Curtain semi-trailer or curtain-type semi-trailer is one of the most flexible types of semi-trailers. Its design allows loading not only on the sides, but also from the rear or from above, using a roof sliding in both directions. This solution makes loading and unloading significantly faster and allows even more efficient use of the cargo space inside the vehicle. This is the reason behind the popularity of curtain semi-trailers. The main advantages of our curtain trailers include: reinforced and stable frame design, lifted roof and easily separable, tight tarpaulin. The cargo area of our MEGA FIRANKA trailers allows cargo to be transported at levels reaching up to 3m and quickly separating tarpaulin, sliding and hydraulically lifted roof and rear doors enable quick loading and unloading.
