The BÖSE BACK-TOP-SIDER is a superstructure designed for three-sided loading. On the side, this superstructure combination is equipped with the well-proven Submatik roofed-in system. The roof construction consists of a sliding cover. The BÖSE system enables rapid loading and unloading at the side. Alternatively, in case of closed side walls, freight can be taken via the opened sliding cover, where rear portal and roof are continuously opened. The possible applications are extended by that, since diverse transport tasks can be realised with only one vehicle. The superstructure can be employed for crane loading both in the beverage transport sector and in the forwarding agency sector. The multi-winged door attached at the rear (optional) enables freight with excess lengths.
