design is ideal for LTL (less-than-truckload) operations, palletized freight, and distribution centers where fast turnaround is critical. Built with a lightweight aluminum or steel frame and durable PVC curtains.

2. Key Features

Key tips:

• Max payload (light cargo, high volume) → Choose Aluminum Lightweight – saves 1,000+ kg tare weight

• Fragile / high-value cargo → Choose Air Suspension Premium for smooth ride

• Frequent side forklift loading → Ensure curtains have reinforced edges and easy-slide tracks

• Wet / rainy regions → Upgrade to 900 g/m² PVC curtain with sealed seams

• Overhead crane loading → Choose sliding tarpaulin roof option
