In addition to Schmitz and Krone, Kässbohrer, Talson, van Eck and Groenewegen also manufacture closed semi-trailers. All models basically have the same structure; a large closed space with lockable loading doors at the rear. To make the loading/unloading more efficient, trailers can be equipped with the following options: lift axle, steering axle, tailgate, underfold tailgate, side door, double doors (front and rear) or swing doors. Swing doors are rear doors that can be hinged at an extra point so that the doors can also be opened in tight spaces.
Due to their universal nature, closed trailers are suited for transporting a large number of different goods. The advantage of closed semi-trailers is that the contents are sealed airtight from the outside world. This is important, for example, for products that are not resistant to moist. In addition, the load is better protected against theft compared to curtainsider semi-trailers.
The price of second-hand closed semi-trailers varies widely. The appearance and technical condition of the trailer determines the price. A brand-new unit obviously costs more than an older one. BAS World always has a large selection of different brands and models in stock. You can buy a closed trailer for €3,000 from BAS. The price of a new unit is around €25,000.
